Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.
Recently, there’s been a lot of talk in U.S. about the “data problem.” It ought to give the “datadriven” school reformers pause to reconsider. Maybe we are just creating a bubble that too will burst if we continue to base our actions on the belief that only scores on standardized instruments are evidence of success.____47____ Margo, a famous commenter, states that at least tests are more “reliable” than professional judgment. How can she tell We want a nation of citizens who are less ready to think that the “truth” can only be captured in one of four answers—a, b, c, or d. ____48____ But how can the general trend guarantee the reliability of the score of one particular test-taker Some educator dares to replace these tests with professional human judgments, which must still rest on a numerical rank order based on a, b, c and d. The big problem is that there is often no technical assurance for the reliability of such exams. No wonder many big-name psychologists avoid them.
All “reliability” tells us is that the student would get a similar score on a similar test if given at another time or place. But all scores on old or new tests have measurement errors. Like Wall Street’s numbers, we have no independent basis for relying on these scores. Likewise, validity is in the eye of a certain standard of judgments. How ridiculous it is to say for sure that these judgments are justified!
When some parents told me that their children seemed to read well, but scored poorly, they often believed the indirect evidence, test score, and not the direct evidence, listening to their children read. Some parents had been trained to distrust judgment and rely on “real evidence”. My own 8-year-old son also used to “fail” a 3rd grade reading test even though I “knew” he could read fluently. ____49____
We need schools that “train” our judgment, which help us become adults who are in the habit of bringing judgment to bear on complex phenomenon. ____50____ It also involves acknowledging that even experts must live with a substantial degree of uncertainty. Only in this way, can we, to some extent, rely on the results of the school education in the U.S.
A. Even the technical meaning of “good tests” is open to question.
B. It’s when I became a test doubter.
C. Different groups of people fit different test patterns.
D. On all achievement tests, we’re promised beforehand a population that fits a normal curve (曲线).
E. This includes judging which expertise to “trust” and defending such choices.
F. Time spent on standardized tests is, in many cases, equal to that on study.

Directions: Complete the following passage by using the sentences in the box. Each sentence can only be used once. Note that there are two sentences more than you need.
Many people drink protein shakes (高蛋白饮品) regularly to lose weight, build muscle or both. Others, however, question the belief that protein shakes are better than normal, high-protein foods. So what is the truth
What is in a protein shake
Protein shakes are dietary supplements (膳食补充品) designed to help people consume more protein than they otherwise would. ___47___ Or people can mix their own shakes using protein powder and other ingredients. Protein powder can be made from plants or animals. Plant-based protein shakes can include soy, pea or rice protein. Animal-based protein powders are usually made from cow’s milk. Those who want to stay away from milk can also get protein powder made from egg whites.
Advantages of protein shakes
Studies indicate that consuming protein shakes is helpful if you want to build your muscle. They can also help to improve your performance while exercising and help you to recover from exercise. ___48___
Consuming protein shakes can also help you lose weight. Eating a high-protein diet helps you feel full, so it’s easier to resist eating too much. High-protein diets can also increase how quickly your body burns energy. When you use more energy than you take in through food, you lose weight. ___49___
Disadvantages of protein shakes
However, you don’t have to drink protein shakes to have a high-protein diet. Many wholefoods are rich in protein. As a matter of fact, the people in many high-protein diet studies didn’t drink protein shakes The studies proved the benefits of eating protein-rich foods. ___50___ In contrast, many protein shakes contain sugar or artificial sweeteners, which are not healthy.
To sum up
So yes, protein shakes are convenient, and they work. However, they are not your only choice for eating a high-protein diet.
A. And if you’re losing weight, protein shakes can help make sure that you don’t lose muscle.
B. Protein shakes can also help people to manage their figures, especially their weight.
C. Moreover, these foods contain other nutrients in addition to protein.
D. Therefore, it is unnecessary to take protein shakes unless it is a must.
E. Protein shakes can be ready-made drinks.
F. And high-protein diets have also been linked to the loss of fat.

Directions: Read the fallowing passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.
Out-of-control SpaceX Rocket
A SpaceX rocket is now headed directly for the moon after spending almost seven years flying through space, experts say. The rocket was originally launched to send a space weather satellite to the Lagrange point— a gravity-neutral position four times farther than the moon and in direct line with the sun. ____47____
At this phase, it did not have enough fuel to return to Earth’s atmosphere. But meanwhile it lacked the energy to escape the gravity of the Earth-Moon system. ____48____ Space observers believe that it is on course to intersect (相交) with the moon. Bill Gray, who writes software to track near-Earth objects, has said the rocket will very likely hit the far side of the moon, near the equator. “This is the first unintentional case of space junk hitting the moon of which I’m aware,” Gray added.
____49____ Because of the unpredictable effect of sunlight “pushing” on the rocket and “difficulty in measuring rotation (旋转) periods”, its orbit may be slightly altered. “But these unpredictable effects are very small,” Gray wrote. He added that further observations were needed to decide the precise time and location of the impact. In a recent blog post, he wrote that the rocket has made a close lunar flyby, and will definitely make an impact.
As for whether the collision (相撞) could be viewed from Earth, Gray says it will probably go unobserved.” Even if it hit on the near side of the moon, the impact occurs a couple of days after New Moon, which was hardly observable, he added, “to me, the impact was not a big deal.” ____50____ They believe that the event will allow for observation of valuable lunar materials ejected (弹射) by the rockets strike.
A. So the rocket has been following a somewhat chaotic orbit since.
B. Nevertheless, space enthusiasts believe the impact could provide valuable data.
C. It was part of SpaceX’s space exploration programme.
D. But after completing a long burn of its engines, the rocket’s second phase became a problem.
E. The exact spot that the rocket will hit remains unclear.
F. The lunar phase reveals the passage of time in the night sky.

Section C
Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.
Eating meat is not a crime against the planet — if it’s done right
I have huge admiration for George Monbiot, a well-known columnist. His work has highlighted the urgent need to reduce our CO2 emissions and switch to greener energy. He has also shown intensive farming’s role in the dramatic levels of species decline and biodiversity loss. Much of what he writes is in line with my stand. ____67____
It is undeniable that the farming revolution of the 1950s has started a war on nature. These intensive ways of producing food are not only polluting our land and waterways, but are heating up our planet and contributing to a crisis in human health. We need to change the way we eat and produce food, and fast.
____68____But in a recent article, he wrote that organic, pasture-fed beef and lamb are the “world’s most damaging farm products.” He criticises “chefs and foodies” like me for focusing on regenerative grazing — farming that aims to repair, rebuild, revitalize and restore ecosystem function. His alternative vision includes a revolution in creating food in labs from microbes and water.
Although not opposed to the idea of lab-grown food, I am much more for small-scale community-driven farming.
____69____Methods that regenerative farmers propose have shown how non-intensive livestock, when managed well, can increase topsoil more than previously thought, which can then build up biomass (carbon) and keep precious rainwater. According to the Food and Agriculture Organization of the UN, small-scale farmers currently produce about a third of our food.
____70____These inventions in new food technology are heavily patented, pushing the future of our food supply further into the hands of an increasingly small and powerful collection of multinational food players. In our race to look for better systems of food production. We cannot afford to ignore the risks.
A. Thus far Monbiot and I agree.
B. Monbiot’s enthusiasm for creating food in labs worries me.
C. That is because I believe in the potential of food to be a force for good.
D. Regenerative farming has produced untested food through small-scale farms.
E. The health impact of processed foods gets very little attention from the government.
F. However, regarding the solutions needed to change our farming and food systems, we have different views.

I Am Not a Robot
An annoyance, an important security feature, an uncomfortable request: however you feel about being asked to prove you are not a robot, it has become a daily occurrence for most of us, but perhaps not one we would miss if it were to suddenly go away.
A new feature in the latest versions of iOS and macOS, Apple’s operating systems for smartphones and computers, promises to give the boot to “captchas” once and for all. ____47____
“Sometimes a captcha is just a button to press,” said Apple engineer Tommy Pauly. “But other times it can be a challenge to fill out.”
The term captcha is in fact an acronym (首字母缩略词) for “completely automated public Turing test (图灵测试) to tell computers and humans apart.” To help stop fraud (欺诈), these little tests often pop up when you’re signing up for or onto a website.
____48____ If you get it wrong, it may ask you to start again, leading you to wonder if you really know what a traffic light looks like—or if you might really be a robot after all.
But captchas are now fast becoming unusable, making the Internet a wasteland of difficult puzzles. Users must struggle to do the most basic things. “We’ve literally all found ourselves at one time or another complaining: ‘Those were all the pictures with traffic lights,” said Effie Le Moignan, a researcher in social computing at Newcastle University.
Internet users struggle to tell the difference between a wear of paint on a sidewalk and a formalized crosswalk that’s often requested in a traditional captcha, and worry that one wrong answer may lock them out of an account. ____49____
“You likely don’t enjoy being interrupted by these,” said Apple’s Tommy Pauly. “I certainly don’t. The reason these experiences exist is to prevent dishonest activity. If you run a server, you don’t want it to be defeated by fraud. ____50____”
The company worked with Fastly and Cloudflare to build the new feature. It works by allowing your device to send a statement confirming it is being used by a human to the requesting website.
A. This is becoming a bigger issue as captchas have grown increasingly confusing.
B. Therefore, when faced with something really confusing, many people simply give up.
C. Most attempts to create accounts or to buy products come from common users, but some attempts can also come from attackers.
D. Called “automatic confirmation,” the technology will allow sites to confirm you are not a robot without you having to do anything at all.
E. These tests may ask you to spot all the traffic lights in a picture or to type out some special letters and numbers.
F. Although the service is tied to Apple’s iCloud network, the requesting site will not receive any personal information about the user or their device.

Many wholefoods are rich in protein.(然而，你不一定要喝蛋白质奶昔来获得高蛋白饮食。许多天然食品富含蛋白质。)”再次提到高蛋白食物。故空处承上启下，也需要提到高蛋白饮食。F项“高蛋白饮食也与脂肪的减少有关。”中high-protein diet为原文复现。故选F项。
【50题详解】
上文“Many wholefoods are rich in protein. As a matter of fact, the people in many high-protein diet studies didn’t drink protein shakes The studies proved the benefits of eating protein-rich foods.(许多天然食品富含蛋白质。事实上，在许多高蛋白饮食研究中，人们并不喝蛋白奶昔。这些研究证明了食用富含蛋白质的食物的好处。)”讲了食物中的蛋白质，并提到关键词food“食物”，而选项中只有C项“此外，这些食物除了蛋白质之外还含有其他营养物质。”含有该关键词，为原文复现。故选C项。

【解析】
【导语】本文为说明文。文章介绍了一颗名为SpaceX火箭在太空飞行了近七年后，现在直接前往月球。根据科学家们的说法，火箭没有足够的燃料返回地球大气层，但也缺乏逃离地月系统引力的能量，预计会在2022年3月初与月球相撞，撞击可能会撞击月球背面，靠近赤道。
【47题详解】
根据前文“The rocket was originally launched to send a space weather satellite to the Lagrange point— a gravity-neutral position four times farther than the moon and in direct line with the sun.(火箭最初发射的目的是将一颗太空气象卫星发送到拉格朗日点，一个距离月球四倍远、与太阳成直线的重力中性点。)”和下一段第一句“At this phase, it did not have enough fuel to return to Earth’s atmosphere.(在这个阶段，它没有足够的燃料返回地球大气层。) ”可知，空格处的句子要承接上文，且要提及下文的“At this phase”，D选项“但在完成了引擎的长时间燃烧后，火箭的第二阶段就成了一个问题。”的“But”与前文的“originally launched to ”形成对比，表明出现了问题，引出火箭的第二阶段，选项中“the rocket’s second phase”即为下文提及的“At this phase”，符合语境。故选D项。
【48题详解】
根据前文“At this phase, it did not have enough fuel to return to Earth’s atmosphere. But meanwhile it lacked the energy to escape the gravity of the Earth-Moon system. (在这个阶段，它没有足够的燃料返回地球大气层。但与此同时，它缺乏逃离地月系统引力的能量。)”可知，在这一阶段，火箭遇到了进退两难的问题，横线处的句子要承接上文，A选项“因此，自那以后，火箭一直沿着一条有点混乱的轨道运行。”表明了不能回地球也不能离开月球的结果就是开始偏离轨道，承接上文，符合语境。故选A项。
【49题详解】
根据上一段最后一句““This is the first unintentional case of space junk hitting the moon of which I’m aware,” Gray added. (“这是我所知道的太空垃圾撞击月球的第一起无意案例，”格雷补充道。)”和后文“Because of the unpredictable effect of sunlight “pushing” on the rocket and “difficulty in measuring rotation (旋转) periods”, its orbit may be slightly altered.(由于阳光对火箭“推动”的不可预测的影响以及“难以测量旋转周期”，其轨道可能会略有改变。)”可知，偏离轨道导致会撞上月球，但因为有着难以测量的因素，所以不好精确地预测到底会撞击在月球哪个部位。E选项“火箭将击中的确切地点仍不清楚。”承上启下，符合语境。故选E项。
【50题详解】
根据前文“Even if it hit on the near side of the moon, the impact occurs a couple of days after New Moon, which was hardly observable, he added, “to me, the impact was not a big deal.”(即使它击中了月球的近侧，撞击也发生在新月之后的几天，这几乎是无法观察到的，他补充说，“对我来说，撞击没什么大不了的。”)”和后文“They believe that the event will allow for observation of valuable lunar materials ejected (弹射) by the rockets strike. (他们认为，这一事件将有助于观测火箭撞击所喷出的宝贵月球物质。)”可知，虽然这次撞击对于Gray 来说是没有意义的，但对于观察火箭袭击月球喷射是珍贵的材料。B选项“尽管如此，太空爱好者相信这次撞击可能会提供宝贵的数据。”中的“the impact could provide valuable data.”与后文“observation of valuable lunar materials ejected by the rockets strike”相对应，符合语境。故选B项。

Much of what he writes is in line with my stand.(我非常敬佩著名专栏作家乔治·蒙比尔特。他的工作强调了减少二氧化碳排放和转向绿色能源的迫切需要。他还展示了集约化农业在物种急剧减少和生物多样性丧失方面的作用。他写的很多东西都与我的立场一致)”结合后文论述了作者和乔治·蒙比尔特的不同观点，可知本句与上文构成转折。故F选项“然而，关于改变我们的农业和粮食系统所需要的解决方案，我们有不同的看法”符合语境，故选F。
【68题详解】
根据后文“But in a recent article, he wrote that organic, pasture-fed beef and lamb are the “world’s most damaging farm products.” He criticises “chefs and foodies” like me for focusing on regenerative grazing — farming that aims to repair, rebuild, revitalize and restore ecosystem function. His alternative vision includes a revolution in creating food in labs from microbes and water.(但在最近的一篇文章中，他写道，有机牧场饲养的牛羊肉是“世界上最具破坏性的农产品”。他批评像我这样的“厨师和美食家”专注于再生放牧——旨在修复、重建、振兴和恢复生态系统功能的农业。他的另一种设想包括在实验室里用微生物和水制造食物的革命)”可知，后文与本句构成转折，后文说明了观点的不同，可知本句是在说明二人都赞成的情况——即上文提到的“It is undeniable that the farming revolution of the 1950s has started a war on nature. These intensive ways of producing food are not only polluting our land and waterways, but are heating up our planet and contributing to a crisis in human health. We need to change the way we eat and produce food, and fast.(不可否认，20世纪50年代的农业革命已经开始了一场对自然的战争。这些密集的粮食生产方式不仅污染了我们的土地和水道，而且使我们的地球升温，并导致人类健康危机。我们需要改变饮食和生产食物的方式，而且要快)”。故A选项“到目前为止，Monbiot和我都同意”符合语境，故选A。
【69题详解】
根据上文“Although not opposed to the idea of lab-grown food, I am much more for small-scale community-driven farming.(虽然我不反对实验室种植食物的想法，但我更支持小规模的社区农业)”可知，本句承接上文说明作者支持小规模社区农业的原因，故C选项“那是因为我相信食物有潜力成为一种向善的力量”符合语境，故选C。
【70题详解】
根据后文“These inventions in new food technology are heavily patented, pushing the future of our food supply further into the hands of an increasingly small and powerful collection of multinational food players. In our race to look for better systems of food production. We cannot afford to ignore the risks.(这些新食品技术的发明获得了大量专利，将我们食品供应的未来进一步推向了越来越小而强大的跨国食品公司的手中。在我们寻找更好的粮食生产系统的竞赛中。我们不能忽视这些风险)”可知，后文主要说明了新食品技术发明的风险，即作者的担忧。故B选项“Monbiot在实验室创造食物的热情让我担心”符合语境，故选B。

【49题详解】
根据前文“Internet users struggle to tell the difference between a wear of paint on a sidewalk and a formalized crosswalk that’s often requested in a traditional captcha, and worry that one wrong answer may lock them out of an account.(互联网用户很难分辨人行道上油漆的磨损和传统通行证中经常要求的正式人行横道之间的区别，并担心一个错误的答案可能会让他们无法登录)”可推知，空处应是对此句话下结论，所以B项“Therefore, when faced with something really confusing, many people simply give up.(因此，当面对一些真正令人困惑的事情时，许多人就放弃了)”符合文意。故选B项。
【50题详解】
根据前文“I certainly don’t. The reason these experiences exist is to prevent dishonest activity. If you run a server, you don’t want it to be defeated by fraud.(我肯定不喜欢。这些体验存在的原因是为了防止不诚实的行为。如果您运行一个服务器，您不希望它被欺诈打败)”此处属于引用他人说的话，话还未说完，可推知，空处应该是对这些体验存在原因进一步解释，所以C项“Most attempts to create accounts or to buy products come from common users, but some attempts can also come from attackers.(大多数创建账户或购买产品的尝试都来自普通用户，但也有一些尝试来自攻击者)”符合文意。故选C项。
