一、完形填空In ancient times, the Four Great Inventions in China had a great influence on the whole world. In recent years, China once again has 1 its ability to change the world with its “four great new inventions”: high-speed railways, mobile payment, bike-sharing and online shopping.Do you know 2 the new inventions can appear in China The “four great new inventions” are 3 related to China’s high-tech innovation (创新). For example, the operating mode of bike-sharing is based 4 the satellite navigation system (卫星导航系统), mobile payment, big data and other high technologies. This shows that China’s high-tech innovation has greatly 5 the quality of people’s lives.China has entered a new innovative era, thanks to the large amount of 6 that China has spent encouraging innovation. China is beginning to 7 in innovation in some ways.“The ‘four great new inventions’ have surely improved customer experience, and helped national and global(全球的) economy 8 at the same time,” said Charlie Dai, principal analyst (首席分析师) of an American market research company.As a whole, all the Chinese are 9 of their four new inventions. It is increasingly clear that China is innovating and no longer copying western ideas. More and more foreigners 10 to promote (促进) economic development in their countries by learning from China’s innovation.1．A．seemed B．appeared C．looked D．showed2．A．when B．what C．why D．where3．A．all B．both C．neither D．none4．A．in B．on C．to D．from5．A．improved B．finished C．invented D．wasted6．A．people B．water C．electricity D．money7．A．try B．lead C．win D．value8．A．develop B．warn C．mean D．live9．A．proud B．tired C．bored D．satisfied10．A．afford B．repeat C．hope D．wait二、任务型阅读You may think that inventions are far away from your everyday life. But in fact almost everyone can invent. It’s just that they do not recognize that their ideas could be the start of an invention.Once inventors see their ideas have some practical value they don’t let them slip away.For example, the inventor of the dishwasher American Josephine Cochrane loved to give dinner parties. But she found it took long to wash her dishes by hand and too many of them broke. She decided that a machine could do the job faster and with fewer mistakes. So in 1886 she set out to make one for herself.Cochrane’s most wonderful inventions are created to solve the problem. So the first and most important step is to find the problem.You can start by looking at what is wrong with the things you are using now. You can ask grandparents or neighbors if they remember ever saying: “I wish someone would invent something for ...” Or you can look at people in different areas — such as on the street or at school. Then you might notice situations or things in need of improvement. Remember to record your ideas and work. This will help you develop your invention and protect (保护) it when it is completed.The next step is to think about possible solutions. An invention is a new way of solving a problem. So think of many varied (各种各样的) and unusual ways. You can often come up with a solution to a problem by looking at it from a different angle (角度) or thinking about it in a new way.And the hardest part of inventing even for a lot of inventors is finding a problem and coming up with a solution. Once you have an idea you can always get help to build your invention.This problem-solving technique can also work in your everyday lives. So why not try it in your studies, in your relationship with others or even in the way you look at the world 1．完成句子。Josephine Cochrane found it took long to wash her dishes .2．用英语表达文中画线单词one所指代的内容： _________________________________________________ 3．找出并写下第四段的主题句。 ________________________________________________ 4．What is the hardest part of inventing ____________________________________________________ 5．将文中画线句子翻译成汉语。 ______________________________________________________________ 三、七选五Your brain controls everything you do. It makes it possible for you to think, learn, create and feel; to blink(眨眼) and breathe and for your heart to beat—this fantastic control center is your brain. 1.______Can this small grey organ(器官)，which weighs less than one and a half kilos, really do so much Amazingly, your brain contains about 100 billion neurons(神经元）—it would take you over 3,000 years to count them all. 2.______ Your neurons create and send more messages than all the phones in the world. And although one neuron creates only a little electricity, all your neurons together can produce enough electricity to power a light bulb(灯泡).So exactly how fast does your brain work 3.______ Neurons in your skin send this information to your brain at a speed of more than 240 kilometers per hour. Your brain then uses other neurons to send the message back to your foot to shake the bee off quickly. 4.______ No computer has your brain’s unbelievable ability to deal with the amount of information coming from your eyes, ears and other sensory organs. But how does your brain allow you to learn things that you will use in the future The structure(结构) of your brain changes every time you have a new thought, remember or learn something. 5.______ How As you practice, your brain sends “bike riding” messages again and again. Soon, the actions are learnt and you are able to ride a bike easily from then on.A. Well, imagine this: a bee lands on your foot.B. Therefore, it is not surprising to see that somebody with average intelligence (智力) can have excellent performances in some fields.C. Believe it or not, the activity in your brain never stops.D. It is so amazing that a famous scientist once called it “the most complex (复杂) thing we have yet discovered in our universe”.E. The brain is the boss of the body．F. These neurons can send this information at more than 320 kilometers per hour. G. For example, riding a bike seems impossible at first, but soon you are able to do it.四、根据语篇内容，从方框中选择恰当的单词，并用其正确形式填空。每个单词只能用一次。problem strange small When your laugh eat drink one coldI’m Henry, from America.

The next time I needed to blow my nose, I left the table and went to the toilet. 6 I returned, it was nearly time to leave. I noticed there were some 7 bowls with water in them on the table. It smelt good and I started 8 it before it got cold. Then I saw some of my colleagues cover their mouths.

At first, I was quite happy and learned to use chopsticks with them”及备选词可知，应是请作者出去吃饭，eat out“在外面吃饭”，不定式符号to后跟动词原形，故填eat。2．句意：起初，我很高兴，学会了用筷子，但后来问题开始了。根据下文“ I felt uncomfortable with my nose, so I turned away from the table and blew my nose （鼻子）...They explained to me that in Japan, people don’t blow their noses in public-especially at table.”可知，应是出现问题了，problem“问题”，空前无限定词，所以此处用名词的复数形式，故填problems。3．句意：那天，我感冒了。根据“I felt uncomfortable with my nose, so I turned away from the table and blew my nose （鼻子）”及备选词可知，应是感冒了。have a cold “感冒”，故填cold。4．句意：同事们奇怪地看着我。根据“They explained to me that in Japan, people don’t blow their noses in public-especially at table.”可知，在日本，人们不会在公共场合擤鼻涕，尤其是在餐桌上，所以作者在吃饭时擤鼻涕，大家应是很奇怪，strange“奇怪的”，空处修饰动词looked，所以用副词形式。故填strangely。5．句意：当我试图把筷子插进饭碗里时，我的一位同事说。根据“...of my colleagues said”及备选词可知，应是其中一位同事说，one of“……之一”，故填one。6．句意：当我回来的时候，差不多是该离开的时候了。根据“...I returned, it was nearly time to leave”可知，空指回来的时候，备选词when符合语境，引导时间状语从句。故填When。7．句意：我注意到桌子上有一些盛着水的小碗。根据“ some ...bowls with water ”及备选词可知，此处指“小碗水”，small“小的”作定语修饰名词bowls，故填small。8．句意：它闻起来很香，我在它变冷之前就开始喝了。根据上文的“water ”和“It smelt good and I started... it ”及备选词可知，应是闻起来很香，所以把水喝了，drink“喝”，start doing sth“开始做某事”，故填drinking。9．句意：他们强忍着不笑出来。根据“Then I saw some of my colleagues cover their mouths. ”及备选词可知，他们忍着不笑，laugh“笑”，to后跟动词原形，故填laugh。10．句意：这是用来洗手指的。空处作定语修饰名词fingers，结合备选词your“你的”符合语境，指的是“小碗里的水是用来洗手指的”，故填your。
