Do you like delicious blueberries If so, when you eat next time, take a look at them. Are they really blue
Not really. Once taking off its skin, the inside is white. Rub (摩擦) the inside of a blueberry on a white piece of paper. It is reddish-purple. And if you rub the outside of a blueberry, it gets almost black. But the moment you pick one, it does look blue. Why
①The first way is through “structural color” (结构色).②The blueberry makes “structural color” in its own way. ③When the blueberry is fully grown, it is black. ④But a thin layer of wax (蜡层), on the outside of the blueberry, gives it a blue look.
The second is through plant pigments (色素). The pigments on the blueberry skin take in green and yellow light and reflect (反射) blue light. That’s why blueberries look blue in our eyes. In fact, there aren’t any “true blue” in the plants. We can also see something similar on the green leaves.
The blueberry’s special color way is cool. It shows nature’s magic. More secrets in our nature are waiting for us to discover! Now your bowl of blueberries suddenly looks a lot more interesting!
26．According to paragraph 2, after you rub the outside of a blueberry, it almost looks ________.
A．blue B．black C．white D．reddish-purple

Many people think that it is good for an elderly (年老的) person to keep a pet. Elderly people may miss their friends and family who are no longer around. However, a kitten (a young cat) for an elderly person is not a good idea.
Kittens are tiring. Elderly people, even those in the best of health, will have a lot of difficulties running after a kitten and, unluckily, kittens do need a lot of care. They need to be trained not to destroy homes and not to run up curtains (窗帘), and they need a lot of fun-time which an elderly person may not be able to give them. And an elderly person will not want to look for the cat. It needs much energy.
________________ But kittens can be really expensive. They need to be taken to the animal doctors for health checks, especially when they are young. Cat food is usually expensive, and their beds, toys and other things all cost much money. For an elderly person living on a pension (退休金), the cost can be more than they can afford.
If an elderly person really wants an animal friend, an older cat would be a much better choice. Getting one from a cats’ home should make sure that it is already well trained. And with a little bit of care, it will live in a home with an elderly person.
Elderly people should carefully think about anything that may lead to extra stress (压力). So think of other ways for them to live a better life.
31．What does the writer want to do in Paragraph 1
A．To advise the elderly not to miss their friends. B．To introduce the elderly to a pet gift.

D．Kittens are often more popular than older cats.
34．What can we learn from Paragraph 3
A．The older cats grow, the more they cost.
B．The cost of taking care of kittens is high.
C．The health checks are useless when a kitten grows up.
D．The elderly people can keep any kitten as a pet.

A two-legged tortoise (龟) is running faster after getting a set of wheels (轮子). The animal, named Mrs. T, faced a terrible life in a winter-a mouse (老鼠) ate her two front legs when she was sleeping!

In fact, rats (老鼠) attacking (袭击) tortoises is nothing special in UK in 2013 the oldest tortoise, Thomas, was attacked by rats at his home. His owner and doctors tried their best to (尽全力) save him after the attack, but the 130-year-old tortoise didn’t make it.

参考答案及试题解析
1．D
【解析】句意：我妈妈正在厨房做晚饭。
cook动词原形；cooks动词三单形式；are cooking现在进行时复数形式；is cooking现在进行时单数形式。主语My mother是第三人称单数，排除A、C。虽然句中没有明显的时间标志词，但此类语境通常描述此刻正在发生的动作，应用现在进行时。
2．C
【解析】句意：老师和学生们现在正在公园打扫卫生捡垃圾。
lean一般现在时；cleans单三形式；is cleaning现在进行时（单数）；are cleaning现在进行时（复数）。分析原句结构可知，当主语后面跟有with引导的短语时，谓语动词的数应与with之前的中心词保持一致。本语境中的真正主语是The teacher，为第三人称单数，谓语动词需用单数形式，由此可排除A、D两项。结合语境，此处描述他们正在进行的活动，应用现在进行时的单数形式is cleaning。
3．D
【解析】句意：——吉姆在哪里？——他爸爸昨天给他买了一辆自行车，现在他正在外面骑自行车。
考查动词时态。根据“yesterday”可知，第一空所在句用一般过去时，动词用过去式；根据“now”可知，第二空所在句用现在进行时，动词用现在分词形式。故选D。
4．B
【解析】句意：——你的笔友来自哪里？——他来自加拿大。
考查短语辨析。结合语境及答句“He’s from Canada.”可知，该句在询问对方的笔友来自哪里，“来自”的英文表达可以为短语“come from”或“be from”。再结合备选项及题干“…from”可知，介词from前空缺一词，问句中应用短语“come from”，且该句主语“your pen pal”为第三人称单数形式，则特殊疑问句中应用助动词does。故选B。
5．D
【解析】句意：——海伦，你能帮忙接一下电话吗？我正在洗碗。——好的，爸爸。
考查时态及主谓一致。根据“Helen, can you help answer the phone, please ”可知，空处是表明自己正在洗碗，无法接电话，因此用现在进行时am/is/are doing，主语是I，be动词用am。故选D。
6．A
【解析】句意：哎呀！我的手表坏了。你能把你的手表借给我用一下吗？
考查动词辨析。lend借给；use使用；borrow借入；pick挑选。根据“My watch doesn’t work. Could you please ... me yours ”可知，此处是请求对方借给自己手表。故选A。
7．C
【解析】句意：——马克，你弟弟在哪里？——他正在外面和他的朋友们堆雪人。
考查动词时态辨析。根据语境可知，问句询问弟弟当下在哪里，回答应是正在进行的动作，现在进行时结构为“be+现在分词”。主语He是第三人称单数，be用is，make的现在分词是making。故选C。
8．D
【解析】句意：纸是由木材制成的，那条围巾是由丝绸制成的。
考查介词辨析。be made of由……制成，强调能看出原材料；be made from由……制成，强调加工后看不出原材料。第一空木材制成纸（看不出原料），用“from”；第二空丝绸制成围巾（可见原料），用“of”。故选D。
9．A
【解析】句意：看！那个在河中游泳的男孩处于危险中。我们赶快去救他。
考查介词短语。in danger在危险中；on time按时；on duty值日；for example例如。根据“The boy swimming in the river is ... Let’s go and save him.”可知，发出快去救他的指令，说明男孩处于危险中。故选A。
10．B
【解析】句意：中国的屏风始于汉代。它最初的意思是防风。
考查动词短语辨析。comes from来自；dates from追溯到，始于；hears from收到……的来信；learns from向……学习。根据“The Chinese Pingfeng...the Han Dynasty.”可知，此处指屏风始于汉代，所以应该用dates from。故选B。
11．A 12．D 13．B 14．C 15．B 16．D 17．A 18．A 19．C 20．B
【导语】本文通过Ryzhiy的故事，展现了动物与人类的深厚友谊及其社会价值。

14．句意：她在儿子14岁生日时送给他一只名叫Ryzhiy的狗作为礼物。
choice选择；result结果；gift礼物；goal目标。根据“on his 14th birthday”可知，此处指生日礼物。故选C。
15．句意：但是Ryzhiy作为宠物狗的日子并没有持续多久。
And和；But但是；Or或者；So所以。根据“Ryzhiy’s days as a pet dog don’t last long.”和上文可知，Olga Chumarova把Ryzhiy作为生日礼物送给了儿子，Ryzhiy作为宠物的日子不长，前后表示转折关系，所以用连词But。故选B。

31．细节理解题。根据“Many people think that it is good for an elderly (年老的) person to keep a pet. However, a kitten (a young cat) for an elderly person is not a good idea.”可知，作者先陈述大众观点，即很多人认为老人养宠物好，随后通过“However”进行转折，指出小猫不适合老人饲养，意在纠正人们认为所有宠物都适合老人这一错误观念。故选C。
32．词句猜测题。根据“kittens do need a lot of care. They need to be trained not to destroy homes and not to run up curtains, and they need a lot of fun - time which an elderly person may not be able to give them”可知，前文一直在阐述小猫需要大量照顾，需要被训练等内容，所以此处“them”指代的是前文提到的 “kittens”，即小猫。故选A。
33．推理判断题。根据“But kittens can be really expensive. They need to be taken to the animal doctors for health checks, especially when they are young. Cat food is usually expensive, and their beds, toys and other things all cost much money”可知，后文详细说明了照顾小猫在健康检查、食物、用品等方面花费高昂，因此空白处应填入与照顾猫成本相关的句子，A 选项“照顾任何年龄的猫都不便宜”符合语境，能自然引出后文。故选A。
34．细节理解题。根据“kittens can be really expensive. They need to be taken to the animal doctors for health checks...Cat food is usually expensive, and their beds, toys and other things all cost much money”可知，文中从医疗检查、食物、用品等方面具体说明了照顾小猫的费用非常高，所以可以得出照顾小猫成本高昂的结论。故选B。
35．主旨大意题。根据“If an elderly person really wants an animal friend, an older cat would be a much better choice. Getting one from a cats’ home should make sure that it is already well trained. And with a little bit of care, it will live in a home with an elderly person”可知，该段开头便点明主旨，指出如果老人想养宠物，年长的猫是更好的选择，后文围绕年长的猫已受过训练、易于照顾等优点展开，进一步说明其适合老人饲养。故选C。
36．C 37．A 38．D 39．A 40．D
【导语】文主要讲述了一只名叫Mrs. T的两条腿的乌龟在失去两条前腿后装上轮子，重新能够快速移动的故事，以及其主人为保护它所做的努力和相关背景信息。
36．细节理解题。根据第一段中“A two-legged tortoise is running faster after getting a set of wheels. The animal, named Mrs. T, faced a terrible life in a winter-a mouse (老鼠) ate her two front legs when she was sleeping!”可知，Mrs. T得到轮子是因为老鼠吃掉了它的两条前腿。故选C。
37．细节理解题。根据第三段中“Luckily, Mrs. Ryder’s son Dale made a set of wheels for Mrs. T.”可知，为了帮助Mrs. T过上更好的生活，Ryder夫人向她的儿子Dale求助，让他为Mrs. T制作了一套轮子。故选A。
38．推理判断题。根据第四段中“At the age of 60, Mrs. T came to the family as a pet for Dale on his 8th birthday. Now he is 33”可知，Dale现在33岁，从8岁到33岁经过了25年，而乌龟来的时候是60岁，所以现在乌龟是60+25=85岁。故选D。
39．推理判断题。根据最后一段中“Mrs. Ryder said she would find more ways to watch her garden and take better care of Mrs. T’s safety.”可知，Ryder夫人说她会找到更多方法照看她的花园并更好地照顾Mrs. T的安全，由此可推断出Ryder夫人仍然担心Mrs. T的安全。故选A。
40．主旨大意题。文章主要围绕一只名叫Mrs. T的两条腿的乌龟展开，讲述了它失去前腿后装上轮子的经历以及主人对它的照顾等情况，所以作者写这篇文章是为了讲述关于这只两条腿乌龟的故事。选项D“讲述一个关于一只两条腿乌龟的故事”符合文章主旨。故选D。

42．根据“Some of these animals might have been caught (抓捕) from the wild.”可知，此处需进一步解释为何要避免此类行为。选项E“人们可能不会好好照顾它们。”符合语境。故选E。
43．根据“For example, teeth, feathers, seashells, coral, and especially ivory.”可知，后文举例“牙齿、羽毛、象牙等制品”，并指出“制作过程伤害动物”。选项D“不要购买用动物器官制成的纪念品。”符合语境。故选D。
44．根据“That’s because lights may cause the birds to hit the windows or fly in circles.”可知，此处需解释原因。选项C“明亮的灯光会使鸟类在夜间感到迷惑。”符合语境。故选C。
45．根据“Some people are scared of animals like wolves, sharks and try to harm them”可知，后文提到“狼、鲨鱼等动物被误解”，并呼吁“宣传它们的重要性”。选项A“支持‘可怕的’动物。”符合语境。故选A。

【导语】本文介绍了植物的种子是如何传播的。
46．句意：植物不能像动物那样行走。walk“行走”，动词，句中情态动词“can’t”后面跟动词原形。故填walk。
47．句意：有些植物的种子非常轻。seed“种子”，可数名词，根据句中主语“Some plants”可知，此处用复数。故填seeds。

55．句意：然后它们就找不到它们了。they“它们”，人称代词主格，此处指代前面提到的“the nuts”，使用宾格them作谓语动词“find”的宾语。故填them。

60．句意：当我在旅馆的时候，我喜欢坐在树上喂长颈鹿。根据“at the hotel”可知，此处表示“在某地”，句子时态为一般过去时，主语是I，备选词be的过去式was符合语境。故填was。
61．句意：长颈鹿似乎无处不在。根据后句“People can see them in zoos.”可知，人们在动物园能看到长颈鹿，说明它们好像到处都有，备选词everywhere“到处”符合语境。故填everywhere。
62．句意：然而，它们正处于危险之中。前句说长颈鹿似乎无处不在，后句说它们处于危险中，前后句是转折关系，备选词however“然而”符合语境，句首首字母需大写。故填However。

70．开放性试题，答案合理即可。参考答案为：I feel happy because Christian went free.
71．例文：
Dear Alice,
I’m glad to receive your letter. My favourite animals are pandas. They’re white and black. They like climbing trees.
But their situation is difficult. They’re in danger. First, pandas don’t have many babies and baby pandas often die. Second, pandas eat bamboo, but the bamboo forests are getting smaller and smaller. So we should do something for pandas. We can set up nature parks and plant more bamboo so that pandas can have enough food. It’s also a good idea to raise money for them.
I hope everyone can protect them.
Yours,
Wang Yiming
