六、阅读理解。
①It is very cold in winter in some places. Snow and ice cover the ground. It is hard for animals to find food during these cold days. They get through the hard time in many ways.
②Some birds fly to other places. Many of them leave before winter comes. They travel to warm places and come back in spring. We call it migration (迁徙). It’s a good way for them to get away from the cold weather.
③Another good way to get through winter is sleeping. Some animals, such as snakes and bears, hide (隐藏) themselves in safe places and sleep through the whole winter. We call it hibernation (冬眠).
④Some animals, like squirrels (松鼠), ★ lots of food in their homes before winter. When it gets cold, they stay indoors and hardly go out.
⑤Other animals have to live in the cold winter. Some animals have thick fur (皮毛) to keep warm in winter while some change the colour of the fur. Arctic foxes are brown in summer but their fur turns white in winter.
1．Which of the following animals travel to other places before winter
A．Foxes. B．Squirrels. C．Bears. D．Birds.
2．How do snakes live in winter
A．By changing their colours. B．By sleeping through winter.
C．By traveling to warm places. D．By keeping food before winter.

Hundreds of years ago, no dandelions (蒲公英) grew in North America. Then people came from Europe. They had dandelion seeds on their clothes. The seeds fell from their clothes onto the ground. 5 . Most people believe that dandelions are weeds. They do not want them in their gardens. 6 .
7 . If the winter is not very cold, their leaves may stay green. 8 . Each night their bright yellow flowers close up. When the sun shines the next day, they open up again. After several days, the yellow flower turns white and soft. A tiny brown seed forms at the bottom of each white petal (花瓣). When the wind blows, the petals float away.
Each white petal carries a seed away. This lets the dandelions spread their seeds all over. 9
A．But some people think that dandelion flowers are pretty.
B．New dandelions grow where the seeds land.
C．When the spring arrives, their flowers come out.
D．Dandelions have beautiful yellow flowers.
E．Since then, dandelions have spread all over.

阅读下面材料，根据材料内容，完成下列各题。
Do you know something about tree rings (年轮) Do you know they can tell us what the weather was like, sometimes even hundreds of years ago
A tree will grow well in a climate (气候) with lots of sunshine and rainfall. And little sunshine or rainfall will limit (限制) the growth of a tree. We can see the change of climate by studying the tree rings. For example, to find out the weather of ten years ago, count the rings of a tree from the outside to the inside. If the tenth ring is far from the eleventh ring, then we’re sure that it was sunny and rainy most of that year. If it is near to the eleventh ring, then the climate that year was bad.
Tree rings are important not only for studying the history of weather but also for studying the history of man. Many centuries ago there lived a lot of people at a place in New Mexico. But now you can find only sand there — no trees and no people. What happened
A scientist studied the rings of dead trees there. He found that the people had to leave because they had cut down all the trees to make fires and buildings. As all the trees had gone, the people there had to move.

【导语】本文介绍了动物在寒冷冬季的不同生存策略：鸟类通过迁徙到温暖地区；蛇和熊等动物冬眠；松鼠提前储存食物；其他动物如北极狐则依靠厚毛或改变毛色适应寒冬。
1．细节理解题。根据“Some birds fly to other places. Many of them leave before winter comes.”可知，一些鸟飞到其他地方。它们中的许多在冬天来临之前离开。故选D。
2．细节理解题。根据“Some animals, such as snakes and bears, hide themselves in safe places and sleep through the whole winter. We call it hibernation.”可知，一些动物，比如蛇和熊，把自己隐藏在安全的地方，睡过整个冬天。我们称之为冬眠。选项B“通过睡过冬天”，符合蛇冬眠的描述。故选B。
3．词句猜测题。根据“Some animals, like squirrels, ★ lots of food in their homes before winter. When it gets cold, they stay indoors and hardly go out.”可知，一些动物，像松鼠，在冬天前在它们家里……很多食物。当天气变冷时，它们待在室内几乎不出去。松鼠是储存食物过冬，因此此处使用“store”表示“储存”，符合语境。故选A。
4．篇章结构题。根据文中内容可知，第①段总述动物在寒冷的冬天很难找到食物，它们以多种方式度过艰难时光；第②-⑤段分别介绍了不同的过冬方式，如鸟的迁徙、蛇和熊的冬眠、松鼠储存食物、其他动物通过皮毛保暖或改变皮毛颜色等。所以文章是总分结构。故选A。

【导语】本文是一篇说明文。文章主要介绍了河马的习性与特征。
10．句意：就像人类、狗和鲸一样，它是一种哺乳动物。
With和……一起；Unlike不像；Such如此；Like就像……一样。根据“...humans, dogs, and whales, it is a mammal (哺乳动物).”可知，此处表示河马和人类，狗，鲸一样都是哺乳动物，故选D。
11．句意：也就是说，它的孩子生下来就是活着的，并且它们喝母亲的奶水。
stayed待着；left离开，剩下；born出生。由本句“babies ”提示，以及“…and they drink milk from the mother’s body.”可知，此处表示小河马出生的情况，故选D。
12．句意：它大约重四吨，或者说四千千克。
reaches到达；weighs重；owns拥有；runs跑步。由本句“about four tons, or 4, 000 kilograms”可知此处是在讲河马的体重，故选B。
13．句意：它是个哺乳动物，但是它花很多时间待在水里。
spends花费，主语一般是人；takes花时间，主语一般是物；costs花钱，主语一般是物；pays付钱，主语一般是人。本句主语是it，因此用takes，故选B。

15．句意：然后它到水下找一些植物作为食物，它从来不抓鱼或者猎取其他动物。
vegetables蔬菜；fishes鱼；plants植物；insects昆虫。根据“and never catches fish or hunts other animals”可知河马不是食肉动物，而是食草动物，因此它到水下是找植物来吃，故选C。
16．句意：它可以关闭鼻子，并且在水下待十分钟。
above在……上方；on在……表面；under在……下面；beside在……旁边。结合语境可知此处是表示河马在水下的习性，故选C。
17．句意：它可以保持身体在水下，只有耳朵，眼睛和鼻子在水面上方。
under在……下面；beside在……旁边；above在……上方；on在……表面。根据下文“Then it can breath the air.”可知此时河马可以呼吸，证明此时河马的鼻子不在水下，而是在水面上方。故选C。
18．句意：它从来不会远离水。
far from远离；long enough足够长；close to接近；near by附近。结合全文语境可知，河马离不开水，故选A。
19．句意：婴儿河马可以站在妈妈的背上——脖子和腿中间的位置。
stomach胃；back后背；mouth嘴巴；head头。根据“the part of the body between the neck and legs”可知这里表示的是脖子和腿之间的后背的位置。故选B。
