五、阅读理解
A
We are always told that each of us should drink at least eight glasses of water every day. But most people drink less than six glasses. Even some drink one glass in the morning and one glass in the afternoon. If you do sports, you will need to drink more because you lose a lot of water.
A new Australian study shows that older people do not realize they do not drink enough water. Researchers studied 22 men. 10 of them were 23.7 years old on average (平均). 12 of them were 68.1 years old on average. The results showed that the older men drank much less water to stop them feeling thirsty.
What causes the problem The answer is still not known. Some scientists think that older people do not want to drink more because they do not want to wake up in the middle of the night to go to the bathroom.
However, water is not just for thirst, but also for health. We all need to remember that.
46．How much water should we drink every day according to the passage
A．Four glasses. B．Two glasses. C．Six glasses. D．At least eight glasses.
47．Why do we need to drink water
A．For thirst. B．For health. C．For fun. D．Both A and B．
48．Why do the old drink less water than the young
A．Because they don’t exercise. B．Because they don’t like drinking.
C．Because they don’t feel thirsty. D．We still don’t know the answer.

Hi, young scientists! Are you ready for some fun with science Doing science experiments is so interesting and it helps us question what we learn, think deeply, and create new ideas. Here is an easy and fun experiment about air pressure (压力) that you can do at home or school. Let’s have a try!
What do we need
①a glass
②a piece of cardboard (硬纸板)
③some clean water
How can we do it
Step One: Fill a glass with water.
Step Two: Put a piece of cardboard over the glass.
Step Three: Turn the glass over as quickly as possible.
Step Four: Hold the cardboard for a few seconds.
Step Five: Remove (移走) your hand from the underneath of the glass.
What will happen
The glass of water is upside down, but the water stays in the glass.
Why does this happen
This is because air pressure pushes the cardboard onto the glass. There is more air outside the glass than inside, so there is more air pressure outside than inside.
49．How many kinds of things do you need to do this experiment
A．Two. B．Three. C．Four. D．Five.
50．What is the second step of the experiment
A．Putting a piece of cardboard over the glass.
B．Turning the glass over as quickly as possible.
C．Holding the cardboard for a while.
D．Removing your hand from the underneath of the glass.
51．What makes the piece of cardboard onto the glass
A．The hand. B．Air pressure. C．Clear water. D．The glass.
52．What is the purpose of the text
A．To help students develop interest in science.
B．To let students know more about water facts.
C．To talk about the importance of saving water.
D．To call on people to take action to protect water.
C
For most visitors, no other tourist city is quite like Venice. They love its art museums, beautiful traditional buildings and squares. They also enjoy sitting in cafés and talking, or going to restaurants and tasting the delicious Italian food in the city. 53
Venice is a city on the water. 54 Canals (运河) run through the city like streets, so people usually travel around it by boat every day. For most visitors, their trips won’t be complete without a boat trip through the canals.
55 These years, it’s slowly going down into the water. When high tides (潮汐) come, the water from the ocean comes into the city. It happens more often, so Venice is lower than it was in the past. 56
Luckily, engineers are working on a project to save Venice. 57 It is difficult and expensive to do that. But if it works, Venice’s beautiful buildings will be safe, and the city will still be there for people to visit long into the future.
A．This is also destroying the old buildings in the city.
B．They’re putting 78 big gates to stop the water from coming in.
C．You can find over 117 islands and more than 400 bridges in it.
D．But what makes Venice a really special place is the water.
E．However, Venice is in danger because of its water.
F．Venice is famous throughout the world, and people also call it the “Floating City”.

【详解】句意：老师要求我们多学习关于水资源保护的知识。
考查非谓语动词用法。learn是动词原形；learning是现在分词；to learn是不定式；learned是过去分词。根据“asked us...more about water conservation”可知，此处考查ask sb. to do sth.（要求某人做某事）的固定搭配，因此应选不定式形式，故选C。
2．C
【详解】句意：云中的水太多了，很快就开始下雨了。
考查一般过去时和不可数名词。many许多，修饰可数名词；much许多，修饰不可数名词。根据“began”可知，此句是一般过去时，water是不可数名词。故选C。
3．B
【详解】句意：——我们现在离开吗？——别着急，我们还有一点点时间。

4．D
【详解】句意：—— 你的电话号码是多少？—— 是0532-86982896。
考查特殊疑问句。How many多少（用于可数名词）；How much多少（用于不可数名词）；Where哪里；What什么。根据答句“It’s 0532-86982896”可知，问句询问的是电话号码是什么。故选D。

【详解】句意：我们应该注意保护水资源。
考查非谓语动词。pay attention to“注意”，动词短语，to为介词，因此空处应用动名词形式作宾语。故选B。
9．A
【详解】句意：这艘船的发动机太旧了，无法为它提供动力使其前进。
考查动词词义辨析。power给……提供动力；push推；pull拉；lead带领，引导。后三个选项从动作方式上与 “驱动发动机使船前行” 不同，power作动词时符合该语境。故选A。

12． makes up
【详解】对照中英文可知，缺少“占”，用make up“构成，组成”，动词短语。描述事实用一般现在时，主语为不可数名词water，空处动词用三单形式。make的三单形式为makes。故填makes；up。

【详解】根据中英文对照可知，空处表示“把……还给……”，用短语return sth to.../give sth back to...。情态动词must后跟动词原形。故填return/give；to/back to。
20． look around
【详解】根据中英文对照可知，缺少“到处看看”，其英文表达为“look around”，“Why not + 动词原形”是一个常用的提建议的句型，意为“为什么不……呢”，其后需接动词原形，故填look；around。
