Ⅰ.阅读理解

A

The year is 2094. It has been announced that a comet (彗星) is heading towards the Earth. Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth.

On 17 July, a piece four kilometers wide enters the Earth’s atmosphere with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned.

Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won’t escape for long. Because of the explosions, the sun is hidden by clouds of dust, and temperatures around the world fall to almost zero. Crops are ruined. The sun won’t be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive.

Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then about 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out. Will we meet the same end?

语篇解读：文章主要描述了2094年如果一颗彗星的碎片撞向地球，人类可能面临终结。 1．What is mainly described in the passage? A．A historical discovery. B．An event of imagination. C．A research on space. D．A scientific adventure.

解析：选B 细节理解题。根据第一段的时间2094以及下文的内容可知，文章描述了人类

高中英语专题

在2094年可能会遭遇的灾难。这些事情只是一种想象而已。

2．When the first piece hits the South Atlantic, it causes ________. A．an earthquake B．damages to cities C．an Earth explosion D．huge waves

解析：选D 细节理解题。根据文章第二段中“Huge waves are created and spread outwards from the hole.”可知答案。

3．Why can’t the northern half of the earth escape for long? A．Because the land is covered with water.

B．Because the light and heat from the sun can not reach the earth. C．Because people there can not live at the temperature of zero. D．Because wars break out among countries.

解析：选B 推理判断题。文章第三段中提到，南半球的数以百万计的人已经死了，而北半球也逃脱不了这种噩运。因为太阳照不到地球，地球上的温度几乎降到了零度。庄稼遭到了破坏，食物缺乏导致战争的爆发。所以，一切的根源在于B项所提到的事情。

4．By giving the example of dinosaurs, the author tries to prove ________. A．animals could not live in the cold climate

B．what happened 65 million years ago was an invented story C．the human beings will die out in 2094

D．the Earth could be hit by other objects in space

解析：选D 推理判断题。根据最后一段中的“Could it really happen？”以及“Will we meet the same end？”两个问题的提出可知，作者是想通过举恐龙这一例子说明地球很有可能再次遭遇撞击。

B

The human brain contains 10 thousand million cells (细胞) and each of these may have a thousand connections. Such great numbers used to discourage us and cause us to stop thinking about the possibility of making a machine with humanlike ability, but now that we have grown

used to moving forward at such a speed we can be less sure. Quite soon, in only 10 or 20 years, perhaps, we will be able to build a machine as complex (复杂的) as the human brain, and if we can we will. It may then take us a long time to make it as intelligent as the human brain by properly programming it.

I think it is certain that in decades, not centuries, machines of silicon (硅) will arise to compete with their human ancestors. In a real sense they will be able to reproduce

themselves. Silicon will have ended carbon’s long control. And we will no longer be able to consider ourselves to be the finest intelligence in the world.

As the intelligence of robots increases and their cost goes down, we may achieve a lot with their help, first on the earth through their ability to complete any kind of work in harmful environments. In the end, deserts (沙漠) may turn into gardens. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the creation of a huge, man­made world in space, home to thousands or millions of people, will be within our power.

语篇解读：本文是一篇议论文。作者主要谈论了机器人可能给人类未来生活带来的改变。

5．In the author’s opinion, the human brain ________. A．is complex and intelligent B．is too complex to be reproduced C．may change a lot in 10 or 20 years D．will soon be replaced by machines

解析：选A 细节理解题。由第一段中的“as complex (复杂的) as the human brain”和“as intelligent as the human brain”可知，作者认为人类的大脑十分复杂而且非常聪明，故选A项。

6．The underlined word “carbon” in Paragraph 2 stands for ________. A．human beings B．an old machine C．an ocean animal D．intelligent robots

解析：选A 词义猜测题。由该段中的“machines of silicon (硅) will arise to compete with their human ancestors”可知，carbon在此是指代人类(碳基生命是以碳元素为有机物质基础的生物，地球上已知的生物，包括人类在内，大多数都是碳基生命)，故选A项。

7．In the last paragraph, the author mainly ________. A．talks about the intelligence of robots B．explains how to create a world in space C．describes what our future life might be D．shows his worry about the environmen

C

高中英语专题

These are some ideas that some people came up with about what the life will be like in the year 2500.

We will have established a base on the moon. School kids can take field trips to the moon weekly. We will have found cures (疗法) for AIDS and cancer. The war will have ended and peace flows freely through the land. Kids will learn more and be smarter than ever before! History will be the main subject at school. Cafeteria (自助餐厅) food will be delicious! You just walk up to a machine, stick out your tongue, and it will scan your taste buds (味蕾) to see what you want to eat.

— Kristen

Here I am in the wonderful year of 2500 and life is so easy. I work in a pet store and it is so hard! I have to wake up at midnight every day and fly my car to the store. It takes so long to get there. It takes me 20 seconds to get to the store in Mississippi from my home in Florida! At work, I have to push 5 buttons and then I go home. It takes 2 seconds and that is like forever.

— Morgan

In the year 2500, I think we will have invented cars that run on things we don’t need like garbage. Tail gas will smell like whatever you like such as chocolate. I also predict that buildings will be able to go into a different dimension (维) so your car won’t hit them. The cars in 2500 don’t fly, for we haven’t got that technology yet, but they can hover (盘旋) up to seven feet. These cars are made for speed!

— Carly

Instead of cars, we may have hovering devices that float around. We could also have electric cars instead of gas­powered cars. Food might be more healthy. What I believe is that the environment will change the most. The environmental changes will also determine many other changes. If more people try to help the environment, then perhaps in 2500 we will have more forests and wildlife. If people won’t help the environment, then we will have no forests and little wildlife left。

— Roberta

语篇解读：2500年的生活会是什么样子呢？人们对它展开了丰富的想象。 8．According to Kristen, what will happen in 2500? A．English will be the main subject at school. B．Students can go to the moon every week. C．Cafeteria will replace other restaurants.

高中英语专题

D．AIDS and cancer will disappear.

解析：选B 细节理解题。根据文章中克里斯滕所说的话“School kids can take field trips to the moon weekly.”可知B项为正确答案。

9．Morgan thinks his work in the pet store is ________. A．difficult B．meaningless C．important D．easy

解析：选D 推理判断题。文章中摩根对他工作的具体描述使用的是反语，他真实的意思是“这份工作太轻松了”。他的第一句话也是对该意思的提示，故选D项。

10．Who mainly tells the reader of the cars in 2500? A．Kristen. B．Morgan. C．Carly. D．Roberta.

解析：选C 细节理解题。根据文章中卡力所说的那段话可知，他主要谈到的是2500年的汽车，包括汽车的燃料、废气及功能等，故选C项。

11．Roberta thinks that in 2500 ________. A．the environment will have changed a lot B．there will be more wildlife and forests C．the environment will be seriously damaged D．cars will run on solar power and electricity

解析：选A 细节理解题。根据文章中罗伯塔所说的那段话可知，她所坚信的是环境一定会变化很大，或往好的方面变化，或往坏的方面变化。

Ⅱ.阅读七选五

How to be a good roommate

Roommate horror stories are pretty popular topics of conversation at school. Follow a few simple tips to ensure you’re not the awful roommate everyone’s talking about.

Respect each other

First and foremost, you need to respect your roommate.

•__1__ If your roommate is sleeping, keep the noise and light levels down. If your roommate is studying, don’t have loud conversations in the same room. If in doubt, ask yourself whether you would be annoyed if your roommate didn’t do the above things for you.

•Keep it clean. __2__ Hair in the shower or bath­rooms littered with magazines or dirty clothes. Respect means keeping your side of the room clean. And hopefully, if your roommate sees you keeping your side clean, they’ll be more likely to keep theirs clean.

•Keep your hands off their stuff. __3__ If you really need to borrow something of theirs, always ask before you do. If they say no, don’t get angry. Some people just don’t like other people using their stuff.

Set basic rules

You and your roommate should establish some basic rules. For instance, I really don’t like it when people have phone conversations in the room while I’m studying. __4__ I’d rather be writing my paper than listening to you tell your best friend about your weekend. So discuss that with your roommate. Make a compromise, but the tie should go to the person studying. Another example is to discuss cleaning duties. Dividing cleaning duties will make your room cleaner and it will help ease roommate tensions.__5__

A．It is amazing how people don’t understand what it means to be considerate. B．Taking out the trash and tidying the room are just a few things to consider. C．I have heard many horror stories about dirty roommates D．I’m not good at doing several things at the same time. E．Don’t use your roommate’s items without asking. F．Talk on the phone. G．Be considerate.

语篇解读：本文是一篇说明文。文章介绍了如何成为一个好室友。

1．选G 根据本段中建议大家在室友睡觉的时候降低音量、调暗灯光以及在室友学习时不要大声喧哗可以看出，作者建议大家“为他人着想，体贴他人”。

2．选C C项中的dirty roommates不仅符合本空后一句内容，也呼应Keep it clean的建议。

3．选E 本段建议大家不要动室友的东西，也就是说“未经允许，不要使用室友的物品”。 4．选D 作者在学习的时候不希望有人在旁边打电话是因为作者“不擅长同时做好几件事”。

5．选B B项中的Taking out the trash和tidying the room就是本空前的cleaning duties的例子。
