Ⅰ.阅读理解
Life in 2060
Let us suppose it is now about A. D．2060.Let's make believe it is about fifty years from now.Of course, things have changed and life is very different.
Voyages to the moon are being made every day.It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe.At a number of scenic spots on the moon, many hotels have been built.The hotels are air conditioned naturally.In order that everyone can enjoy the beautiful scenery on the moon, every room has at least one picture window.Everything imaginable is provided for entertainment (娱乐) of young and old.
What are people eating now People are still eating food.They haven't yet started to take on heir (继承) supply of energy directly as electrical current or as nuclear power.They may some day.But many foods now come in pill form, and the food that goes into the pill continues to come mainly from green plants.
Since there are several times as many people in the world today as there were a hundred years ago, most of our planet's surface has to be filled.The deserts are irrigated with water and crops are no longer destroyed by pests.The harvest is always good.
Farming, of course, is very highly developed.Very few people have to work on the farm.It is possible to run the farm by just pushing a few buttons now and then.
People are now largely vegetarians (素食者). You see, as the number of people increases, the number of animals decreases.Therefore, the people have to be vegetarians and we are healthier both in our bodies and in our minds, and we know the causes and cure of disease and pain, and it is possible to get rid of diseases.No one has to be ill any more.
Such would be our life in 2060.

4 Tips for Surviving Finals Week
Even after months of hard work, your success or failure in a college class can depend on a single, heavily weighted assignment — the final. There are a number of ways to improve your performance during the finals week. Here are four to try：
·__1__
The finals week is so busy that you may not get time to learn new concepts. Therefore, the best thing to do is just to revise concepts before the day of your exam. No need to stress out and learn new things. __2__
·Get some sleep.
There are so many places on campus (校园) that open 24 hours — like the library, dining hall, etc. They encourage you to stay over there and study until late at night. __3__ If you stay up late, there are chances you may not wake up on time for your exam or you may even fall asleep during the exam. Staying up late may also affect your health, so try not to stay up late during the finals week.
·Do some exercise.
__4__ Regular, sweaty exercise helps us think better. An hour of active exercise per day will allow you to focus better in school and while studying.
·Take some time for yourself.
You may be so busy with studies in the finals week that you may not get enough time for yourself. __5__ It is suggested that you take at least 30 minutes out of your busy routine and spend some time on yourself. Listen to your favorite music or watch the TV shows you like.
A．It's only revision time.
B．Go to a peaceful place nearby.
C．But, this is one of the most terrible things.
D．One more thing to consider is your health.
E．Learning them at the last moment will just make you nervous.
F．You may be so stressed out that you can't even sleep well at night.
G．Exercise during the finals week is an effective way to increase your memory.
语篇解读：本文是一篇说明文。文章就如何度过期末考试周提出了几条建议。
1．选A 根据本空后面的“The finals week is so busy that you may not get time to learn new concepts”和“the best thing to do is just to revise concepts”可知，A项“这段时间只用于复习”符合语境。
2．选E 根据本空前面的“learn new things”可以锁定E项中的Learning them。代入后，“在最后时刻学习新知识只会使你紧张”符合语境。
3．选C 空前的“They encourage you to stay over there and study until late at night”和空后的“If you stay up late ...even fall asleep during the exam”之间是转折关系，故C项“但这是最糟糕的事情之一”符合语境，在文中起承上启下的作用。
4．选G 根据本空前面的小标题Do some exercise 可以锁定G项中的Exercise。代入后，“在期末考试周锻炼是一种有效提高你的记忆力的方法”符合语境。
5．选F 根据本空前面的“You may be so busy ... that”可以锁定F项中的“You may be so stressed out that ...”。代入后，“你可能会很紧张以至于晚上睡不好”符合语境。

With the development of science and technology, unmanned automobiles and aircrafts have been developed and put into use. What will our transportation will be like in 10 years
I'm sure that unmanned automobiles will be used widely all over the world. And people will do many meaningful things in the car instead of driving. What's more, disabled persons and children can operate a car by themselves.
Because unmanned automobiles are controlled by computers, cars on the street will be well ordered. Thus some traffic problems such as the traffic jam and accidents will be solved easily. Both people and cars will be much safer on the street then.
I'm looking forward to the wonderful life in the future.

参考范文：
With the development of science and technology, unmanned automobiles and aircrafts have been developed and put into use. What will our transportation will be like in 10 years
I'm sure that unmanned automobiles will be used widely all over the world. And people will do many meaningful things in the car instead of driving. What's more, disabled persons and children can operate a car by themselves.
Because unmanned automobiles are controlled by computers, cars on the street will be well ordered. Thus some traffic problems such as the traffic jam and accidents will be solved easily. Both people and cars will be much safer on the street then.
I'm looking forward to the wonderful life in the future.
