20.72.D.It makes us wonder…if scientists can send a man to the moon,why can't they find a cure for the common cold?The answer is easy.There are actually hundreds of kinds of cold viruses out there.You never know which one you will get,so there isn't a cure for each one.
 73.A.Blood rushes to your nose and cause a block in it.You feel terrible because you can't breathe well,but your body is actually eating the virus.Your temperature goes up and you get a fever,but the heat of your body is killing the virus.You also have a runny nose to stop the virus from getting into your cells.You may feel very uncomfortable,but actually your wonderful body is doing everything it can to kill the cold.
74.E.In the United States and some other countries,for example,people might eat chicken soup to make themselves feel better.Some people take hot baths and drink warm liquids.Other people take medicine to stop various symptoms (癥狀) of colds.
75.C.The virus stays in you longer because your body doesn't have a way to fight it and kill it.Bodies can do an amazing job on their own.There is a joke,however,on taking medicine when you have a cold.It goes like this:
It takes about one week to get over a cold if you don't take medicine,but it takes only seven days to get over a cold if you take medicine.

A.When a virus attacks your body,your body works hard to get rid of it.
B.American people never take colds seriously
C.There is one interesting thing to note-some scientists say taking medicines when you have a cold is actually bad for you.
D.It is easy for many people to catch a cold in the springtime or fall.
E.Different people do different things to deal with colds.
F.You can't get over a cold unless you take some medicine.

We can't be happy forever,so learning how to face difficulities is important.Some people feel upset when they meet difficulities,and they don't want to try to let their dreams come ture anymore.They just want to find a place and stay at there for a long time.So they won't have a great success in the end.But others are different,some people don't think difficulities are troubles,they believe"Difficulities is the mother of the success''and"Believe in myself and I will win'',they are confident and breave,and they choose to face the difficulities with a smile.They try their best to solve their problems and if they don't feel well,they'll talk to their friends or family members,so that they can be happier and more confident.And they don't mind what others say about them,they can always find a good way for themselves to relax.

15.(36)FHalf a minute?A few seconds?
Google engineers have discovered that even 400milliseconds-as short as the blink of an eye-is too long for most Internet users.
A millisecond is one thousandth of a second.People hardly notice such a small time difference,but it does cause them to stop searching,reported The New York Times.
Nowadays,millions of smart-phones and computers are constantly gathering and sending out information.(37)B you can get digital"traffic jams".Meanwhile,users are expecting faster and faster service.
Google found that if one website is 250milliseconds slower than another website,then people will visit it  less often.(38)E Google said people do expect different things from different websites because they realize not all loading times are the same.For example,a person will be more patient waiting for a video clip to load than for a search result.
Even so,four out of five online users will click away if a video takes too long to load.This makes"difficult for video websites to choose between the quality of pictures and fast loading times.
Pursuing a higher speed has always been part of the history of the Internet.
In the 1990s,when the World Wide Web first started to become popular,(39)G people  called it the"World Wide Wait".But engineers managed to fight the problem with new inventions.They laid a lot of fiber optic cables for high-speed transmissions,they improved software so it would work more smoothly; they placed computer servers all around the world to be nearer to users; all this increased speed.
Nowadays we can enjoy much faster Internet.(40)C But they will need to keep fighting to keep up with the developing demands of internet users.

A.internet is becoming faster and faster.
B.With so many people downloading maps,sports videos,news and restaurant recommendations,
C.Major search engines such as Google and Microsoft's Bing usually find search results
in less than a second.
D.We can not expect a faster speed about the internet.
E.This is why technology companies are now competing to be the fastest.
F.How long are you willing to wait for a webpage to open before you start to lose your

A.Necessity for developing adult education
B.Early days of adult education
C.Ways of receiving adult education
D.Growth of adult education
E.Institutions of adult education
F.Functions of adult education
(61)F
Voluntary learning in organized courses by mature men and women is called adult education.Such education is offered to make people able to enlarge and interpret their experience as adults.Adults may want to study something which they missed in earlier schooling,get new skills or job training,find out about new technological developments,seek better self-understanding,or develop new talents and skills.
(62)C
This kind of education may be in the form of self-study with proper guidance through the use of libraries,correspondence courses,or broadcasting.It may also be acquired collectively in schools and colleges,study groups,workshops,clubs,and professional associations.
(63)A
Modern adult education for large numbers of people started in the 18th and 19th centuries with the rise of the Industrial Revolution.Great economic and social changes were taking place:people were moving from rural areas to cities; new types of work were being created in an expanding factory system.These and other factors produced a need for further education and re-education of adults.
(64)B
The earliest programs of organized adult education arose in Great Britain in the 1790s,with the founding of an adult school in Nottingham and a mechanics'institute in Glasgow.The earliest adult education institution in the United States was founded by Benjamin Franklin and some friends in Philadelphia in 1727.
(65)D
People recognize that continued learning is necessary for most forms of employment today.For example,parts of the adult population in many countries find it necessary to take part in retraining programs at work or even to learn completely new jobs.Adult education programs are springing up constantly to meet these and other needs.

9.Ten years ago,I used to be very fit.(36)C I used to play tennis a lot and go for long walks.In those days,I didn't earn very much.I had a job in an office.It wasn't a very good job but I had a lot of time to do the things I enjoyed doing.(37)A The pay was better,but the hours were a lot longer.I bought a car and drove to work every day.I began to take people out to lunch.And I began to put on weight,too.I stopped playing tennis and going for long walks at weekends because I just didn't have any time for things like that any more.
There's a lot of stress (壓力) in my job.Perhaps that's why I started drinking more than I used to.For example,I used to have only half a glass of whisky when I got home,but then I started filling my glass to the top.Then I had another glass,and then another.(38)E I never used to smoke at all.
Two months ago,I had a heart attack.At first I just couldn't believe it."I'm too young."I said.Luckily it wasn't very serious.I was in hospital a few days and they did a lot of tests.(39)G He also advised me to work less and get more exercise.But I just haven't any time!(40)B
Sometimes I wonder if I should get another job.Perhaps I could do something like I used to do.But if I do that,I won't earn as much.I have a family to support.I have to think of them,too.I just don't know what I should do.What do you think?
A.Then,about eight years ago,I got a much better job.
B.My job takes everything out of me!
C.I rode a bike to work and I got a lot of exercise at weekends.

10.A student's life is never easy.(36)G A lot of preparations are needed so you can be sure to go back home with a diploma and a bright future waiting for you.The following are some basic things you need to do before even seizing that passport and boarding on the plane.
●Knowing the country.
You shouldn't bother researching the country's hottest tourist spots or historical places.You won't go there as a tourist,but as a student.It'll be helpful to read the most important points in their history and to read up on their culture.(37)C You surely don't want to face legal problems,especially if you're away from home.
●Studying their language.
Don't expect that you can graduate abroad without knowing even the basics of the language.Before leaving your home country,take online lessons to at least master some of their words and sentences.(38)D  Doing this will also prepare you in communicating with those who can't speak English.
●(39)B
Check the conversion(兌換)of your money to their local currency,set up your bank account so you can use it there,get an insurance,and find an apartment.The Internet or your intended school will be very helpful in finding an apartment and helping you understand local currency.
Remember,you're not only carrying your own reputation but your country's reputation as well.If you act foolishly,people there might think that all of your country men are foolish as well.(40)E.

A.Packing your clothes.
B.Preparing for other needs.
C.Most importantly,read about their laws.
D.This will be useful in living and studying there.
E.That would surely be a very bad start for your study abroad program.
F.Going with their trends will keep it from being too obvious that you're a foreigner.
G.And it is even more difficult if you will have to complete your study in a foreign land.
