1.A wind tunnel is used for testing planes or plane models.In a wind tunnel air is blown over a plane ora model placed in a test section.Wind tunnel test sections are different in size depending on airflow speed requirements.Some low-speed tunnels have test sections large enough for a complete small plane.In the very high speed tunnels used for space testing，however，the model may be as small as a pencil.There are two ways of feeding air to the test section.In the constant flow tunnel，airflow produced by electric fans is forced through the tunnel to the test section，then through another tunnel section back to the starting point for reuse.The other way involves storing high-pressure air in a box，sending it out by a controlling device to pass through the tunnel and test section into another box.This way is usually used for a very short period of high-speed airflow.Wind tunnels are usually used to test planes before they are flown.Problems in a plane carl be found when it meets the high-speed airflow in the tunnel.For example，if the wings are built so that they would weaken at high speeds，this fact can be discovered in the tunnel，thus saving many lives and millions of dollars.In a wind tunnel，scientists also find out how different planes will act at different speeds.They find out such things as how the air dives by the wing surfaces，how slowly a plane can fly before it starts to drop，and howfastit can climb.What can we learn from the passage?

5.California families are facing a rapidly mounting uphill battle to make enough money to provide basic household essentials, according to a new study conducted by the California Budget Project. 　　The research compiled by the Sacramento-based non-profit organization concluded an average two-parent family with one employed adult in California needs to make $51,177 a year, or $24.60 cents an hour, to pay for housing, transportation, food, utilities, child care, health coverage, taxes and other basic expenses. 　　The number grows significantly higher in the Bay Area, the state's most expensive region．A Bay Area family of four with two working adults living in rental housing needs a combined income of $79,946 to cover essential needs．That number is more than four times greater than the $19,157 income level recognized by the federal government as impoverished. 　　The study is the fourth semi-annual survey conducted by the California Budget Project since 1999． California Budget Project executive director Jean Ross said helping state officials and residents understand the numbers found in the report is crucial to moving families toward self-sufficiency. "How should we be targeting some of our programs and policies? How much do young people need to earn and what kind of a job should they be looking to train for if they want to have that salary that can support a family?" 　　CBP said the project was based on actual costs or generally accepted fair standard prices based on weighted averages found in ten California regions.[单选题] In the Bay Area, a family needs to earn __ the amount they do in other areas．

6.Passage ThreeAs recently as three decades ago,many Americans believed that using credit was an unwise anddangerous way to pay for what they bought.Some even thought that owing money to a store or acredit company was something to be ashamed of.Good citizens,they believed,always bought what they wanted with real money and they paid the full price immediately.Today,however,all that has changed.Credit,as some observers have noted,has become away of life in the United States.More and more Americans now are depending on those small piecesof plastic,credit cards,to pay for large purchases such as televisions,record players or furniture.Many people today would consider it unusual not to use a credit card to pay for a costly restaurant dinner,a hotel room or an airline trip.And there are some situations in which Americans must have credit cards.If they want the temporary use of a car,for example,they first must give the car rental company the number of their credit card.That number is considered a guarantee that they will returnthe car and pay for using it.Credit cards offer two major services to Americans.First of all,they are easier and safer tocarry than large amounts of money.Second,they permit people to borrow,to have the immediate pleasure of owning something,even if they do not have enough money to pay for it at the time.With credit cards people pay for goods or services at the end of each month instead of when they buy them.And when the time does come to pay,most credit cards offer people a choice.They can pay all of what they owe for the month or they can just pay usually between 5 and 10 percent of what they owe.46.What advantage can credit card holders have?

Passage One

Population tends to grow at an exponential( 指数的 )rate. This means that

they progressively double. As an example of this type of growth rate take one penny and double every day for one month. After the first week, you would have only 64 cent, but after the fourth week you would have over a million dollars.

This helps explain why the population has come on “all of a sudden ” took from he beginning of human 1ife to the year 1830 for the population of the earth to reach one billion. That repents( 缓慢进行 ) a time span of at least two million years. Then it took from 1830 to 1930 for world population to reach 2 billion. The next billion was added by 1960 only thirty years and in 1975 world population reached 4 billion which is another billion people in only fifteen years.

World population is increasing at a rate of 9, 000per hour, 220,000 per day and 80 million per year. This is not only due to higher birth rate, but to lower death rate as well. The number of births has not declined at the same rate as the number of deaths.

Some countries such as Columbia, Thailand, Morocco, Costa Rica and the Philippines are doubling their

population about every twenty-one years with a growth rate of 3.3 percent a year or more. The United States is

doubling its population about very eighty-seven years, with a rate of 0.8 percent per year. （81）Every time a population doubles, the country involved needs twice as much of everything, including hospitals, schools, resources, food and medicines to care for its people. It is easy to see that this is very difficult to achieve for the more rapidly growing countries.This passage chiefly discusses _____.

When you stretch out in the sun you can do one of the three things: you can use no sun tan oil, an ordinary sun tan oil; or Bergasol.

If you don't use any sun tan oil when you're in

the sun, you will burn surprisingly quickly. If you use an ordinary sun tan oil, you will protect your skin to a lesser or greater degree.How much protection depends on the "protection-factor number" on the bottle. Some oils block out so many of the sun's rays and you can stay in the sun all day without burning but you won't go very brown,either.

Bergasol will protect your skin like an ordinary

sun tan oil. It also has a tan accelerator that speeds up the rate at which the sun activates the skin cells that produce melanin(黑色素). It is melanin that gives the skin its brown colour. Bergasol enables you to go brown faster,am as the days pass the difference will become more obvious.Unfortunately, this special formulation isn't Cheap to prepare.So Bergasol is rather more expensive than ordinary sun tan oil. However, the price looks more attractive as you do.

Bergasoi It makes you go brown faster

Protection Many people imagine that "cover-up" means you don't get a tan. Nothing to show for your holiday.

Not so. With "cover-up", you can get brown if

you want to. The point of "cover-up" is to protect your skin from the harmful rays of the sun which,according to the experts ,make your skin look older.

That's what Solex Cover-up is all about--protection for your skin. It has a Sun Protection Factor 8,which makes it suitable for anyone. Find out how it works for you by consulting the Solex Sun Chart.

On sale wherever Solex is. With Solex Cover-up, you can tan as slowly as you like. As gently as you like. And with much less chance of peeling. Your tan will look better. Your skin will stay young longer.

Using 1ess energy around the home is easier than you might think，saving you money while

creating a heathier，more comfortable living space for you and your family. Changing a few old habits can make an impact on your energy bill， your comfort and the environment. Here are some handy tips to make your house more energy-efficient.

Lower the heat If your home has adjustable central heating，lowering the room temperature even slightly can make a difference. You may not feel it，but your wallet will. It is even more advisable to control

temperatures at different times of the day.

Hang clothes out to dryIf the weather allows it，head outside and dry your laundry on a clothesline. The sunlight will help eliminate bacteria and dust. While clothes dryers get the job done faster，they also use up energy.By hanging your clothes out you’ll be cutting greenhouse gases by about three kilograms per load.

Take advantage of natural light Installing large windows on the northern side of your house can help you make use of sunlight’s natural warmth. To stay cool indoors on hot summer days，install blinds(百叶窗) to block the heavy

sun.Put your desk near the window，then you don’t need a lamp in the daytime.

Wrap(裹)your pipes Be sure your hot—water pipes are properly wrapped.In an average home，heating water accounts for more than one—quarter of the energy bill.Why let warmth go to waste before it reaches you?

Choose the right size for appliances(家用电器)

When the time comes to replace appliances，select those that are both energy—efficient and of the appropriate size for your needs.Don’t buy bigger ones just because you can.What can be installed on the northern side of your house to make better use of natural light?

Most students choose “Homestay” accommodation when they study abroad：others select Homestay even if they are not on a study visit.Statistics show that it’s a form of accommodation gaining in popularity all the time.

But what is Homestay? And what makes it so popular?

Homestay means living with a family，or“host family”as we say.There are three ways of doing it：choose to learn English in a language school near to your Homestay location：have your English classes in the house with a member of the family who is a qualified teacher;

select not to have classes at all when you visit——a popular choice if you want to do the tourist thing for example.

Even in their busy summer period the organizations that arrange the Homestays will always try to place you with the most suitable host family to match your requirements.Placement( 安置)organizations think about location，interests，language level，eating requirements，allergies

(过敏)and other requests you may have.

Though prices vary according to your needs，good quality Homestay accommodation can be

relatively economical--and although you may be charged an extra amount of money if you want your Homestay in or near the city center.Even if you stay further out，you can expect your journey into the center not to exceed 30 minutes.

Not only does Homestay accommodation represent value for money， it also gives you an excellent opportunity to practice English with your host family.This is a very important extra for students who like to speak as much English as possible. But if you plan to learn English，why not have your English classes in your host family. There’s no better way to learn English than this—the perfect combination of learning and accommodation combined with the cultural experience !What can be inferred from the passage?

20.Passage TwoThere were many different cultures in the ancient world,but the two that had the most influence on European and American civilizations were the Greek and the Roman.Often these two cultures are lumped together in our minds,as if they were really exactly alike.But that is not the case.In many ways the Greeks and the Romans could not have been more different.The Greeks were truly democratic,often without a single leader but instead governed by a group of men chosen by the people.The Romans were semi-democratic.They had a governing Senate,but the political power was mostly or completely in the hands of a single emperor.Both cultures were great builders.But the construction interests of the two cultures were also different.The Greeks tended to be more artistic.Their buildings were well constructed and they were especially interested in temples,columns,and decorative forms.The Romans,on the other hand, were more engineers than artists.They concentrated their efforts on urban planning,well-functioning water pipes,and the best roads.Only in cooking and eating habits are the two cultures really similar.Both peoples ate very well indeed:lots of fish,fresh vegetables and fruits,healthy meals,holding at the same time longdiscussions and tasting excellent wines.In fact,it would probably be fair to say that they both loved life in their warm,sea-orientedclimates,and they both lived a full life.40.What is the first paragraph about?
