We don’t know how different our future will be in the future.We can only try to imagine it.

At first we think about human relationship.In the year 2050, we will use computers almost every day.We will be making new friends through the Internet—even our husbands or wives will be met in this way.It will be much faster and easier for us.On the other hand, our relationships with people won’t be as important as they are today—we will feel a little lonely.

Computers will also help us in many other activities in 2050.For example, they will be used by the children at school to make their learning easier.In addition, there will be much more other machines which will play a similar role as computers, like robots which will do the homework for us.

Spending holidays will also be completely different.Traveling to other planets or to the moon will be available for everyone.Means(方式) of transport will, of course, change, too.We will be using solar-powered cars, which will be much cleaner.

We could expect that the faster technological progress would lead to a more polluted environment.But it isn’t true.We will pay more attention to protecting the environment.And, scientists will probably find cures for many dangerous diseases, like cancer or AIDS.Therefore, our surroundings as well as health will be in better condition.

Although we can’t predict(預(yù)測) the exact changes which will be made in the world, we often think about them.We worry about our and our children’s future; we have expectations, hopes as well as fears.But I think we should be rather sanguine(樂觀的) about our future.We should be happy and believe good things will happen.

1.Why will people probably feel a little lonely in 2050?

A.Because the number of people will become much smaller．

B.Because there will be less face-to-face communication

C.Because people won’t like making friends with each other

D.Because people won’t communicate with each other much often．

2.According to the passage, which of the following will happen in 2050?

A.The relationship between people will be more important than today.

B.The way of spending holidays will be the same as that of today.

C.It won’t be difficult for people to travel to other planets.

D.Our environment will be much more polluted with a growing number of cars.

3.What does the passage mainly talk about?

A.How people will communicate in the year 2050.

B.What our life will be like in the year 2050.

C.How people will travel and spend their holidays in the year 2050.

D.What high technology will appear in the year 2050.

You are probably familiar with the saying：An apple a day keeps the doctor away.A recent research carried out by the Chinese University of Hong Kong may change the saying:

An apple a day may keep aging away.

The research chose fruit flies(果蠅), as they share many genes(基因)with humans.The fruit flies were either fed normally or had an apple extract(濃縮物) added to their diet.

It turned out that those fruit flies that were given apple extract lived about 55 days—five days longer than the flies that were normally fed.The research group also found it easier for the flies to walk，climb and move about as they aged.

According to the result, the researchers believed that the antioxidants(抗氧化劑) in the apple extract helped clean up dangerous chemicals(化學(xué)物質(zhì)) that cause illnesses，as well as aging.

In another study，researchers examined diets of thousands of women.They discovered that those who regularly ate apples were 20 percent less likely to suffer heart illnesses and stroke.

The apples’ genetic code(遺傳密碼) was discovered recently.It allows scientists to develop nicer and healthier fruits.Researchers are already using the information to grow a kind of apples full of antioxidants that can keep eyes and joints healthy and protect humans against heart illnesses and cancer.

Apples that kill the desire(欲望) to eat could also be produced, with the first “extra-healthy’’ apples on supermarket shelves within just four or five years.

The team that keeps studying apple DNA includes 100 scientists from five countries.Their research also suggests that around 65 million years ago, when dinosaurs began to die off the plant，which would finally become today’s apple tree, experienced a great genetic change.The number of many of its genes doubled.The extra genes allowed the apple to get used to worse conditions and go through a different development from peaches，strawberries and other related fruits.

1.Why were fruit flies used for the research?

A.Because they have a similar diet to humans.

B.Because they have a history as long as apples.

C.Because they share a lot of genes with humans.

D.Because they feed on nothing but apple extract.

2.What result did the researchers find out?

A.Apples produce chemicals that can change human genes.

B.Apples have antioxidants that kill chemicals that cause aging.

C.Apples are rich in vitamins that are needed in humans’ bodies.

D.Apples produce chemicals that make apples taste more delicious.

3.What can we infer(推斷)from the passage?

A.Eating apples may bring us more advantages than we might believe before.

B.People who have the habit of eating apples don’t need to see a doctor.

C.Apples that kill the desire to eat are already available in supermarkets now.

D.People will eat apples instead of peaches and strawberries from now on.

Language is a way to communicate with each other.We started to l 1. language when we were born.However, people are used to speaking their native language, so immigrants (移民) are having many problems between the first generation (第一代) and the second generation because they don’t have the s 2. native language.Also, the second generation is losing their identity (身份).Especially in America, there are many immigrants that came from different c 3. to succeed in the States.Because they suffer in lots of areas such as getting a j 4. and trying to speak English, they want their children to speak English, not only at school, but also at home in order to be more s 5. .Because of this situation, their children are losing their identity, and even more, they are ignoring (忽視) their p 6. who don’t speak good English.

I think most immigrants are trying to keep their native language in their new country, but this doesn’t help very much in getting a good job.My aunt t 7. Korean to her children not to help them succeed in the US; she did so, h 8. , to help them get a Korean identity.Though the second generation is born in the new country, they often get confused about their identity because they look different from o 9. .My cousins told me that when they visited Korea a few years ago, they felt different from other Koreans.

We must realize that language is important and v 10. for many reasons.Immigrants should make an effort not to be ignored by their children and to make their children understand their background by teaching them the parents’ language.
