For hundreds of years, scientists have been trying to answer what things have an effect on people’s emotions (情感). How you feel is controlled by many things. Your emotions can be affected by your personality, by the actions of others and by events around you. Perhaps you don’t know your emotions can be influenced by the weather as well.
People often say they feel good when the sun is shining and sad when it is cloudy. In fact, sunlight makes us feel good. When sunlight hits our skins, our bodies produce a vitamin. Vitamins are natural chemicals (化学物质) which we all need to stay healthy. Sunlight helps our bodies produce vitamin D. Vitamin D helps our bodies make a special chemical. This special chemical affects our brains (大脑) and makes us feel happy. For example, there are long, dark winters of little sunlight in Sweden and Norway, so many people in these countries often feel sad. Without much sunlight, their bodies produce less vitamin D. Without enough vitamin D, their bodies make less of this special chemical which makes them feel good. To help the people in these countries feel better, special “sunrooms” with artificial (人造的) lights have been built. People can go there and get “sunlight” for an hour or two!
The weather can also affect people’s emotions in other ways. Hot weather can make people angry because people feel uncomfortable when they are hot. In the same way, rain can make people angry because being wet can be unpleasant. As you can see, the weather can have an effect on the chemicals which control our brains. Through these ways, the weather can influence our emotions. Sadly, while the weather can change us, we can hardly change the weather.
Which of the following is NOT mentioned as a factor (因素) that can affect one’s emotions?

A．Weather.	B．Actions of others.
C．Personality.	D．Age.

Which of the following is true about vitamin D according to the passage?

A．It is a kind of artificial chemical.

B．It makes us worried by affecting our brains.

What can we infer (推断) from the passage?

A．We feel good when we are in the bright cool weather.

B．We will be happy when we are caught in the rain.

C．All people in Norway and Sweden feel sad in winter.

D．The more vitamin D you have, the happier you’ll be.

More and more people think it necessary to study in an English-speaking country and it didn’t take long at all for me to decide to come and study in UK.
I have been used to school life since I came here two months ago, and I am starting to enjoy most of my time in here. School starts at 9 o’clock every morning, and every Monday, Wednesday and Friday we have long days, in which we have 9 lessons and school finishes at 4 o’clock. Every Tuesday, Thursday and Saturday we have short days, in which we have only 6 lessons and finish at 1 o’clock. After lessons, we have 2 hours of activity time, when you can choose from a number of activities, including many sports, such as rugby(英式橄榄球) , football, basketball and tennis.

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(果蝇), as they share many genes(基因)with humans. The fruit flies were either fed normally or had an apple extract(浓缩物) 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(抗氧化剂) in the apple extract helped clean up dangerous chemicals(化学物质) 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(遗传密码) 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.
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.

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.

What happened to apples around 65 million years ago according to the research?

A．Their genes stopped their development as the environment got worse.

B．Their genes became twice in number but they finally died off like dinosaurs.

C．They experienced a great genetic change making them get used to worse conditions.

D．They went through a similar development to peaches, strawberries and other related fruits.

What can we infer(推断)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.

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(预测) 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(乐观的) about our future. We should be happy and believe good things will happen.
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．

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.

What does the passage mainly talk about?

A．How people will communicate in the year 2050.
