Hundreds of years ago, life was much harder than it is today. People didn’t have modern machines. There was no modern medicine, either. Life today has brought new problems. One of the biggest is pollution （污染）. Water pollution has made our rivers and lakes dirty. It kills our fish and polluted our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It’s bad to all living things in the world. Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt over a city. This kind of quilt is called smog（煙霧）.
Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away, they mustn’t blow dirty smoke into the air. We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.
Rules are not enough. Every person must help to fight pollution.

A city in California has got some new buses. They cost $490,000 each. The new buses are different from the old ones. These new buses are better for the environment. They are called hybrid (混合動力的) buses. They run on diesel (柴油的) and electric power. This will help keep the air cleaner.
The man drove the new bus on Wednesday and noticed a difference right away. “I get to have clean air for a change”, said driver Melvin Day. “I’m smelling diesel all day long when I drive the old ones.”

Being safe in your everyday life needs knowledge. If you remember the following information, your life will be much safer.
Always notice the environment around you. You shouldn’t walk alone outside. Make sure where the public phones are. If anything dangerous happens, you can find them easily.
Your bag should be carried towards the front of your body instead of putting it on your back. When a bus is full of people, it is easy enough for a thief to take away the things in the bag on your back.
If you are followed by someone you don’t know, cross the street and go to the other way, let the person understand that you know he or she is after you. Next, don’t go home at once. You are safer in the street than you are alone in your home or in a lift (電梯).
If you have to take a bus to a place far away, try to get to the stop a few minutes earlier before the bus leaves. This stops other people from studying you. On the bus, don’t sit alone. Sit behind the driver or with other people. Don’t sleep.
小題1: Which of the following is NOT safe when you are out?

A．Go home alone late at night.

When do you think of a forest, what do you see? Just trees Or do you see many other things, such as singing birds, colorful plants and wild flowers?
The forest is a whole world of its own. It is full of many different living things (生物). But even thoughthey are all different, they have one thing in common: they all need each other in order to live on.
The trees feed the forest "people" by making food in their leaves; by using sunlight to join water and minerals(礦物) from the soil and air. Their deep network of roots Joins the soil together and stops it from dying out, making it possible for living things to live in it. Human beings (人類) are like the living things in the forest. We need one another in order to live. We need the farmers to grow our food, railroad and truck drivers to bring it to our shops and clerks (售貨員) to sell it to us. We need people to prepare our food and
cook it and others to take our waste things away. Then, of course, we need doctors, nurses, government leaders, mailmen, telephone operators, and many others. We also need other human beings in another way.
We need people for friendship, to talk over our problems, exchange ideas. Think how lonely and unhappy you would be if you lived all alone.
Life is a matter of giving and taking. We need to help other people as much as we need other people to help us. Think what a good feeling you have when you have done something for someone else. You know, being a volunteer is so great!
根據(jù)短文內(nèi)容，判斷下列句子正誤。正確的用“A”表示，不正確的用“B”表示。
小題1:According to the text, different things live on the soil and air.
小題2:The water and minerals join from the soil and air by using sunlight.
小題3:According to the writer, human beings need only farmers.
小題4:When I have done something for someone else, I feel happy.
小題5: According to the passage, everyone needs friends.

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(化學(xué)物質(zhì))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(大腦)and makes us feel happy.For example, there are long, dark winters of little sunlight in Sweden and Norway,so many peple 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.
小題1: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.

小題2: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.

C．It is needed by us all to keep fit.

D．It is in the sunlight.

小題3:What can we infer (推斷) 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.

小題4:What may be the best title for this passage?
A. Why Do We Feel Sad?
B. The Weather Influences People’s Emotions.
C. People Need More Vitamin D.
D. We Can Hardly Change the Weather.
