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.

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.
【小题4】What may be the best title for this passage?

Before you hit ‘Enter’ on MSN, read this
It is often said that the language we use online is less formal than that we use in a letter, or in direct speech sometimes. This is true, but it can also make us in trouble sometimes.
The thing about online communication is that you have no idea what the person who is reading your messages is feeling. For this reason, it is always a good idea to be polite and cautious when writing e-mails or messages to your friends.
Chinese can be a direct language, but in English, people often talk about a subject in another way. So instead of saying “Please meet me here” or “Do this for me now”, English speakers usually go for indirect phrases like “Would it be possible”, “if you have time” or “It would mean a lot to me if…”
If you have a close friend, you may still run into trouble because of your jokes. If you have asked someone to do something and they need a bit more time, you might joke with him: “What? You still haven’t done it yet? What’s wrong with you?” While this seems funny to you, your friend may feel unhappy.
If you have foreign friends in different countries, the time difference can also be a factor. While you are waking up for class on Friday morning, they may be having a party on Friday night. You will be serious and they will, probably, be excited. So don’t be angry if they seem not to care about you. Just try to message them at the proper time.
【小题1】 According to the passage, we learn that our letters are more ______ than the e-mails.

A.formal B.direct
C.different D.funny
【小题2】 As a language, Chinese is ______, but English is not.
A.polite B.rude
C.direct D.formal
【小题3】 Why should we be polite and cautious while chatting online?
A.Because we mustn’t play jokes online.
B.Because our friends are easy to be angry.
C.Because it can help us avoid lots of troubles.
D.Because we can’t see our friends online.
【小题4】 According to the passage, which of the following is right?
A.It is OK to connect your friend by MSN anytime.
B.Using the proper way to chat online is necessary.
C.Don’t ask your friend to do something for you by MSN.
D.Never play jokes with your friends.

The San Diego Zoo has been a lovely home for giant pandas since two of the black-and-white bears came to visit in 1987. This week there was snow in San Diego—well, at least for a lucky group of giant pandas.
Over 15 tons of snow was blown into the San Diego Zoo's panda area on Tuesday morning to give the endangered bears a chance to play. They would experience the snow just like living in their natural habitat.
The snow day was a first for Xiao Liwu whose name means "Little Gift." He was the sixth baby panda born to Bai Yun. Xiao Liwu was jumping on Mom, playing with her and getting used to being thrown in the snow by mama bear. Jennifer Becerra, San Diego Zoo keeper said, "He was really enjoying the snow and running around. I've never seen him so happy."
All the San Diego Zoo’s giant pandas are from China, as part of a long-term captive breeding(人工养殖) program. Four of Xiao Liwu's brothers have already been moved from California to China.
Today there are 44 giant pandas living in zoos outside of China, where the bears' only natural home is. As just 1,600 pandas are thought to be left in the wild, researchers insist that captive breeding is an important way to study and protect the endangered pandas. Not only because of the habitat loss from human activities and low reproductive rates(繁殖率), giant pandas' survival is also affected by climate change. A study showed that global warming could kill much of the bears' main food, bamboo, over the next century.
【小题1】Why was the snow blown into the San Diego Zoo's panda area?

A.To stop the bamboos from dying.
B.To give the pandas a chance to play.
C.To help the pandas live in their natural habitat.
D.To make Xiao Liwu happy.
【小题2】What’s the relationship between Bai Yun and Xiao Liwu?
A.Wife and husband.
B.Father and daughter.
C.Sister and brother.
D.Mother and son.
【小题3】What is NOT the factor that influences the giant pandas' number?
A.The loss of habitat.
B.Low reproductive rates.
C.Human research.
D.Climate change.
【小题4】Which of the following is the best title of this passage?
A.Giant pandas in San Diego Zoo
B.Giant pandas in danger
C.Xiao Liwu’s happy time
D.How to protect giant pandas
【小题5】Which of the following is true according to the passage?
A.Captive breeding is the most useful way to protect giant pandas.
B.More than 44 giant pandas live in zoos outside of China now.
C.China is the only natural home of giant pandas.
