試題分析：現(xiàn)在衛(wèi)星正在幫助人們預(yù)測天氣。衛(wèi)星給大氣層拍照，因為這是天氣形成的地方。這樣在氣象站的科學(xué)家就可以看到世界任何地點的天氣和告訴人們天氣將如何變化。今天，在 60 個國家的近500個氣象站可以接收衛(wèi)星圖片。當(dāng)他們收到新的圖片時，他們會比較之前的那些圖片。這就是天氣預(yù)報，現(xiàn)在他們能很好地預(yù)測未來 3 或 5 天的天氣狀況。而過去他們可以預(yù)測約 24 或 48 小時的天氣。
小題1: 考查上下文的理解能力。上文的意思是：現(xiàn)在衛(wèi)星正在幫助人們預(yù)測天氣。所以這里應(yīng)該說原因：他們在空中，可以到達世界上任何一個地方。故選D前后相符。
小題2:考查上下文的理解能力。上文的意思是：衛(wèi)星給大氣層拍照，因為這是天氣形成的地方。下文說：這樣在那兒的科學(xué)家就可以看到世界任何地點的天氣和告訴人們天氣將如何變化。所以這里應(yīng)該說：它們將這些照片發(fā)送到氣象站。故選B前后相符。
小題3:考查上下文的理解能力。上文的意思是：當(dāng)他們收到新的衛(wèi)星圖片時，他們會比較之前的那些圖片。所以這里應(yīng)該是：也許他們可能會發(fā)現(xiàn)在過去的幾小時里云層變化了。故選E前后相符。
小題4:考查上下文的理解能力。上文的意思是：這可能就意味著天氣預(yù)報，。所以這里應(yīng)該是：他們可以告訴人們云層的變化。故選C前后相符。
小題5:考查上下文的理解能力。最后一段的意思是第一句話：所以氣象衛(wèi)星對于在氣象站的科學(xué)家有很大的幫助。后面說：現(xiàn)在他們能很好地預(yù)測未來 3 或 5 天的天氣狀況。所以這里說：過去他們只可以預(yù)測約 24 或 48 小時的天氣。故選A前后對比。

In a US study, researchers measured (測量) the happiness of 4739 people over 20 years. The study found that a person’s happiness depends on the happiness of people he connects with. Surprisingly, it also found that happiness spreads not only between direct friends, but also among friends of your friends’ friends! And those good feelings seem to have the greatest influence among friends of the same sex (性別).
“People with more good friends are less likely to develop depression (情緒低落) and worry,” says Dr. Toupey Luft. “Though you can’t choose your family or workmates, you do have control over friendships.” With a little effort, you can add more positive (正面的,積極的) relationships to your social circle. Here’re the suggestions:
“Nobody is all positive or all negative,” says Luft. “But there are people you may feel more positive. Use that as your way to check people and keep records.” When spending time with others, pay attention to your feeling. Are you feeling tired and unhappy？To help you keep records, Luft suggests taking a moment when you get home to write down what your feeling is when around them.
While it’s great to gather with positive friends, it’s also good to stay with others in the same life situations. “But if you’re all just complaining (抱怨) and nothing is changing, it’s not healthy,” says Luft. Are your friends negative, or are you doing most of the complaining? Considering the answers to these questions can help you decide if you want to stand in front of them. Or you could let the relationship disappear slowly.
Sometimes your hobbies can lead to true friendships. Check out newspapers and websites to find a group or class for something you enjoy. These friends can always be there for you and can care each other through difficulties, illness and death.
Not into groups? Look for individual (個人的) communication instead. Luft says, “Set small goals, such as having coffee with one new person, and develop friendship according to a plan. If someone suggests going for lunch sometime, set a date.”
“If you’re feeling disappointed (失望) with a friend, try talking about what you both need,” says Luft. For example, tell her what you want during hard times in your lives. While your friend may need to be left alone, you may want caring phone calls. With some friends you laugh and have fun together at the movies—and that can be enough. With others, you pay attention to your deep connection.
小題1:What does your happiness depend on, according to the passage?
A．How people you connect with feel.
B．How many friends you have.
C．What situation you are in now.
D．What kind of friends you have.
小題2:What does the first suggestion want us to do?
A．To measure our happiness.
B．To check people around.
C．To join a group for hobbies.
D．To leave negative friends.
小題3:Which of the following is true?
A．We often have many friends during good times but few during hard times.
B．It’s necessary to complain about something but not right to do so for long.
C．Joining a group can bring better friendship than making individual friends.
D．All the suggestions tell us to add positive relationship to our social circle.
小題4:The underlined sentence in the last paragraph means that ______.
A．when your friend is sad, you should call her up
B．when your friend leaves you, you need comfort
C．friends’ needs may be quite different sometimes
D．people may behave differently during hard times

For a long time being happy was considered something that just happened, and there was nothing special about it. Now we know that getting along with other people is something that we can work at. It is possible to act in such a way that other people will like us better. One way is being unselfish, not wanting everything from our friends. Another way is to look for good points, not bad points in other people. It is surprising how successful this treasure hunt can be.
You do not have to be spineless (優(yōu)柔寡斷的) in order to be popular. In fact, you will be liked or loved if you are not afraid to stand up for your rights (正當(dāng)行為). But do it politely and pleasantly. Being friendly and polite to your group, to other people and to strangers and especially to those who do not look important or do not interest you is one way to develop a good character.
You cannot expect to be perfect, and you must learn not to be unhappy when you make mistakes. Everyone makes mistakes, and no one is to be blamed if he does not refuse to learn from them. Many young people become discouraged (灰心喪氣的) when they know in themselves qualities that they do not like—selfishness, laziness, and other unpleasant qualities. Just remember that we all have some of these faults (缺點) and have to fight against them.
At the same time, it is important to remember that while you are probably no worse than others, the best way to be happy is to think yourself above other people. When something is wrong, it is good sense to try to make it right. Perhaps you do not like a teacher or a classmate. Try to see why, and look at yourself, too, to be sure that you are not doing anything to make that person dislike you. Some day, things may turn out all right when you have to learn to get along the best with the situation, without thinking too much about it. Worrying never helps in a situation you cannot change.
小題1:One of the two ways the writer suggests for us to get along with others is to __________.
A．work hard at everything we do
B．enjoy the best share of everything
C．look for treasure in order to be successful
D．pay more attention to their strong points
小題2:If a person wants to be popular, he or she has to __________.
A．be polite and friendly
B．give up some rights
C．get away arguing with other people
D．be ready to change his or her character
小題3:There is no person but someone should be blamed if he or she __________.
A．is modest and generous
B．is selfish and lazy
C．does not draw a lesson from his or her own fault
D．is very happy with unpleasant quality
小題4:The purpose for the writer to write the passage is to __________.
A．train you to be perfect
B．show you the way to be happy
C．tell you how to act when you dislike a person
D．teach you how to be popular among your friends
