12．Itis/was suggested（suggest） that the old computers should be replaced with new ones．

分析 有人建議：將舊電腦換成新的．

解答 答案：is/was suggested
根據(jù)that從句"should be replaced"使用了虛擬語(yǔ)氣可知，句中的suggest意為：建議；故本題考查的應(yīng)是固定句型"It is/was suggested that有人提議；根據(jù)建議"的用法；由于本句沒(méi)有時(shí)間狀語(yǔ)，故可以用一般現(xiàn)在時(shí)或一般過(guò)去時(shí)；故答案為：is/was suggested．

點(diǎn)評(píng) 做本題時(shí)，應(yīng)結(jié)合句意，并從語(yǔ)法分析的角度去判斷句中所填單詞的形式；另外，在平時(shí)的學(xué)習(xí)中，應(yīng)熟練掌握所學(xué)到的詞匯以及各類(lèi)詞法，句法等語(yǔ)法知識(shí)．

15．The Ramayana tells the story of a battle between the Hindu （印度教的） god Vishnu and a demon （魔鬼） called Ravana．None of the gods could fight Ravana because of a promise they had foolishly made earlier．So Vishnu decided to be reborn as a man，and then he would be able to fight Ravana．
So Vishnu was born as the prince Rama．Rama was supposed to be king when his father died，but at the last minute his father decided to make his brother king instead．Rama and his other brother Lakshmana and Rama's wife Sita went away to live a simple life in the forest，where the demon Ravana's sister fell in love with Rama and tried to get Rama to leave Sita．When Rama said no，Ravana's sister attacked him，but Rama and his brother Lakshmana fought her off．
The demon went back to her brother Ravana on the island of Lanka and complained to him that Rama had attacked her．Also，Ravana's sister told him how beautiful Rama's wife Sita was．So he went to the forest to see for himself．
When Ravana got to the forest，he found itwas true．So he took Sita back to Lanka．Sita was very sad there and missed Rama very much．
Rama and his brother Lakshmana needed help to rescue Sita，so they went to see the king of the monkeys，Hanuman，who had the magic power to make himself bigger or smaller．Hanuman found Sita on the island of Lanka and told her that Rama was coming to save her．Sita was very happy，but then the demon Ravana caught Hanuman and set his tail on fire!In the end，however，Hanuman escaped and set fire to the whole island of Lanka．
Hanuman went back to the forest and got Rama and Lakshmana，and they all went together with the whole monkey army to attack the island of Lanka．The monkeys made a bridge over to the island．There was a terrible battle，but finally Rama killed the demon Ravana．

7．Rising levels of carbon dioxide in the atmosphere are a major cause of climate change，and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life．
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades．
"We've been going to the same spot in the Pacific Ocean，and we try and characterize long-term change in the open ocean environment．And one of the key things that we measure is CO2 levels．And we've b een able to record this increasing quantity of atmospheric CO2 into the ocean．"
Scientists expected that as atmospheric CO2 increased，more and more of the carbon dioxide would be absorbed into the ocean，affecting the chemical balance of the sea water，with a potentially harmful impact on shellfish and coral in particular．
"As carbon dioxide dissolves in the water，or seawater in this case，it forms a weak acid （酸），carbonic acid，"Dore explains．"And therefore，as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater，it drives the pH down，and makes it more acidic．"
The seawater Dore and his colleagues have analyzed confirms what the theory predicts．
The effect was particular striking at about 250 meters down，and again at 500 meters．Dore and his colleagues came up with two possible explanations．It could be that surface water picked up CO2 and then moved to those depths．Or there could be a biological explanation．"It's important to realize that the oceans are really becoming acidic．And it can have negative impacts on a whole variety of sea life from fish to coral．It's potentially catastrophic．"
29．What can be the best title of the passage？A
A．Sea Life Facing Danger          
B．Scientist Researching Seawater
C．Oceans Becoming More Acidic     
D．Climate Change Affecting Seawater
30．Which of the following shows the process of the impact of atmospheric CO2 on sea life？B
    a．Sea life is endangered．
    b．CO2 goes into the surface water．
    c．The ocean chemistry is affected．
    d．CO2 decreases the pH and makes the seawater more acidic．
    e．CO2 levels in the atmosphere go up．
A．a(chǎn)→b→c→d→e                   B．e→b→c→d→a
C．a(chǎn)→e→c→d→b                   D．e→d→c→b→a
31．Scientist Robert Dore came to the conclusion based onA．
A．his research and analysis        B．the expectation of other scientists
C．some former theory               D．a(chǎn) major cause of climate change
32．What does the passage want to tell us most？D
A．It takes time to make a scientific study．
B．Atmospheric CO2 is doing harm to sea life．
C．Robert Dore is a committed and serious scientist．
D．Measures should be taken to prevent the potential catastrophe．

4．Dear Highlights，
       My sister is always in a bad mood，which gets me in a bad mood．What should I do？
Tessa，Virginia
    It can be hard to be around someone who is in a bad mood．Since you can't change another person's mood，try to focus on what you can control：your own mood and reaction．
    You might find it easier to stay in a good mood if you leave your sister alone when she feels grumpy （脾氣暴躁的）．The next time she is in a bad mood，go to a quiet place in your house．Read，exercise，draw，listen to music-do something that makes you feel happy．
    Your parents might have some good suggestions for you，too．
Dear Highlights，
    I play soccer，but sometimes I play badly．How can I do better？
Jarom，Utah
    To be good at anything，determination and practice are important．Listen closely to your coach，watch other players，then practice，practice，practice!Professional athletes continue to practice their sports each day，knowing that if they start to get lazy，they won't keep or develop their skills．
    In addition to practicing with teammates，you can work on drills on your own．
    Learning more about the sport may help too．Your coach can likely direct you to some good resources on skills development．
Dear Highlights，
    I was moved up a grade a few years ago．Now，almost everyone in my previous grade asks me why．It wouldn't be a problem，except some boys ask over and over just to be annoying．What do I do？
Allison （by e-mail）
    If you're sure that they are trying to be annoying，you might respond with something humorous．For example，you could say something like"They told me that the lunch lines would be shorter．"Use the situation to turn annoying questions into something to laugh about．
32．What should Tessa do when her sister gets bad-tempered？C
A．Accompany her．B．Change her mood．
C．Try some happy things．D．Leave her in a quiet place．
33．When talking about Jarom's problem，Highlights especially stresses the importance ofB．
A．determination        B．practice   C．team spirit        D．the coach's help   
34．What's Allison's problem？C
A．She cannot get along well with her classmates．
B．Some boys in her class annoy her on purpose．
C．She cannot stand being asked the same question．
D．Her friends cannot accept that she moved up a grade．
35．What can we learn from the answer to Allison's question？D
A．Laughter is the best medicine．B．He who laughs last laughs longest．
