(2分)从中可见他是一位深谋远虑(远见卓识)的君主。
(1分)【参考译文】晋文公要在城濮和楚军交战,文公征询咎犯的意见,问咎犯:“这仗该怎样打?”咎犯说:“如果是做仁义的事,那就不该讨厌忠诚守信用;如果是和敌军开战,那最好是兵不厌诈。
现在既然是和楚军交战,君王你就只管使用欺诈就可。
”文公辞别咎犯后,又去请教雍季,雍季回答说:“放火来焚烧山林,尽管暂时能打获到很多野兽,但是最终会到无兽可猎的地步;用欺诈手段对付人,虽然一时能获得很多利益,但到最后一定会无利可图。
所以君王还是正大光明行事为好。
”文公没有听从雍季的话,而是采纳了咎犯的计策,和楚军开战时用计大败楚军。
回国以后,嘉奖有功人员,首先是奖赏雍季,然后才奖赏咎犯。

Jason regards travelling as a kind of exercise. BOn July 2, 1937, Amelia Earhart, an American pilot (飞行员),and Fred Noonan left New Guinea for Howland Island in the Pacific. This was the most dangerous part of their tour around the world. Earhart had trouble soon after the plane took off. The weather was very bad, so she had to fly at about 3,000 metres high. Going this high, the plane used fuel quickly. Over 10 hours later, Earhart and Noonan got close to Howland Island. Near Howland Island, a ship was waiting for the plane. Earhart got in touch with the ship and said, “We don't have enough fuel.”The ship tried to keep in touch with her but got no answer. Finally, the ship called for help. People looked for Earhart and Noonan for days. However, they found nothing. What happened to Amelia Earhart? No one knows for sure. Some people think during the flight she probably moved in the wrong direction because the weather was bad and she got lost. Soon after, her plane ran out of fuel, and she died at sea. Another idea is that she survived (幸存) the plane crash, swam to a lonely island, and later died there. Still others think she survived the crash and secretly returned to the US with a new identity (身份). Till now, none of these ideas has been confirmed. People are still wondering about them. No matter what happened, Earhart probably died as she wished “When I go,”she said,“I'd like to go in my plane.第 4 页()30. What was the main purpose of Amelia Earhart's flight? A.

Earhart wasn't afraid of any danger.D. Earhart loved flying very much. CBesides the spelling of the word, there are clearly many differences between American and British humor.There is a common belief (信念) in the UK that Americans don't understand irony (讽刺). This is of course not true. But what is true is that Americans don't use it all the time. Irony may show up in American comedies, but people there don't use it as much as the British do in daily life. However, irony is common in British culture. It actually runs in the blood of the British people. They use it as a way of playing with their friends and laughing at their enemies as well as themselves in everyday conversations. This may sometimes make people unhappy if the listeners are not used to it. They may also feel embarrassed.Things are different in America. After American people use irony, they feel the need to make a joke clearer so that it will not make other people uncomfortable. Humor is tied so much to culture. American jokes are clearer and more forward. British jokes, on the other hand, are more subtle (巧妙的)and usually with a hidden meaning. This may result from the fact that British culture is more reserved (矜持的)than American culture. However, we still find that certain American comedies have made huge success in Britain.Therefore, although there are differences between both comic styles, there is still an appreciation (欣赏)and understanding of the other's sense of humor.

I hid behind my mother and she hid behind her grandmother, scared to look at each other.Soon, we lost the shyness and started playing with each other, like going to each other's houseand having sleepovers. In the 7th grade she was going through family problems. However, every summer we would always sit together and watch movies on TV and talk about all the boys we liked.It was last year when I noticed the problem. She suffered from clinical depression (抑郁症),and had to go to the hospital during the day. I was very sorry for her at first. But with the late night calls, and meeting each other halfway up the street at midnight, we still kept in touch. I wanted to be there for her since her new best friend left her, and I knew I still cared about her like a sister. Yesterday she came to me and said, “I never knew what a best friend was until you were the only person that would stop me from cutting myself and make me feel better about myself and my problems. You didn't know this but I was trying to kill myself that night when you called me and I was crying. I owed (欠) you so much, and you didn't even know you were helping me.We both cried. And I learn a kind of lesson from my life —never give up your friends. Even if they aren't as cool as others, or people think they are crazy, they need someone there. If you leave them, you will only be very sorry. So if friends need you, and you care for them, you should be always there for them.()38.

EHave you ever had trouble sleeping in a new place? Lots of people do. And now researchers from Brown University in Rhode Island think they know why. They found that half of the brain “remains more awake”than the other half when people are trying to sleep in a new place.The sleep findings were reported in Current Biology by Brown University. In the report, the researchers say many people say they have a harder time sleeping the first night at a hotel or other places outside their homes. They call it “first-night influence”. “In Japan people always say, ‘If you change your bed, you can't sleep,'”said Yuka Sasaki, one of the report's writers. “You don't sleep very well in a new place. We all know about it.”The researchers measured brain waves (测量脑电波)for 35 volunteers over two nights in a laboratory. The two nights were a week apart (间隔).They found during the first night the left half of the brain was more active than the right half. “This was during the first deep-sleep period,”the researchers said.Sasaki said a lot of questions remained.Researchers did not keep measuring brain waves all night long. So, they don't know if the left half keeps “monitoring”all night, or whether it “works in shifts (轮换) with the right half later in the night”. They also do not know why the brain activity, at least during the first period of deep sleep, is always on the left half.For some, this research may be useful. It is good to know that our brain is “looking out for us”in a new place. But it may not help with sleep. That brain activity, at least according to this new research, makes it harder for people to sleep well.()42. According to the researchers, why do people have trouble sleeping in new places? A. Because they aren't used to sleeping on the new beds.B. Because half of the brain is more active than the other half during the night.C. Because they try to look out for themselves by staying awake.D. Because they miss their other family members. ()43. What does the third paragraph mainly talk about? A. How the 35 volunteers slept in new places. B. How the researchers did the research. C. What the brain wave is.D. When the first deep-sleep period is.()44. What does the underlined word “monitoring”mean in English? A. Smelling. B. Hearing. C. Watching. D. Saying.()45. Which of the Mowing is NOT true according to the passage? A. The researchers talk about the first-night influence in their report. B. The research is not always useful.C. The brain activity at night doesn't help with sleep.D. The reason why the brain activity isn't on the right half has been discovered.第 7 页第二卷非选择题(25分)IV.语法填空:用所给单词的适当形式填空,未提供单词的根据上下文填入适当的词。
