2008年北京中考语文试卷

2008年北京市高级中等学校招生考试语文试卷第Ⅰ卷(共60分)一、选择。
下面各题均有四个选项,其中只有一个..符合题意,请将该答案的字母序号填在题干后的括号内。
(共8分。
每小题2分)1.下列词语中加点字的读音完全正确的一项是()A.刹.那(chà)订.正(dīnɡ)茅塞.顿开(sài)B.贮.藏(chǔ)倾.斜(qīnɡ)轩然大波.(pō)C.解剖.(pōu)酝酿.(niànɡ)爱憎.分明(zēnɡ)D.符.合(fú)乘.客(chènɡ)自给.自足(ɡěi)2.对下列句子中加点成语使用的错误,分析不正确...的一项是()A.王老师不辞辛苦,三顾茅庐....去看望生病在家的李晓明同学。
三顾茅庐:这个成语讲的是刘备三次到草庐中邀请诸葛亮出山的故事。
后用于表示诚心诚意的邀请或拜访。
分析:王老师“看望生病在家的李晓明同学”是去关心他,没有“邀请”“拜访”的意思,所以使用有误。
B.在少年队的比赛中,用青年队队员参赛,简直是拔苗助长....。
拔苗助长:这个成语讲的是宋人用拔苗的方法让禾苗长得更快,结果禾苗都死了的故事。
后比喻不顾发展规律,强求速成,结果反将事物弄糟。
分析:“用青年队队员参赛”这是违反规定的行为,谈不上“不顾发展规律”,所以使用有误。
C.对这件珍藏多年的文物,博物馆要亡羊补牢....的措施,避免造成损失。
亡羊补牢:这个成语讲的是从前一个人的丢了羊以后,及时修补羊圈,从此羊不再丢失的故事。
比喻出了差错,设法补救,免得再受损失。
分析:“珍藏多年的文物”应该并未丢失,不存在“出了差错”,也就不存在“设法补救”的问题,所以使用有误。
D.一味地照搬他人经验,发展本地区经济,无异于守株待兔....。
守株待兔:这个成语讲的是农夫因偶然捡到触树桩而死的兔子,便守在此处,以期再有所获的故事。
后比喻不主动地努力,存侥幸心理,希望得到意外收获。
分析:“一味地照搬他人经验”属于靠突发奇想而得到“意外收获”,含有“侥幸心理”,所以使用有误。

Try laughing for no reason at all. That’s how thousands of people start their day at Laughter Clubs around the world — and many doctors now think that having a good laugh might be one of the best ways to stay healthy.The first Laughter Club was started in Mumbai, India, in 1995 by Dr. M adan Kataria. “Y oung children laugh about 300 times a day. Adults laugh between 7 and 15 times a day,” says Dr. Kataria. “Everyone’s naturally good at laughing —it’s the universal language. We want people to feel happy with their lives.” There are now more than 500 Laughter Clubs in India and over 1,300 worldwide.Many doctors are also interested in the effects (效果) of laughter on our health. According to a 5-year study at the UCLA School of Medicine in California, with laughing there is less stress in the body. Laughter improves our health against illness by about 40%.So, what happens at a Laughter Club? I went along to my nearest club in South London to find out. I was quite nervous at the beginning of the class, to be honest — I wasn’t interested in laughing with a group of strangers, and I was worried about looking stupid. Our laughter teacher told us to clap our hands and say “ho ho ho, ha ha ha,” while looking at each other. Howe ver, our bodies can’t tell the difference between fake laughter and real laughter, so they still produce the same healthy effects.Surprisingly, it works!

Ben knows that this day honors an important man, but Ben does not feel connected to him. However, the small-world theory (理论) connects Ben to Dr. King. Ben’s mom (0) has a close friend, Amy (1). Amy’s uncle, Mark (2), once met and spoke to John Carter (3), the son of President Jimmy Carter (4). Jimmy Carter knew Dr. King (5). In a way, Ben is only “five people away” from Martin Luther King Jr.The small-world theory says that everyone in the world is connected through a short chain(链条) of people they know. Another name of this chain is degrees of separation. Each degree is a step that separates a person from someone he or she does not know. There are zero degrees of separation between a person and the people he or she knows directly. This means that there are zero degrees between Ben and his mom. There is one degree of separation when just one person separates someone from a person he or she does not know. Ben knows his mom, but he hasn’t met her close friend Amy. Therefore, Ben is one degree away from Amy. As the chain continues, Amy’s uncle, Mark, is two degrees. John Carter is three degrees, and his father is four degrees. Dr. King is five degrees away from Ben. The theory says that there are no more than six degrees of separation between any two people in the world.The small-world theory has a lot to do with math. The theory assumes (假定) that each person knows 100 people. Each one of those 100 people knows 50 different people. Each of those 50 people knows another 50 people, and so on. When someone continues the calculation to six degrees, it is like this: 100 × 50 × 50 × 50 × 50 × 50 = 31.25 × 109. This number is greater than 31 billion (a billion = a thousand million). There are over 6 billion people in the world. These numbers show it is possible that six degrees of separation could include everyone in the world.Does the small-world theory work? No one has ever proved it. Maybe the theory just invites people to think a little more about their places in the world.8. Ben is two degrees away from __________.A. Jimmy CarterB. John CarterC. AmyD.
