Ⅴ.阅读理解

Everyone needs friends. We all like to feel close to someone. It is nice to have a friend to talk, laugh and do things with. Surely there are times when we need to be alone. We don't always want people around. But we would feel lonely if we never had a friend.

No two people are the same. Sometimes friends don't get along well, which doesn't mean that they no longer like each other. Most of the time they will go on being friends. Sometimes friends move away, and then we feel very sad. We miss them much, but we can call them and write to them. Maybe we would never see them again, and we can make new friends. It is surprising to find out how much we like new people when we get to know them. Families sometimes name their children after a close friend. Many places are named after men and women, if they are friendly to people in a town. Some libraries are named this way. So are some schools. We think of these people when we go to these places.

There's more good news for people, if they have friends. These people live longer than those people who don't have friends. Why? It could be that they are happier. Being happy helps you stay well. Or it could be

just knowing that someone cares, if someone cares about you, you take better care of yourself.

1．The first paragraph tells us ________.

A. none needs friends

B. we need to be alone

C. we always need friends around us

D. making friends is the need in people's life

2．Which of the following is the most probable place people name after friendly people?

A. A house.

B. A room.

C. A library.

D. A village.

答案与解析 C 细节理解题。根据文章第二段倒数第三句可知，图书馆以友好的人的名字命名。

3．If people have friends, they would live longer, because ________.

A. they feel happier and healthier

B. they get a lot of help from their friends

C. they take better care of themselves

D. both A and C

答案与解析 D 细节理解题。根据文章最后一段可知，如果人有了朋友，会感到幸福、快乐，而且会更好地照顾自己，故能长寿。

4．This passage tells us ________.

A. that people are all friends

B. that people need friends

C. how to get to know friends

D. how to name a place

行为。 B．在动物身上，无论从形态结构、生理过程和行为方面去分析，尽可能节省能量的例子比比皆是。 C．地震发生后，当地政府及解放军部队全力救助，目前灾区群众已住进了临时帐篷，防止余震再次发生。 D．有人认为科学家终日埋头科研，不问家事，有点不近人情，然而事实却是对这种偏见的最好说明。 解析B项中应将“和”改为“还是”；C项不合逻辑，应为“预防余震发生”；D项中“事实是说明”正好说反了，依句意应是“事实正是对上述说法的反驳”。 答案 A 5．下列句子中标点符号的使用，不正确的一项是() A．马驹常常欢快地连续扬起前蹄，轻盈地蹦跳；猴类喜欢在地上翻滚，拉着树枝荡秋千……单独游戏时动物显得自由自在。 B．这些科学家认为，动物游戏是为了“自我娱乐”，而自我娱乐是动物天性的表现，正像捕食、逃避敌害，繁殖行为等是动物的天性一样。 C．这几种假说，哪一种更有道理？动物的游戏，究竟是为了“演习”，为了“自娱”，为了“学习”，还是为了“锻炼”？研究者们各执己见，众说纷纭。 D．电视剧《水浒传》标明作者为施耐庵、罗贯中，引起许多观众的疑惑：《水浒传》的作者不是施耐庵吗？怎么又多出个罗贯中？ 解析B项中，第二个“自我娱乐”也应加引号，“逃避敌害”后的逗号应改为顿号，因为三者处在同一等级的并列上。 答案 B 6．下列语句排列正确的一项是() ①否则，我就只能相信，这些曲调是真正的音乐。 ②那些歌也许是有关航行，或有关浮游节肢动物的来源，或有关领地界限的简单而实打实的叙述和声明。 ③当然还有其他方法来解释鲸鱼之歌。 ④除非有一天有人证明，这些长长的、缭绕的、执著的曲调，被不同的歌唱者重复着，又加上了它们各自的修饰，这不过是为了向海面下数百英里之外传递像“鲸鱼在这儿”之类寻常的信息。 ⑤但迄今证据还没有得到。 A．③①②⑤④B．②③①④⑤ C．⑤②③①④D．③②⑤④① 解析注意“否则”“除非”“但”等词。

双基限时练(二十一) 1．已知a ＝(－3,4)，b ＝(5,2)，则a ·b ＝( ) A ．23 B ．7 C ．－23 D ．－7 解析 a ·b ＝－3×5＋4×2＝－7，故选D. 答案 D 2．已知向量a ＝(1，－1)，b ＝(2，x )．若a·b ＝1，则x ＝( ) A ．－1 B ．－12 C.12 D ．1 解析 由a ＝(1，－1)，b ＝(2，x )可得a·b ＝2－x ＝1，故x ＝1. 答案 D 3．若非零向量a ，b ，满足|a |＝|b |，(2a ＋b )·b ＝0，则a 与b 的夹角为( ) A ．30° B ．60° C ．120° D ．150° 答案 C 4．已知A ，B ，C 是坐标平面上的三点，其坐标分别为A (1,2)，B (4,1)，C (0，－1)，则△ABC 的形状为( ) A ．直角三角形 B ．等腰三角形 C ．等腰直角三角形 D ．以上均不正确 解析 AB →＝(3，－1)，AC →＝(－1，－3)，BC → ＝(－4，－2)， ∴|AB →|＝10，|AC →|＝10，|BC → |＝20.

∴|AB →|＝|AC →|，且|AB →|2＋|AC →|2 ＝|BC → |2＝20. ∴△ABC 为等腰直角三角形，应选C. 答案 C 5．已知a ＝(0,1)，b ＝(33，x )，向量a 与b 的夹角为π 3，则x 的值为( ) A ．±3 B ．±3 C ．±9 D ．3 解析 cos π3＝a ·b |a |·|b |＝x 27＋x 2， ∴2x ＝27＋x 2，且x >0，∴3x 2＝27，∴x ＝3. 答案 D 6．已知向量a ＝(1,2)，b ＝(2，－3)，若向量c 满足(c ＋a )∥b ，c ⊥(a ＋b )，则c ＝( ) A.? ????79，73 B.? ????－7 3，－79 C.? ?? ??73，79 D.? ?? ??－7 9，－73 解析 不妨设c ＝(m ，n )，则a ＋c ＝(1＋m,2＋n )，a ＋b ＝(3，－1)， 对于(c ＋a )∥b ，则有－3(1＋m )＝2(2＋n )． 又c ⊥(a ＋b )，则有3m －n ＝0， ∴m ＝－79，n ＝－7 3. 答案 D 7．已知向量a ＝(3,1)，b ＝(1,3)，c ＝(k,2)，若(a －c )⊥b ，则k ＝________.

＝(x 2 ＋ln x) ? ?? a 1＝a 2＋ln a －1， 又?? 1 a (2x ＋ 1 x )d x ＝3＋ln 2， ∴a ＝2. 答案 D 4.? ?π－πcos x d x 等于( ) A ．2π B ．π C ．0 D ．1 解析 ? ?π－πcos x d x ＝sin x ? ?? π－π＝sinπ－sin (－π)＝0. 答案 C 5．设f(x)＝????? x 2 (0≤x<1)， 2－x (1
