     Valentine's Day just passed and it made me remember a middle school student I know who may be in love.

     I think there are two ideas of middle school "love". One is temptation: Girls dress beautifully and act giggly.

Boys are popular and attractive.

     Then there is the other kind: attraction that may or may not be love. The student I know is like that. She

has a friend called John whom she has feelings for, but she can't decide if it's love or friendship. In her words:

     "I wonder whether he is my ideal boyfriend. I want someone cool and kind who holds the same values as

me. He isn't any of these. So sometimes I wonder if I'm only attracted and deciding to break up with him now.

But he is attractive, and he isn't foolish. He may not be an "A" student, but he's intelligent and clever. I wonder

if I only pity him for the hard times he has had. He knows how to make me laugh. We both sing and act. We

had several classes together last year. He can be very sweet."

     I'm moved by this because it's hard to find a student who has such real thoughts. It seems that

everyone thinks only of how "hot" someone is, without acting more wisely.

     For some people, Valentine's Day might mean nothing. But for others, it could mean a lot. What about you,

young man?

分,每小题阅读下列文段,完成后面题目。

(1)做了再说,做了不说,这仅是闻一多先生的一个方面——作为学者的方面。 

(2)闻一多先生还有另外一个方面——作为革命家的方面。这个方面,情况就迥乎不同,而且一反既往了。 

(3)作为争取民主的战士,青年运动的领导人,闻一多先生“说”了。起先,小声说,只有昆明的青年听得到;后来,声音越来越大,他向全国人民呼喊,叫人民起来,反对独裁,争取民主!

(4)他在给我的信上说:“此身别无长处,既然有一颗心,有一张嘴,讲话定要讲个痛快!”

(5)他“说”了,跟着的是“做”。这不再是“做了再说”或“做了也不一定说”了。现在,他“说”了就“做”。言论与行动完全一致,这是人格的写照,而且是以生命作为代价的。

(6)1944年10月12日,他给了我一封信,最后一行说:“另函寄上油印物二张,代表我最近的工作之一,请传观。”

(7)这是为争取民主,反对独裁,他起稿的一张政治传单!

(8)在李公朴同志被害之后,警报迭起,形势紧张,明知凶多吉少,而闻先生大无畏地在群众大会上,大骂特务,慷慨淋漓,并指着这群败类说:“你们站出来!你们站出来!”

(9)他“说”了。说得真痛快,动人心,鼓壮志,气冲斗牛,声震天地!

(10)他“说”了:“我们要准备像李先生一样,前脚跨出大门,后脚就不准备再跨进大门。”

(11)他“做”了,在情况紧急的生死关头,他走到游行示威队伍的前头,昂首挺胸,长须飘飘。他终于以宝贵的生命,实证了他的“言”和“行”。

(12)闻一多先生,是卓越的学者,热情澎湃的优秀诗人,大勇的革命烈士。

(13)他,是口的巨人。他,是行的高标。

小题1:对第三段“小声说声音越来越大”所表达的意思理解不正确的一项是(    )

A.开始他作为一名进步知识分子,因不满于反动派的统治,只在昆明青年中宣传民主 。

B.后来他逐渐成为一名民族战士,在全国范围宣传动员革命,争取民主反对独裁 。

C.面对敌人的卑鄙的行径,闻一多越讲越气愤,慷慨激昂,声调自然也越来越高。

D.小声到大声,实际上是闻一多从学者像战士的转化,反映了他思想的转变过程。小题2:下列句子最能体现第(5)段中是以生命作为代价的一项是(   )

A.此身别无长处,仍然有一颗心,有一张嘴讲话定要讲个痛快!

B.另函寄上油印物二张,代表我最近的工作之一,请传观 。

C.你们站出来!你们站出来!

D.我们准备像李先生一样,前脚跨出大门,后脚就不准备在跨进大门。小题3:对第13自然段“他是口的巨人,他是行的高标”一句的作用分析不正确的一项是(     )

A.总结全文 。

B.是对闻一多先生人格高度概括和总结。

C.深化主题 。

A.夹叙夹议是本文表达上的最大的特点,既摆事实又讲道理。
