在考研阅读中，不论是阅读文章还是解答题目，标点符号都可以起到画龙点睛的妙用。
一：逗号
两逗号中为插入语时，看暂时跳读
1. For a while it looked as though the making of semiconductors, which America had invented and which sat at the heart of the new computer age, was going to be the next casualty.（2000，Text 1）
半导体制造业是美国发明的，而且是新的电脑时代的核心产业，一度被认为会成为下一个受害者。
2 .Some huge American industries, such as consumer electronics, had shrunk or vanished in the face of foreign competition. （2000，Text 1）
面对国外的竞争，美国一些大型产业出现了萎缩或者倒闭，比如消费电子业。
3. This means that, for the first time, there will be an excess of boys in those crucial years when they are searching for a mate. （2000，Text 2）
（做男人总是有危险。男女出生比例大约为105:100，但到成年时，这个比例就差不多会降到持平状态；而在70岁老年人中，女性人数是男性人数的两倍。但是男性死亡率高这一普遍现象正在被改变。现在，男婴存活率几乎和女婴一样。）这意味着到了找对象的关键几年，男性人数将首次超过女性。
二： 冒号
进一步解释说明前句中的事物或现象
1. We live a society in which the medicinal and social use of substances (drugs) is pervasive: an aspirin to quiet a headache, some wine to be sociable, coffee to get going in the morning, a cigarette for the nerves. （1996，Text 4）
60. The word "pervasive" (Line 1, Paragraph 2) might mean ________.

2. There is another way to commit evolutionary suicide: stay alive, but have fewer children. （2000，Text 2）

3. I have discovered, as perhaps Kelsey will after her much-publicized resignation from the editorship of She after a build-up of stress, that abandoning the doctrine of "juggling your life," and making the alternative move into "downshifting" brings with it far greater rewards than financial success and social status. Nothing could persuade me to return to the kind of life Kelsey used to advocate and I once enjoyed: 12-hour working days, pressured deadlines, the fearful strain of office politics and the limitations of being a parent on "quality time". (2001, Text 5)
69. "Juggling one's life" probably means living a life characterized by ________.
[A] non-materialistic lifestyle
[B] a bit of everything
[C] extreme stress
[D] anti-consumerism
三：分号

1.This is no flash in the pan; over the past couple of years, inflation has been consistently lower than expected in Britain and America. （1997，Text 5）
这不是昙花一现，在过去几年里，英国和美国的通货膨胀率始终低于预测水平。
69. The sentence "This is no flash in the pan" (Line 5, Paragraph 3) means that ________.
[A] the low inflation rate will last for some time
[B] the inflation rate will soon rise
[C] the inflation will disappear quickly
[D] there is no inflation at present
2. For us, this means that evolution is over; the biological Utopia has arrived. Strangely, it has involved little physical change. （2000，Text 2）
对于我们来说，这意味着进化已经结束，生物学上的乌托邦时代已经来临。
3. [2004 Text 1] Instead, the best strategy is to use the agent as a kind of tip service to keep abreast of jobs in a particular database; when you get E-mail, consider it a reminder to check the database again.
The expression "tip service" (Line 3-4, Paragraph 3) most probably means________.
[A] advisory [B] compensation [C] interaction [D] reminder

2. But in the past 100, 000 years-even the past 100 years-our lives have been transformed but our bodies have not. （2000，Text 2）
可是过去10万年--甚至在过去100年里，我们的生很活发生了变化，但我们的身体却没有改变。
