题目内容

Those _______ suffer from headache will find they get relief from this medicine.

A．that B．who C．which D．whom

【答案】

【解析】

试题分析：考查定语从句。本题定语从句的先行词是those，定语从句关系动词who指代those在句中做主语。当先行词是指人的those的时候，如果使用关系代词，要使用who,而不是that。Which的先行词必须是物，whom在句中做宾语。句意：那些患头痛病的人将会从这种药里得到缓解。故B正确。

考点：考查定语从句

点评：定语从句是高考从句中必考的语法，在阅读文章中出现的频率也很高。关键在于分析句子结构，定语从句中如果既不缺主语，也不缺宾语和表语，就要考虑是否用关系副词或whose作定语，意为“谁的”。至于如何判断缺不缺主或是宾语，尤其是缺宾语的情况，要将先行词带到定从中谓语动词之后看是否符合逻辑搭配，如符合则缺宾语，如不符合就不缺。

Sleeping in on Saturday after a few weeks of too little shuteye may feel refreshing, but it can give a false sense of security.

New research shows long-term sleep loss cannot be cured that easily. Scientists researched the effects of short- and long-term sleep loss and found that those who suffer long-term sleep loss may function normally soon after waking up, but experience steadily slower reaction times as the day goes by, even if they had tried to catch up the previous night.

The research has important safety significances in an increasingly busy society, not just for shift-workers but for the roughly one in six Americans who regularly get six hours or less of sleep a night.

“We know that staying awake 24 hours without sleep will affect your performance to do all sorts of things, and this effect equals to drinking too much when driving,” said lead researcher Dr. Daniel Cohen of Boston’s Brigham and Women’s Hospital. But when those who suffer long-term sleep loss become all-nighters, “the harm is increased ten times,” Cohen said.

The National Institutes of Health says adults need seven hours to nine hours of sleep for good health. Regularly getting too little sleep increases the risk of health problems, including memory impairment and a weakened immune system. More immediately, too little sleep affects reaction times; sleepiness is to blame for car crashes and other accidents.

It has critically important complicated and unexpected results for anyone who works “crazy hours” and thinks they are performing fine with a few hours of weeknight sleep, said Harris, director at New York’s Montefiore Medical Center. “Don’t think you can just bank up your sleep on the weekend, because it doesn’t work that way,” he warned.

A. to sleep more time B. to sleep in on Saturday

Friendship can deeply affect the physical and mental health of both men and women. Studies show that people who have no friends or who are lonely, are more likely to die earlier, get sick more often and suffer greater physical wear and tear（折磨）than those who have a support system of friends.

Sometimes, family members may be more likely to give you advice or tell you what you don’t want to hear. It may not be as good as a friend who will listen to you and guide you, but support your decisions anyway. The most important elements about friendship are those who suffer support and do not judge your decisions based on society. www.

One reason for the link between social support and good health practice seems to be that people who feel cared for by others are less stress-out and are protected against the symptoms（症状）of depression and loneliness.

Generally, women benefit most because of how they deal with stress. Women are more social in how they deal with stress than men, while men are more likely to have a “fight or flight” reaction. Women also tend to have larger, denser social network, in which more people know each other and help each other, while men typically have smaller groups of friends and will rely on their wives or other important people for more support. While all these affect people psychologically（心理上）, friendship brings comfort that reduces the ill effects of stress, and the sex difference also contributes to the difference in the length of one’s life time.

In the author’s opinion, a real friend should _________.

A．tell you what to do even if you refuse to hear it.

C．judge your decision according to his/her experience.

D．give you advice but respect your own decision.
