1. 【答案】A

【解析】句意:极端温度能直接导致死亡。C和D用在这里意思明显说不通,故排除C和D;根据常识，极端温度是不会导致生命改变的，故排除 B。所以 A项正确。

2.   【答案】A

【解析】moreover 此外;however 然而;hence 因此;instead 代替，反而。文章阐述健康和气候的关系，前面讲到了极端温度导致人失去生命，这里又讲有些严重的疾病只出现在温暖的地区，下文还有 Finally 的提示,所以A正确。其他三个选项用在这里语意不连贯。

3.   【答案】B

【解析】句意:最后，温暖的气温会增加空气和水的污染，这反过来又会损害人类的健康。此处说的是温度对人类健康的影响,所以选 B,其他三项和文中所提到的内容不相干。

8.   【答案】D

【解析】句意:更高的空气温度也提高了地平面臭氧的浓度。A、B、C三项不符合文意，故排除ground level意为“地平面”符合文意，故选D。

9.   【答案】A

【解析】此处意为:但是在低层大气中,臭氧是一种有害的污染物。harmful有害的;beneficial有益的;infectious 传染性的;useful有用的。前面一个分句所说的是臭氧层的好处,诺气转折后，此处是讲它的害处，B和D都与句意相反，排除:C表述不恰当，也排除。故选 A。

10. 【答案】B

【解析】本句与前句是递进关系所以要用表示递进关系的词。but表示转折，故排除A;thus 表示结果,故排除 C;or 表示选择,故排除 D;even 表示递进,故选B。

11. 【答案】C

15. 【答案】C

【解析】这里句意为:······治疗传染性疾病的蔓延，并在其他的健康问题发生时作出反应。apply 申请,reply 回复，direct 指导，都不符合文意，故排除A,B_D。respond to意为“对·...··作出反应”

四、书面表达。

Dear friends，

We all know the old saying：“All work and no play makes Jack a dull boy.”That’s why I’d like to share

【参考范文】

Dear friends，

We all know the old saying：“All work and no play makes Jack a dull boy.”That’s why I’d like to share my opinions about how to reduce pressure from our study.

First, we need enough sleep at night because staying up too late is bad for our health. Second, we must take some sports as sports activities help build a strong body for us to face our daily study. In addition, we may have our parents plan an occasional short holiday since a holiday is a welcome relief from the pressure of work. Only when we are healthy and energetic can we become prepared for any hard task in our schoolwork and get fruitful results.

Sincerely，

Li Hua
