Answer 1

【答案】

【1】E

【2】G

【3】F

【4】C

【5】A

【解析】

试题分析：本文属于说明文阅读，介绍了在现在空气污染情况较为严重的情况下，我们可以采取的四种方法让自己少吸入被污染的空气。

【1】E 根据横线前句You may think that there is nothing you can do about the air you breathe.也许我们会认为对于我们吸入的空气质量我们没有办法控制。在文章下面提出了四个改变我们吸入空气的建议。故E项“However, there are easy ways to protect yourself against smog and air pollution.有一些很容易的方法保护我们不受雾霾和空气污染的伤害”属于上下文的过渡句。符合上下文串联。

【2】G 根据横线前句You need a proper N95 mask.人们需要N95型号的口罩。且横线后句说明这一口罩的作用。所以横线句应该说明这一型号口罩的使用方法。故G项“Its straps should be securely fastened behind your head, to hold the mask against your face”符合上下文串联。

【3】F 本段标题“Drink lots of water and stay hydrated”建议我们多喝水保湿。根据横线前句This makes it important to stay in the shade and drink lots of water to stay hydrated, especially before, during, and after exercise.高温高湿要求我们在锻炼前、中、后都要多喝水，那么本句应该说明水的作用。F项“Besides, water will not only quench your thirst, but help clear your breathing passages.”恰好在说明喝水的重要作用。故F项符合上下文串联。

【4】C 本题标题为“Stay indoors”建议我们待在室内，尽量不外出。所以C项“If you want to go out, go to malls, and eat in enclosed spaces.如果你想外出，就都购物中心在相对封闭的空间里吃饭”符合本段中心思想。

【5】A 根据本段最后一句“So, keep the windows closed and use air purifiers to protect your home.”可知当人们在室外抽烟的时候，我们最好关闭门窗并使用空气净化器来保护我们的家。可知A项“Protect your home”符合上下文串联。
