【语篇导读】 科学家研究发现有氧运动可以有效治疗偏头痛。
1.解析:
选C。
推理判断题。
根据文章最后一段可知,规律的有氧运动或许可以治愈偏头痛,故C项正确。
根据文章第十段可知A项表述不正确;根据文章第四段可知,topamirate有副作用,故B项不正确;根据文章第九段中cardiowon'tbethesolutionforeveryone可知,D项不正确。
2.解析:
选C。
词义猜测题。
画线词所在的第七段讲的是流汗会缓解压力,头痛通常由压力引起,如果消除压力,疼痛就会缓解。
由此可知trigger意为“引发,激发(尤指一系列事件)”,与cause意义相近。
3.解析:
选D。
细节理解题。
根据文章第八段Thefeelgoodchemicalsproducedwhenyouexerciseactuallyblockyourpainsensors,actingasanaturalpainkiller.可知,人类运动的时候,产生令人感觉好的化学物质,能够阻挡疼痛传感器,像一种天然的止痛药一样起作用。
4.解析:
选A。
主旨大意题。
通读全文可知,文章主要介绍了有氧运动或许可能治愈偏头痛,因此A项作为文章标题最适合。
B项在文章中没有被提及;C、D两项在文章中略有提及,但并非主题。
B
