答案:   1. to—on   “给……造成的压力”应表述为 one’s pressure on something,名次pressure通知和介词on搭配。   2. takes—took   句中的时间所指是1997年,所以必须用一般过去时。   3. popular–^will   这是一个时态问题。时间状语by the year 2050 是一个非常重要的信息,它表示将来的某一个时间点,这时主句应该用“将来完成体”will have done.   4. who—that/which   关系分句的先行词是population,尽管population的意思是“人口”,但是它的概念并不是somebody,而是something,所以关系代词应该用that或者which。   5. away—from   shield something from something 的意思是“遮挡……使得不受……的侵害”。   6. dead—deadly   deadly 表“致命的”。   7. each—every   表示频率“每……中有……”,这里应该用every,而不能用each,例如:once every week,不能说 once each week。   8. ^diagnosed—were   diagnose(诊断)是一个及物动词,可以说be diagnose with/as……例如:   The child has been diagnosed as having flu.   9. produce—reproduce   produce 的意思是“生产,制造”,reproduce的意思是“生殖,繁殖”。   10. ways—way   find one’s way into something 意思是“(设法)走进,进入”。在这个表达中,way只以单数形式出现。这样的词组还有:push one’s way into, work one’s way into, elbow one’s way into等。
