11.词义辨析.promt是“及时的,迅即的”.significant意义重大的,tough艰巨的,principal主要的.
12.词义辨析.movement指大规模的运动.activity是活动,词义太宽泛；campaign也是运动,但一般指上街游行那种；action是行动,是相对是思想来说的.
13.句子结构.forget to do sth.这个你应该没问题,你的问题应该是在后一个空,when/while doing sth.这种用法很常用啊!当when/while前后主语一致时都可以用,就相当于when sb.does sth..是一种省略的说法而已.
14.词义辨析.be guilty of对……有罪,对……负有责任,careful小心的,impatient不耐烦的,glad高兴的.
15.词义辨析.reveal是“揭示”,require要求,observe观察,remind提醒.
16.词义辨析.dimiss解散,distract使分心,decay腐烂,destroy毁掉.
17.句子结构.sb.spend some time doing sth.是固定的,一定要用doing!
18.句义理解.句意是“经济复苏”,要选一个名词,马上排除BCD,因为这三个都是动词.recovery是“康复,复苏”.
19.句义理解.句意是“当我小时候,没有人曾预料到我的将来这么成功”,选“预料”,排除CD.protest反对,protect保护.A和B都有预告的意思,但B更倾向于“天气预报”那种,predict是“预言”,最符合题意.
20.句义理解.at the end of one's rope指黔驴技穷,没办法了.所以应该选but now,关于这个now嘛.其实AC都可以的,C更准确一些,强调现在没招了,选择题嘛,选最佳的!
