p86

A.drawing pictures
B.in drawing pictures
p87
27.It is a common sense that new ideas have to be tested many times before______.
A.being fully accepted
B.fully accepted
我选B,答案A
45.Even if_____harder,Mike still has trouble with the subject of maths.
A.working B.works
我觉得应该是even if he works或者Having worked
解答:
18. 选A
强调结构，强调主语drawing pictures，我们平时见到的多是一名词，只不过这里主语是一个名词性短语。
27. 选A
that new ideas have to be tested many times before___.
是主语，it是形式主语。意思是：许多观点在被完全接受之前要经过多次反复检验，这是一个常识。后面短语表示被动不假，关键是前面接介词before或after等介词时，be动词不能省略。
45. 选A
考查现在分词短语的用法。当现在分词短语接在连词Even if后时
相当于一个让步状语从句。Even if_____harder,Mike still has trouble with the subject of maths.=Even if he works harder,Mike still has trouble with the subject of maths.
