不是高手(只是对英文有兴趣)
还是想和楼主讨论一下下
1)Let us suppose:the strength of steel and the temperature of boiling water
would vary ______ whether human lives were threatened by a given situation.
(a) deciding on (b)dependent on (c) depend on (d) depending on
第一题我觉得是动词而不是prep.(depend on 应该是phrasal verb(片语动词/动词片语))
depend(动词)转为depending(Ving:有主动之意)引导whether子句修饰前头的vary
题目的意思翻成中文为:钢的硬度与滚水温度会____人类性命是否遭受威胁而改变
答案中a和d的选项均为Ving(主动)
根据题意
选择depending on (...依据)而非deciding on(....决定)
2)Because people often have illusions that we can see ourselves in the
biographies of famous people,screen biographies tend to be dramatically
______.
(a)satisfy (b) satisfied (c) unsatisfied (d) unsatisfying
第二题从情绪动词的用法来判断即使看不懂句子也能选出正确的答案
情绪动词的p.p.当形容词使用
用来修饰人
情绪动词的Ving当形容词使用
用来修饰物
所以答案里头只有D可以用来修饰物 -- screen biograhpies
以上个人浅见仅供参考
