我是真的不懂……
5、He ________ admitted the whole story.
A、much as B、as much as C、as many as D、as great
但这题我觉得少了点东西,

Answer 1

1、the useful thing是特指的一件有意义的事情所以用the(可能前面有语境,就是在说这件事,题中这句话表示一个决定),而useless thing则是泛指所以用a
2、呃...这个those经常这么用,后面的“doing ...”是对those的一个修饰,是一个定语从句,宾语是those;这个地方选B不对,因为whomever/whoever(当然还有whatever等等)只能用来引导让步状语从句而不能引导主语宾语从句,不能放在这个地方当宾语
3、我觉得答案错了...应该选D,是两者之间嘛```不能太相信答案了
4、这是表示比例的一种用法记住就行哈```什么1 out of 5就是五分之一啦,4 out of 9就是九分之四啦都一样的,“...out of...”来表示比例
5、as much as记得不是很清楚了...呵呵我记得是表示强调吧,就是“他非常认同整个事件”的意思
