这是it强调句型, 强调时间状语从句"not until man had learned how to make iron and steel" not和until作为句型搭配用法,往往是分开的,但是如果要强调,则会合在一起,即:It is/was not until...that...此时,主句的否定结构到了强调句中药变为肯定结构。比如:1.His father won't come b...

你看到这句“He seems to be working.”是否会明白?"to be working" 是不定式的进行形式,作系动词seem 的表语。单单WORKING 可以看作是现在分词。例句中“to be redirecting aggression in a threat display” 是不定式的进行形式,作系动词seem 的表语。“redirecting”是现在分词, aggression是它的宾语,“in a thr...

我的理解是:这里AS 是介词,having died 是动名词。regard sb as clever, 可以理解成“regard sb as being clever", as 也是介词。还有我本人对类似”STOP SB FROM DOING STH“,”CHARGE SB WITH DOING STH"成分也很纠结。实际上这种结构跟普通的宾补结构还是有区别的。这里有很多老师曾分析的很好。如果不细...

我认为"You think you pretty cool"其实是"You think you are pretty cool?"省略了“are"。美国口语里这种说法不少见。美剧里经常有”You good?"是“You are good?"的省略。

Occur 是不及物动词,意思有“发生” 或“被想到”,不能有被动语态。”Occur to him“是“被他想到”的意思.It是形式主语,真正主语是"that he had forgotten to turn off the gas in a hurry".主动语态就含被动意义,这样排除了B,D.因为从句里出现”had forgotten", 主句要选用过去时,答案是A.

我觉得这里没有什么省略。 “better pay” “more people”是并列的,都是工人想要的。不定式“to check British passports after Brexit”作more people 的定语(主谓结构)。工人想要更好的报酬以及脱欧后更多检查英国护照的人员。也可以改成:Workers want better pay, and also want more people to check British pas...
