关于表两者否定用nor还是or:
表达not A and not B有 两种方式:
I do not like A and B.
I neither like A nor B.
如果要在否定后面再加一个否定的事物,用nor。neither/nor不必须,也可以是not/nor,如:
I do not like action films, nor do I like excessive use of violence in movies.
nor一定表示同时否定2个。not/nor也可能用or 取代nor,变形为not/or,如:
I do not like singing or dancing.
总结:这四种形式都是可以的
I do not like A and B.
I neither like A nor B.
I do not like A nor B.
I do not like A or B.
过去时态
误区:句中确实有完成时标志词until,但是这个是but后面的分句,与前面的句子直接加until还不一样;这里确实出现了过去时间点25年前,前面的句子也确实在25年前之前,但是这个没用过完,因为过去完成时表示leaching是过去的办法,现在不用了,但句中并没有表述这种意识;也就是but后面的句子无关leaching这个主语,基本是无关内容。如果but后面说这个方法leaching 25年前不用了,就不一样。
a well-established method > a method of mineral extraction, well established
there are fewer than one-quarter as many,这里并不是than和as出现在一个比较里,as many在这里是固定词组,表示同样数量的,如:twice as many, one-quarter as many,We visited five countries in as many days。
C选项:pronounced it as中的代词it的指代对象a work,但是这样的指代在语法和逻辑上均是不正确的,由于that literary critic Samuel Johnson, Pope’s contemporary, pronounced the greatest translation in any language是work的定语从句,所以先行词work一定在这个从句中充当成分,应该充当pronounce的宾语,但在本选项中,若pronounce身后有it,则先行词无法在句中充当成分。
如果有修饰成分如比较级,应该放在第一个as前面。例如:We've produced twice as much cotton this year as we did last year.
本题结构为:there are three times as HOUSEHOLD1 as (there are) HOUSEHOLD2. 表示household1是household2的三倍
