i am sure he is not such a man as (这个是定语从句的引导词可以替换成who)would leave his work half done
as 这个表示原因many instruments (as are in the lab )括起来的部分是个定语从句,修饰instruments,千万要理解成as...as结构。have been made most use of
希望你看明白了
such sth as下述一类的; (像后面提及的)那样的, 这样的, 如此的
Such a disaster as her car being stolen had never happened before.
有的祸事, 像她的汽车被盗之类, 以前从未发生过.
as...as
达到与...相同的程度; 与...等同
as tall as his father 和他父亲一样高 * This dress is twice as expensive as that. 这件连衣裙比那件贵一倍. * He doesn't play half as well as his sister. 他演奏的水平不及他姐姐的一半.
as...as...中的第一个as是副词, 后接形容词或副词的原级, 或接形容词再接名词;第二个as是连词,后接从句
例如
She is as tall as I.
She writes as carefully as I.
She has as many books as I.
i am sure he is not such a man as would leave his work half done
such +名词+as 这是一个定语从句,我确信他不是一个会半途而废的那种人。
as many instruments as are in the lab have been made most use of
as+名词+as也是一个定语从句,试验室里有很多的器材被成分利用。
