很多人询问新加坡AEIS考试试题难吗?新加坡AEIS报名时间是什么时候?到底要不要参加新加坡AEIS考前培训班培训班?国内AEIS考试培训机构提醒:只要进行科学的培训,并注意日常点滴的积累,通过考试并不难。很多人通过AEIS考试线上培训顺利的去新加坡留学,今天AEIS中国培训基地老师为大家介绍形容词从句的位置。
形容词从句总是跟在被修饰的名词(即先行词)后面。例如:
① Any change which causes the formation of new matters is a chemical change.(在主句主语的名词之后)
② Plastics is an important material which is widely used in industry.(在主句补足语名词之后)
③ It has certain features that are easily recognised.(在主句宾语名词之后)
深圳AEIS考试培训解析形容词从句的位置在下列情况下,形容词从句和所修饰的名词隔开:
㈠被介词短语隔开,如:
④ Magnets work through lines of force that extend between the two ends of the magnet.
⑤ A molecule may be defined as the smallest particle of matter that can exist without changing its nature.
④里的形容词从句和先行词“lines”被介词短语“of force” 分离。⑤里的却被另一个介词短语“of matter”隔开。

㈡被分词短语隔开,如:
⑥ There is no method known to medical science today that can effectively cure cancer.
⑥里的形容词从句和先行词“method”之间被过去分词短语“ known to medical science today”隔开。
上述两种隔离情况可以理解,也被接受。
另外还有一种分隔情况,也偶尔见到,特别在科技英语中,但这种离异法,值得商榷。
例如:
⑦ Several other ideas came along that enabled engineers to design still smaller units.
⑧ Ninety-six substances are known which chemists consider to be elements.
⑦和⑧里的形容词从句和先行词“ideas”及“substances”之间都被主句的谓语动词“came along”和“are known”分开。
这类的分隔情况,多在主句谓语动词是被动语态(the passive voice)时才出现,如例⑧,但谓语动词是主动语态(the active voice)的话,也可以,如例⑦,只是数量少些。
为什么要把形容词从句常见的位置和先行词分开呢?主要原因是:先行词所在的主句较短,而修饰先行词的形容词从句则很长。为了平衡主句和从句,才采用这方法。虽然如此,但它和一般的形容词从句的位置有很多抵触,恐怕引起混乱。
为了减少不必要的麻烦,最好改用别的句式。其中一个方法是将形容词从句改为另外一个独立的简单句(如例⑨);另一个办法是采用并列句(如例⑩):
⑨ Several other ideas came along. Such ideas /They enabled engineers to design still small units.
⑩ Several other ideas came along and these ideas enabled engineers to design still small units.
Ninety-six substances are known. Chemists consider them to be elements.
Ninety-six substances are known and chemists consider them to be elements.
