(1)happenvi(偶然地)发生；出现Pagel1.line2andpage12.1ine5

辨析：happen,befall,occur,takeplace与comeabout

happen,occur,befall,takeplace,comeabout五词都有“发生”之意，但有区别。

happen使用最广，有偶然发生之意。

Befall指灾祸等的发生或出现。多用于书面语，并且往往暗示命运的作用。

occur用法较正式，既可以指自然发生，也可以指有意安排。可用于具体的事物，也可用于

抽象的事物。用于指具体事物时，可与happen互换（但happen后接不定式时，不能与occur

互换。该词有“想起”的意思，这时不可同happen互换

takeplace常可与happen,occur互换（以具体事物作主语时），但较多地指有计划，按事先

安排的进行的含义。引申用法可表示举行、进行的意思。

comeabout往往注重事情发生的原因，常与how连用。

注：以上五词均为不及物动词，无被动语态。

⑵disturbing(page12linc2)烦扰的

Step2.Grammarpoint

1.概说

英语里同位语也是一种名词修饰语，单词、短语和从句都可用作同位语，最简单而又常见的

同位语是位于所修饰的先行词之后，用来说明身份、职务、称号
