1） Often it is the delivery which causes the audience to smile ,so speak slowly and remember that a raised eyebrow or an unbelieving look may help to show that you are making a light-hearted remark.
這是一個強調(diào)句型.
It is + 被強調(diào)部分 + which (that,who,whom) 表示：正是,就是.
例如：
It is him whom they are talking about.
他們在談到的正是他.
實際這句話應(yīng)這樣：
They are talking about him.
第一句應(yīng)是這樣：
The delivery causes the audience to smile
所以：主語是 The delivery
謂語是 causes
賓語是 the audience to smile
為強調(diào)主語The delivery,所以用了It is + 被強調(diào)部分 + which 句型.
其后的部分是進(jìn)一步說明整個句子的,做狀語.
其實這是一句從句,但省略了泛指的主語“你”而只有謂語speak slowly and remember
remember后帶有自己的賓語從句a raised eyebrow or an unbelieving look may help to show that you are making a light-hearted remark.
另外,賓語從句中的謂語show 還帶有自己的從句.
此句比較復(fù)雜,從句套從句.
2）A twist on a familiar quote "If at first you don’t succeed, give up" or a play on words or on situation.
這不是一個句子,只是一個短語 .沒有主語,謂語,賓語.短語中有一個引語.
如果你想搞明白引語的意思,只分析引語就行.而這里引語也只是斷章取意,只有一個if 從句,不是整個句子.
