1。ought to have done=should have done本來應該做而沒有作 must have done 表示對過去情況的肯定猜測，might have done表示對過去情況的猜測，但是語氣很弱need have done表示需要做而沒有做，從題目的意思來看，珍妮本來應該現在就在這里，我想知道她沒來究竟發生了什么事，所以答案選b2。 ,absolutely，完全地，絕對的 ,徑直地，坦率的，我們邀請他參加聚會，但是他卻拒絕的了3、remaining 剩余的，剩下的，做前置定語，而left 作后置定語The lady said she would buy a gift for her daughter with the remaining 20dollars/with 20 dollars left4。我們可以把它變成一般的陳述句，然后再進行感嘆句的變換life today is different from ____was 50years ago很顯然這里需要的是名詞性從句what was 50 years ago ，what 做was 得主語同時引導名詞性從句作from 的賓語，然而how 不能作主語，只能引導狀語，所以排除所以把它變成感嘆句，強調50年前和現在生活的不同，既然是強調different ,所以要用how ,所以就變成了How diffferent life today is what was 50 years ago。

第3題是很難啊 是不是THE的緣故啊 我猜的啊

熱心網友

1.ought to have done表示本應該做而沒做。 mply有真誠的的意思，directly太不禮貌了3.不會解釋，我是靠語感。4.你把它變成陳述句Life today is different from ...因為修飾different而不是名詞所以前面用how，后面是代詞所以用what
