理工類職稱英語考試語法學習筆記
條件狀語從句:分真實條件句和非真實條件句
重點:在條件狀語中,用一般時代替將來時
虛擬語氣
主要連接詞:
if / unless
例如:
Children should not be taken into the room of a very sick person ______ there is some special reason for it.
A.except B. besides C. unlessD.whereas
解題思路:根據上面說過的連接原則,這里必須是一個連接詞,而A,B都是介詞,因此正確答案只能在C,D中選。whereas意為而,故正確答案為C.
provided / on condition that 知道這也是連接詞就可以了,一般說,當考題中出現這種詞時,應傾向選擇。
3) 原因狀語從句:
主要連接詞:because/ since / as
要點:不要把連接詞 because與介詞短語because of 相混淆;
不要把表示原因的since與表示時間的since自從相混淆;
不要把表示原因的as與表示時間的as隨著相混淆;
順便提一下, because表示直接因果關系,而since, as 是對事實的說明,主句和從句之間并不一定具有因果關系.
例如:
As you are already 18 years old, you should know what to do and what not to do.
這個句子用because連接就不太合適。好在軍隊職稱考試中并不要求作這種分辨。
for 注意:一般只能放在主句后面,即主句 + for從句,例如:
He must have gone to bed, for it is too late. 該句不能用because
now that / seeing that / considering that
Seeing that this problem was settled, they proceeded to the next one.
in that一般放在主句后面,例如:
Humans are superior to animals in that they can use languages as a tool to communicate.
