Unit5 Canada-“The True North”-grammar學案
we discussed whether we should hold a meeting. 我們討論了是否要開一個會。 3. that ,why 與 because的用法區(qū)別它們在引導表語從句中很容易混淆,區(qū)別于下:(1) 當主語是reason(原因)時,后面的表語從句的引導詞通常用that:the reason why he didn’t attend the party yesterday is that he hasn’t come back yet. 他昨天沒有參加聚會是因為他還沒有回來。【注】在現(xiàn)代英語中,有時也用 because,但不如用 that 普通。(2) why和 because 都可引導表語從句,但前者強調(diào)結果,后者強調(diào)的原因:i had neither a raincoat nor an umbrella. that’s why i got wet all through. 我既沒穿雨衣,也沒帶雨傘,所以全身都淋濕了。i got wet all through. that’s because i had neither a raincoat nor an umbrella. 我全身都淋濕了,因為我既沒穿雨衣,也沒帶雨傘4. that 與 whether (if)的用法區(qū)別從意思上看,兩者不應該發(fā)生混淆,因為 whether (if) 表示“是否”,而that 卻不表示任何含義,但實際使用時,有的同學卻經(jīng)常將其用混,并且各類語法考試也常考查它。兩者的原則區(qū)別是:that 表示一種肯定、明確的概念,而 whether (if) 則表示一種不肯定、不明確的概念。請看幾道考題:(1)______ the olympic games will be held in beijing is not known yet. a. that b. ifc. whether d. whenever [選c](2)______ we’ll go camping tomorrow depends on the weather. a. if b. whetherc. that d. where [選b]
