? Whether he will e is uncertain. / it is uncertain whether / if he will e. ? ⑶ . 名詞性關系詞引導 ? 由名詞性關系詞引導的主語從句一般位于句首, ? Examples。 ? ① 難的是一輩子做好事,不做壞事。 ? ③ 據說如果交通運輸技術也像計算機那樣飛速發(fā)展的話,今天人們跨越大西洋就只需幾秒鐘了。 ? ? 起賓語作用的名詞性從句叫做賓語從句。賓語從句一般置于謂語動詞后,但也可作某些介詞與某些具有動作意義的形容如 afraid, sure, aware, certain等的賓語。 ? Example: ? We know foreign languages are useful tools in research work. ? 在帶有賓語補足語的句子中,往往用 it 作形式賓語,而將 that從句置于句末作邏輯賓語,表達具體內容。 ? Examples: ? We will answer for it that the product is of extra superior quality. ? You may depend on it that she is qualified for the task. ? ⑵ . 由 wh疑問詞引導 ? Examples: ? Most people know what it is like to have their blood pressure taken, but few people understand the meaning of the numbers used to record blood pressure. ? Progress depends primarily on whether the individual makes the effort. ? 注意 : whether, if 都可以引導賓語從句,二者的區(qū)別在于:whether 引導的賓語從句可以做介詞賓語,而 if則不能。在英語中,只有五個介詞后面可跟 that從句,它們是 except, in, but, besides, save. ? Examples: ? Living things are different from nonliving things in that the former perform life functions and the latter do not. ? I don’t know his address except that it was Leadenhall Street. ? I agree with you, save that you have got some facts wrong. ? They believed that land did not belong to people, but that people belong to land. ? Excises: ? 用賓語從句完成下列句子。 ? ② ________________(從以上所說的 ) it can be seen that practice is the key to mastery of a foreign language. ? ③ They gave___________(來校的人 ) a warm wel
