Question

10．可以肯定的是，他的決定基于父母的幫助和支持．
It wascertain （that） his decision was based on his parents'help and support．

Answer 1

分析 certain （that） his decision was based．

解答 答案：certain （that） his decision was based．結(jié)合中英文，這里是應(yīng)it作為形式主語，that從句作為真正主語，構(gòu)成句型it is certain that，表示毫無疑問…肯定…，這里是一般過去時，故it was certain that，that可以省略，從句也用一般過去時，表示基于…用be based on，主語是他的決定his decision單數(shù)，故用was based on，故答案是certain （that） his decision was based．

點評 It+be+形容詞+that-從句的句型有：It is necessary that-有必要--It is important that-重要的是--It is obvious that-很明顯--b．It+be+-ed 分詞+that-從句 It is believed that-人們相信--It is known to all that-從所周知
