She doesn’t know (that) she is seriously ill. I am sure (that) he will succeed.that 的省略:. I guess (that) somebody else has borrowed it.注意:當(dāng)主句謂語動(dòng)詞帶有兩個(gè)或兩個(gè)以上賓語從句時(shí),可以省略第一個(gè)that,其他不能省略。if/ whether “是否”,說明對陳述的事物不明確或不清楚。 下列情況用whether, 主表不定式or (not)。 賓語從句若否定,whether一詞不可用。主句是I/We think/suppose/guess/believe等時(shí),從句中的否定習(xí)慣上要轉(zhuǎn)移到主句中。從句若表否定意,否定詞語要前移。I know he lives here . I know he lived here ten years ago . I have heard that he will e tomorrow .(一般過去時(shí),過去進(jìn)行時(shí)),從句的時(shí)態(tài)一定要用相對應(yīng)的過去的某種時(shí)態(tài)(一般過去時(shí),過去進(jìn)行時(shí),過去將來時(shí),過去完成時(shí))I knew who lived there.
