知識點講解:

1.If you don't think…
賓語從句的否定轉移
主句的謂語動詞是think,believe,imagine,suppose,consider,espect,fancy,guess等,并且主句的主語是第一人稱而且為一般現在時,從句的否定詞一般要轉移到主句上來,其反義疑問句一般與賓語從句一致.
I don’t think he will come to my party.而不能說成I think he won’t come to my party.
我認為他不會來我的舞會.
I don’t believe that man is killed by Jim,is he?
我認為那個人不是Jim所殺的,是不是?
如果賓語從句中有某個含有否定意義的形容詞或副詞,其反義疑問句要用肯定形式.
We find that he never listens to the teacher carefully,does he?
我們發現他從來不仔細聽老師講課,是不是?

2.worth
adj.值得的；有……的價值；等值的；有……的財產
n.財富，財產；價值
eg:The professor's discovery was of great worth. 這位教授的發現很有價值。
