1.主句是一般现在时,从句可以为各种时态。
2.主句是一般过去时,从句要用相应过去时态。
注意:从句描绘客观事实、真理、自然现象等,从句时态不受主句时态限制,仍用一般现在时。
例句:He answered that he was listening to me.
Father told me that practice makes perfect .
“形容词短语”省略的理由和方式,与“分词短语”作后置定语一样。当它们不是句中的重点信息,就可以去掉关系代词和be动词。形容词作后置定语同定语从句一样,可以分为“限制性”和“非限制性”。
例1:I bought this comic book hot off the press. 我买了这本刚刚出版的漫画书。
例2:She is a kind lady, ready to help others. 她是一个善良的女人, 总是帮助别人。
例3:Companies large and small the world over have been developing their own “corporate universities”. 全世界大大小小的公司都一直在办自己的“公司大学”。
陈述句语序,就是主语在前,谓语动词在后。
错误: He is wondering when can he finish this difficult job.
正确: He is wondering when he can finish this difficult job.
注意:宾语从句的否定转移
主句的谓语动词是think,believe,imagine,suppose,consider,expect,fancy,guess等,并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致.例如; I don’t think he will come to my party.而不能说成I think he won’t come to my party.
同上面一样,At基本上后接sound,sight“听到、看到”之类的词;on接“回来、到达”之类的词;用in,during表示“when, while”;用over表示“while”之意。当然,这一切都是相对的分类。
