3、 (that) you can do it.,一定要使用陈述语序。 e.g. He knows what he should do next.,3. 时态：,主句一般现在时，从句据句意用各种时态。 主句一般过去时，从句只能用相应的过去时态。 如宾语从句所陈述的内容是客观真理，客观事实， 自然现象或定理等，则用一般现在时。 e.g. Everyone thinks (that)Milke will win the game. I thought (that )he watched the match. The teacher said (that) the earth goes around t
4、he sun.,注：宾语从句表示不肯定或疑问时，由 whether或if引导，表“是否，是 不是，能否”等。不充当任何句子成 分，只起连接作用，但不能省略。 whether与if引导宾语从句时，一般可通用， 但在下列5种情况下，whether不可换用if：,whether引导的从句居于句首。 2.从句位于介词后作介词宾语。 3.whether在不定式前，与不定式组成词组。 4.主句的谓语动词是discuss等动词。,They are talking about whether he will come here.,I dont know whether to stay or go.,They
5、are discussing whether they should sell the old house.,Whether he agrees with me or not,I dont know.,宾语从句的分类： 1.作动词的宾语： 2.作介词的宾语： 3.作形容词的宾语：,Everyone knows that he is a good student.,This depends on how hard you work.,They are afraid that they are wrong.,say, think, believe, hope, know, understand,
6、suppose等,描写感情的形容词后，如afraid, sure, sorry,glad等,5.从句中有or not时。,I dont know whether or not it rains.,e.g. 他认为他需要拍个X片。 e.g. 我知道我能修理这部车。 e.g. 他们认为他们会有更多的钱。 e.g. 她说她冷,She says that she is cold.,He thinks that he needs an X-ray.,I know that I can repair this car.,They believe that they will have more money
7、.,e.g.我觉得你需要拍个X片。 e.g.听到你生病了我很难过。 e.g.你为我所做的一切我很满意。,I am sure that you need an X-ray.,I am sorry that you are ill.,Im very pleased with what you are doing.,使用宾语从句要注意的3个问题：,1.形式宾语it：如宾语从句后有补语，要用形 式宾语it来代替，而将从句放到补语的后面去。 e.g. He has made it clear that the meeting will not be hold.,2. 宾语从句否定意义的转移：在think
8、、believe、 suppose、except等后的宾语中，如从句谓语是 否定的，一般将not移至主句谓语，而将从句宾语变 为肯定形式。即：否定前移。 e.g. 我想他没时间玩足球。 I think that he doesnt have time to play football.,I dont think that he has time to play football.,3.反意疑问句：宾语从句的主句是主语+think (except,suppose,believe,imagine)时， 附加疑问句部分要根据主句的主语而定：当主语 是第一人称时，要根据从句而定；主语是第二、 三人称时
9、，与主句保持一致，并且要注意否定前移。 e.g. I dont think he is serious,_? You believe she is a good teacher, _?,is he,dont you,巧学宾语从句口诀： 宾语从句三注意，时态、语序、引导词。 主句若是过去时，主从时态要一致。 宾从表达是真理，一般现在就可以。 引导词也不难，陈述可用that连。 一般问句表“是否”，if、whether来引导。 特殊问句作宾从，疑问词引导就能行。 还有一点要说明，陈述语序要记清。,Consolidation,Lets have a test.,类型一：引导词的运用 1 I dont
