比一比(找错误)
He told me (that) Summer is after Spring .
not . 看一看：
will rain
rains
I don’t know if it -------tomorrow. If it ----,I’ll
stay at home. (rain )
will come
comes
I want to know when he ___back. When he -
Jim will cook ( cook ) dinner tomorrow . Jim is singing ( sing )a popular song now.
Jim has been ( be ) to the Great Wall twice . Jim was playing ( play ) basketball when his

二.宾语从句中时态的变化
填一填
I hear (that)
Jim was ( be ) a worker two years ago. Jim is ( be ) an English teacher now .
2. I don’t care of ______ he is handsome. 介词后只能用whether
3. He wondered ______ to stay here the next week. 与to do 不定式连用只能用whether
-- back, please tell me.(come) would buy If I had lots of money,I ____(buy) a big house
for mother.
想一想：when和if 可以引导什么从句？它们的时态有什么特
点？
If 与whether 的区别
1. I don’t know _____ he will come or not. 与or not 连用只能用whether
He said
1) He would go to Hong Kong . 2) He was sick. 3) He was reading a book . 4) He had finished his work.
2.当主句是一般过去时的时候，宾语从句必须运用相 应的过去的某一种时态，从而达到主句和从句的相互 一致。（呼应性原则）
三 .宾语从句的引导词
1.由从属连词that引导的宾语从句（think，believe，guess等
e.g. I hear (that) he will be back in an hour.
注：that 在句中无词义，在从句中不能充 当句子成分，在口语中往往被省略。
２.由从属连词 whether, if 引导的宾语从句
father came back. Jim had learned ( learn )1000 Chinese words
by the end of last semester.
1.当主句是一般现在时，宾语从句的时态不作限制， 我们可以根据句子的需要使用任何一种时态。 （需要性原则）
辨一辨
1) He will go to Hong Kong . 2) He is sick. 3) He is reading a book . 4) He has finished his work.
