二:英语句子的基本结构可以归纳成五种基本句型及其扩大、组合、省略或倒装。
掌握这五种基本句型,是掌握各种英语句子结构的基础。1:
主+谓)2:
主+系+表)3:
主+谓+宾)
主+谓+间宾+直宾)5:
主+谓+宾+宾补)
基本句型一:s
不及物动词) sun │ cares3. what he said │does not matter. 4.
they│talked for half an hour. 5. the pen │writes smoothly
此句型的句子有一个共同特点,即句子的谓语动词。
都能表达完整的意思。这类动词叫做不及物动词,后面可以跟副词、介词短语、状语从句等。
基本句型二:s
v(是系动词)│ 表语) │is │an english-chinese dictionary. dinner │smells │good3. he │fell │in love.
4. everything │looks │different5. he │is growing │tall andstrong.
6. our well │has gone │dry7. his face │turned │red.基本句型。
三:主+谓+宾)
此句型句子的共同特点是:谓语动词都具有实义,都是主语产生的动作,但不能表达完整的意思,必须跟有一个宾语,即动作的承受者,才能使意思完整。这类动词叫做及物动词。
v(及物动词)│ 宾语) │knows │the answer? 2. he│has refused │to help them.
3. he │enjoys │reading. 4.
he │said │\admits │that he was mistaken.
基本句型。四:
oo主+谓+间宾+直宾)
有些及物动词可以有两个宾语。这两个宾语通常一个指人(间接宾语);一个指物(直接宾语)。
v(及物)│ o(多指人)
o(多指物)
│ordered│herself │a new dress. 2. he │brought │you │a dictionary.
3. i │showed│him │my pictures. 4.
i │told │him │that the bus was late. 5. he│showed │me
how to run the machine. 基本句型。
五:主+谓+宾+宾补)
此句型的句子的共同特点是:动词虽然是及物动词,但是只跟一个宾语还不能表达完整的意思,必须加上一个补充成分来补足宾语,才能使意思完整。
v(及物)│o宾语)
c(宾补)
1. they │painted │the door │green. 2.
this │set│them │thinking. 3. they │found │the house │deserted.
4. he │asked│me │to come back soon. 5.
i │saw │them │getting on the bus.三:practice makes perfect.
