Verbs with actual meaning can be used as “Verb” in a sentence. Auxiliary verbs alone cannot be used as “Verb” in a sentence.III Learn to recognize the sentence structures.1. SV structure. For Example:(1) A bird flies.S V(2) A monkey jumps.S V(3) A fish swims.S V√ In SV structures, verbs are “intransitive verbs”.2. SVO structure. For Example:(1) A sheep eats grass.S V O(2) They like bananas.S V O(3) He wants candy.S V O√ In SVO structures, verbs are “transitive verbs”.3. SP structure. For Example:(1) This is great.S P (2) He looks well.S P (3) She became a teacher.S P √ In SP structures, Predicatives are formed by “link verbs” and “adjectives or nouns”.√ link verbs: be, become, grow, look, feel, taste, etc.4.

常跟双宾语的动词有:(需借助to的)bring, ask, hand, offer, give, lend, send, show, teach, tell, write, pass, pay, promise, return等;基本句型 五S +V + O + OC(主+谓+宾+宾补)特点: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。 判断原则:能表达成—宾语 是…/做…注:此结构由“主语+及物的谓语动词+宾语+宾语补足语”构成。宾语与宾语补足语之间有逻辑上的主谓关系或主表关系,若无宾语补足语,则句意不够完整。可以用做宾补的有:名词,形容词,副词,介词短语,动词不定式,分词等。如:He considers himself an expert on the subject.他认为自己是这门学科的专家。We must keep our classroom clean.我们必须保持教室清洁。I had my bike stolen.我的自行车被偷了。We invited him to come to our school.我们邀请他来我们学校。I beg you to keep secret what we talked here.我求你对这里所谈的话保密。用it做形式宾语,而将真正的宾语放到宾语补足语的后面,以使句子结构平衡,是英语常用的句型结构方式。即:主语+谓语+it+宾补+真正宾语。如:We think it a good idea to go climb the mountain this Sunday.
