2、.He is running fast.2SVP此句中的动词为连系动词，连系动词常用的有be , become等，部分行为动词在某些时候也可以用作 连系动词，如:get, keep , turn , grow等。有些感 官动词也可以作连系动词,Jn：look , sound , taste , smell , feel 等。Trees are green.Mrs. Smith is a doctor.They are interested in P.E.3SV0此句中的动词为及物动词。动词后接宾语时应该用及 物动词若为不及物动词则须在动词后加上合适的介 词。He saw a film.Jim

3、may visit his parents tomorrow.4SVOiOd此句型中的谓语动词是及物动词，后面接两个宾语， 间接宾语一般指人，直接宾语一般指物。一般是主 谓+间宾+直宾，也可以是主谓+直宾十介词+ 间宾。可接双宾语的常见动词有:ask .give .send ,I will give you a book.She bought a present for her parents.buy,sell,bring ,pass ,tell .show ,teach ,promiser 等。5SV0C该句型中的宾语+宾语补足语又叫做复合宾 语，其特点是宾语与其|卜语之间是逻辑上的主谓关

4、系。可接复合宾语的常见动词有：ask , tell, find , help , like , take, make , let, call, watch , see , have 等。The news made everyone happy.He wants me to help him.n.there be 句型there be句型的结构是there be ,某人/某物,某时/某地“，含义是“在某时或某地有某人或某物。 从以上讲解中我们可以初步掌握英语勻子结构的一些特点:英语的句子以谓语为中心，前面是动作的执 行者，后面是动作的承受者。除了基本成分之夕卜，状语也很重要。状语可以位于句首，也

5、可以置于谓语 之后。一般来说，置于句首的多是时间、条件和原因状语，置于谓语之后的是地点、方式、原因、目的、 时间和伴随状语。*过去时和现在諷时的区另di. 时间上有差异一般过去时与现在没有关系，与表示过去的时间状语连用，如:ago Jastyear Just now ,the other day 等。现在完成时与现在有关系，不能与表示过去的时间状语连用。如：He has come back home.（说明现左他在家。）He came back home last year.（只能说明他去年回来过，不能说明他现在在不在家，可能后来又出去 了,但至今未归。）口.结果上有差异现在完成时和一般过去时

6、都表示在过去完成的动作，现在完成时强调对“现在“的影响和结果，动作到 现在刚完成或还在继续。一般过去时强调动作发生在“过去，和现在没有关系。【活学活用】1） She the piano for six years , but she doesn* t play now.A. have playedB.playedC.has played答案:B从后半句可以判断她我不再弹钢琴了，说明前面的动作和现在已经没有关系，只是单纯地 陈述过去的事情，所以用一般过去时。2 ) We the museum yesterday.A. visitedB.visitC.have visited答案:A有明显的过去时

7、间状语yesterday ,可以判断用一般过去时。3 ) I stamps since I was ten years old. A. collected B.have collected C.am collecting答案:B since 自从.“是现在完成时的一个标志性词语，表示动作从某时开始一直延续，所以用 现在完成时。4) I to school yesterday because I was ill.A. wentB.haven* t gone C.didn, t go答案:C全句为因果关系，应该是.生病没有上学“，所以否定A项；陈述昨天的事情，没提到和现在 的关系，所以应用一般过去

8、时。5 ) I in Beijing for ten years.A. livedB.have livedC.has lived答案:B句意为“我住在北京我十年了,没有任何其他提示，表朝在仍住在北京。典题瞬经典例题在对话的空格处填上适当的单词，使对1舌完整、正确，每空一I司。A: Mum , which TV program借目）are you 1 ?B:Oh , I, m watching a Beijing Opera.A: Is that 2 interesting than a football game?B:Yes , I think 3 .1 prefer（更喜欢a Beijing

10、 right.思路蜥：1. 从下文问话“我正在看京剧“中可以看出，上句话中问的是“看什么。答案:watching2. 从后面的than可以看岀这是一个比较级，因为interesting是个多音节形容词。答案:more3. 从答语yes ,可以看出是肯定的形武。答案:so4. prefer.to.喜欢.胜过. 答案:to5. 提出建议“我们来看卡通片而不要看京剧和球寒“，要用一个词表达此意。答案:instead6. 从末尾的介词on判断，最爰的电视节目在哪使道。答案:channel 7. 上演或是播出,但注意主语是it,所以应用被动语蕊 答案:showed8. not.anything=noth

11、ingo 答案:anything9. must后面要接动词原形，be on channel 6 在6频道。答案:be10. just暗示本句应该是现在完成时。答案:has黑色陷阱：本题有两处陷阱，一是第6题，如果注意不到后面的介词on,很容易理解成你最喜欢什么电视节目，而本题是最喜欢的节目在哪使道，所以要填channel而不是program。第二处是第7 题，很容易让人凭直觉填be，说明卡通节目在第丿濒道，陷阱是前面我有be动词is 了。所以填be不 对，并且还要注意动词的被动语态的运用。绿色通道：解答此类题一定要先通读全文，对对话的主要内容有一个大槪的理解，并充分利用好上下文所提供的信息，注

15、。3. F收集洋娃娃不是一个锻炼体能的爰好，所以不能使人变强壮。4. T从文中的例子可以看出踢足球能使人理解团队合作的重要性，所以应该是一项团队运动。5.
