动词原形+其他
Standup,please.=Pleasestandup.Lookattheblackboard.
(2)be型:

3.祈使句的回答祈使句的动作通常是表示将来发生的动作,所以回答祈使句时,一般用will或won’t。
(单项情景交际)
在回答具有否定意义的祈使句时,要注意两点:
1)形式一致(即Yes与will保持一致;
No与won’t保持一致)
2)事实一致(回答时,要注意分析上下文语境中所提供的条件)
Eg:
---Don’tgoout,please.It’srainingheavilyoutside.
----Yes,Iwill.Ihavetomeetmybrotherattheairport.(不)
三.现在完成时

1.现在完成时的定义:
现在完成时表示动作发生在过去,但与现在情况有联系有影响,即用一个发生在过去的动作来说明现在的情况。
2、现在完成时的谓语构成:
助动词have/has+动词的过去分词
3、常用时间状语:
(1)与包括“现在”在内的时间状语连用,如:
bynow(到现在为止),sofar(迄今为止),thesedays(这些天来),thisyear,thismonth,today,inthepastfewyears(在过去的几年以来)等;
e.g.Wehaveplantedmanyflowersthisyear.
Chinahaschangedalotinthepastfewyears.
Ihavelearnedtwothousandwordssofar(bynow).
Ithasrainedthesedays.
(2)与副词连用,如:
just,before,already,never,ever,yet,
Recently,since,for等

Thenewbookhavenotarrivedyet.
Haveyouheardfromhimyet?
Theyhavealreadyfinishedtheirhomework.

“干了/干过某事”
e.g.Ihavefinishedmywork.
Shehasreadallthesebooks.
ThemanhaslivedinChina.

3.Wehavelivedinthisstreet_____1975.
4.Hisdaughterhasbeenabroad_____ayearandhalf.
四.一般现在时
A一般现在时通常用来描述:
1现在的事实。
2经常发生的动作。
3真理、基本事实或常见现象。

B一般现在时表示现在在内的一段时间经常反复发生的动作或存在的状态。
be动词有am,is,are三种形式,“有”动词有have和has两种形式。
其他动词在一般现在时里用原形,但主语是第三人称单数时,动词词尾要加“s”或“es”。
行为动词一般现在时的基本结构:
肯定句:
主语+谓语
否定句:
主语+do(es)n’t+动词原形
一般疑问句:
Do(es)+主语+动词原形
