一診斷測評

行為（白天）小唾專心于效果

有規(guī)律的數(shù)量______________平均的數(shù)字

商量：討論度過：通過同意

放棄太多熬夜與...…不同

對..有影響另——方-面和...一樣好

閑逛例如過去常常做某事

持續(xù)做某事盡力做某事允許某人做某事

二重難點把握

動詞不定式的用法

1.構(gòu)成：to+動詞原形，無人稱和數(shù)的變化

2.作主語（1）位于句首，謂語動詞用單數(shù)形式

Toseeistobelieve._________________

Togettherebybuswilltakeushalfanhour.

（2）用it作形式主語，把真正的主語一動詞不定式置于句子后部

[t'sourdutytotakegoodcareofthechildren.

Itiseasyforus（finish）writingthecompositioninaquarter.

3.作賓語Wehopetogettherebeforedark.

拓展：跟動詞不定式作賓語的常用動詞有：agree>decide>expect>fail、hope>manage>offer>

plan>prepare>pretend、refuse>want、wish。

當(dāng)復(fù)合賓語中的賓語是動詞不定式時，先用形式賓語it代替動詞不定式，把動詞不定式置于

賓語補足語之后，即主語+動詞+it+賓語補足語+todosth.

Wethinkitimportanttolearnaforeignlanguagewell.

4.作賓語補足語Myparentswillnotallowmetoplayonthestreet.

拓展：有的動詞在主動語態(tài)中用不帶to的動詞不定式作賓語補足語，但在被動語態(tài)中要將to

還原。這些動詞有：feel、hear^make、have>see>watch>noticeo

5.作表語Mypurposeistopointoutthedifficultiesofthematter.我的目的是指出這件事的難處。

6.作定語ThenexttraintoarriveisfromShanghai.Doyouhaveanythingtoeat?

7.作狀語Icomeheretosaygood-byetoyou.（目的狀語）

Hehurriedtothestationonlytofindthatthetrainhadleft.（結(jié)果狀語）

I'mgladtoseeyou.（原因狀語）
