1. a pair f...
后跟可数名词的复数形式。其中 pair 用作可数名词,意为“一对,一双”,常与介词f连用,表示裤子、鞋子、袜子、眼镜、手套等由两个相同部分组成的物品的数量。 pair(s) f后接名词作主语时谓语动词的数应根据 pair 的单复数来确定。① “ f+复数名词”作主语时，谓语动词用单数。A pair f shes here is 50 yuan.在这里一双鞋要 50 元。② “ f+复数名词”作主语时,谓语动词用复数。These tw pairs f shes are 100 yuan.这两双鞋 100 元。
① 实义动词 需要此时need作谓语,变否定句、一般疑问句或特殊疑问句须借助助动词 d/des。need sth. 需要某物→I need achair. 我需要一把椅子。need t d sth.需要做某事→We need t eat healthy fd.我们需要吃健康的食物。② 情态动词 需要没有人称和数的变化,后跟动词原形一般用于疑问句或否定句中。以must开头的一般疑问句的否定回答常用needn't(不需要;没必要)。—Need we g s early? 我们需要这么早去吗？—Sure.当然。—Must I d it nw? 我必须现在就做(这件事)吗?—N, yu needn't. Yu can d it next week. 不,不需要。你可以下周做。
3. keep sb./sth.+宾补
该结构中的宾补可由形容词、副词、动词 -ing 形式或介词短语充当。该句中的形容词 tidy 用作宾补,说明你的房间状态。They need t keep the classrm clean.他们需要保持教室干净。(形容词clean作宾补)Dn't keep Tm waiting there.不要让汤姆一直在那里等。(动词-ing形式waiting作宾补)
英语中表示人或物的位置时,通常要借助方位介词。方位介词不能单独使用，通常和后面的名词或代词构成介词短语。即: 方位介词(in/n/under/...)+定冠词the 或形容词性物主代词等+名词。
4. 方位介词 in,n与 under 的用法
(1) 表示“在……中,在……里”指在某个空间的内部。in ur class 在我们班里in my bag 在我的包里(2) n表示“在……上”通常指一个人或物在另一个物体的上面,两者之间有接触面。n the wall 在墙上n the flr在(室内)地板上(3) under表示“在…下”,常指一个人或物在另一个物体的正下方,两者之间可能有空隙,也可能接触着,或一物为另一物所覆盖。under the chair 在椅子下面under the tree 在树下
