Step7.Reading

Readthedialogueandunderstandthelanguagepoints.

1.Wouldyoulikesomemarkers?

你想要一些水彩笔吗?

(1)wouldlike意为“想要”,无人称和数的变化,后面接名词或代词,表示具体想要某样东西。

would在此句型中表示委婉语气,不是will的过去式。

如:

I'dliketwosweatersformydaughters.我想给我的女儿们买两件毛衣。

(2)对于Wouldyouliketo...?

提出的建议或要求,肯定回答常用“Yes,please.”或“Yes,Iwouldlove/liketo.”;否定回答常用“No,thanks.”。

2.Thebudsgrowintoflowers.这些芽已长成花(骨朵)了。

grow当不及物动词时,表示“种植,生长,增长”。

当及物动词讲时,意思是“种植,栽培”。

如:

Whatdoyougrowinthefield?

在这块地里你们种植什么?

Myparentsgrowriceandwheatonourfarm.我父母在农场上种稻子和小麦。

3.Doyouneedaruler?

你需要一把尺子吗?

(1)need在这里作实义动词,后接名词或动词不定式,即needsth.意为“需要某物”;needtodosth.意为“需要做某事”。

构成否定句和疑问句时,要借助助动词do。

如:

Hedoesn'tneedtoseeadoctor.他不必看医生。

(2)need也可作情态动词,后接动词原形,但常用于否定句和疑问句中。

如:

Youneedn'twritedownthewords.你不用写下这些单词。

辨析1.borrowvs.lend

这两个词都有“借”的意思,但是二者有区别。

(1)borrow是“借来”的意思,构成短语borrowsth.fromsb.,常指从别人那借进什么东西。

如:

Iborrowedastory-bookfrommyfriend.我从朋友那借来一本故事书。

(2)lend则是“借出”的意思,把自己所拥有的东西借给别人。

构成短语lendsth.tosb.或lendsb.sth.。

lend是不规则动词,过去式和过去分词为:

lent,lent。

如:

Myclassmatelentherstory-booktome.我的同学把她的故事书借给了我。

Coveryourseedwithsoil.用土将种子盖上。

2.withvs.in两者都有“用”之意,with强调使用工具,in表示所用的材料或颜料,另外用某种语言说或写用in而不用with。

Writewithapencil.用铅笔写。

SpeakinEnglish.用英语讲。

Putyourposteraboveyourpot.把你的海报挂在盆子上方。

3.above,over,on

above强调高于某物,与below相对。

above也可表示度数及山岳的海拔高度,over与on都不能。

Thereisalightabovethetable.在桌子上方有一盏灯。

Theboy’sbodytemperatureisabove38℃.那孩子的体温在摄氏38度以上。
