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.to

sb.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。

over强调在某物的正上方，两物体之间有一定距离，与under相对。
