单元语法----thesameas&differentfrom

like介词“如,像”

如果两个或两个以上的事物完全相同,可以用thesame来表达;如果不相同,可以用different来表达。

thesame和different可以作表语和定语修饰名词和名词短语等,thesame后,面常接单数名词,而different后常接复数名词。

解析:

like,thesameas和differentfrom

【观察】

1.Thislittledoglookslikeacat.

这只小狗看起来像一只猫。

2.Yourdressisthesameasmine.

你的连衣裙和我的一样。

3.Tom’sinterestisdifferentfromSam’s.Tomlikesplayingsports.

汤姆的兴趣与萨姆的兴趣不同。

汤姆喜欢运动。

Lilyboughtthesameumbrellaasmine.

莉莉和我买了一样的雨伞。

Thistreeisthesameheightasthattree.=Thistreeisastallasthattree.

这棵树和那棵树一样高。

【结论】

说明事物或人之间存在某种程度的相似性,我们常用belike或looklike;说明事物或人完全相同,我们常用thesameas;既不相似也不相同,我们可以用短语bedifferentfrom来表达。

如果表示事物或人之间的相似点,我们也可以用句型thesame+/名词短语+as,thesame…as可与as…as互换。

跟踪练习:

用like,thesame(as),thesame...as,different或differentfrom填空,补全下列句子。

1.Youransweris____________his.Youranswerismoreinterestingthanhis.

2.Hisgiftis____________hisbrother’s.Theyaretwobeautifultoycars.
