can

tell

that

Lisa

really

wanted

to

win,

though.

但是你能看得出丽萨真地很想赢。

win与beat的用法区别。单词释

义过去式用

法win赢得；获胜won后接match，war，prize等名词。beat赢；战胜beat后接竞争对手（人或团体）的名词或代词。

例如:

They

won

the

volleyball

match.

他们赢得了排球赛。

We

beat

them

by

3

to

1.

我们以3比1赢了他们。6.Areyouasfriendlyasyoursister你和你的妹妹一样友好吗？DoesTaraworkashardasTina塔拉和蒂娜工作一样努力吗？

“as…as”意为“和……一样”，用于形容词、副词的同级比较。此结构中两个as的词性和用法不一样：第一个as是副词，后面接形容词或副词的原级，第二个as为连词。“as…as”的否定式为“not

as/so+形容词/副词的原级+as”，表示“不如……”，其中，第一个as可以用副词so替换，但第二个as则不能。

（1）表示两者程度相同时，用“A

+

be/实义动词+as

+形容词/副词的原级+as

+B.”。例如:

This

movie

is

as

interesting

as

that

one.

这部电影和那部电影一样有趣。

Linda

studies

as

hard

as

Helen.

琳达和海伦学习一样努力。（2）表示一方和另一方不一样时，用“A+

be/实义动词+not+as/so+形容词/副词的原级+

as+B.

”。【注意】“as/so+形容词/副词的原级+as”只能用在否定句中。例如:

Eric

isn’t

as/

so

strong

as

Frank.

埃里克不如弗兰克强壮。

Cindy

doesn’t

jump

as/

so

high

as

Betty.

辛迪跳得不如贝蒂高。基础达标一、单项选择。1.Sally’s
