考点突破
考点1: The internet has brought big changes to everyday life.
互联网给日常生活带来了巨大的变化。
①bring: v. 带来 (bring-brought-brought)
bring big changes to 给……带来重大变化
【bring的基本用法】
bring sb. sth.= bring sth. to sb. 把某物带给某人
Example: This song brought us much joy. 这首歌给我们带来了许多欢乐。= This song brought much joy to us.
考点突破
辨析everyday 和 every day
①every day 是副词短语,意思是“每天”,表示频率,通常用作句子的时间 状语。
Example: I go to school on foot every day. 我每天步行去上学。
②everyday 是形容词意思是“日常的,每天的”,同义词为daily。仅用在名词之前作定语,不能单独使用。
Example: The Internet has become part of everyday life.
互联网已成为日常生活的一部分。
【详解】由中英文对比可知,缺少“给……带来好运”;bring“带来”,bring sth. to sb.“给某人带来某物”;good luck“好运”;can为情态动词,后接动词原形。故填bring good luck to。
1.在中国,人们相信红色能给人们带来好运。
People believed that red can them in China.
bring good luck to
考点突破
考点2: Take health for example. 以健康为例。
take... for example:以……为例= take... as an example
【example 的其他短语】
1. for example含义:例如(用于列举具体事例支撑观点)。
Example: For example, smart rubbish bins will automatically tell the smart city network when they are full.
例如,智能垃圾桶将自动告诉智慧城市网络它们已满。

4. take... as an example 以…...为例(引出具体案例说明观点)。
Example: Take solar energy as an example, it’s a clean resource that reduces reliance on fossil fuels.(以太阳能为例)
【详解】结合中英文提示可知,此处缺少take sth for example“以...…为例”,句子是祈使句,动词用原形,故填Take;for.
1. 以这本书为例,我们可以从中学到很多历史知识。(完成译句)
this book example, and we can learn much knowledge about history from it.
2. There are a lot of ways to protect the environment. ________, we can take our own bags instead of asking for plastic bags when shopping.
Take
for
A. By the way B. In general C. For example D. To our surprise
【详解】句意:有很多方法可以保护环境。例如,我们可以自己带袋子,而不是在购物时要塑料袋。考查介词短语。By the way顺便说一下;In general总的来说;For example例如;To our surprise令我们惊讶的是。根据“we can take our own bags instead of asking for plastic bags when shopping.”可知购物时自带购物袋,这是保护环境的例子,故选C。
C

A. not trust B. don’t trust C. not to trust D. to not trust
2. 昨天,我朋友提醒我面试的时间。
Yesterday, my friend me the time of the interview.
C

考点突破
②辨析because和because of
1. because
(1)含义:“because”是一个连词,用来引导原因状语从句,表示“因为…”。
(2)用法:引导原因状语从句:后面接一个完整的句子(主语+谓语)。
He didn't come to the party because he was sick.他没有来参加派对,因为他生病了。
注意:不能与“so”连用:在英语中,“because”和“so”不能同时出现在一个句子中,因为它们都表示因果关系。
考点突破
2. because of
(1)含义:because of是一个介词短语,用来表示“因为……”,后面接名词、代词、动名词等名词性成分。
(2)用法:后面接名词或名词性短语:不能引导完整的句子。
He didn't come to the party because of his illness.
他因病没来参加聚会。
可以用于句子的开头或中间:在句子中可以灵活使用。

The match was postponed because of the heavy rain. 比赛被推迟了,因为大雨。
【详解】句意:——由于糟糕的天气,男孩没来上学。——不是,他没来是因为他生病了。
考查because与because of的用法区别。because of后接名词性短语,而because后接句子。第一空后的“the bad weather”是名词性短语,因此用because of;第二空后的“he was ill”是一个句子,因此用because。故选A。
—The boy didn’t come to school ________ the bad weather.
—No. He didn’t come ________ he was ill.
A. because of, because B. because, because of C. because, because
A
考点突破
much safer: 更加安全的;more smoothly: 更加顺畅地

far: 强调差距非常大,意为“……得多”。
Example: This problem is far more difficult than that one.(这个问题比那个难得多。)
