()、互动释疑 【疯狂背诵】

1.Many people believe that tea was first drunk nearly 5,000 years ago.许多人相信,茶第一次被饮用是在差不多5,000年前。

1). 句子中believe后面是that引导的宾语从句。宾语从句“tea was first drunk nearly 5,000 years ago”运用了一般过去时态的被动语态形式。由“主语+was/were+及物动词的过去分词+by+动作执行者”构成,无需说明动作执行者时可省去“by+动作执行者”。句中主语就是原主动语态的宾语。

   即学即用: (  )1.Mr. Smith’s wallet    outside the gate by Mary. 

A.was founded    B.was found  C.was founded out    D.is found

2)nearly 副词,意为 “几乎,差不多”

Eg:The old man is nearly 90 years old.

Almost, nearlyhardly的区别

Almostnearly都有 “差不多”的含义,在表达时间或用在all,alwaysevery等词的前面是两者可以互换。

②和no, nobody, nothing, never等词连用时,多用almost; not连用时多用nearly

即学即用:     Almost, Nearlyno one believed her。几乎没人相信她。

Shes not           almost, nearly) 20 years old。她还不到20岁。

hardly作副词,意为“几乎不;简直不”。

2. In England, tea didn’t appear until around 1660,but in less than 100 years, it had become the national drink.

1). until 用在否定句中,表示句子的动作直到until短语所表示的时间才开始发生,即表示动作的起点。一般译为“直到……才”或“直到……之前(……还不) 。例如:I won’t leave until you promise to help me.

  即学即用:.直到昨天晚上12,他才上床睡觉。

He      go to bed              12 o’clock last night. 

.直到你完成你的作业,你才能和朋友们出去。

You     go out with your friends         you finish your homework. 

2.Less than 少于,不超过。其反意词组是more than 多于,超过。

3.Some leaves from a tea plant fell into the water and remained there for some time. 茶树的一些叶子掉进了水里,并在那儿停留了一会儿。

1).fall into掉进; 落入  含有fall的短语:fall over跌倒 fall asleep睡着   fall in love爱上;喜爱    fall behind落后

2.remain保持不变;剩余。作动词,强调保持某种状态,后接形容词、名词、介词短语或分词。

Eg:This room remains cool all summer.这个房间整个夏天都很凉爽。(形容词)

   A few pears remain on the trees.树上还留有几个梨。(介词短语)

4.It was quite delicious, and so, one of the worlds favorite was invented.它真的很香,就这样,世界上最受喜爱的饮料之一被发现。

one of+名词/代词复数“……之一

One of后面接名词或代词的复数形式。当“one of+名词/代词复数“在句中作主语时,其中心词为one,故其后的谓语动词要用第三人称单数形式。

即学即用:   One of my pen friends in Beijing       be going to my city next month. 下个月我的一位北京的笔友要来我所在的城市。

One of…的其他用法

在“one of+名词复数“结构中,如果名词前有形容词修饰时,则形容词需要最高级形式,构成”one of+形容词最高级+名词复数“结构。

Eg: Yu Dan is one of the most popular professors in China.

5.It is believed that tea was brought to Korea and Japan during the 6th and 7th centuries. 人们认为茶在6世纪和7世纪之间被带到韩国和日本。

“世纪“的表达法:Century 作名词,意为“世纪;百年“,复数形式为centuries。当表示第几世纪时,century前用序数词,且序数词前要加the

即学即用: This book was written           centuryago.

Was the telephone invented in                nineteencentury?

6The tea trade from China to Western countries took place in the 19th century.茶贸易从中国传到西方国家发生在19世纪。
