词汇精讲
1. Internet n. （国际）互联网；因特网
Internet为专有名词，也可以理解为世界上独一无二的东西，所以Internet要大写，且前边加the。“上网”可以翻译为use/surf the Internet。常用短语还有on the Internet意为“在互联网上”。
e.g. You can use the Internet to find all kinds of information.
e.g. There are all kinds of information on the Internet.
随学随练
练习1. It is important that children can _______________ safely.
练习2. I’m sure you’ll find some information about it _______________.
2. once adv.一次； twice adv.两次
（1）once和twice用作副词，意为“一次”和“两次”, 经常用来回答“How often”或“How many times”引导的特殊疑问句。英语中“三次或三次以上”用“基数词+ times”表示，如three times三次。
e.g. He visits his parents once/twice/three times a month.
（2）once还可意为“曾经”，常与过去时连用。
e.g. I once lived in Hebei Province.
（3） twice还可意为“两倍”。
e.g. Our classroom is twice as big as yours.

A. How many times; Two times B. How often; Two times
C. How often; Twice D. How many times; Twice
3. although conj. 虽然;尽管;即使
although为连词，可以引导让步状语从句，相当于though。although和but都为连词，故不能用在同一个句子之中。
e.g. Although it rained heavily yesterday, all the students arrived on time.
= It rained heavily yesterday, but all the students arrived on time.
随学随练
______________ he was tired,______________he went on working.

练习3. Jim goes to school ______________bike.
练习4. My mother cuts the apple ______________ a knife.
5. full adj.忙的；满的；饱的
（1） full作为“满的”，经常用到固定搭配be full of=be filled with“充满……”，反义词为empty(空的)。
e.g. This cup is full of water, but that one is empty.
（2）full还可以表示“忙的”。
e.g. The next week is quite full for me.
（3）full还可以表示“饱的”，反义词为hungry(饥饿的)。

（1）hardly本身具有否定意义，不能与其他否定词连用。
e.g. There is hardly any food left.
e.g. I can hardly tell the differences between the twins.
（2） hardly ever意为“几乎从不”，ever起强调作用。
e.g. We hardly ever go out.
（3）hard作为形容词意为“硬的；困难的”。hard也有副词词性，意为“努力地”。
e.g. The rock is really hard.
e.g. This is a pretty hard question.
e.g. Little Tom works hard.

People in the US watch TV for about 25 hours a week. Eighty-five percent of people watch TV every day, and only two percent watch at least once or twice a week.
