4. They need hundreds of hours of study and practice， and even this will not guarantee success for every adult language learner.

注意句中hundreds of hours的用法，阅读课本第六页注解2.

请翻译下面的词组：

1） 十个学生 ten students

数十个学生 tens of students

2） 五百年 five hundred years

数百年 hundreds of years

3） 两千年 two thousand years

数千年 thousands of years

4） 三百万美元 three million dollars

数百万美元 millions of dollars

5. Language learning is different from other kinds of learning.

句中be different from 意为“与…不同”，如：My opinion is different from yours.（我的观点与你的观点不同。）

请注意下面三个句子中所用的词组：

Man is different from all the other animals in his ability to learn and use a language.

Man differs from all the other animals in his ability to learn and use a language.

The greatest difference between man and all the other animals is his ability to learn and use a language.

从上面的句子中可以看出differ是动词，different 是形容词，difference是名词。

6. … find it difficult to succeed in language learning.

… find it difficult to succeed in other fields.

句中的it是形式宾语（formal object），真正的宾语（real object）是不定式to succeed in language learning，此类用法在英语中很常见，请注意掌握。如：At first I found it difficult to remember all these new words.（开始我感到记住这些单词很难。）

请翻译下面的句子：

1） 外面的噪音使我无法继续工作。

（The noise outside made it difficult for me to go on with my work.）

2） 他们觉得再争论下去是浪费时间。

（They consider it a waste of time to argue any further.）

3） 她认为把真相告诉小王是对的。

（She thought it right to tell Xiao Wang the truth.）

7. Language teachers often offer advice to language learners.

本句中注意掌握动词offer的用法，请看下面的例句：

1） He offered me a cup of tea after I sat down. （我坐下后他给我端来一杯茶。）

2） What suggestions would you like to offer to those young teachers？ （对这些新教师你有什么建议要提吗？）

3） This shop offers all kinds of stationery.（这家商店供应各种文具。）

4） The old man offered me 100 yuan for the used bike.

（那个老人向我出价100元买这辆旧自行车。）

5） She offered to help me with my English.（她表示愿意帮我学英语。）

句中的advice为不可数名词，其后不加s，正如课本第六页注解3所说，有许多东西在汉语中是可数的，在英语中却是不可数的。如news， information， paper 等，若要表示“一个”这类概念，就必须加a piece of这类定语，例如：

a piece of news

a piece of advice

a sum of money

a piece of bread

8. Read as much as you can.

句中的much 是副词，用副词作同等比较时，可以用as … as和so … as 这种结构，如：

1） Read as much as you can and your vocabulary will be enlarged.（尽量多阅读，你的词汇量就会扩大。）

2） We must arrange everything as well as we can.（我们要把一切尽可能地安排好。）

3） Please give me a call as soon as possible.（请尽早给我打电话。）

4） I don't speak English so well as you.（我英语讲得没你好。）

9. Practice speaking the language every day.

practice 在美国英语中可以做动词也可以做名词，而在英国英语中，practice是名词，动词的拼写则是practise.

作动词用时，其后只能跟动名词，不能跟不定式。如：It is really no fun to practice running in such hot weather.（在这样炎热的天气里练跑步可真不是好玩的。）

10. Language learning research shows that successful language learners are similar in many ways.

that successful language learners are similar in many ways 是宾语从句。在非正式场合下that引导宾语从句时可省略。如：I think （that） you are right.

请翻译下面的句子：

1） 小男孩承认是他打碎了窗玻璃。

（The little boy admitted that he broke the window.）

2） 大量证据表明他是有罪的。（Plenty of evidence shows that he is guilty.）

3） 我保证将会给他更多的帮助。（I promised that I would give him more help.）

11. … they discover their own way to learn the language. to learn the language

不定式做定语，例如：Is it the best way to solve the problem？（这是解决问题的最好方法吗？）

请翻译下面的句子：

1） 他没有勇气承认自己是无知的。（He has no courage to say that he is ignorant.）

2） 这将是一个交流思想的好机会。（This will be a good opportunity to exchange ideas.）

3） 他们在会上没有发言权。（They had no right to speak at the meeting.）

12. Instead of waiting for the teacher to explain， they try to find the patterns and rules for themselves.

动词不定式to explain和名词 teacher构成复合结构，作wait for的宾语，称为复合宾语。此类用法在英语中很常见，例如：

1） I'll get someone to repair the bike for you.（我去找人来帮你修自行车。）

2） He wants you to call him in the afternoon.（他要你下午给他打电话。）

3） The teacher is waiting for the students to answer the questions.

（老师在等学生们回答问题。）

4） You can count on him to give you full support.（你放心，他会给你全力支持。）

请注意 instead of 与 instead 的区别：

1） Instead of staying at home watching TV， he went out for a walk.

He didn't stay at home watching TV， instead he went out for a walk.

2） Instead of having milk for breakfast， he had a cup of coffee.

He didn't have milk for breakfast， instead he had a cup of coffee.

13. When they guess wrong， they guess again.

wrong常常作形容词或动词用，而本句中的wrong则作副词用。请注意下面句子中wrong的词类：

1） He was annoyed that he had been given some wrong information.（wrong adj.错误的）

2） I knew I had wronged her terribly when I gave her all the complaints.（wrong v. 冤枉）

3） The whole class burst into laughter when the teacher pronounced her name wrong.（wrong adv.错，不对）
