【学法指要】
单元易错用的熟词释疑
● POPULATION 能用复数吗？
在 Lesson 34 课文第一段中有这样一句：Many parts of the world , which once had large populations and produced plenty of crops , have become deserts . 这里的 population 为什么使用复数？
【释疑】
◆ population 多用单数，指某国家或地区的人口。如果用复数，指世界不同地区的人口。例如：
Many parts of the world , which once had large populations and produced plenty of crops , have become deserts . 世界上许多地区曾经人口众多，五谷丰登，而今却成了沙漠。
According to the latest census , China\'s population has increased . 根据最近的调查，中国的人口增加了。
◆ population 直接作主语时，谓语动词一般用单数形式指住在某地区的全体居民，为不可数名词，但前面有 some , most 特别是分数或者百分数时，谓语动词常用复数。例如：
The population in these villages has to get its water from wells . 住在这个村子里的人必须自井中汲水。
The population of the city rose by 20% . 这个城市的人口增长了 20 % 。
Most of the population in this city are workers . 这个城市大多数人是工人。
At present about 38% of the Chinese population smoke . 目前中国大约有 38% 的人吸烟，
In India , however , the population of tigers has increased , from 2,000 in 1972 to about 5,000 in 1989 .
然而，在印度，老虎的数量增加了 ， 1972 年只有2，000 只，1989年增加到了大约5，000 只。
In the south most of the population live on rice . 在南方，绝大多数人以大米为食。
◆ 问“人口多少”用 ：what 或者 how large 。不用 how many 和 how much 等词。说人口多用 large或者 great , 说人口少用small 。例如：
?What\'s the population of China ? 中国的人口是多少 ？
?China has a large population . 中国人口众多。
The population of Japan is smaller than that of US . 日本的人口比美国的少。（注意对比中的 that 不要省略）
The population of Beijing is larger / greater than that of Xi\'an . 北京的人口比西安的多。
Do you know what the population of Africa is ? = Do you know how large / great the population of Africa is ? 你知道非洲的人口是多少吗 ？
That country has a small population . 那个国家人口稀少。
What\'s the population of the world ? 全世界有多少人口 ？
This village has a population of about 1,500 .
◆ 在表达某地有多少人口时可以用：
地点 + has a population of + 数词 （+ people ）
The population of + 某地 + be + 数词 。
地点 + with a population of + 数词
那个国家有 5，000 万人口。
China has a population of 1,2 billion . 中国有 12 亿人口。
That country has a population of fifty million ( people ) .
The population of that country is fifty million .
The country is one with a population of fifty million people .
◆ 当 population 表示抽象意义时，不加冠词。例如：
Since 1949 , the people\'s living standard has been raised , causing a big rise in population . 自从 1949 年以来，在中国，人民的生活水平得到了提高，导致人口有了很大增加。
● appear ，seem ，look “看来像”吗 ？
appear , seem , look 看来很相似，均有“好象，看起来象”之意，在使用时应从以下几方面：
一、含义上的差异
appear 是指根据事物的外表表象做出判断的，但实质上并不一定如此；seem是表示说话人主观上的判断，暗含有一定的根据，往往接近事实的判断；look是根据视觉印象而得出的判断，实质上也可能如此。例如：
He has a small salary but he appears rich . 他工资很低却显得很富。(其实并非如此)
He seems rich . (I think he is rich .) 他看起来很富有。(根据个人的主观判断而推断出)
He looks rich . 他很是富有。(从他花钱办事的言行中可出感觉出)
二、用法上的差异
1. appear，look，seem 后均可带名词、形容语、to be 结构。
He appeared / seemed / looked an honest man . 看来他是一个诚实的人。
He appeared (to be) sad when he heard the bad news . 当他听到这个坏消息时，似乎很悲伤。
注：在接 to be 结构时，to be常常被省略。例如：
The flowers seem (to be) more beautiful at this time . 此时，花儿好象更漂亮。

2. look 可用于进行时，而 seem , appear 一般不能。如：
You\'re looking quite a different person . 你现在的样子完全是另一个人了。
3. appear 和 seem 之后可接动词不定式的各种形式，而 look 之后除了能接to be 结构外，不接其它动词不定式形式。
He appeared to be proud of himself . 他好象为自己而骄傲。
She doesn\'t seem to have been to Beijing . 她好象没有去过北京。
He looks to be the best person for the job . 他看来是做这项工作最合适的人。
4. look , seem 能与介词 like 构成习语，意思是“看上去象”，而 appear 却不能。例如：
It seems like years since I last saw you . 自从上次见到你后，好象很久没有见到你了。
The new building looks like a hospital . 这座新建筑物看起来象一座医院。
5. seem , look 后均可接 as if , as though 引导的表语从句，若表示不能实现的事实，则用虚拟语气，而 appear 则不能。例如：
It seemed / looked as if it was going to rain . 看起来天快要下雨了。
It seems as if he were to start at once . 看来好象他马上就要动身。
6. appear 和seem 均可接 that 引导的从句，而 look 不能。
It seems / appears that the book is too difficult for us . 这本书好象对我们来说太难了。
It seems that John will win the race . 好象约翰能跑第一。
7. appear 和 seem 可用于there be 结构中，而 look 不能。如：There appeared / seemed nothing to be done . 大家似乎觉得没有办法了。
There appears to have been an accident . 好象出了一次事故。
● do with 与 deal with 用法辨析
do with 与 deal with 都可作“处置”讲的。do with 常与连接代词 what 连用，而 deal with 常与连接副词 how 连用，如：
1 . I don\'t know how they deal with the problem . (= I don\'t know what they do with the problem . )我不知道他们如何处理这个问题。
2 . He is easy to deal with . (= He is easy to do with . 这时“do”是不及物动词)他是容易相处的人。这两个词组在使用时有细微的差别。一般地说，do with 表示“处置”、“忍受”、“相处”、“有关”等。如：
1 . They found a way to do with the elephant . 他们找到对付那头大象的办法了。
2 . We can\'t do with such carelessness . 我们不能容忍这种粗枝大叶的作风。
