◆ 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。
3 . We are difficult to do with the new comer . 我们很难与新来的那个人相处。
4 . I have nothing to do with him . 我跟他无任何关系。
deal with 意义很广，常表示“对付”、“应付”、“处理”、“安排”、“论述”、“涉及”等。如：
1 . They could properly deal with all kinds of situations . 他能恰当地应付各种局面。
2 . Deal with a man as he deals with you . 以其人之道，还治其人之身。
3 . This is a book dealing with Asian problems . 这是一本论述亚洲问题的书。
4 . They have learned to deal with various persons . 他们学会了和各种人打交道。
● more 的左邻右舍
含 more 的短语形式五花八门，常令人混淆不清。下面把它分解为左邻(即左边加词语)，右舍(右边加词语)和左右逢源(即左右两边加词语)三种情况。
1. 左邻
◇ all the more 越发，更加。如：
She loves him all the more for his poverty . 她因他的贫困反而越发爱他了。
◇ no more 不再，如：

◇ (not)…any more 再。如：

Ten people or more were killed in the accident . 在这次车祸中死了十个人或者更多。
◇ once more 再一次(= once again) 。 如：
Please say that word once more . 请把那个单词再说一遍。
◇ many more 多得多的，常用于修饰复数名词。如：
The first truck carries many more apples than the second one . 第一辆卡车运的苹果比第二辆运的多得多。
◇ much more 多得多的，修饰不可数名词；多得多(……得多)，修饰多音节形容词或副词的比较级。如：

◇ (and) what is more 而且，加之，常用作插入语。如：

◇ the more…the more… 越 …… 越 …… 。如：
