Traffic Problems
It’ reported that in many cities, like Beijing, Shanghai and Guangzhou, nearly 70% of the families are considering buying a family car within the 5 to 10 years. I think private cares should not be encouraged in China, especially in the big cities.
As you know, China’s traffic situation is as bad as other major countries in the world. There is too much traffic in city and it’s getting worse. Too many people drive to work. Commuters have to spend a lot of time on the way. Some times the traffic jams cause long halts. Besides that, another big problem in many cities is the terrible air pollution. Too many private cars are causing too much smog. It’s especially bad in rush hours. Central city or business district in the downtown is especially affected by the air pollution.
According to this situation, I think government should plan to extend the extra charge for private cars with high emissions and invest more on uplift of public transportation. This will result in more people taking public transportations as buses and underground. Fewer people will drive to work.
Everybody hope to live in a cleaner and safer city. I think if forget buying a family car, you can get more.
2. 英语写作中存在的语言错误如：主谓一致、时态处理、冠词用法、名词单复数形式、单词词性怎么区分和搭配
一、概述
在作谓语的动词用来表示动作（或情况、状态）发生时间的各种形式称为时 态。由于英语属于曲折变化的语言，其动词时态的变化要通过词的曲折词形变化来体现的，因而也就有了现在式、过去式、过去分词式三个基本词形。英语中根据说话的时间不同有时和体的不同，主要有十六这十二种时态可以列表如下：
一般现在时 现在进行时 现在完成时 现在完成进行时
一般过去时 过去进行时 过去完成时 过去完成进行时
一般将来时 将来进行时 将来完成时 将来完成进行时
一般过去将来时 过去将来进行时 过去将来完成时 过去将来完成进行时
这些时态的形式可以用下表来表示，以do 动词为例：
一般时态进行时态完成时态完成进行时态
现在do
doesbe （am, is are ） doinghas doing
havehas been doing
have
过去did be （was, were） doinghad donehad been doing
将来shall do
will shall （will） be doing shall （will） have doneshall （will） have been doing
过去将来should （would） doshould （would） be doingshould （would）
have done should （would） have been doing
下面根据这些时态常用的程度不同分别说明它们的用法。
二、各时态详解
1、一般现在时
一般现在时主要由动词原形表示，但第三人称单数后要加词尾-s，另外be 和have要根据人称的变化使用特殊的形式。一般现在时主要表示经常性的动作或存在的状态，还可用来表示普遍真理。
The Yangtze rises in Qinghai. 长江发源于青海。
Actions speak louder than words. 行动胜于言辞。
We have friends all over the world. 我们的朋友遍天下。
2、现在进行时
现在进行时是由助动词be加现在分词构成的。主要表示现在或现时刻这一阶段正在进行的动作，有时候还用来表示一个最近按计划或安排要进行的动作。
How are things getting on with you？ 工作进行的怎么样？
Someone is asking for you on the phone. 有人找你接电话。
They are publishing a new version of the playscript by Taso Yu this autumn.
今年秋天他们要出版曹禺剧作的一个新译本。
3、一般将来时
一般将来时由助动词shall （will）加动词原形构成。它表示将要发生的动作或情况。
They will sit the post-graate examinations next autumn.明年秋他们要参加工硕考试。
The teacher will not let me go home before I have finished my homework.
老师要我做完作业才能回家。
4、一般过去时
一般过去时由动词过去式表示，动词be 根据人称有was和were两个词形，规则动词在词尾加-d-或ed；其他动词参阅不规则动词变化表, 该时态主要表示过去某时发生的动作或情况。

The area has suffered from disastrous floods throughout its history.
这个地区历史上一直遭受水患之苦。
注意：过去时和现在完成时的区别：
现完成时的基本特点是它和现在有密切的联系，或是指迄今为止这一段时间的情况，或是过去发生的事对现在造成的影响或结果等。而过去时主要强调过去某时刻所发生的动作或情况，与现在没有任何联系。如：
Up till now we have planted over 10,000 apple trees.
到目前为止我们共种了一万多棵苹果树。
I saw him a minute ago. 我前一会还见到他的。
6、过去进行时
过去进行时是由助动词be的过去式加上现在分词构成的，主要表示过去某个时刻正在进行的动作。

他们带我们去参观了他们正在修建的化纤厂。
7、过去完成时
过去完成时由助动词had加动词的过去分词构成，主要表示过去某时刻前业已完成的动作或存在的状态，其实就是指过去的过去。使用时往往要要在从句中或有一个明确的过去时间状语。

8、一般过去将来时
一般过去将来时由助动词would加动词原形构成，主要表示从过去某一时间角度看以后将要发生的动作。含这个时态的句子常带一个表示“过去某个时间点”的状语。这个状语或是一个短语，或是一个句子。这个时态常用于：宾语从句或间接引语中。例如：
When I thought about it, I wondered what their reaction would be.
当我考虑这件事时，我想知道他们的反应是什么。

一般将来完成时由shall （will） + have + 过去分词构成。主要表示在将来某时业已发生的动作。如：

这课课文结束后，我们就学了二十课课文了。
By the next month, I'll have finished my task. 到下个月，我将完成任务。
They will have hit the year's target by the end of October.
到十月底他们就可完成全年的指标了。
10、现在完成进行时
现在完成进行时由have（has）been加动词的现在分词构成，表示发生在过去的某个动作延续到现在或刚刚完成，或许还要继续延续。这种时态侧重于这个动作的连续性，或者说不间断性。例如：
I've been waiting for you for the whole morning. 整个上午我一直在等你。
It has been raining for three days. 雨连续下了三天。
Where have you been？ 你去哪儿啦？

3. 我写英语作文总是分不清语法问题，每次写作文 总感觉语法没什么问题，结果老师一批，全是错的，我们老师
主谓一致是指主语与谓语在数上要一致。把握主谓一致问题，考生主要解决的是对不同结构的主语单复数的认定，进而选择适当的谓语。解决主谓一致主要遵循三个原则：
语法一致原则
意义一致原则
就近一致原则
很多情况下应该综合利用这三个原则来处理主谓一致，在不同情况下可能应用三个原则中的不同原则，具体应用哪种原则应该视具体情况而定。总结如下：
一.谓语动词用单数的情况
1.动名词短语、不定式短语、名词性从句做主语，谓语用单数。如：
Buying clothes is often a time-consuming job because those clothes that a person likes are rarely the cones that fit him or her.
(1987年考研题)
To understand the situation completely requires more thought than has been given thus far.
2.表示时间、距离、金额、重量、面积、体积、容积等度量的名词短语做主语时，谓语用单数。
Two weeks was too long
Five times five makes twenty five
3.一般用and连接的两个单词或短语做主语时候，谓语用复数，但是下面用and连接的主语表示一个概念，谓语用单数：
law and order 法制 soap and water 肥皂水
a cup and saucer 茶杯碟子 fork and knife 刀叉
the needle and thread 针线 trial and error 反复尝试，不断摸索
horse and carriage 马车 time and tide 岁月
bread and butter 奶油面包 the ebb and flow 盛衰，潮涨潮落
如： If law and order not preserved, neither the citizen nor his property is safe.
A. is B. are C. was d. were
答案：A。
4.表示学科和某些疾病名称的名词是复数形式，作主语时候谓语动词用单数形式
Linguistics is a branch of study on human language.
5.有些名词形式上是复数，意义上是单数，根据意义一致原则动词用单数
The chaos was stopped by the police
The news is a great encouragement to us
A series of debates between the lectures was scheled for the next weekend.
6.用and 连接的成份表示一个单一概念时候，动词谓语用单数形式
Bread and butter is our daily food
Time and tide waits for no man
二. 谓语用复数情况
1. 由and, both …and, 连接的并列主语，和both ,a few, many ,several 等修饰语后面谓语动词通常用复数形式。
Few people know he and I were classmates when
