1.中国的空气污染日益严重

2. 造成这一现状的主要原因

3.我的建议

In recent years, a word catches the line of sight of people--"PM2.5"--air pollution. We realize that the sky is no longer blue; the air is no longer fresh; we need to wear a mask when going out; more and more people are suffering from respiratory diseases. This problem is not built in short times. Air pollution has become an increasing concern in China.

A few days ago, a reporter named ChaiJing made a documentary called "Under the Dome" to reveal the reason for air pollution in China. She made a research and found that 60% of PM2.5 is derived from coal and fuel oil, especially most of the coal is burnt without cleaning and processing. And the vast majority of diesel vehicles are not qualified. The government organs are not able to pursue legal responsibilities of the companies which produce the fake diesel vehicles, because the legal system is not perfect. In reality, the monopoly of oil industry; the principal of relevant enterprises is lacking a sense of social responsibility; excessive pursuit of personal benefit; and relevant system is not perfect; the law is not clear; all these is the root cause of this situation.

We are living in a same world, breathing the same air, sharing the same consequences. Therefore, both of the government and citizens, we all have the responsibility and obligation to make contributions to improve the air quality. For government, they should strictly enforce environmental laws and regulations; crack down on those guilty of creating illegal emissions and ensure they pay a heavy price for such offences. Otherwise, they should open the vote link when formulating relevant standards; reducing coal use or use the coal with cleaning and processing; developing the use of natural gas and other clean energy. Although all kinds of the stubborn trouble have existed for a long time, if they determined to fight pollution with all them might, I believe that the situation will get better. For us, we ought to make a phone call "12369" to report if we saw irregularities, such as oil gas leak in gas station, dust in work site. In addition to this, we ought to refuse to buy products of polluting companies.

Notwithstanding what we do is very little, we acquire steady in our heart. If we don't make measures right now, when? What time are we waiting for? Really want to wait until we lived in a world like the UK in 1860s that people cannot live anymore? I really hope that we can keep the APEC blue sky through our effort, give the original elegant beauty back to the old country, and protect the homeland for our descendants.

在最近这几年中,有一个词抓住了人们的视线——PM2.5——空气污染。我们发现天不再是蓝的,空气不再是清新的,我们出门要戴口罩,

不定代词用法总结

疑问代词用法总结及练习

疑问代词用法总结及练习 句子是英语学习的核心。从句子使用的目的来分,它可分为四类 1、陈述句(肯定句和否定句) 2、疑问句(一般疑问句、特殊疑问句和选择疑问句) 3、祈使句(肯定句和否定句) 4、感叹句。 四大句子类型的相互转换,对于学生来讲是个难点,为此,可通过说顺口溜的形式来帮助学生解决这一难题。 如:将陈述句变成一般疑问句,可以变成这样的顺口留:疑问疑问调个头,把be(系动词“is are am”)放在最前头。 如:将陈述句的肯定句变成否定句,我们就可以这样说:否定,否定加“not”,加在何处,加在系动词的后面。 在句子相互转换的题型中,最难的要算“就下列划线部分提问”或是“看答句,写问句”这种题型了,其实,我们只要熟练掌握疑问词(what,what time, what colour, where, when, who, whose, which, how, how old ,how tall, how long, how big, how heavy , how much, how many等等)具体用法。

法语主要介词及用法

法语主要介词及用法 Avec 似曾相识Il faut discerner le bien d'avec le mal. 讲解avec 的段落,却偏偏要先引出一个d'avec,这是为什么呢?介词de 和介词avec 的组合主要是和一些表示“甄别”、“区分”之意的动词用在一起的。 除了例句中的discerner 之外,还有destinguer ,séparer。例如: distinguer l’ami d’avec le flatteur (分清朋友和献媚者); séparer l’or d’avec l’argent (区分金子和银子)。 从这些例句中可以看出,我们所熟悉的avec 的本意在d’avec 中已经丧失殆尽了。而首先介绍d’avec 的意图则在于提醒读者,介词和介词组合在法语中有很多,值得注意。 亲密接触à介词avec 在复合句中的运用 介词avec 的最基本词义是“和”。不过,在具体的语境中,这个“和”字又可化为“具有”、“对于”、“同意”、“随着”、“使用”、“反对”等意思来讲。 例如: Je sors toujours avec ma femme. 我总是和太太一起外出。(和) J'ai loué une chambre avec salle de bains. 我租了一间带浴室的房间。(具有) Ce professeur est très gentil avec ses étudiants. 这个老师对学生总是很和蔼可亲。(对于) Tout le monde est d’accord avec moi. 所有人都同意我的意见。(同意) Mon grand-père se lève avec la jour. 我的祖父天一亮就起床。(随着) Il a ouvert la bo?te de conserve avec un couteau. 他用一把小刀开了罐头盖。(使用) C'est un combat avec un ennemi supérieur en nombre. 这是一场同数量上占优势的敌人间的战斗。(反对)

doubt 与 suspect 的用法比较

doubt 与 suspect 的用法比较 doubt 与suspect 作动词用,都有“怀疑”的意思,但实际上它们的用法还是有区别的。下面我们就来比较一下: 一. 如果后面接名词、代词或名词性词组时,两者基本上可通用。例如: I doubt/suspect the truth of her statement. 我对她那番话的真实性表示怀疑。 He says he can cure me,but I still doubt/suspect him. 他说他能治好我的病,但我仍对他不放心。 二. 如果后面接that 从句,意思就截然不同。doubt 意为“无把握;不相信(question the truth of;don't believe/think )”,怀疑其无。suspect 意为“有存在或属实的想法;相信(have an idea of the existence;believe;guess )”,怀疑其有。例如: I doubt that he has stolen my watch. 我不相信他偷了我的手表。 I suspect that he has stolen my watch. 我怀疑/ 猜想他偷了我的手表。 The doctor suspected that he was ill with flu. 医生怀疑/ 认为他得了流感。 这时doubt 更多用于否定句或疑问句中。如: I don't doubt that he is right. 我确信他是对的。 I didn't doubt that he would come. 我当时相信他会来的。 Why did she doubt that they were cheats?她为什么怀疑他们是骗子? 三. doubt 用于肯定句中时,多接whether/if 引导的从句,意义与that 从句不同,这时意为“不敢肯定(feel uncertain about )”。而suspect 不可接这种从句。例如: I doubt whether/if he'll come. 我不敢肯定他来不来。 It's raining hard. I doubt whether it will be fine tomorrow. 雨下得很大,我不敢说明天会晴。四. 其他搭配。 doubt 可作不及物动词,用于doubt of sth;suspect 用于suspect sth to be,suspect sb of (doing)sth . be suspicious of sth. = be doubtful of 例如: She never doubted of his success. 她从不怀疑他的成功。 I suspected him to be the spy. 我认为他就是那个间谋。 What made you suspect her of having taken the money?你凭什么怀疑钱是她偷的? involve用法 及物动词vt. [W] 1.使卷入,连累;牵涉[(+in/with)] That's no concern of mine. I'm not involved. 那与我无关,我未卷入。 Don't involve me in your quarrel! 不要把我牵扯进你们的争吵中! 2.需要,包含,意味着[(+in)][+v-ing] His work involves occasional journeys. 他的工作偶尔需要出差旅行。 3.使专注,使忙于[(+in)] He was involved in writing his doctoral dissertation. 他在聚精会神地写他的博士论文。 另外: This is indeed an involved sentence.这真是个复杂难懂的句子。 由动词involve演化而来的形容词involved,放在名词前和名词后有不同的含义。放在名词后使用,大多是这个词的本意“牵扯进来的、有关的、卷入的”;放在名词前使用,意思大多是“复杂的、不易懂的、难于解开的”例句: The plot of the play has been criticized as being too involved.剧情节被批评为过分纠缠不清。
