therefore用法:

用作副词 (adv.)

  • therefore的意思是“因此,为此,所以”,是副词,引导结果、结局或结论,不能误作连词用。

  • therefore可引出一个独立句,但不能连接两个句子,因此当therefore前没有and等连词时,前面须用分号。

  • 连接副词therefore用于句首时后面无需逗号,若位于句中前面可加也可不加逗号。

  • therefore也可用于推理,作“故…,由此得出”解。

  • He was the only candidate; therefore, he was elected.

    他是唯一的候选人,因此,他当选了。

  • We do not have enough money. Therefore we can not afford to buy the new car.

    我们的钱不够,因此买不成这辆新车。

  • I was ill, and therefore I could not 空白e.

    我病了,所以没能来。

  • He was very tired, and therefore he didn't give the market report.

    他非常疲倦,所以没能作市场报告。

therefore是副词,但有时具有连词作用。

1、当therefore在整句中时,它一般不放句末,放在句首后要有逗号,放在句中时前后都要有逗号。

例如:Therefore,we must learn English well.

They therefore can learn English well.

Many fast food restaurant ,therefore,have red furniture or walls.

2、当therefore用在分句中时,即一个句子一部分表示原因一部分表示结果。

这时一般词前要用分号,其后用不用逗号无所谓。若第二个分句前是逗号或无符号,则要注意therefore是副词,和so不一样,要保持句子完整,应用and therefore。

例如:I had a headache,therefore I could not go to your party.

The truth is that junk bonds were misnamed, and therefore misunderstood.

They had seen him trawling and therefore knew that there were fish.

3、在我们英语考试中,大家最好用therefore 别用so。因为so比较简单,显得文章水平低,而用therefore会显得你的作文更好,更容易引起阅卷人的注意,给阅卷人好的印象。

The lime water has turned cloudy, therefore carbon dioxide has been produced during the experiment.

Rescue workers are therefore drilling a hole on the north side of the mine. 

thereby1....;/and thereby doing 2 Thereby ... thus 1...;/and thus doing 2Thus ... however 1 ...;however ... 2However,.... therefore 1....;therefore .... 2 Therefore.... 我是最佳答案吧~sat规定副词和形容词不能连接两个句子,一定要用;或连词如and ,but,as well as ,or 等等的

这样的句子叫做并列句,即由两个或两个以上的简单句组成的句子,常由连词连接。

在结构上各分句是平等的,而不是一个从属于另一个。

常用的连接方法有四种:(1)分号 The moon was hidden by the clouds; not a star could be seen.(2)用连词and, for, but, yet, or, nor, so连接。

例如:I chose to major in English, and I'm now working hard at it.(3)用连接副词连接,诸如also, besides, however, otherwise等,第一分句后要用分号,连接副词之后用逗号,比如:Applicants need a college degree and two years' experience; moreover, they must have 空白puter skills.(4)用词组连接,如in fact, for example, on the contrary等。

例如:John worked hard all years; as a result, he made excellent grades. eg:You are right, therefore we should support you.therefore按说是adv啊……这个句子中therefore就是因此的意思,你是对的,因此我们将支持你。

严谨的写法,我想应该是You are right. Therefore, we should support you.两个句子直接用逗号连接是可以的,表示平行的叙述。

我翻了一下书,比如有这个句子:That is to say, the context of each word is collected, along with the word itself. 又如:The man was very sick, now. He crawled about, on hands and knees.有看不懂的再问我吧。

therefore用法:用作副词 (adv.)therefore的意思是“因此,为此,所以”,是副词,引导结果、结局或结论,不能误作连词用。

therefore可引出一个独立句,但不能连接两个句子,因此当therefore前没有and等连词时,前面须用分号。

连接副词therefore用于句首时后面无需逗号,若位于句中前面可加也可不加逗号。

therefore也可用于推理,作“故…,由此得出”解。

He was the only candidate; therefore, he was elected.他是唯一的候选人,因此,他当选了。

We do not have enough money. Therefore we can not afford to buy the new car.我们的钱不够,因此买不成这辆新车。

I was ill, and therefore I could not 空白e.我病了,所以没能来。

He was very tired, and therefore he didn't give the market report.他非常疲倦,所以没能作市场报告。

拓展资料:therefore是副词,但有时具有连词作用。

例如:Therefore,we must learn English well.They therefore can learn English well.Many fast food restaurant ,therefore,have red furniture or walls.2、当therefore用在分句中时,即一个句子一部分表示原因一部分表示结果。

例如:I had a headache,therefore I could not go to your party.The truth is that junk bonds were misnamed, and therefore misunderstood.They had seen him trawling and therefore knew that there were fish.3、在我们英语考试中,大家最好用therefore 别用so。

因为so比较简单,显得文章水平低,而用therefore会显得你的作文更好,更容易引起阅卷人的注意,给阅卷人好的印象。

The lime water has turned cloudy, therefore carbon dioxide has been produced during the experiment.Rescue workers are therefore drilling a hole on the north side of the mine.

你好:连接副词可分为两类,一类是用于连接句子或从句,常见的有therefore, besides, otherwise, however, moreover, still, thus, meanwhile等;另一类是用于引导从句或不定式,主要的有when, why, where, how 等。

很明显你问的属于第一类。

那幺,举例:1.连接副词等连接词的作用,连接两个句子或子句,如:however, so, then, therefore,but,although2.连接副词通常位于子句的句首,有的也可位于句中。

They talked about it for hours. Finally, they decided to go。

他们对此商量了好几个小时,最后他们决定去。

finally作为连接副词,放在句子的句首。

I have never been to Wales. I, therefore, don't know much about it.我从未去过威尔士,因此我对它知道的不多。

therefore作为连接副词,位于句子的句中。

首先告诉你的是,例子1中副词位于子句句首,而子句也是一个完整的句子,不能和从句混为一谈。

所以,连接副词在大多一般情况下可以放在句首引导句子。

其次,如果有一个分号,其实,分号的作用就相当于句号的作用。

它隔开的也是两个句子。

故可引导句子。

and连接两个句子,如果句子主谓相同,可以一起省略主语和谓语。

并列句(空白pound sentence)由两个或两个以上的简单句并列而成。

常见的并列句结构是:简单句+等立连词+简单句。

这种简单句常被叫做分句。

等立连词之前可用逗号,也可不用逗号。

如:They were happy and they deserved their happiness. 他们是幸福的,他们也该得到幸福。

(等立连词是and)The signal was given, and the steamer moved slowly from the dock. 信号发出了,轮船缓缓驶出码头。

(等立连词是and,前有逗号)(3)Hurry or you won't make the train. 赶快,不然你赶不上火车。

(等立连词是or)Honey is sweet, but the bee stings. 蜜是甜的,但蜜蜂却会蜇人。

(等立连词是but)有时亦可不用,只用分号、冒号等把分句隔开。

如:Heavy clouds rose slowly from the horizon; thunder drummed in the distance. 浓云从地平线缓缓升起,远处雷声隆隆。

(用分号连接)He knocked at the door again and again: there was no answer. 他一再敲门,但无人应门。

(用冒号连接,表结果)两个或两个以上的简单句的关系如不很紧密,等立连词可引导单独一个句子。

如:You're alive! And she's dead. 你活着!而她却死了。

(等立连词and引导单独句子)I'm sorry to trouble you. But can you direct me to the nearest post office? 对不起打扰一下。

你可以告诉我最近的邮局在哪儿吗?(等立连词but引导单独句子)并列句的分句亦可用连接副词连接。

如:I had a drink, then I went home. 我喝了杯酒,然后回到了家。

(连接副词是then)It rained, therefore the game was called off. 由于有雨,因而那场球赛取消了。

(连接副词是therefore)He was angry, nevertheless he listened to me. 他生气了,但听我的话。

(连接副词是nevertheless)I want to go to the party—however, I have no transport. 我想去参加聚会,但我没有交通工具。

(连接副词是however)I have only an old car; still it is better than nothing. 我只有一辆旧车,但也比没有好。

(连接副词是still)I am busy today, so can you 空白e tomorrow? 我今日很忙,那你能明天来吗?(连接副词是so)

此句应该用so, 表示“因此,所以”时so是连词,可以连接两个简单句;而therefore是副词,准确的说是连接性副词,不能直接用来连接两个简单句,它可以放在句首,后面加逗号,也可以放在句中作为插入语。

另外,and therefore 相当于so. 还有therefore常表示很强的推断,用法比较正式,而so则常用于口语中。

试比较下面的句子He is kind; therefore,/ thus we all like him.He is kind , so we like him.He is kind . Therefore/ Thus we like him.

Therefore和Thus的区别:一、词义不同:therefore=因此,所以;用于对某事物进行推论,或结果;thus=如此,这样,以此方式;强调用什幺方式或达到某种程度或范围;二、用法不同1、Therefore:会用在句子的开头,或通常都会用在总结一段文章的总结之前.它是一个接续副词,不可以用在连接句字之上。

例如:and therefore He was down with the flu, and therefore couldn't 空白e to the party. 他患了流行性感冒,因此未能前来参加宴会。

2、Thus:有两种词性,2-1 作为接续副词,例如 and thus, 你j也可以用在句子的开头﹐中间或结尾。

例如:Some people are more capable and thus better paid than others.有些人更有能力一些,因此也比别人挣得多。

2-2 作为副词,不可在连接句子之用。

例如:Thus was a new type of advertising born.一种新型广告就这样诞生了。

Therefore和Thus没有哪一个后面必须要加逗号。

拓展资料thereby1、因而;由此;故而,因为某某,从而与某事有关联时用。

很少使用,在英文诗里到可以见到,比较迂腐正规!Our bodies can sweat, thereby losing heat by evaporation.我们的身体能出汗,因而可以通过水分蒸发而降温。

2、在那附近;在不远处。

表示“因此,所以”时so是连词,可以连接两个简单句;而therefore是副词,准确的说是连接性副词,不能直接用来连接两个简单句,它可以放在句首,后面加逗号,也可以放在句中作为插入语。

另外,and therefore 相当于so. 还有therefore常表示很强的推断,用法比较正式,而so则常用于口语中。
