强调句型与形式主语的区别

鉴别It is……句型

“It is…”句型可分为四类: 第一类即“It is(has been) 一段时间 since”。这种类型又可分两种:1.“It is(has been) 一段时间 since 主语 终止性谓语动词”。如果since从句中的谓语动词为终止性动词,则表示自从这个动作发生以来到现在有多长时间了。如:It is(has been)three years since he joined the army.他参军已经三年了。It is(has been)ten years since Tom came to China.汤姆来中国已经十年了。上两句中join,come都是终止性动词,所以表示     

谈谈that引导的从句

that在中学英语课本中出现得较为频繁,作连词时,可以引导多种从句,现归纳如下:一、that引导名词性从句1．引导主语从句that放句首则不能省略,用让作形式主语时,放在后边的主语从句中的that可省略。如:That he has won a gold medal is quite true．It is obvious(that)money doesn’t grow on trees．2．引导宾语从句that引导的宾语从句通常是陈述句。在及物动词hear,say,know,believe和think后面,引导宾语从句的that常常省略。如:I hear(that)he’ll be back in an hour．He said(that)he had already finished his homework．如果宾语从句提前,或动词和从句之间有插入语时,that不可省略;或是几个并列的宾语从句,则第一句中的that可省略,其后的则不能省略。如:That he ever said such a thing I simply don't believe．Just then I noticed,for the first time,that our master was wearing his fine green coat and his black silk capI believe (that) you have done your best and that things will get better．

高二英语语言要点与高考考点（Units 13-15）

[语言要点]1.Whether the other scientists would accept his ideas remained a ques-tion.(BⅡ,P5) 句中连词whether引导的是主语从句。通常情况下,这种主语从句位于句首,即位于谓语动词之前。例如:Whether it is true remains a question.(这件事是否真实,仍是个问题。)若主语从句太长,则整个句子会有“头重脚轻”之嫌,因此,我们常在谓语动词前面用it作形式主语,而把主语从句移到句尾。例如:It remainsa question whether he is able to prove this.(他是否能证明这一点仍然是个问题。)注意:在这种句子中不能用if引导主语从句。误:If we can stay with mymother is another matter.正:Whether we can stay with my mother is anothermater.(我们是不是能和我母亲住在一起,则是另一回事。)

一、They are said to be very good．据说他们很棒。be said后接不定式短语作主语补足语,不定式可视具体情况用一般式、进行式或完成式及被动式,构成“sb,／sth．is(was),said to do／to be doing／to have done／to have been done”结构。该句型可与It is(was)said that…句型转换,故原句可改写为：It is said that they are very good．     

用好“It be 时间”与“since/before/when/that”结构

"It be 时间"与"since/before/when/that结构在中学英语中出现频率较高,是常考的考点。学生们在使用时容易混淆,把握不好,现将这些句式总结如下:1.It be 段时间since…说明:since从句中谓语用一般过去时,主句用一般现在时或现在完成时(即be为is/has been),常译为"到现在为止干某件事有多长时间了";since从句中谓语用过去完成时,主句用一般过去时(即be为     

从高三英语新教材的一条注解谈that引导的定语从句

今年秋季学期刚刚启用的新教材(1997年12月版),高中英语第三册(上)第14课Feedthe World中有这样一个句子:It is thought thatone billion people,that is half the world’s work-ers,earn their living by farmign.该书153页注解1的译文是“一般认为,目前有十亿人,即世界劳动人口的半数是以农业为生的.”对此句作的语法分析是“上句中有两个从句,第一个that引导的从句是主语从句,it是形式主语;第二个that引导的定语从句修饰“one billion people”.笔者认为,注解所给译文是正确的,而把that ishalf the world’s workers看作定语从句是不合适的.

巧辨that从句

that可以用来引导定语从句、主语从句、宾语从句和同位语从句,也可以在强调句中出现。不少同学对这些that从句分辨不清,以致于在平时的作业和考试中出现了一些不该出现的错误。下面笔者结合近几年的高考试题,谈谈如何运用以下四种方法来分辨that从句:一、运用“试减法”,区别强调句型和其他从句如果把句中的it,be和that去掉,把剩余的部分作适当调整后仍然是一个结构完整、意思通顺、合乎逻辑的句子,则该句便是强调句,否则便是其他从句。例如:It was at nine yesterday that we met the film star.将It,was和that去掉后,其余部分可调整为:W…

易混淆的it句型刍议

高中英语中,有许多固定的句型需要识记并加以灵活运用。其中it句型的用法较为复杂,下面笔者对此作一归纳,供大家参考。1.It+be+一段时间+since-clause.该句型表示从从句的谓语动词所表示的动作发生以后到现在、或过去某个时刻所经过的一段时间,意为“自从……以来多久了”。若表示现在的情况,主句多用一般现在时或现在完成时,从句用一般过去时;如果表示过去的情况,主句则用一般过去时,从句用过去完成时。例如:It is/has been3years since his father passed aw ay.他父亲过世已经三年了。Itis/has been2years since w e left school.我们…
