定语从句与强调句句式结构用法比较 由it引导的句型结构,常可构成强调句或定语从句,两者极易混淆。一般来说,如果将it is/was...与连接词去掉,句子仍然正确,就为强调句型。这时,就选用that连接词;否则,就为定语从句,其关系词的选择,应根据先行词与从句的关系而定。 例1. (1) It is on the island that they spent 10 years. (2) It is the island where (on which) they spent 10 years. 比较:(1)该句为强调句。表示地点的名词the island前有介词与其连用,说明它是一个完整的地点状语。如果将it is去掉:They spent 10 years on the island.它的意义仍然完整。故应选用连接词that构成强调句式 (注:强调地点状语时,不可用where连接)。 (2)该句为定语从句。表示地点的名词the island前没有介词与其连用,说明它不是一个完整的地点状语。如果将it is去掉:They spent 10 years the island.它的意义不完整。故应选用关系副词where或on which 构成定语从句结构。 例2. (1) It is on the date that she went abroad. (2) It is the date when(on which) she went abroad. 比较:(1)分析句子结构可知,在表示时间的名词the date 前有介词与其连用,说明它是一个完整的时间状语。如果将it is去掉:She went abroad on the date.它的意义仍然完整。故应选用连接词that构成强调句式(强调时间状语时,不可用when连接)。 (2) 分析句子结构可知,在表示时间的名词the date 前没有介词与其连用,说明它不是一个完整的时间状语。如果将it is去掉:She went abroad the date.它的意义不完整。热心网友 时间:2023-07-05 17:28
首先,定语从句还有另外一个名称——形容词从句,其目的是修饰名词即先导词,这是定语从句的特点,没有先导词,定语从句就失去存在的意义。二者缺一不可。
其次,强调句顾名思义就是要强调句中某个成份,通常是主语、宾语或状语。与定语从句容易混淆的是其中一种常见格式,It is(was) ... that(who, whom) ... ,其特点是强调那部份,就到 that 前面做 it is 的受词。如:
It is John who/that broke the window yesterday.
It is the window that John broke yesterday.
It is yesterday that John broke the window.
1. 强调句与主语从句的比较
强调句将句子中的it is / was…that同时省去,句子仍然成立;而主语从句将that与后面部分代替it,成立。如:
(1) It is Li Lei’s brother that you met in the street yesterday. 你昨天在街上所见到的就是李蕾的兄弟。
本句若将It is 及 that同时省去为:You met Li Lei’s brother in the street yesterday. 句子同样成立,因此前面的句子是强调句型。
(2) It is exciting that we have succeeded in sending up Shenzhou V. 我们成功地发*神舟五号这件事情真令人兴奋。
本句若将It is 及 that同时省去为:We have succeeded exciting in sending up Shenzhou V. 显然句子错误,因此,前面句子不是强调句型,而是主语从句。
2. 强调句与定语从句的比较
强调句中的It没有实际意义,It be与that可同时被省略;而定语从句中的It是主语,It be与that不可同时省略;
强调句型中be的时态须跟后面句子的时态相一致;而定语从句中主句谓语动词be的时态须由主句的时间确定;
强调句将句子中的that不能省略,并且即使前面的名词是事物时,也不能将that换成which;而定语从句中的that作宾语时可被省略,并且当先行词是事物时可用which代替。
当it be后面的时间、地点名词作主语、宾语或表语时,引导词可用that / which;而作其他成分时,引导词须用when / which。如:
(1) It is an English book (that / which) I bought yesterday. 它是我昨天买的书。(本句是对What is that?问句的回答,that所引导的是定语从句,that可被省略)
It was the English book that I bought yesterday. 昨天我所卖的就是这本书。(本句相当于对I bought the English book yesterday中an English book进行强调)
(2) It was a room where we used to have meetings. 它是我们过去常在开会的房子。(where 所引导的从句对前面的room进行说明,它是定语从句)
It was in the room that we used to have meetings. 过去我们开会就在这间房子里。(in the room是被强调的部分,本句是强调句型)
(3) It is a day when the people celebrate their victory. 这是人们庆祝他们的胜利的日子。 (when所引导的从句对a day进行说明,是定语从句)
It was on that day that people celebrated their victory. 就在那一天,人们庆祝了他们的胜利。(强调on October 1, 1949)

其实强调句和定语从句的区别还是很明显的。热心网友 时间:2023-07-05 17:30
连接词的选用依具体情况而定,which等等;而定语从句这不是,它还可以用whoes;who(指人):it
