16、e is no need for you to earn so much money. . 热点语法：限制性定语从句 一、关联词的基本用法 1、who / that指人，在定语从句中作主语或宾语，作宾语时可省略。 eg: Mr. Blacksmith who / that comes from the USA teaches us English. 2、whom指人，在定语从句中作宾语，可省略。 eg: The boy (whom) he spoke of in his talk was Tom. 3、which / that指物，在定语从句中作主语或宾语，作宾语时可省略。 eg: Footb
17、all is a game which / that is always popular with boys. The pen (that / which) I bought yesterday was lost. 4、whose可指人或物，在定语从句中作定语。 eg: I live in the room whose windows face south. 注意：“whose + 名词”可以转换成“the + 名词 + of which (指物) / whom (指人)”的结构。 eg: The girl whose hair is red is Mary. = The girl, the
18、hair of whom is red, is Mary. 5、when指时间，where指地点，why指原因，三者都在定语从句中作状语，可以转化为“介词 + which”的形式，但是why只能转化为“for which”的形式。 eg: I paid a visit to the factory where / in which I worked ten years ago. 二、限制性定语从句中只用that的情况 1、当先行词是everything，nothing，something，all，none，few，little，some，any等词时，或先行词被every，little，a l
19、ittle，few，much，any，all等词修饰时。 eg: There seems to be nothing that is impossible to him in the world. 2、当先行词被序数词、形容词最高级或the very，the only等词修饰时。 eg: The first place that I visited in Beijing was the Forbidden City. 3、当先行词既有人又有物时。 eg: They are talking about the things and the persons that they met yester
20、day. 4、当主句是以who，which开头的特殊疑问句或先行词是who时。 eg: Who is the man that is lying under the tree? 2 三、what与that的选择 what相当于the thing / place that / which，the person who等，而that只用来指代先行词，只在定语从句中充当一个成分，所以，如果所填或所选择的词需要作两个成分，一般选择what。 eg: They reached what the local people called the Golden Gate. (what = the place
21、that) He is no longer what he used to be ten years ago. (what = the person who) 四、定语从句中的主谓一致 当关系代词在从句中作主语时，从句谓语动词的数原则上要与先行词保持一致，但是要注意以下几点： 1、one of + 复数名词 + 关系代词 + 复数动词。 eg: He is one of the students who have got great success in physics. 2、the / the only one of + 复数名词 + 关系代词 + 动词第三人称单数形式。 eg: He is
22、 the only one of the students who has got great success in physics. 3、as / which引导非限制性定语，代表整个主句时，从句谓语用动词第三人称单数形式。 eg: He decides to get married, which makes his parents very happy. 语法聚焦 1.
