He advised starting early He advised me to start. earlyHe advised that I should start early .二、语法讲解(一)限制性和非限制性定语从句 (1)定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开。This is the house which we bought last month这是我们上个月买的那幢房子。(限制性) The house，which we bought last month，is very nice 这幢房子很漂亮，是我们上个月买的。(非限制性) (2)当先行词被专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的。 Charles Smith，who was my former teacher，retired last year 查理史密斯去年退休了，他曾经是我的老师。 My house，which l bought last year，has got a lovely garden 我去年买的那幢房子带着个漂亮的花园。 This novel，which l have read three times，is very touching 这本小说很感动人，我已经读了三遍。 说明：关系代词that和关系副词why不能引导非限制性定语从句，非限制性定语从句中关系代词和关系副词不可省略。 (-)as和which引导的定语从句 由as，which引导的非限定性定语从句，as和which可代整个主句， 一、which与as引导非限定性定语从句的区别： 1. which只能放在主句后面，而as引导的从句位置相对较灵活，可在前，可在后。 As he realized，I was very useful to him(在前) Air, as we know，is a gas(在中) He was a foreigner，as l know from his accent(在后) He came late again，which made his boss angry(在后) 2当which引导的从句在意义上近乎并列关系时，可以用and this，and that代替，意思是“这件事”。 He changed his mind，which(and this，and that)made me very angry 他改变了主意，这使我很生气。 She has married again，which(and this，and that)was unexpected 出乎意料的是，她又结婚了。 而as主要起与上下文连接的作用，表达说话人的看法、观点，并指出主句内容的出处或根据等。 Einstein，as we know，is famous scientist 爱因斯坦，众所周知，是位伟大的科学家。 As is announced in todays newspaper，we must improve our style of work 今天的报纸上说，我们必须改进工作作风。 3当定语从句位于主句之后，纯粹表示主句所述的内容，不带有“如那样”的意思时，往往用which，而不用as。 They were invited to the state banquet，which was a great honor to them 他们被邀请参加国宴，这对他们来说是莫大的荣幸。 We had to sleep in our wet clothes，which was most unfortable 我们不得不穿着湿衣服睡觉，这简直太不舒服了。 Mummy always treats me just like a baby，which l cant bear妈妈老把我当成小孩子对待，这让我无法忍受。 4当定语从句有“如同那样”的含义时，用as比用which更常见，而这些从句几乎成为固定说法。 Things will turn out contrary to one s wishes，as is often the case 事与愿违，这是常有的事。 As was natural，this inordinate hope was followed by an excessive depression 这种过分希望之后，接着是极度的沮丧，是很自然的事。 Chaucer is buried in“Poets Corner”，as might have been expected 正如人们已经预料的，乔叟被葬在“诗人角”。 The material is elastic，as is shown in the figure 这种材料有弹性，如图所示。 As we know众所周知 as has been said abovebefore正如前文所述 as has been pointed out正如已经指出的 as might be imagined可以想像得到 as anybody can see正如任何人都明白的那样
