定语从句(Ⅰ)【要点1】　了解定语从句的几个概念:在复合句中修饰名词或代词、起定语作用的从句叫作定语从句。定语从句只作为句子的一个成分,起修饰和说明的作用,不能独立存在。被定语从句修饰的名词或代词叫作先行词。先行词一般出现在定语从句的前面。定语从句由关系词引导,关系词一般有三个作用:(1)连接作用,引导定语从句;(2)代替先行词;(3)在定语从句中充当某一成分。He is the man (whm/that) I saw yesterday.他就是我昨天见到的那个人。(man 为先行词;whm/that为关系代词,在从句中作宾语)
【要点2】　先行词指物时用关系代词which或that。关系代词在定语从句中作主语或宾语,作主语时不可省略,作宾语时可省略。We planted the trees which dn’t need much water.(作主语)The fish(which) I bught were nt fresh.(作宾语)I bught a bk that intrduces Tibet.(作主语)The city(that) he lives in is very far away.(作宾语)
1. All f yu must be very prud.你们一定都为此而感到骄傲。 be prud f 为……而骄傲 be the pride f 是……的骄傲e.g. We are prud f Yang Liwei. Yang Liwei is the pride f us. 2. We have launched anther fur spaceships in the past few years.在过去几年我国又向太空发射了四艘宇宙飞船。 anther fur = fur mre 意为 “又有四个”之意。3.It prves that China has made great prgress in its space industry.这证明中国在航空业已经取得了巨大的进步。 prve v.证明，证实 +从句
3.In a few years, perhaps rbts will think n their wn, just as peple use their brains and act fr themselves.多年以后，也许机器人会有自己的思想，就像人们使用自己的大脑和自己行动一样。 n ne’s wn 独自，单独4.One scientist warns that if rbts start t think fr themselves, they will n lnger want t be ur servants, but ur masters.曾有科学家警告，如果机器人开始自我思考，他们将不再愿意成为我们的仆人，而是想成为我们的主人。warn sb. (nt) t d sth.警告某人（不要）干某事 warn sb. abut sth.提醒、警告某人注意某事 warn sb. against (ding) sth.警告某人某事
