2．On the other hand, there_is_little_doubt_that people with low EQs often have problems getting on with other people and dealing with difficult situations; thus they have a harder time surviving in life.

另一方面，有一点是毫无疑问的：低情商的人在与人交往和对付困难的处境时常会出现问题，因此他们活得更为艰难。

There is little doubt that ...“毫无疑问??”，相当于There's no doubt that ...，否定句用that引导同位语从句。

There is no doubt that he will come to my wedding. 毫无疑问他会来参加我的婚礼。

There is no doubt about ... 毫无疑问?? There is no point in doing ... 做??没有意义 There is no need to do ... 没有必要做??

There is no good/use in doing ... 做??没有好处/用处

The weather report said it would be a fine day tomorrow, so there is no doubt about it. 天气预报说明天会是个好天气，那么就没有疑问了。

There is no need for me to break the window because I have the key. 我没必要打破窗户因为我有钥匙。 [名师指津]

doubt既可作名词也可作动词。当doubt用于肯定句时，后接whether/if引导的宾语从句或同位语从句；当doubt用于否定句和疑问句时，后接that引导的宾语从句或同位语从句。

I doubt if/whether we'll arrive on time. 我怀疑我们能否按时到达。 Do you doubt that it is true? 你怀疑它是真的吗？

I have no doubt that he'll pass the exam. 我不怀疑他会通过考试。

[语法初识]

[语法剖析]

一、过去分词的意义和构成

1．意义：及物动词的过去分词既表示被动也表示完成；不及物动词的过去分词只表示完成，不表示被动。

如：frozen food冷冻食品； boiled water开水

2．构成：规则动词的过去分词是在词尾加-ed，不规则动词的过去分词有其不规则的变化形式。

16

(2)句①中hired, promoted与宾语you之间为逻辑上的被动关系/动宾关系。 (3)句③、句⑦中mistaken和interested为形容化的过去分词，表示主语所处的(被动)状态。 (4)在过去分词作状语的句子中，过去分词分别作：句⑥原因状语；句⑧条件状语；句⑨时间状语。 自主探究 (1)以上课文原句中的过去分词或过去分词短语在句中的作用是：句①宾语补足语；句④、句⑤定语；句③、句⑦表语；句②、句⑥、句⑧状语。 2017-2018学年北师大版高中英语必修5教学案

二、过去分词的用法 1．作定语

及物动词的过去分词作定语表示被动和完成，不及物动词的过去分词只表示完成。

(1)位置：单个过去分词作定语，多放于被修饰词之前；过去分词短语作定语，多放于被修饰词之后。

She has a pleased look on her face. 她的脸上露出了高兴的表情。

He saved every coin, often eating food left. 他节省每一枚硬币，常吃剩饭。

Do you like to read the novels written by Guo Jingming? 你喜欢读郭敬明的小说吗？ [名师指津]

过去分词(短语)作定语常与定语从句互换。 The computer bought last week doesn't work now.

＝ The computer that was bought last week doesn't work now. 上周买的那台电脑现在出故障了。

(2)某些动词的过去分词作定语时，多半用来修饰人。这类过去分词多是表示人物的心理特征或情感变化的动词。如：delighted, devoted, discouraged, amused, astonished, frightened, moved, inspired, encouraged, puzzled, tired, worried, excited等。

The puzzled mother wonders how to deal with her son. 这位困惑的母亲不知道如何应对她的儿子。

→A letter postedyesterday will reach her next week. ②The book given to him is an English novel.

→The book that/whichwasgiventohim is an English novel. ③The frightened horse ran away from the fire.

→The horse that/whichwasfrightened ran away from the fire.

2．作表语

过去分词作表语表示主语的某种性质或状态。

(1)过去分词作表语，除了可以用在系动词be之后，还可用于get, become等后面，表示动作，一般不延续。

She got divorced in 2016, and she had been married to her husband for 8 years by then. 她在2013年离婚，那时她嫁给她丈夫已有8年的时间了。

[名师指津] 许多作表语的过去分词已经演变为形容词，这叫形容词化的过去分词。形容词化的过去分词常用于一些固定短语中。
