Unit 2 Colours
Period 3 Grammar
课文呈现
A. Object clauses introduced by that
An object clause functions as the object of a sentence. We use that to introduce an object clause that is a statement.
An object clause can be put after verbs such as know, think, believe, hope and mean.
Grammar
Some people believe that colours can influence our moods.有些人认为颜色会影响我们的情绪。
She hopes that yellow can bring her success.
她希望黄色能给她带来成功。
An object clause can also follow adjectives宾语从句也可以跟在形容词后面
such as certain, sure and glad.
He is glad that the walls in his room are blue.
She is sure that yellow can bring her good luck.
他很高兴他房间的墙壁是蓝色的。她确信黄色能给她带来好运。
在非正式英语中，我们经常放弃这一点。
I think (that) blue is better than pink.
“I’m feeling blue” means(that)“I’m feeling sad”.
Do you think(that)your favourite colour matches your characteristics
Sandy is chatting online with Millie about room colours. Try to add that to each object clause.桑迪正在网上和米莉聊房间的颜色。试着把它添加到每个object子句中。
Millie: Did you know there is a relationship between colours and moods 你知道颜色和情绪之间有关系吗？
Talking about room colours
Sandy: Certainly. I think colours influence our everyday lives in many ways.
Millie : How should we choose the colours for the rooms of a house
Sandy: Most people think light colours are better than dark ones.
Millie: Yes. I notice light colours make rooms seem larger.
常在名词前作定语，由“person（n.）人+-al（形容词后缀）”构成。
Sandy: Sure. I also know blue can make us feel relaxed.
Millie : Yes. My mum says blue is suitable for bedrooms. I also find some people prefer orange for their dining rooms.
Sandy: True, but it depends on personal taste. Anyway, we should choose the colour which makes us feel comfortable.
B. Object clauses introduced by if or whether
We use if or whether to introduce an object clause that expresses a yes/no question. Such an object clause often follows verbs such as ask, see, wonder and find out. The word order in the clause should be the same as that in a statement.
You may wonder if/whether colours influence our moods.
Sandy asks if/whether orange can cheer her up.

语法讲解
that 引导的宾语从句
宾语从句是指一个句子充当宾语，在主句与从句之间有一个引导词。that 引导的宾语从句要注意以下几点：
考点1
引导词本身的省略
连词that引导宾语从句，只起连接主、从句的作用，它本身无意义，在口语或非正式文体中常省略。
e.g. He says(that)he is a Young Pioneer.
他说他是一名少先队员。
语法讲解
考点2
何时使用that 引导的宾语从句
that 引导的宾语从句表示陈述一件事，即由陈述句转化而来。
e.g. He says. He is listening to the weather report.
(合并成主从句)
→He says(that)he is listening to the weather report.
他说他正在听天气预报。
语法讲解
主句的谓语动词是think, hear, hope, wish, remember, forget, know, say, guess 等时，常接that 引导的宾语从句。
e.g. I hope(that)he will be fine soon.
我希望他会很快好起来。
考向1
语法讲解
主句是由“连系动词＋形容词”构成的系表结构，常接that 引导的宾语从句。这类形容词多表示感情，如：happy, glad, pleased, sad, afraid 等等。
e.g. I’m afraid(that)he can’t come.
恐怕他不能来了。
考向2
考点3 that 引导宾语从句的相关内容
考向1 语序
宾语从句用陈述语序，即“主语＋谓语＋其他”。
e.g. Do you think The radio is too noisy.(合并成主从句)
→Do you think(that)the radio is too noisy
你认为收音机太吵吗？
考向2时态
that 引导的宾语从句，主句用一般现在时，从句可以用符合句意要求的任意时态。
e.g. He says(that)they have already returned.
他说他们已经回来了。
He tells me that he was born in 1985.
他告诉我他生于1985 年。
如果主句用一般过去时，从句要用过去时态的某种形式( 一般过去时、过去进行时、过去将来时、过去完成时等)。
He said(that)he had bought a new dictionary.
他说他买了本新词典。
I knew（that）they were studying English.
我知道他们正在学英语。
如果从句表达的是客观事实、真理、自然现象、名言、警句、格言、谚语等等，尽管主句用一般过去时，从句也要用一般现在时。
He said that time is life. 他说时间就是生命。
中考在线1：
—What did you learn in geography class yesterday
—I learned that the sun ________ in the east.
A. was rising B. rises C. rose
B
【点拨】本题用语法判定法。考查宾语从句。句意：—昨天的地理课上你学到了什么？——我学到了太阳从东方升起。当宾语从句表示的是客观真理或客观事实时，从句的时态一律使用一般现在时。“太阳从东方升起”属于客观事实，应用一般现在时。
考点1
if 或whether 引导宾语从句时，作“是否”讲，常放在动词ask, see, wonder, know 和find out 等后面。一般情况下，两者常可换用，在口语中多用if。
［重点］if 或whether 引导的宾语从句
Nobody knows whether / if it will rain tomorrow.
没有人知道明天是否会下雨。
Lucy asked whether / if they had cotton coats.
露西问他们是否有棉外套。
if 或whether 引导宾语从句时，要注意三个方面，即连词、语序和时态。
考点2
if 或whether 不能和that 或其他连词同时使用，也不能省去。
e.g. (误) I don’t know that if/whether he will come here today.
(正) I don’t know if/whether he will come here today.
我不知道他今天是否会来这里。
考向1
(误) He came to see what if /whether there was something wrong with his cat.
(正) He came to see if /whether there was
something wrong with his cat.他走过来看看猫是否有毛病。
考向2
语法讲解
if 或whether 引导宾语从句时，虽具有疑问意义，但从句仍用陈述语序。
e.g. Did you know the way to the hospital
The old woman asked me. （合并成主从句）
→ The old woman asked me if /whether I knew
the way to the hospital.
这位老妇人问我是否知道去医院的路。
中考在线2：
—What did the shopkeeper say to you
—She asked me ________.
A. when does the shop close B. where did I see the style
C. if I preferred that orange dress
D. what else I will buy
C
【点拨】本题用语法判定法。考查宾语从句。句意：—店主对你说什么了？—她问我 。宾语从句用陈述语序，据此排除A、B 两项；主句用过去时，从句也应为过去时的某种形式。
if 或whether 引导的宾语从句应和主句的时态保持一致。即主句为一般现在时，从句用符合句意要求的任意时态；主句为一般过去时，从句则用与过去相关的某种时态。
考向3
I don’t know if /whether he has come here.
我不知道他是否已经来这儿了。
Tom asked if /whether I had read the book.
汤姆问我是否看过这本书。
考向1
在动词不定式之前只能用whether。
e.g. I can’t decide whether to stay.
我不能决定是否留下。
考点3 if 和whether 的区别：
考向2
在whether or not 的固定搭配中。
I want to know whether it’s good news or not.
我想知道它是否是好消息。
考向3
在介词后，只能用whether。
The father is worried about whether he will lose his work.
这位父亲担心他是否会失去工作。
—I am worried about ________ I can enter a good high school or not.
—Take it easy. Believe in yourself!
A. that B. when
C. whether D. where
C
【点拨】本题用词语运用法。上文句意：我担心我能否进入一所好的高中。that 那；when 何时；whether 是否；where 哪里；whether 是否，常与 or not 连用，句中含有or not。故选C。
