宾语从句就是用一个句子来构成主句的宾语
D yu knw wh is the first Chinese astrnaut (宇航员)?Our teacher tld us that the earth ges arund the sun.Please tell me where she has gne.I dn’t knw if he will cme tnight.Let’s find ut what’s n tnight .
Find ut the Object Clauses
注：that 在句中无词汇意义，在从句中不能充当成分，在口语当中往往省略。
e.g. ►I hear (that) he will be back in an hur.►He said (that) he missed us very much.
1.由从属连词that引导的宾语从句
a. 在主+谓+it(形式宾语)+宾补+that 从句(真正宾语) 的句型中不省略。►We must make it clear that we mean what we say.b. 由连词and连接的两个由that引导的宾语从句中,第二个that 不省略。►He tld me（ that）he wuld cme and that he wuld cme n time.
that在宾语从句中的省略与保留
c.当that作介词 except, in等宾语时。►They believe in that she must still be single.►I knw nthing abut him except that he is living in Beijing.
2.由从属连词 whether, if 引导的宾语从句。
►I want t knw if/whether she is right .►They didn’t knw whether Tm culd cme back r nt .
if/whether 引导宾语从句 表示“是否”。 if/whether可互换，但whether…r nt为固定搭配。
1).whether和if都可以引导宾语从句 ►I dn’t knw whether r nt he will cme. 如果r nt放在whether所引导的从句句尾，可用if 替换。 ►I dn’t knw whether/if he will cme r nt. ►I wrry abut whether I hurt her feeling.
注意whether和if的使用区别
a.当whether后紧跟r nt时，不用if.
b.介词后面的宾语从句不能用if.
►He asked me whether I wanted t g there by train r by bus.他问我是想乘火车还是坐公共汽车去那里。还有“不管”之意，引导让步状语从句。►Whether he drives r takes the train, he will be here n time. 不管开车来还是乘火车来，他都会准时到。
c.在强调任意选择时，用whether…r，此时不用 if 替换whether。
►He asked me whether I’d mve t New Yrk if I gt the jb.
d. 虽引导宾语从句，但为了强调宾语部分，也可把从句放在句首，此时只用whether不用if。
►Whether he will cme I am nt sure.
e.句子中有if 引导的条件句，如再有表示“是否”的宾语从句，用whether不用if。
►Please let me knw if yu need help. 如果你需要帮助请告诉我。或：请告诉我你是否需要帮助。对比： ►Please let me knw whether yu need help. 请告诉我你是否需要帮助。
f. 容易产生歧义时用whether不用if来表示“是否”。
►I dn’t knw if it wn't rain tmrrw. 我不知道明天是不是会下雨。
g. 如果宾语从句为否定句时，则只用if不用 whether。
2).引导主语从句置于句首时，只能用whether。►Whether he cmes r nt makes n difference. 3). Whether可以引导表语从句和同位语从句，if不可以。4).用在动词不定式之前时用whether不用if。 ► I dn’t knw whether t g there at nce. 我不知道是不是该立刻去那里。
3.由连接代词 wh, whm, whse, which, what 和连接副词 where, hw, why, when引导的宾语从句
►D yu knw whse bk it is ?►Please tell me when we’ll have a meeting .► Culd yu tell me why the train is late?►He asked wh culd answer the questin.
当主句是一般现在时，宾语从句的时态不作限制，我们可以根据句子的意思来使用需要的任何一种时态。
He will g t Hng Kng .He is sick.He is reading a bk . He has finished his wrk.
He had finished his wrk.
He wuld g t Hng Kng .
He was sick.
He was reading a bk .
当主句是一般过去时的时候，宾语从句必须运用相应的过去的某一种时态，从而达到主句和从句的相互一致。
the sun is much bigger than the mn .
Summer is after Spring .
the earth mves arund the sun.
He tld me (that)
We kmew (that)
The teacher tld us (that)
当宾语从句说明的是客观存在的事实或者是客观存在的真理时，就不用受到主句时态的限制，仍是用一般现在时态。
►Danny says that he will learn English. ►D yu knw where he came frm? ►Please tell me hw I can get t the bus statin .
无论主句是陈述句还是疑问句，宾语从句都是运用陈述句的语序，即是“主语在前，谓语在后”的顺序。
if／whether+一般疑问句
特殊疑问词+特殊疑问句
一般过去时过去将来时过去进行时过去完成时
宾语从句的语序都为陈述句语序
学习宾从三注意，时态语序和连词。时态主从要呼应：主句若为现在时，从句时态随句意；主句若为过去时，从句时态变过去；宾从若是表真理，时态不变无质疑。语序要用陈述序，切莫照搬疑问句。That 连接陈述句，省与不省要注意。从句若表“是否”时，if/whether要慎记。特殊问句作宾语，仍用原来疑问词。三个问题需牢记，切莫丢东忘了西。
所谓感叹句，就是用来表达喜怒哀乐等强烈情感的句子。近年来，感叹句的构成及转换是中考常考的考点之一。感叹句一般由“what”和“hw”来开头的句子 “what”修饰名词，“hw”修饰形容词和副词。
What 和 Hw引导的感叹句
What 引导的感叹句
“what”意为“多么”用作定语，修饰名词（被强调部分），名词前可有其它定语成份（即：形容词或冠词）。单数可数名词前要加不定冠词a/an，复数可数名词或不可数名词前不用冠词。
一般有三种形式，此时what为形容词，作定语，用来修饰它后面的名词或词组。 1. what+a/an+形容词+可数名词单数+主语+谓语！►What an interesting stry it is! 多么有趣的故事呀！ ►What a gd girl she is! 她是个多么好的一个女孩啊！
2. what+形容词+不可数名词+主语+谓语！ ►What heavy snw it is! 多么大的雪呀！►What bad weather it is! 多么糟糕的天气！ 3. what+形容词+可数名词复数+主语+谓语!►What beautiful flwers they are! 多么漂亮的花啊！► What gd students they are! 他们是多么好的学生啊！
“hw”意为“多么”，用作状语，修饰形容词或副词（被强调部分）。如果修饰形容词，则句中的谓语动词用系动词；如果hw修饰副词，则句中的谓语动词用行为动词。
有三种结构形式。此时hw是副词，用来修饰其的形容词 或副词，也可以修饰动词。1. Hw+形容词+主语+谓语！例如： ►Hw cld it is tday! 今天多么冷呀！ ►Hw ht it is tday!　 今天多么热呀！
2. Hw+副词+主语+谓语！　例如： ►Hw happy they lk! 他们显得多么高兴呀！►Hw fast he runs! 他跑得多么快呀！ 3. Hw+主语+谓语（陈述句）！例如：►Hw he lves his sn!他是多么的爱他的儿子！►Hw time flies! 光阴似箭！
what修饰名词What +名词+陈述语序What+a+形容词+名词+ 陈述语序What+ 形容词+复数名词+ 陈述语序What+ 形容词+不可数名词+ 陈述语序
hw 修饰形容词，副词或动词:Hw +形容词+ a +名词+ 陈述语序 Hw+形容词或副词+ 陈述语序
