1. I'm sure you can find lots of information on the Internet now.
我肯定现在你在互联网上能发现大量的信息。
考点：
(1) be sure的用法：
① be sure+of/about+动名词或名词，意为“确信……，对……有把握”。但在接名词时，be sure of 侧重指主语对某抽象事物的确信无疑；而be sure about则侧重指主语对某具体事物的确信无疑。若后面要接反身代词，则只能用 be sure of, 即 be sure of oneself, 意为“有自信心”。
eg. He is sure of success. 他自信会成功的。
I'm sure of his honesty. 我肯定他是诚实的。
Joan will sit for an important examination nextweek, but she is not sure of herself. 琼下周要参加一个重要考试，但她对自己没有十分把握。
language points
1. I'm sure you can find lots of information on the Internet now.

考点：
② be sure+不定式，表示说话人对句子主语作出的判断，认为句子主语“必定”“必然会”“准会”如何如何。
eg. It is sure to rain. 天一定会下雨。
He is sure to have known about that. 他准是已经知道那件事。
He told me I was sure to get a warm welcome.
他告诉我，说我准会受到热情接待的。
然而 be sure to do用在祈使句中，不是表示判断，而是表示对对方的要求，意为“务必要”“一定要”。

考点：
二、什么是宾语从句(object clause)？
宾语从句就是由一个句子来构成主句的宾语，并有一个连接词引导。

We know Zhong Nanshan．
主语 谓语 宾语

主语 谓语 连接词 宾语从句
宾语从句Object Clause
考点：
三、引导词
1. 陈述句作宾语从句时（包括肯定句和否定句），连词由that引导，因为that在从句中不作任何成分，也没有任何具体意思，因此在口语或非正式文体中常省略。
eg. He said (that) he would like to see the headmaster.
及时练习：1. April is the hottest month of the year.
I believe__________________________________________.
2. It was a little crowded.
I guess______________________________________.

eg. I want to know if (whether) he lives there.
He asked me whether (if) I could help him.
及时练习：3. Does he like sports
Do you know___________________________________
4. Will they play basketball after school
He asks__________________________________________
language points
if / whether he likes sports
if / whether they will play basketball after school
宾语从句Object Clause
考点：
注意：只用whether，不用if的情况如下：
1. whether引导的从句常可以与连词or或or not直接连用。
eg. Let me know whether you can come or not.
2. 当宾语从句提到句首时，只能用whether引导。
eg. Whether it is true or not, I can’t tell.
3. 在动词不定式前面只能用whether。
eg. I don’t know whether to accept or refuse.
4. whether及其引导的成分可放于介词之后，作介词的宾语。
eg. I worry about whether I hurt her feelings.
language points
宾语从句Object Clause
考点：
三、引导词
3. 特殊疑问句做宾语时，用相应的疑问词引导，改为陈述语气即可。
eg. I wonder which tie you like best.
四、宾语从句的语序
宾语从句必须用陈述语序。
句子的两种语序:
1.陈述句结构叫陈述语序 eg. There is a shop near here.
2. 疑问句结构叫疑问语序 eg. Is there a shop near here / What’s near here
language points
宾语从句Object Clause
考点：
五、宾语从句中时态的变化
1.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需要使用任何一种时态。（需要性原则）
2.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。（呼应性原则）
3.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。（特殊性原则）
eg. I hear (that) Jim is a worker. /He said he was sick.
My parents told me (that) the sun is much bigger than the moon.
