（1）that they need定语从句，修饰先行词information。关系代词只用that而不用which，因为当先行词之前有不定代词all，any，every，no，some等修饰时或先行词本身就是不定代词（如anything，something，nothing，all等）时，其后的定语从句常用关系代词引导。如果that在定语从句中作宾语，that可以省略。
Have you got any book that interests you much? 你有没有使你感兴趣的书？
2）look up
A．查阅；查找
If there are words you dont understand, look them up in the dictionary．如果有不认识的词，就查字典。

B．看望
Dont forget to look me up when you come to Beijing．到了北京别忘了来看我。
6．work at, work on的区别
work on sth．中sth．是work的具体对象，work at sth．中sth．只说明所从事工作的性质（即时间、精力用在某一方面的事情上），而不在于说明正在做什么。如：
When the boy saw the soldiers, he stopped working on the branch, stood up, and took off his cap. 小男孩看到了这些士兵，便停止了削树枝，站了起来，取下帽子。（树枝是具体的对象）
work on还表示“继续工作”“努力影响或努力说服”。
Can you work on him to make him change his mind? 你能努力说服他改变主意吗？

B. Its time for class. Please stop to listen to the teacher．上课了，请停止讲话，听老师讲课。
2）start working开始工作
start，begin，continue这几个动词后接动名词和动词不定式意义基本一样。但start，begin这两个动词要注意下列用法：
A．句中主语是物而不是人时，其后最好跟不定式。
The ice began/started to melt．冰开始化了。
B．当begin，start本身为-ing形式时，其后应跟不定式。
Im beginning/starting to cook the dinner．我正要做饭。
C．其后的动词是情感动词或是与智力相关的动词如understand; realize; wonder; forget, remember; know; like; love等时也应用不定式形式。如：
I’m began to understand what he had done that for．我开始明白了他原来为什么做那件事。
