5. Lots of scientists are working hard in order to send astronauts to Mars one day. 很多科学家努力工作，就是为了有一天把宇航员送到火星上去。
（1）lots of=a lot of，意为“许多，大量”，既可以修饰可数名词又可修饰不可数名词。
We have lots of books in the library. Is there lots of water on the moon?
（2）in order to do sth.“为了做某事”，表示目的，可位于句首或句中，其否定形式为in order not to do sth.，可与so that引导的目的状语从句进行同义转换。

Unit 2 We have not found life on any other planets yet
1. Scientists think that there has been life on earth for hundreds of millions of years.科学家们认为数亿年以前地球上已有生命存在了。
（1）本句为含有think的主从复合句，即：主语+think+宾语从句
I think it is a good thing.
拓展：当主句的谓语动词是think，believe, suppose等，而主句的主语又是第一人称时，后面宾语从句的否定词常要前移，即否定主句谓语动词。
I don’t think he will come with you.
这咱含有否定前置的宾语从句的复合句变反意疑问句时，附加问句的主谓语要与从句一致。
We don’t think Tom is right, is he?
（2）on earth 意为“世界上；究竟”。
He is the first on earth.
What on earth did you do that for? 你做那究竟为了什么？
拓展：用于强调最高级。He runs fastest on earth.
跟在疑问词之后，加强疑问。Why on earth did you tell a lie?
加强否定：一点也......
No use on earth.一点也没有用。
辨析：on earth和on the earth
前者表示“世界上”，与 in the world同义。后者表示“在地球上”。
I must be the happiest person on earth. We live on the earth.
2. The sun and its planets are called the solar system.太阳和它的行星被叫做太阳系......
本句是一个被动语态的句子，主语是动作的承受者而非执行者。一般现在时的被动语态的构成：am/is/are+及物动词的过去分词。
The room is often cleaned by us. The boys are often taken to the workplace by their parents.
助记：巧记主动变被动：
宾语提前主语变，时态人称be关键。过去分词勿变错，原主变宾by后见。

4. They are very far away and their light has to travel for many years to reach us.它们离我们很遥远，它们的光必须要经过许多年才能到达地球。
He didn’t stop until he reached the door.他到门口才停止。reach及物动词，“到达”。

拓展：enough作adj.修饰名词时，可以放在名词前，也可以放在名词后，通常放在名词前，但enough作adv.修饰adj./adv./v.时，总是放在修饰词之后。

6. With so many stars in the universe, are we alone, or is there life out there in space?宇宙中有这么多的星球，我们到底是孤单的呢，还是太空中还有其它生命存在呢？
