1. [问] Look at something else, for example, a TV set. 为什么不说else something呢？
[答] else在修饰不定代词或疑问词时，通常需后置。如：
Don/'t lend the book to anybody else.
What else do you want to say?
2. [问] It is because in the modern world, English is widely used for business between different countries. because 在此句中引导的是什么从句？different countries 在这里指不止两个国家，为什么前面用between, 而不用among 呢？
[答]（1）because 引导的从句放在be动词之后，用作表语。因此，它引导的是一个表语从句。引导表语从句的词还有that，why, what, how等。如：
That/'s why more and more people in China are interested in learning English.
（2）between different countries意为/"在不同国家之间/"。between通常用于表示双方之间的关系，只要构成双方关系，不论数目多少，一律用between。因为句中/"做生意/"是在两国之间进行的，故用between,而不用among。
3． [问] Three quarters of the world/'s books and newspapers are written in English. 与More than three quarters of the information on the Internet is in English too！这两个句子的主语都由three quarters of修饰，为什么第一句的谓语动词用are, 而第二句却用is呢？
[答] 当分数、百分数等后接名词作主语时，谓语动词用单数还是复数，取决于它们后面名词的单复数形式。第一句中的名词books and newspapers是可数名词复数，故谓语动词用are；而第二句中的名词information是不可数名词，所以谓语动词用is。再如：
In our class three fifths of the students are girls.
Ninety percent of the work has been done.
