语法指导；掌握四级代名词

        除了单数代名词，英文中也有复数代名词“many, both, several, few”等；其用法和复数名词一样，跟着的也是复数动词，如：
        　　
        　　⑩ Many were absent yesterday.
        　　
        　　11. Few are welcome here.
        　　
        　　此外，有些代名词，如“some, all, none, any”等，既可当单数，也可当复数，一切视上下文而定。例如：
        　　
        　　12a. Please look at the old office equipment. Some is to be replaced.
        　　
        　　b. Some of them have agreed to come.
        　　
        　　13a. All is well that ends well.
        　　
        　　b. There are twenty in the bus. All have arrived on time.
        　　
        　　14a. None of the news was good.
        　　
        　　b. None of her friends phone her now.
        　　
        　　在英文词类中，代名词是简单容易的一种，但是也好像容易犯错；希望大家不要掉以轻心，以免犯下同样的错误。
