解答

1.half of后面要加名词或代词（宾格）,如half of the students,half of the apples,half of us / them等.
2.work as解释为“干...工作”.此句意思是“一周工作三个晚上做匹萨”.
3.修饰形容词要用副词,本题应该用traditionally（而不是直接加y）.再如：The computer is selling at an astonishingly low price.
4.It is important to do sth是个固定句型,It是形式主语,真正主语是to do sth,所以填to make.
by是介词,在介词后面要跟上名词或动词的-ing形式,因此要变成writing.
