请把句子补充完整，把合适的选项（A/B）写在横线上。
A. because B. because of
____ the bad weather, we couldn’t see anything below.
The food tasted great ____ I was so hungry.
I stayed up late last night ____ that wonderful show.
Tom didn’t buy that car ____ he didn’t have enough money.
I will stay here for another three days ____ you.
答案
B,A,B,A,B
because和because of都表示“因为”，区别在与because后面接句子，because of接名词，代词或动名词。第一空“the bad weather”为名词词组，所以用because of；第二空“I was so hungry”是一个完整的句子，所以用because；第三空“that wonderful show”为名词词组，所以用because of；第四空，“he didn’t have enough money”为一个完整的句子，所以用because；第五空“you”为代词，所以用because of。
