1.l want to [A ] the answer to the broblem.Could you help me?
A come up with B came up with
C catch up with D come up
解析：come up with 想出,为固定短语.catch up with 赶上,不符题意.to后面要接原型,故B错误,正确答案为A.
2 It is very important [ A ] people to have food and water every day
A for B of C with D about
解析：
It is + adj for sb to do sth做...对...来说很.为固定搭配,当形容词为形容人的品质时介词用of,如：
It is kind of you to help me.
3.He thought of a good way to solve the problem[改为同义句】
He [ came] [ up ] [ with ] a good way to solve the broblem.
解析：理由同选择题一.
祝开心~!
