问题描述：
A lot of exercise is good for your health.(译：大量的锻炼对你的身体有好处.）
for your health 在此作状语成份吗?能否写成For your health ,a lot of exercise is good?
Eye exercises are important to students.(译:眼操对学生来说是重要的.)
to students 在此作状语成份吗?能否改写成:Eye exercises are important for students.
答
第一句话中的“for your health”是状语从句,状语从句是起副词作用的,副词用以修饰动词、形容词、其他副词或全句.状语位置放在句首、句中或句末都可以.
第二句话一般搭配是sth. be important to sb./sth. be important for sb. to do sth.
