→Should the school uniform be worn by us every day

manage to do sth与try to do sth的区别
I will manage to give you a surprise on your birthday.(设法做成，重结果）
I will try to give you a surprise on your birthday.（尽力完成，重过程、动作）
Manage to do sth “设法做成某事”强调结果，暗含“做成某事”之意try to do sth“尽力做某事”，表示“尽力做、设法做”强调动作、不表示结果。
C.Parents should give teenagers chances to make their own decisions.句子意思为“父母亲应当给予青少年机会去自己做决定。”
decision为名词,意为“决定、决心”动词为decide,常用短语有 make a decision做决定, make one’s own decision自己做决定,其中 make a decision to do sth=decide to do sth
e.g. I made a decision to study 12 English words every day just now.
= I decided to study 12 English words every day just now.
D.Do you think we must keep teenagers away from the Internet 句子意思为“我们必须的使青少年们远离网吧，你是怎样认为的？”其中keep...away from....意为“使.....远离.....”
