★教材解读★
1.You want to keep your choices open.
这句话的主语是You,want是谓语动词,后面的不定式to keep your choices open作宾语。在不定式中,keep是动词,your choices是宾语,open是形容词作宾语补足语。
choice为可数名词,意为"选择”，复数形式为choices。
open在此处意为“正在考虑的，悬而未决的”。

2.So when you grow up,you can be what you want.
本句是一个含有时间状语从句的复合句。当主句是一般将来时态时,从句用一般现在时表示将来。当主句是祈使句或主句中含有情态动词时，从句要用一般现在时。

3.Do well in school,and the decision will be yours!
◆decision为可数名词,意为 “决定，决议”,复数形式是decisions,可用在短语make a decision中,意为”做出决定”。
[拓展] decision的动词形式为decide,为及物动词,意为“决定”,后面多加不定式或宾语从句。
