when they visit someone. Different flowers
have different meanings. For example,
people often give red roses to someone they
love. In Greece, you must not give white
flowers because that means that someone is dead.

Modal verbs
每天要完成什么要完成多少，
完成以后才可以休息，
每天完成定量的功课，
既能增强自己学习的信心，
也能养成良好的学习习惯
6、要把功课一科一科的完成
学习最大忌讳，就是哪科都做了，但哪科都没有收获，就像看书一样，书不在一天看得很多，而在于书上的内容你是否真的记住了，理解了。
学习不在于你一节课学习了几科，而在于你每学一科，是否有收获。所以同学们要一科一科把功课认真完成，而不要学着这科想着那科。
