I think it is desirable for secondary school students to wear casual clothes when they are at school. Firstly, casual clothes make all students feel comfortable. They don't feel constrained to wear uniform that they do not like. Secondly, for one thing, casual clothes can also give students freedom of choice. They can choose what sizes, colors, and fashions of clothing they love. And for the other, parents do not worry about their clothes because their children can wear any clothing to school as long as it is clean and tidy. It can be said it is the positive aspect for the poor people in the present difficult economic condition. Finally, casual clothes can make students feel self-confident when they are in their favorite clothes. And what's more it makes the school more colorful and lively. In conclusion, in my opinion, all the secondary school students should wear casual clothes. A. Decide whether the following statements are TRUE or FALSE. 1.
