解答 Students in our school have held a heated discussion about whether it is necessary to hold parties to celebrate different festivals．Opinions vary from person to person．（引出主题）
Some students are in favor of the activities，which they think make their after-class life colorful and thus relieve some study pressure．（高分句型1）Besides，not only does holding activities help them know each other better but it improves their abilities．What's more，some can display themselves and earn respect．（赞成及其原因）
However，some students hold a different view．Firstly，it will take a lot of time to rehearse，which affects their study．Secondly，the list of performance is limited and only a small number of students have the opportunity to take part in it．Thirdly，a lot of waste is produced after the activity，which is harmful to the environment．（反对及其原因）
Personally，I think it is good to hold parties，in which I can always enjoy myself and get relaxed．（高分句型2）At the same time，our classmates may have a really great time by enjoying my performance．（作者的看法及原因）

The image above embodies what is referred to as cooperation and win-win situation，the significance of which，from where I stand，cannot be overrated．（高分句型一）
Only then were we aware that the duties could have been allocated based on what each member exceled at．（高分句型二）

解答 Held in four hands are four irregular shaped jigsaws，with some parts sticking out and some cut off．But when pieced together，they constitute a flawless and crackless square．The image above embodies what is referred to as cooperation and win-win situation，the significance of which，from where I stand，cannot be overrated．（高分句型一）
　　Indeed，it is through working collaboratively that we can get a clear picture of our virtues and drawbacks．Once my learning group was assigned a presentation task covering three sections．We had planned to work on each section separately，but during the rehearsal phase problems like computer illiteracy，lack of fluency popped out．Only then were we aware that the duties could have been allocated based on what each member exceled at．（高分句型二）
　　More importantly，it pays to put aside disputes and seek common development instead．True，it is that competing interests and conflicting desires prevail universally，but history has witnessed the long term joint effort between opposing sides，particularly political parties．（高分句型三）For instance，the Democrats have long been working in partnership with the Republicans，both committed to reviving US economy and striving for citizens'welfare．
　　As social beings，we can hardly exist alone in society．United we stand，divided we fail．
