`1.` pizza:

`-` I think students should prepare it because pizza is a popular dish and can satisfy many people's culinary preferences. Not only that, students can also easily order food from nearby restaurants or pizza stands at very affordable prices, which saves a lot of time!

`-` should + V0: nên làm gì.

`2.` soup

`-` At a student party, you shouldn't prepare this dish because soup is a dish that takes a lot of time to make and can cause a fire when the cooker is used incorrectly. Besides, soup may not suit each student's taste.

`-` because: bởi vì (chỉ lý do) 

`3.` snack, candy

`-` Students love to eat sweets, so preparing snacks and candies is reasonable. They are also snacks that can bring joy to students. They can buy snacks and candies at grocery stores, supermarkets or snack stores without requiring too much effort in preparation.

`5.` bread, cheese.

`-` This is not a good idea because bread and cheese are bland and uninteresting to students. It spills all over the floor and is difficult to clean up. Besides, if you don't eat it all, leaving it behind is a waste.

`-` and là từ nối (chỉ 2 vế tương đương nhau)

`6.` fruit.

`-` In my opinion, preparing fruit is necessary because fruit is a healthy food. Not only that, it is also a "beverage" after students eat sweets. Besides, it also creates balance for the menu and is suitable for many students. 

`-` In my opinion: Theo quan điểm của tôi. 

`-` because: bởi vì (chỉ lý do)
