Some people buy food that is already prepared.Other people buy fresh food and prepare meals themselves.Which do you prefer? Explain why, using details and examples in your answer.
有些人购买已经准备好的食物。其他人购买新鲜食物自己准备饭菜。你更喜欢哪个？解释为什么，在你的答案中使用具体示例详述。
I prefer to buy ingredients myself and cook for myself.First of all, cooking is fun and I am gonna exercise my cooking skills in the process.Choosing fresh vegetables, meats and dairy products from the supermarket is a great diversion for me after a long day's study, which is so relaxing; plus I really enjoy checking recipes online and learning to do great dishes myself, and I think taking good care of ourselves and eating properly is crucial.Second, it's more economical to cook at home.The ingredients are simply much cheaper than prepared food.We can learn to budget and save quite a lot of money.At the same time, the fresh food is much healthier and has more nutritional benefits.
我更喜欢自己买食材，自己做饭。首先，烹饪很有趣，我将在此过程中锻炼我的烹饪技巧。在漫长的一天学习之后，从超市挑选新鲜的蔬菜、肉类和乳制品对我来说是一个很好的消遣，这太令人放松了；另外，我真的很喜欢在网上查食谱，自己学习做可口的菜肴，我认为照顾好自己和健康饮食至关重要。其次，在家做饭更实惠。这些原料比准备好的食物便宜得多，我们可以学着节制消费并省下很多钱。同时，新鲜的食物更健康，营养益处更多。

The student proposes that the school should allow students to use laptops in class coz students can take notes faster on a computer so they pay more attention to the lectures.Also, professors could direct students to view websites with useful information.The man in the conversation disagrees with this proposal.Firstly, he points out that with laptop computers, students will in fact pay less attention to the professor's lecture, for example, they will surf the Internet, play computer games, or email people.Secondly, he says that not every student has a laptop computer, and not everyone could follow along.So laptops cannot be an effective teaching tool if only some of the students have it while others don't.

The professor explains how snails survive in hot and dry climates.The first strategy is to avoid heat.The snail would move into the shelter of vegetation in high temperatures to get out of the sun.Also, during a hot day, the ground can be very hot since it absorbs and radiates heat.So the snail would attach itself to a wall or tree where it is cooler than the ground.The second strategy is to avoid drying out due to lack of water.The snail would secrete a sticky slimy substance made up of calcium, which covers the opening of its shell and closes it up, so it could keep moisture inside it and stay inside the shell for several months without food as its body will slow down.Later, when it rains, the snail opens up its shell and gets the water it needs.
