第一节:阅读表达

We all know eating out can be a lot of fun. There’s the experience of having someone wait on your every need,the social aspect of being in a restaurant with friends and,of course,the great benefit of the lack of in—home cleanup.

2We all also know eating out can be expensive,and I’m pretty sure college isn’t the most

financially successful time in a normal person’s life. That’s why eating at home for a majority of meals really is the only option for many college students.   

Eating at home doesn’t have to be dull,boring,or difficult. —It can and should be an energetic,creative experience that transforms the way you look at food. When you cook for yourself, you know exactly how your pasta(意大利面)is going to turn out. You know where the greens in your salad come from. You know the olive oil you’re using really comes from olives that are pressed for the first time. Use eating at home as all opportunity to learn and develop your kitchen skills. I promise you they will remain useful and rewarding for the rest of your life.

Another important concept is to keep in mind that when it comes to shopping for food—less quantity, more quality. Buy base ingredients that are fresh,as local as possible and beautiful,and anything you cook will improve greatly. I promise you will be just as satisfied by eating a little bit less of something with a lot more quality.

I am not saying eating out is a bad thing. But I insist there are many more places that are not worth your cash. Put a little more effort into cooking for yourself at home and you will gain experience and appreciation for the world of food.
