By now, most people know they should be eating more vegetables, but are there ways to get more from the vegetables you already eat? A research shows that when it comes to vegetables, it’s not only how much we eat, but also how we prepare them, that decides the vitamins(维生素) and other nutrients(营养物) that enter our body.

Many studies show that people who eat lots of vegetables have less heart disease, and eye problems and even cancer. But raw(生的) vegetables are not always best. The researchers found that 198 Germans who eat raw food were short of lycopene(番茄红素), the matter found in tomatoes and other red vegetables. “There is an idea that raw foods are always going to be better,” says Steven K. Clinton, a professor at Ohio State University. “For fruits and vegetables, sometimes a little bit of cooking can be helpful.”

A number decide how the vegetables do good to people’s health before they reach the table, including where and how they were grown and stored before being bought. No single cooking way is best. Some nutrients are easily lost in cooking if they are cooked in different ways.

Vitamins C and B are often lost. In January, another report said that boiling was better for carrots than frying(油炸) or serving them raw. Frying was the worst way to cook.

What cooked with the vegetables can also be important? When the vegetables are cooked with fat, the diners can get more nutrients. Fat can also make the taste of vegetables better, meaning that people will eat more of them. Putting some other things will make it taste better — a little salt — can make the food taste better.

D.the fat will increase the nutrition of the vegetables

I love my laptop computer as it holds all of my writing and thoughts. But I know that there are times when I need to move away from these devices (设备) and truly communicate with others.

Once, I teach a course called History Matters for a group of higher education managers. I want students to thoroughly study the material and exchange their ideas with each other in the classroom, I have a rule — no laptops, iPads, phones, etc. When students were told my rule in the class, some of them were not happy.

Most students believe that my reasons for this rule include unpleasant experiences in the past with students misusing technology. There’s a bit of truth to that. Some students think that I am anti-technology. There’s no truth to that at all. I love technology and try to keep up with it so I can teach my students well.

The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversations and truly exchange ideas. I want students to dig deep within themselves for outstanding ideas. I want them to push each other to think differently.

I’ve been teaching my history class in this way for many years and students realize that with deep conversation and challenge, they learn at a level that helps them keep the course material beyond the classroom.

I’m not saying that I won’t ever change my mind about technology use in my history class, but until I hear a really good reason for the change, I’m sticking to my plan. A few hours of technology-free conversation is just too sweet to give up.

1.What were some of the students in the history class unhappy with?

A.the course material B.others’ misuse of technology

C.the writer’s class rule D.discussion topics

2.According to the writer, the use of new technology in the classroom may .

A.help students to better understand historical topics B.keep students from doing independent thing

C.encourage students to have deep conversations D.lead students to misuse the technology.

3.What can we learn from the last paragraph?

A.The writer thinks highly of technology-free conversation in his class.

B.The writer will change his teaching plan soon.

C.The writer will give up teaching history.

D.The writer won’t hold on to his belief.

4.What does the writer wants to tell us?

A.Technology has different influences in different classes in college.

B.Technology makes it difficult to have true communication in class.

C.History classes can help students to develop their deep thinking.

D.It is time for him to give up his teaching method in history class.
