When it comes to eating, we have strong habits. But most of the habits are not good for us. Let's read the following rules. They can help you eat well and stay healthy.

Eat all kinds of foods. We all know that eating fruit and vegetables can help us stay healthy. but many of us only eat our favorite food. Remember that we can only get the nutrition we need by eating different kinds of foods. There are five main types of healthy foods, they are fruit, vegetables, whole grains(谷物), protein(蛋白质) and low-fat dairy products(奶制品)

Drink water and milk most often. Everyone knows that water is important. Adults should drink 2-3 liters of water per day, while children should drink 12 liters. Besides that, kids need plenty of calcium lo grow strong bones, and milk has a lot of it. Every day, you should drink at least three cups of milk, when you are 9 years old or older, you should also try to have less sugary drinks, like soda and coca. Sugar just adds calories(卡路里), not important nutrition .

Listen to your body, when you are eating. Notice how your body feels. When your stomach feels comfortably full, stop eating. Eating too much makes you feel uncomfortable. If you do it too often. it can make you unhealthy and fat. When you eat, you should eat slowly. If you eat too quickly, you may "clean your plate" instead of paying attention to whether your stomach feels full.

Be smart about your dinner. A good time for a healthy evening meal is between 17: 00 and 20: 00. Food provides us with energy, and at night your body simply doesn't need any, It's best to avoid late night snacks because they fill you with unnecessary calories and can disrupt(扰乱)your sleep.

1.How can people get the nutrition?

2.How much milk should a 9-year-old boy drink every day?

3.When should people stop eating?

4.Why should people avoid late night snacks?

5.What’s the passage mainly about?

Old habits, especially bad ones, can be hard to break.

People often make fun of New Year's resolutions (决心). However, resolutions present a big opportunity for self-improvement. Fortunately, social science has some ideas about how to start a good habit and stick to it.

Gary Charness and Uri Gneezy, two scientists at the University of Chicago, did some research, where 120 students were asked to take part in an experiment about exercise habits, and each of them would get $175 in the end. The students were randomly assigned (随机分配)　 to three groups. The first group got the money for just giving researchers permission (允许) to record their gym attendance (出勤). The second group gave permission, but had to go to the gym at least once the next month. The final group gave permission and had to go to the gym eight times that month.

Unsurprisingly, the group that had to make eight gym visits to get paid exercised more than the other two groups. After the payments stopped, these students kept going to the gym at higher rates (频率). They went to the gym about twice as often as the other two groups.

In another study, researchers invited 151 students to work out in the gym, and randomly assigned 75 to a "temptation-bundling" group. As they exercised, they listened to the start of an attractive audio-novel (有声小说).At the end of their workout, students were told that if they wanted to hear what happened next in their book, they would have to come back to the gym .They could only listen to the audio-book while exercising. The other 76 students also completed the first workout but without any kind of temptation bundle.

It turned out that the students in the temptation-bundling group visited the gym 27% more often than the control group over the next seven weeks. Sadly, the temptation-bundling trick fell apart over the Thanksgiving holiday when the gym was closed.

The studies show that trying something new quite often for as little as a month can kick-start a lasting change in behavior. Moreover, "temptation-bundling" may also be a useful method for changing behavior, particularly when used together with other methods. Even if you cannot promise yourself to stick with something for long, there is a huge benefit in putting in a lot of energy for a few weeks. It may pay off for longer than you think. So, why not challenge yourself with next New Year's resolution?

1.What can we learn from the two studies?

A.The students got different payments according to their gym attendance.

B.The temptation-bundling group loved audio-novels more than the other group.

C.The students who exercised more often at first were more likely to keep working out.

D.27% of students in the temptation-bundling group exercised more often than before.

2.The third paragraph is mainly about ________.

A.what was found in the research

B.how the research was performed

C.why the scientists did the research

D.who took part in the research

3.The underlined word "temptation-bundling" in Paragraph 5 probably means ________.

A.forming new habits by trying something you didn't like before

B.pushing yourself by doing two tasks at the same time

C.improving your workout skills by listening to audio-books

D.connecting something you like with something you have to do

4.What is the writer's main purpose in writing this passage?

A.To encourage people to go to the gym more often.

B.To present a new way to do scientific research.

C.To offer advice on how to develop a good habit.

D.To stress the importance of New Year's resolutions.
