1 . Picture the scene: It’s midnight. You’re very hungry after studying for a long time. Then you see a nice pie in the fridge. Will you eat it? It seems that you shouldn’t, for many reasons, including its influence on your studies.
Scientists have long known that eating late at night can make us put on weight. But now a new study has shown that late night eating can also have a bad influence on our brains—it might hurt our ability to learn new things and store memories.
“We believe that late night eating may have an influence on the parts of the brain that control learning and memory,” Dawn Loh, PhD, a scientist at the University of California, Los Angeles, said, “We believe the timing of when we eat may be the main cause of the damaged memory. ”
For the study, the researchers did an experiment. They looked at two groups of mice with strict feeding plans. For two weeks, the mice were allowed to eat either during the time when they are usually the most active, or during the time when they usually sleep. The mice received the same amount of sleep and calories.
Then the researchers tested the brains of the mice. In one test, the scientists tried to find out whether the mice had a good memory by putting the mice in a room connected to an electric shock for some time. The researchers noticed that, when the mice were put in the room again after 24 hours had gone by, those mice that ate when they should have been sleeping were less scared than those mice that ate during usual hours. It means that they didn’t remember.
So think twice before the midnight snack—it might be bad for more than your weight.

3 . Do you know mukbang (吃播)? It is about the eating shows in front of the camera on the Internet. In the shows, mukbangers eat food and sometimes talk to people who watch their videos.
The eating shows started in South Korea in around 2010 and then became popular all over the world. Why did mukbang start in this country? The reason is that eating alone is quite common in the country. Watching mukbang can be a way to have someone to eat with, even though they are at home alone. This is one of the reasons why many people around the world like watching mukbang.
However, the way mukbangers eat food in some shows is not healthy. These bad eating habits can bring serious health problems. To have more fans and make more money, some mukbangers prepare a lot of food in front of them. But they throw away much food secretly during the show or throw up food after the show to make viewers believe they have eaten up everything. These mukbangers waste a lot of food.

4 . What’s the best thing to eat on a hot summer day? Quite a few people will say it is ice-cream. Yes, eating ice-cream with some fruit is a good way to cool down. But think before you eat. If you feel hot from playing sports, it's not the best time to eat ice-cream. If you eat ice-cream when you feel hot, it may give your stomach some problems, and you may get diarrhoea (腹泻). You can eat some ice-cream after you cool down. Just try not to eat too much at a time!
People shouldn’t eat or drink anything cold just after dinner. If you want to stay cool and healthy, oranges, bananas and pears can help.
In summer, germs (细菌) grow very fast and food goes bad easily. You should eat clean and fresh food. When you want to eat a cold dish, put in some vinegar (醋) to disinfect (杀菌) it. If you can’t finish your food and want to eat it again the next day, you should heat it enough to kill the germs in it before you eat it.

7 . We always discuss about health, especially for kids. But what is health? “Health” means eating well, getting enough exercise, and having a healthy weight. Let’s read the following rules. They can help us stay healthy.
Eat a variety of foods, especially fruit and vegetables. We all know that eating fruit and vegetables can help us stay healthy, but many of us only eat our favorite foods. Remember that we can only get the nutrition (营养) we need by eating different kinds of food, especially fruit and vegetables.
Drink water and milk most often. Everyone knows that water is important. Besides that, kids need plenty of calcium (钙) to grow strong bones, and milk has a lot of it. Every day, we should drink at least three cups of milk (1,300 milligrams of calcium) when we are 9 years old or older. We should also try to have less sugary drinks, like soda and coca. They include a lot of added sugar. Sugar just adds calories (卡路里), not important nutrition.
Listen to our body. When we are eating, notice how our bodies feel. When our stomachs feel comfortably full, stop eating. Eating too much makes us feel uncomfortable. If we do it too often, it can make us unhealthy and fat.
Limit screen time. What’s screen time? It’s the amount of time we spend watching TV, movies, and playing computer games. The more time we spend on these sitting-down activities, the less time we spend playing sports, like basketball, and doing other activities like bike riding and swimming. Try to spend no more than 2 hours a day on screen time.
1. The underlined phrase “a variety of ” means ________.| A．相同的 | B．各种各样的 | C．一种 | D．许多 |
| A．We should play sports as much as possible. |
| B．We should spend less than two hours on digital media (电子产品). |
| C．Playing sports is more important than sitting-down activities. |
| D．Screen time includes the time of watching TV, movies and playing computer games. |
A． | B． | C． | D． |
| A．How to Eat Healthily. | B．Drinking Is Important. |
| C．Health Is Very Important. | D．Rules for Staying Healthy. |
8 . Healthy eating doesn’t just mean what you eat, but how you eat. Here is some advice on healthy eating.
Eat with others. It can help you to see others’ healthy eating habits. If you usually eat with your parents, you will find the food you eat is more delicious.
Listen to your body. Ask yourself if you are really hungry. Have a glass of water to see if you are thirsty—sometimes you are just thirsty, and you need no food. Stop eating before you feel full.
Eat breakfast. Breakfast is the most important meal of the day. Since you don’t eat for the past ten hours, your body needs food to get you going, so you must eat something for breakfast. You will be smarter after eating breakfast.
Eat healthy snacks (点心) like fruit, yogurt (酸奶) or cheese. We all need snacks sometimes. In fact, it is a good idea to eat two healthy snacks between your three meals. This doesn’t mean you can eat a bag of chips.
Don’t eat dinner late. With our busy life, we always put off eating dinner until the last minute. You’d better eat dinner at least 3 hours before you go to bed. This will give your body a chance to digest most of the food before you rest for the next 8—10 hours.

9 . ①Should we eat more meat or more vegetarian food (素食)? A recent study shows that there are more vegetarians (素食主义者). People become vegetarians for different reasons. Some choose a vegetarian diet because they believe killing animals is wrong. People who care about their health see it as a good way to keep fit and lower their risk of many illnesses. Lately, more people are having vegetables instead of meat because being vegetarians plays an important role in protecting the environment.
②For further research, researchers from China gave a report about the influence of eating behavior on the environment. It showed that meat consumption is one of the main ways that humans can harm the environment, second only to the use of cars. But how can changing our diets make a difference? We can compare the amount of water needed to produce meat and crops (农作物). For example, we need almost 20,000 liters (升) of water to produce a kilo of beef, but only about 150 liters of water are needed to produce a kilo of crops. It’s clear that we can make better use of land and water if we produce crops instead of meat.
③Feeding animals for food also leads to the rise of global temperatures. Animals such as cows, pigs and sheep give out a lot of greenhouse gas (温室气体).
④There are more and more people who support being vegetarians. For example, schools across many parts of the world hold “Meat Free Mondays” to show how easy it is to eat less meat. Some people go one step further and eat vegetables only all the time. Just being a vegetarian for one day a week or just eating less meat can go a long way.
1. What are the reasons for people becoming vegetarians?①It helps protect the environment.
②It can keep people fit and healthy.
③It can make people feed more animals.
④Some people believe killing animals is wrong.
| A．①②③ | B．②③④ | C．①②④ |

A． | B． | C． |
10 . Do you often eat candies and desserts? Are you crazy about cola and milk tea? Do you know these snacks and drinks have a lot of sugar? Eating too much sugar causes many health problems, even leads to high blood sugar level, which could bring us diabetes (糖尿病), heart disease, liver disease or even depression.
Besides sweet food and drinks, there is hidden sugar in everyday food. For example, there is much sugar in bread and yogurt. It is hard for us to avoid sugar, but do we have to stay away from it completely? That’s impossible and unnecessary. After all, sugar is one of the energy sources that we need. What we must do is to control the sugar intake.
Here are some possible ways to help you. First, get to know how much sugar we need a day. World Health Organization (WHO) suggests adults and children should limit sugar intake to 25 grams or less every day. Then, check the ingredients list and buy food with the lowest sugar. What’s more, pay attention to our blood sugar level. Jessie Inchauspe, a French bestselling writer, shares some of her ideas to balance our blood sugar level.
· Eat foods in the right order.
Eat your vegetables first, followed by eggs and meat, then rice or bread.
· Eat vegetables before each meal.
It is better to have hot or cold green salad.
· Reach for vinegar (醋) before you eat.
This is having a teaspoon of vinegar in a glass of water before meals.
· Move after you eat, within 70 minutes.
It could be going for a 10-minute walk, doing a short workout, or doing some chores.
By now, you’ve already known how to improve sugar intake patterns. However, what we do is more important than what we say. Small steps can add up. Let’s begin to make changes on our own.
1. Eating too much sugar causes many health problems EXCEPT ________.| A．worries | B．diabetes | C．depression | D．heart disease |
