【推荐1】The first thing you should know about Nightfood, a new “sleep-friendly” ice cream，is that it's a genius idea. There are certainly still some doubts whether it actually works. But many people have trouble sleeping, and many people love eating ice cream，and the possibility of cookies-and-cream-flavored Ambien (一种助眠药), even though that's not exactly how the product functions，is going to be irresistible to people with sleep problems everywhere.

“Part of me is like，I’m jealous I’m not part of this marketing programme,” said Raj Dasgupta，assistant professor of clinical medicine specializing in sleep at Keck School of Medicine at the University of Southern California. “They knew exactly how to appeal to customers.”

You could eat Nightfood any time of day without feeling sleepy，but the product is designed for sleep because surveys have shown one of the most common times people tuck into a pint of ice cream is at night, probably while watching Netflix. But can junk food really solve your sleep problems? Probably not, Dasgupta said.

The best way to improve your sleep is to practice good sleep hygiene: have a set bedtime and wake time every day，avoid caffeine and screens late at night, and, uh, do not eat within two hours of your bedtime. But our willpower fails us in the face of a “Russian Doll” binge with a pint of mint chocolate chip.

“They know no one is going to listen to this advice，so，might as well cater to (迎合) them,” Dasgupta said. Sugary snacks “are the no-no foods you don’t want someone to eat before bed. If they’re going to eat it anyway，I’d rather they grab the nutritious one rather than the Twinkie or the cupcake.”

And here's the thing： It actually tastes really good. Unlike other “functional” ice creams that boast of higher protein and lower sugar and fat, Nightfood uses real sugar — no alternative .sweeteners. There is milk and cream in it. It has fewer calories than your typical pint，but you would hardly know it from the texture or taste.

Nightfood is not the only sleep-friendly product on the market. There are also several carbonated sleep drinks, including Som and Neuro Sleep. They might help a bit, but Dasgupta cautions that sleep-promoting foods are not a cure-all.

“You’re not just going to start eating this food and get great sleep. There's other things that go into it, too,” like your overall health, stress level and the amount of time you spend aimlessly scrolling through Twitter in bed.

【推荐2】Many of us eat purely to satisfy our appetite for delicious food. But due to the outbreak of the novel coronavirus pneumonia (NCP), many Chinese people are changing their eating habits.

Due to busy work schedules, ordering simple and quick meals online used to be commonplace (寻常的) for many young people in China. Zhang Xiaoyan, a 30-year-old from Nanjing, Jiangsu province, was one of them. She typically ate in the office and seldom cooked at home on weekdays. Even on weekends, she would prefer takeout food. But amid the NCP outbreak, being trapped at home for an extended (延长的) period has changed her eating habit. Now, she rolls up her sleeves and cooks for herself. “Cooking by myself sometimes is quite time-demanding, but it helps me have a healthy diet,” Zhang told China Daily.

Instead of eating at fast food chains or restaurants, cooking at home has become a nationwide trend. Some even regard sharing food videos on their WeChat Moments at meal times as “a special way to say hello to each other when face-to-face dinner is not possible,” noted China Daily.

Apart from cooking at home, many also eat separately and adopt (采用) the habit of using serving chopsticks and spoons, or gongkuai and gongshao in Chinese.

Influenced by collectivism (集体主义), communal eating habits have been a part of Chinese culture for centuries. For Chinese people, eating one’s own dish would be considered rude during a social gathering. They typically share several dishes laid out in the center of a table and sometimes share utensils (餐具) in the meals to show their respect and closeness.

Though it seems polite, it’s indeed risky. According to World Health Organization, foodborne (食物传播的) diseases are quite common, and saliva (唾液) is one of the most common ways for them to spread. So many cities in China, including Beijing, Shanghai and Guangzhou, have already launched initiatives (倡议) for people to order separate meals.

“Healthy eating habits and maintaining good order have become real issues for us. It’s related to people’s health and safety, and it’s also a personal responsibility during the pandemic (大流行),” noted Guangming Daily. These are habits formed amid the pandemic, but as long as they are good for our health, perhaps we should keep them from now on.

1. How has Zhang Xiaoyan’s eating habit changed?

A．She eats simple and quick meals more often.	B．She cooks meals by herself at home.
C．She now orders more takeout food.	D．She often copies the meals her friends post on WeChat.

2. What do Paragraphs 5-7 mainly talk about?

A．How to change communal eating habits.

B．Why changing communal eating habits helps.

C．The relationship between culture and eating habits.

D．The role collectivism plays in Chinese eating habits.

3. What does Guangming Daily’s quote tell us?

A．Eating habits have a lot to do with our health.

B．Safety always comes first in every situation.

C．People are warned that foodborne diseases are on the rise.

D．It’s difficult for Chinese people to break bad eating habit
