During the outbreak of novel coronavirus, cities are locked down and borders are closed. Science, on the contrary, is becoming more open. And this “open science” is already making a difference.

Soon after the epidemic started in China, a research team from Fudan University in Shanghai successfully sequenced (测定序列) the DNA of the virus. But they didn’t keep the information to themselves. Instead, they placed the sequences on GenBank, an open-access data platform, so researchers around the world could  download them for free and start studying the virus.

Due to this openness, pharmaceutical ( 制 药 的 ) companies across the globe are now able to work simultaneously (同时地) to develop a vaccine. “There may be room for multiple different vaccines for different purposes and different age groups,” Amesh Adalja, a senior scholar at the Johns Hopkins University Center for Health Security in the US, told Al Jazeera. “The bigger menu we have of vaccines, the more resilient (有适应力的) we’ll be against coronavirus outbreaks in the future.”

Major drug companies around the world are also sharing their study results. Remdesivir, a drug originally developed by US company Gilead Sciences to treat Ebola, is found to be promising in fighting against the novel coronavirus. Currently, two trials of the drug are already underway in China, and the results might be available as soon as April, according to The Verge.

There has been a recent trend in the food service industry toward lower fat content and less salt. This trend, which was started by the medical community(医学界) 26． a method of fighting heart disease, has had some unintended side 27．(effect) such as overweight and heart disease — the very thing the medical community was trying to fight.

Fat and salt are very important parts of a diet. They are required 28．(process) the food that we eat, to recover from injury and for several other bodily functions. When fat and salt 29．(remove) from food, the food tastes as if is missing something. As 30． result, people will eat more food to try to make up for that something missing. Even 31．(bad), the amount of fast food that people eat goes up. Fast food 32．(be) full of fat and salt; by 33．(eat) more fast food people will get more salt and fat than they need in their diet.

Having enough fat and salt in your meals will reduce the urge to snack(吃点心) between meals and will improve the taste of your food. However, be 34．(care) not to go to extremes. Like anything, it is possible to have too much of both, 35． is not good for the health.

Many westerners 37． come to China cook much less than in their own countries once they realize how cheap 38． can be to eat out.

While regularly eating out seems to 41．(become) common for many young people in recent years, it’s not without a cost.

If you are not going to suffer this problem, then I suggest that the next time you go to your mum’s home 45． dinner, get a few cooking tips from her. Cooking food can be fun. You might also begin to notice the effects not only on your health but in your pocket.

    Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.

Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self­conscious (难为情) when they’re in poorly lit places—and so more likely to eat lots of food. If your home doesn’t have enough window light, get more lamps and flood the place with brightness.

Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us feel less hungry. So when it’s time to repaint, go blue.

Don’t forget the clock—or the radio. People who eat slowly tend to consume about 70 fewer calories (卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you’re at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.

Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12­inch plate instead of a 10­inch plate. When we choose a large spoon over a smaller one, total intake (摄入) jumps by 14 percent. And we’ll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.

65．The text is especially helpful for those who care about ____________.

A．their home comforts                                   B．their body shape

C．house buying                                             D．healthy diets

66．A home environment in blue can help people ______________.

A．digest food better                                       B．reduce food intake

C．burn more calories                                     D．regain their appetites

67．What are people advised to do at mealtimes?

A．Eat quickly.                                               B．Play fast music.

C．Use smaller spoons.                                    D．Turn down the lights.

School lunches in Japan

Japan manages a rare achievement for a developed country when it comes to feeding its children — high scores for nutrition but very low obesity rates. One major key? School lunches.

A landmark report by the UN's children agency UNICEF released Tuesday shows Japan topping the charts for childhood health indicators, with low rates of infant mortality and few underweight children.

Experts say there are various factors at work, including a health-conscious society and regularly check-ups for children required by law, but a nationwide school lunch program also plays a key role.

"School lunches with menus that are created by nutritionists are provided to all primary schools and the majority of junior high schools throughout Japan,," Mitsuhiko Hara, a pediatrician and professor at Tokyo Kasei Gakuin University, told AFP.

The lunches are mandatory — no packed lunches allowed — and while they are not free for most, they are heavily subsidized 补助）.Each meal is designed to have around 600-700 calories balanced between carbohydrates, meat or fish and vegetables.

"School lunch is designed to provide nutrition that tends to be lacking in meals at home," Education Ministry official Mayumi Ueda told AFP. "I think it contributes to the nutritional balance necessary for children."

Unlike the cafeteria system operated in some Western countries, Japanese school lunches are usually served in the classroom. Pupils frequently dish out the food to each other and clean up the room afterwards. There is no choice of meal, and no concessions offered for vegetarians, or anyone with religious restrictions.

The lunches are intended not only to feed children, but to teach them. "There's also a daily broadcast at school to explain the nutritional elements contained in the school lunch of the day, and this is a good way to educate kids,” Hara said.

"School lunch is positioned as part of education under the law,'? Ueda said. "It's not just about eating food, but children learn to serve, and clean up on their own?"

The Japanese government studies nutrition and eating habits in Japan annually, and uses the results to shape what goes into the school meals, she added.

And there are other factors at work, Hara acknowledged. "Because many Japanese are health-conscious, they try to eat a variety of food, which is good," he said. "And we're taught to eat seasonal food, which also contributes to good health. Japan is one of the rare countries that pay so much attention to food that is associated with specific seasons," he added.

Hara said another factor in Japan is regularly mandated childcare health checks. Parents of infants receive reminders from the local government, and children are given health checks at school, including measuring height and weight.

Still, even Japan has not escaped entirely the growing trend toward overweight children and childhood obesity, which in Japan, like elsewhere, tends to affect those from less wealthy families.

"Children in poverty are more likely to be overweight because families try to cut costs," Hara said. "As a result, they eat less protein but consume more carbs and sugar, which leads to obesity."

School lunches are all the more important to children in such situations, he said.
