Is Fresh Air Really Good for You?

We all grew up hearing people tell us to “go out and get some fresh air.” 36． According to recent studies, the answer is a big YES, if the air quality in your camping area is good.

37． If the air you’re breathing is clean—which it would be if you’re away from the smog of cities—then the air is filled with life-giving, energizing oxygen. If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles(肌肉) and your brain.

Recently, people have begun studying the connection between the natural world and healing(治愈). 38． In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood(情绪).Greenery is good for us. Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see buildings or sky instead. 39． It gives us a great feeling of peace.

40．While the sun’s rays can age and harm our skin, they also give us beneficial Vitamin D  . To make sure you get enough Vitamin D—but still protect your skin—put on sunscreen right as you head outside. It takes sunscreen about fifteen minutes to start working, and that’s plenty of time for your skin to absorb a day’s worth of Vitamin D  .

A．Fresh air cleans our lungs.

B．So what are you waiting for?

C．Being in nature refreshes us.

D．Another side benefit of getting fresh air is sunlight.

E.But is fresh air really as good for you as your mother always said?

F.Just as importantly, we tend to associate air with health care.

G.All across the country, recovery centers have begun building Healing Gardens.

  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.

d. US company Gilead Sciences developed drugs to treat Ebola.

A．ab                         B．ac                          C．bc                          D．cd

53．What if Chinese scientists kept the information to themselves?

A．The research process could be delayed and the chance of defeating the virus would be lessened.

B．They could let the world download the information for free.

C．The world could develop the vaccine more quicker than now.

D．Chinse scientists could work to help the world.

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.

Few people I know seem to have much desire or time to cook. Making Chinese 36．(dish) is seen as especially troublesome. 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. I still remember 39． (visit) a friend who’d lived here for five years and I 40．(shock) when I learnt she hadn’t cooked once in all that time.

While regularly eating out seems to 41．(become) common for many young people in recent years, it’s not without a cost. The obvious one is money; eating out once or twice a week may be 42．(afford) but doing this most days adds up. There could be an even 43． (high) cost on your health. Researchers have found that there is a direct link between the increase in food eaten outside the home and the rise in 44．(weigh) problems.

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.
