4 . The connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.

The engineers at the Massachusetts Institute of Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when they’re short of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.

One of his latest projects has been to make plants glow(发光)in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn trees into self-powered street lamps.

In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.

Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)-such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission(传输).Glowing plants could reduce this distance and therefore help save energy.

5 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

China has become the first country to land a spacecraft on the far side of the moon. The unmanned Chang’e-4 probe (探测器) - the name was inspired by an ancient Chinese moon goddess     1     (touch) down last week in the South Pole-Aitken basin. Landing on the moon’s far side is     2     (extreme) challenging. Because the moon’s body blocks direct radio communication with a probe, China first had to put a satellite in orbit above the moon in a spot     3     it could send signals to the spacecraft and to Earth. The far side of the moon is of particular     4     (interesting) to scientists because it has a lot of deep craters (环形山)， more so     5     the familiar near side. Chinese researchers hope to use the instruments onboard Chang’e-4     6     (find) and study areas of the South Pole-Aitken basin. ＂This really excites scientists,＂ Carle Pieters, a scientist at Brown University, says, ＂because it     7     (mean) we have the chance to obtain information about how the moon     8     (construct)＂ Data about the moon’s composition, such as how     9     ice and other treasures it contains, could help China decide whether     10     (it) plans for a future lunar (月球的) base are practical.

6 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

7 . A Few Tips for Self-Acceptance

We all want it… to accept and love ourselves. But at times it seems too difficult and too far out of reach.     1     Here’s a handful of ways that will set you in the right direction.

●    2     Do not follow the people who make you feel not-good-enough. Why do you follow them? Are you hoping that eventually you will feel empowered because your life is better than theirs? Know that your life is your own;you are the only you in this world.

●Forgive yourself for mistakes that you have made. We are often ashamed of our shortcomings, our mistakes and our failures.     3     You will make mistakes, time and time again. Rather than getting caught up in how you could have done better, why not offer yourself a compassionate (有同情心) response? ＂That didn’t go as planned. But, I tried my best.＂

●Recognize all of your strengths. Write them down in a journal. Begin to train your brain to look at strength before weakness. List all of your accomplishments and achievements. You have a job, earned your degree, and you got out of bed today.     4    

●Now that you’ve listed your strengths, list your imperfections. Turn the page in your journal. Put into words why you feel unworthy, why you don’t feel good enough. Now, read these words back to yourself.     5     Turn to a page in your journal to your list of strengths and achievements. See how awesome you are?

A．Feeling upset again?

B．Where do you start?

C．Nothing is too small to celebrate.

D．Remember, you are only human.

E．Set an intention for self-acceptance.

F．Stop comparing yourself with others.

G．When does the comparison game start?

Maybe it’s an unreasonable fear. But the ____________ is that I shouldn’t lie to my kids. I should just ____________ repeatedly having to say, ＂No. We can’t go outside now.＂ Then when they come to other doors in life, whether they are real or metopherical, they won’t ____________ to open them and walk through.

10 . Is Fresh Air Really Good for You?

We all grew up hearing people tell us to “go out and get some fresh air.”     1     According to recent studies, the answer is a big YES, if the air quality in your camping area is good.

    2     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).     3     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.     4     It gives us a great feeling of peace.

    5    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.
