Health is     1     most important thing in the world. Nothing is more important than health. If one takes away our money, houses, cars, or even our clothes, we can still survive.     2     if our health is taken away, it is certain that we surely die. That is why we always try to eat in a     3     (health) way and exercise often.

How can we keep healthy? In order to eat healthily, I usually avoid     4     (eat) food high in fat, like French fries or cookies,     5     are junk foods. I eat lots of vegetables and fresh fruit. Besides, I only eat a little meat.

On the     6     hand, doing exercise is very important. Taking exercise every day     7     (help) us build a strong body. Regular exercise is an important part of keeping me healthy.

What’s more, I think friends are important part of one’s health. I always feel better when I am with friends than alone. When I am with friends I always laugh. Laughing is also an important part of health. It is good     8     (stay) with my friends. By eating properly and exercising     9     (regular), I can keep my body at a proper weight. By spending time with my friends, I can keep my mind as well as my body happy. These things sound easy to do, but not many people can manage     10     (they). I think a strong will is necessary if we want to keep fit.

As a nature photographer, I enjoy     1     (work) outside in the wild. One of the best things about this job is that you can see animals in their     2     (nature) environments.

My favorite place to take     3     (photo) is Yellowstone National Park. As the world’s first national park, it is     4     (probable) best known for its bears. Although the bears have a     5     (weigh) of up to 300 kilograms, they are good runners and excellent swimmers.

Last spring in Yellowstone, I followed a path     6     took me through a dark forest. When I finally stepped out of the trees, the view was amazing. While I     7     (concentrate) on photographing this scene, I suddenly had a feeling that I was being watched. Slowly, and with the camera still held to my eye, I turned and was frightened. Only metres away from me was a bear. With water falling off     8     (it) thick, brown hair, the bear stared back     9     me. Time stood still as the bear and I both waited     10     (see) who would move first. My legs started shaking. Somehow, I forced my finger to press the button. Luckily, a second later, the bear turned and ran back into the forest.

In order to make young people realize the     1     (important) of the Social Media Detox, we held     2     activity. Over 100 students had been persuaded     3     (stop) using social media for seven days, most of whom     4     (be) excited and nervous. It took Anna two days to be aware of the seriousness of     5     (check) phone. Doing the detox not only     6     (make)Devon realize the value of     7     (really) contact but also motivated Cindy to visit a different friend every day. An hour’s sport each day let George become healthier and healthier. It is a pity that Max threw in the towel     8     the first day. In a word, the Social Media Detox is successful,     9     helps teenagers step away from social media and communicate with each other     10     (well).

A casual walk along the Beijing Central Axis,     1     (connect) the Drum Tower, the bustling Nanluoguxiang Lane, the Jingshan Park and the majestic Forbidden City—this was Zhao Xianghan’s maiden city-walking journey in the spring of 2022.

Since then, the 21-year-old student from the Beijing Foreign Studies University     2     (remain) a city-walk enthusiast, believing it to be the best way to rediscover a city.

“I visited Beijing before the start of my college life here, and it was a typical package tour during     3     going to scenic spots and taking photos was a big thing. The crowded tourist attractions gave me the     4     (impress) that Beijing was a noisy place,” said Zhao.

“Yet now a city-walk allows me     5     (see) a whole different side of Beijing, which is full of serenity,” Zhao added.

With the increasing variety of travel options,     6     (tradition) group tours can no longer satisfy people who are looking for a more personalized and different travel experience     7     hoping to find every part of the city in a more immersive way, according to a blog posted on social media platform WeChat that has gained more than 100, 000 views.

    8     (compare) with tightly scheduled itineraries(行程) and picture-taking tours, city-walking focuses     9     free, casual and spontaneous experiences.

“City-walk is all about doing whatever you want in your own exploration of a city, and it is     10     (actual) a kind of slow-paced and low-carbon lifestyle that I relate to so much,” said Zhao.

Recent studies have shown the benefit — even necessity — of     1     (spend) time outdoors, both for kids     2     adults. Some argue that it can be any outdoor environment. Some say it has to be a “green” environment — one with trees and leaves. Most of the studies agree that kids who play outside are     3     (happy) and less anxious ( 焦虑的) than kids who spend more time indoors. While it’s unclear how     4     (exact) the mood improvements happen, there are a few things we do know about why nature is good     5     kids’ minds.

There are various ways     6     (explore) outdoor environments, from the backyard to the park, and letting a child choose how he treats nature     7     (mean) he has the ability to control his own actions. This style of play also allows kids to interact ( 互动) meaningfully with their environments. They can think more freely, design their own activities, and approach the world in     8     (interest) ways.

Most ways of interacting with nature include more exercise than sitting on the sofa. Kids don’t have to join the local soccer team or ride a bike through the park — even a walk will get their blood pumping ( 流通). Not only is exercise beneficial to kids’ bodies, but it seems to make     9     (they) more focused, which is especially beneficial for kids with ADHD ( 多动症).

So while screen time is the easier, more popular choice,     10     is important to set enough time for outdoor play.

Home to the headwaters of the Yangtze, Yellow, and Lancang rivers, the Sanjiangyuan area on the Qinghai-Tibet Plateau (青藏高原)     1    (know)as “China’s water tower.” It is    2    unique plateau wetland ecosystem and serves as an important ecological defense for the country.

Decades ago, serious     3     (environment) degradation (恶化) in Sanjiangyuan,     4    was caused by climate change and human activities, resulted in a large number of lakes drying out and wildlife numbers falling     5     (sharp). Great efforts have been made to turn the park     6    a symbol of the progress of China’s ecological civilization.Over the past years, the environment of the Qinghai-Tibet Plateau     7     (experience) great changes. Water conservation in the area has risen by 11 percent this year,     8     (compare) with 10 years ago. Local people enjoy the gifts given by nature, and the establishment of the national park has enabled them to become its protectors and benefit from it. Some work as tour guides, assisting     9     (visitor) from home and abroad.

Today, as people walk on the vast land of Sanjiangyuan,     10     (look) at the mountains, glaciers, and lakes, and catching sight of wild animals and birds, they cannot help but be impressed by the vastness and beauty of nature.
