I paid a visit to Tibet to observe Tibetan antelopes. While     1    (watch) them move slowly across the green grass, I was reminded of their bad old days.

During the 1980s and 1990s, they were shot and killed     2    (illegal) by hunters to make profits. To make things even     3    (bad), their habitats were destroyed to make room for new roads and     4    (railway). As a result, antelopes became     5     endangered species.

In order to change this situation, the Chinese government took some measures. For example, bridges and gates     6    (add) to let the antelopes move easily and keep them safe from cars and trains. Besides, many volunteers watched over the antelopes day and night     7    (prevent) them from being attacked.

These measures prove to be     8    (effect). Its population has recovered and in 2015, the Tibetan antelope was removed     9     the endangered species list. The government, however, intends to continue the protection     10     the threats to the Tibetan antelope have not yet disappeared.

4 . When Simon Cane was in the second grade, he began learning about all the ways humans have an impact on the environment and really took those classroom lessons to heart in a way that set him apart from his schoolmates at his elementary school, P. S. 81, in the Bronx. “He told me we drove too much and made too much pollution,” his dad, Jonathan Cane, told Runner’s World. So Simon convinced his parents to start hanging their clothes to dry, taking the stairs instead of elevators, and other “green” measures.

“For much of kindergarten and first grade I rode my bike to Simon’s school with him on the back,” Jonathan said. “We had a lot of fun being outdoors. We’d stop to give our dog treats and generally enjoyed it.” As Simon got bigger, though, it wasn’t practical for him to ride on his father’s back, but it also didn’t make sense to ride together — both because of safety concerns and because there was no place to put away Simon’s bike. So, most of the time they drove the 1. 5 miles to school.

But in 2019, when Simon was going into third grade, the 8-year-old came up with a new way to help the planet: running the 1. 5 miles to P. S. 81. And Jonathan promised his son he’d join him for as long as he wanted.

“We did a test run one day in August, and decided to give it a go. To be honest, I thought he’d blink (眨眼)after it got really cold or rainy, but he never did,” Jonathan said. He recalled one day when the weather was particularly bad. “It’s really raining out there today,” he told Simon. “And Simon said, ‘Well then we’re going to get wet!’ He took pride in toughing it out, and it became a really fun family routine.”

Since the start, Simon has run with his dad and their black dog, Lola, and has even inspired his mom, Nicole Sin Quee, to join in. They soon became known as “the family that runs to school”.

The 21st century is dominated by more technology-oriented inventions than before. The 20th century     1    (see) man land on the moon. The 21st century will witness man landing on several planets. The first will be Mars, also     2    (call) the Red Planet. As planned by NASA, the mission can be achieved by 2030. That will set a precedent(先例) for explorations by future generations. Furthermore, increased investment in research is likely     3     (lead) to the discovery of a vaccine for AIDS.

Technology is advancing fast. Social media at present acts as one of the leading 64.    4    (source) of news and interaction,     5     has a negative influence on traditional media,     6    (particular) print newspapers. Social media will soon take over the market.

Mobile phones will play a greater role     7     the purchase of goods, as well as the withdrawing and depositing of money. Electronic money will replace paper money. In addition, with declining oil reserves across the world, electric cars will replace petrol cars in a few decades. As     8     result, there will be a major shift in job trends.

Global warming will become an even     9    (big) problem, with sea levels     10    (continue) to rise. Freshwater sources will be polluted. Fresh water will become a major issue. Hence environmental destruction will increase greatly.

6 . The idea of turning recycled plastic bottles into clothing is not new. During the last five years, a large number of clothing companies, businesses and environmental organizations have started turning plastics into fabric to deal with plastic pollution. But there’s a problem with this method. Research now shows that microfibers could be the biggest source of plastic in the sea.

Dr. Mark Browne in Santa Barbara, California, has been studying plastic pollution and microfibers for 10 years now. He explains that every time synthetic clothes go into a washing machine, a large number of plastic fibers fall off. Most washing machines can’t collect these microfibers. So every time the water gets out of a washing machine, microfibers are entering the sewers and finally end up in the sea.

In 2011, Browne wrote a paper stating that a single piece of synthetic(合成的) clothing can produce more than 1, 900 fibers per wash. Browne collected samples from seawater and freshwater sites around the world, and used a special way to examine each sample. He discovered that every single water sample contained microfibers.

This is bad news for a number of reasons. Plastic can cause harm to sea life when eaten. Studies have also shown that plastic can absorb other pollutants.

Based on this evidence, it may seem surprising that companies and organizations have chosen to turn plastic waste into clothing as an environmental “solution.” Even though the science has been around for a while, Browne explains that he's had a difficult time getting companies to listen. When he asked well-known clothing companies to support Benign by Design-his research project that seeks to get clothes that have a bad effect on humans and the environment out of the market, Browne didn’t get a satisfying answer. Only one women’s clothing company, Eileen Fisher, offered Browne funding.

7 . Tips for Green Travel with Kids

Travelling doesn’t mean letting go of all the eco-friendly choices we work so hard to achieve in our daily life. Here are a few tips for green travel with kids.

Booking nonstop flights whenever possible will reduce carbon emissions (碳排放). If the closest local airport doesn’t have nonstop flights to a certain place, check with other local airports to see if nonstop flights are available.     1    

It’s easy when travelling to pull in to fast food restaurants for snacks.     2     My kids love to help plan snacks. I let them create their own snacks for the trip at home.

    3     At the airport, keep your reusable bottles empty until you have passed through the security (机场安检区). Fill them up on the other side of the security checkpoint. Single-use plastic water bottles create unnecessary waste and the plastic can be harmful to your health.

    4     In addition, opening a few windows and turning off the air conditioner (空调) are also good ways to save energy. You should also help your children keep their good, green habits while travelling. Sometimes vacation can mean more than one shower each day-once in the morning and again after getting out of the pool. Pay attention to the number of showers (淋浴) and the length of showers.     5    

8 . A year ago, I decided to create a more environmentally friendly kitchen, focusing on reducing the single-use products such as plastic bags and paper towels. I’m not going to sugarcoat my experience. It takes com mitment and a willingness to change long-held habits. In creating my kitchen, I tried a lot of different alternative products and some plain old com mon sense； the result, however, has been worth the effort. I’m recycling more and relying less on single-use products and I’m saving money too.

I’m not kidding when I say that I used to really love plastic storage bags, so this was, perhaps, the biggest challenge for me. Switching to reusable storage bags is a financial investment, but the cos is reasonable considering that I previously spent at least $ 100 annually on single-use plastic bags and wrap. I willcheck online periodically for recycling updates, where a zero-waste box for kitchen items is offered, from party supplies to mixed-materialfood containers.

I’m a clean freak (怪人) and used to go through an amount of paper towels on a daily basis, butit’s easy enough to take old T-shirts ortowels and cutthem up to use to wipe down surfaces. I’m also a fan of bamboo paper towels, which have the look and feel of traditional paper towels, yet are made from a highly renewable source and also break down in just 45 days. Better yet, they can be reused up to 100 times. As for kitchen sponges (海绵擦), I keep an eye out for those made with natural and recyclable materials.

When purchasing household items online from companies like Amazon or Jet, I will ask to have them shipped in as few boxes as possible or as small a box as possible if a single item is to be sent. I’ll let the company know that they should pay more attention to how It is packaging items for delivery.
