Methods to Help Solve Air Pollution
With the development of the industry, air pollution has become an internationally concerned issue. The governments are taking efficient measures to prevent the situation getting worse. 1. Here are what you can do to help.
1.Leave your cars at home.
Cars, being the greatest source of air pollution, can be left at home this weekend. 2. Other greener options are carpooling, riding a bike or you can also walk if you want a healthier option and if your workplace is not that far away from your home.
2.Volunteer yourself
This is one of the best things you can do. Why? Because it will do you good too.
3. If you have time, there are lots of opportunities out there to pitch in, for instance, planting trees, cleaning a park or simply coming up with ways you can preserve mother Earth.
3.Green-up your home.
This is one of the most common things that people do whenever Earth Day rolls around. That is to switch off their lights. However, this is not something you should do just for a day and for only an hour. 4. In addition, take out all the plugs from plug points even after switching them off.
4.Pledge (保证) to do more every day
You know what the best way to celebrate Earth Day is? Extend your celebrations. That’s right! Do something every day that will improve your surroundings to make the planet a better place to live in. 5. The future of our planet is in your hands.
A.Bathing every day is bad for our health.
B.Voluntary work does good to your body and mind.
C.Travelling via public transport is the better option.
D.Join other like-minded individuals in a common task.

The Himalayan Mountains are home to the highest peak in Mount Everest. Now the first complete study of this remote region shows that is glaciers (冰川) lost billions of tons of ice from 2000 to 2016.
This is the first comprehensive look at what’s happened to glaciers in the Himalaya over a 40-year time, said lead author Joshua Masurer.
“Our study shows a strong signal of glacier ice loss linked to rising temperatures from climate change,” Maurer says. As much as quarter of the regions ice has been lost, he said, “Temperatures in the region have risen one degree, and one degree was indeed enough to produce such a great loss of glacier ice.”
The signal showing Himalayan ice loss linked to rising temperatures would not be so clear if it weren’t for the U. S satellites that photographed the region. Declassified photos from those satellites were turned into 3-D models to show what the glaciers’ elevations and sizes were in the 1970s, Maurer said. Those were then compared to more recent complex NASA satellite photos that shows changing elevations of the ice over time.
The ice and snow in the region are the source for Asia’s great rivers. The study did not include the huge neighbouring ranges of high mountains, but other studies suggest that similar melting is under way there as well.
This melting means flooding and the creation of many glacial lakes. In May 2012, one such flood killed over 60 people in villages near Pokhara, Nepal; it also destroyed houses. Some 800 million people depend in part on rivers from Himalayan glaciers for irrigation, making electricity, and drinking water. The more rapid melting appears to increase the river water during warm seasons, but scientists say that will decrease within decades as the glaciers lose mass.
1.Why did the glaciers in the Himalayan Mountains lose much ice?
A.Many people used the ice to make electricity.
B.The climate change increased the temperature.
C.America used satellite to increase one degree Celsius.
D.The flooding and many glacial lakes took much ice away.
2.How did the scientists get the conclusion?
A.By making an interview.
B.By studying the finding of other scientists.
C.By collecting information by means of satellites.
D.By comparing the data collected by U. S. satellites.
3.What can we infer from Paragraph 5?
A.Only the glaciers in Himalayan Mountains lose ice.
B.Many great rivers run to the Himalayan Mountains.
C.Many Asian regions face the problem of ice loss.
D.The melting of ice is nothing serious.
4.What is the purpose of giving the example in the last paragraph?
A.To show the risk of living near mountains.
B.To show the risky consequence of the ice loss.
C.To ask people to take action to use glaciers.
D.To predict the future of the Himalayan Mountains.
Until now, the oldest evidence of human ancestors outside of Africa was in Dmanisi, Georgia. Here fossils of short people thought to be early Homo erectus date back to about 1.85 million years—just after the species appears in Africa. The oldest evidence of early human activity in China can date back to 1.5 million to 1.7 million years ago, which has suggested that they didn’t leave Africa until 2 million years ago or so—and made it to eastern Asia even later.
Now evidence from the site of Shangchen in the Loess Plateau approximately 1,200 kilometers southwest of Beijing is shaking up that view. More than 2 million years ago, our ancestors were already world travelers, which shows that the ancestors of modern humans left Africa at least 250,000 years earlier than thought. It also supports a minority view that a key human ancestors, Homo erectus, may have originated in Asia, not in Africa.
The same team, led by geologist Zhao Yuzhu of the Guangzhou Institute of Geochemistry at the Chinese Academy of Science found that the stone tools range in age from 1.6 million to 2.1 millions years ago. This indicates humans—the family that includes humans and our ancestors—got out of Africa at least a quarter of a million years earlier than thought, and occupied Shangchen on and off for more than 850,000 years, the team reports today in Nature.
“The dates are convincing,” Zhao Yuezhu says, which suggest humans were already remarkably adaptable to the changeable climate by 2.1 millions ago—even though they had not yet developed the even bigger brains, long legs, or more advanced tools seen in later humans. Although the identity of these early travelers all over the world is unknown, the new dates raise the possibility that H. Erects weren’t the first humans to leave Africa.

American children are still eating lots of fast food---and in spite of restaurants’ promises of healthy options, most kids are sticking with fries over salads. Some infamous chains like McDonald’s and Wendy’s have promised to offer healthier options on their kid’s menus, but they aren’t all sticking it, according to a report from the Rudd Center.
In fact, nearly all parents are buying their kids at least one fast food meal a week. Healthy fruits and vegetables may be all the rage among adults, but busy parents still choose quick meals for themselves and their kids. It doesn’t look like fast food is going away any time soon.
Scientists at the Rudd Center surveyed about 800 parents in 2010, then again in 2013 and 2016. Things have not improved much over the years. Of the vast majority of parents who had made a trip to McDonald’s, Burger King, Wendy’s or Subway in the last week, 74% ordered an unhealthy side or drink. The older the children, the more likely their parents were to choose fries instead of a fruit, or a similar less healthy menu item. And about 35% of parents ordered regular adult menu items for their 2 to 11--year-old children, meaning these kids were often getting larger, less nutritious lunches and dinners.
Even as they introduced options like fruit juices, low-fat milk and yogurt to their menus, some restaurants have also added desserts and other calorie-heavy options to their kids’ menu items. So despite what’s now on offer, kids are getting equally or less nutritious meals, nowadays, which is mostly because fast food restaurants still promote their unhealthy options, and sides like fries are still allowed.
“While most fast-food restaurants do have healthier kids’ meal drinks and sides available, many do little to make parents aware of the healthier options or to encourage parents to choose the healthier options instead of unhealthy ones,” said lead study author Jennifer Harris. “If restaurants are serious about children’s health, they will make the healthiest choice and easiest for parents and the most appealing choice for children.”
1.What do the underlined words “all the rage” in Paragraph 2 mean?
A.popular. B.necessary. C.potential. D.modern.
2.Which of the following can summarize the parents surveyed in the report?
A.Many parents like to eat in McDonald’s.
B.Many parents think eating fast food is healthy.
C.Many parents tend to choose unhealthy food in their daily life.
D.Many parents always ignore the healthy food in their daily life.
3.What should kids avoid eating in fast-food restaurants?
A.Fruits juices. B.Desserts. C.Low-fat milk. D.Yogurt.
4.What does Jennifer Harris advise most fast-food restaurants to do?
A.Offer healthier meals for kids. B.Take children’s health seriously.
C.Be honest about their business. D.Guide parents how to order a healthy meal.
