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.

On Children's Day last year, our city held an interested activity, in which children and their parents play the rich and the poor. In the dinner, the rich could have more delicious food, but the poor could only have breads with porridge(粥).Parents both hoped to have the dinner for the poor with the children. They hoped that their children could be taught the lesson from the dinner. Now many people in the world don't have enough food and clothes.
Every day only one half the world could enjoy enough food. The activity was holding to make the families understand the differences from the poor and the rich and also make the parents know that too much material life won't always do good to the children.
