1 . Pollution is a disaster for the soil. When chemicals go into the ground, they slowly reduce the fertility of the soil and make it unsuitable for farming. They may also change the structure of the     soil , which gets more easily destroyed by water and air.

For ordinary consumers, the influence of soil pollution can be felt most strongly in the supermarket. Exposure( 暴 露 ) to soil pollution can pollute foods grown in the field, harming people’s health.

One example of this is the “ poisonous rice event” that surfaced in 2013. Some rice from Hunan province was found to contain higher levels of cadmium(镉), a kind of metal likely to cause cancer, because Hunan has some of the worst soil pollution in China, according to CBC News. All the samples collected from this area were heavily polluted by cadmium. Sometimes, the cadmium level is 20 times higher than the national standard.

According to scientists, high levels of cadmium have been linked to organ( 器官) failure,weakening of bones and cancer. “ Cadmium is likely to store up in the kidney and liver,” Chen Nengchang, a scholar at the Guangdong Institute of Eco-environment and Soil Sciences, told The New York Times. “ When the amount reaches a certain point, it will cause a serious health risk for the organs.”

Unfortunately, fixing the problem was not as simple as destroying a few piles of rice. Since the outer covering of rice are often used to feed farm animals, the meat we eat and the milk we drink may both be at risk.

Luckily both the government and Chinese consumers have becomes more and more aware of this kind of pollutions, and aim to fight the situation with combined effort. There are many things we, as individual, can do to help. Eating organic foods are one of them.

Organic food is not only better for our health but also for our environment, especially the soil. To grow organic food, farmers stop using all artificial chemicals------including fertilizers, and pesticides. This production method does not cause any risk of soil pollution, unlike traditional   farming, which uses tons of artificial chemicals. By consuming organic foods, we support healthier soil.

A 14-year-old Girl Built an App to Help Alzheimer’s patients (老年痴呆症患者）

For many teenagers, their lives typically might circle around schoolwork and spending time with friends. Not so for Emma Yang. Though the Hong Kong-born girl is only 14, she     1    (create) her own mobile app for Alzheimer’s patients already.

The Timeless app, which Yang spent two years     2    (develop), comes with several important features. It is an artificial intelligence-powered facial recognition system in the app     3    helps Alzheimer’s patients identify people in photos and remember who they are. It also allows photos     4    (group) by individuals as well as provides a picture-based phone book, which enables a user to tap on photos to call or text a person.

The inspiration to develop an app that would help Alzheimer’s patients connect with their loved ones came to Yang at the age of 12, when her grandmother started forgetting things like     5    she lived and Yang's birthday.

“I wanted to create something to help people like my grandmother stay     6    (connect) with her family,” Yang said. It was a task she was well-prepared to undertake,     7    venture capitalists didn’t take her work seriously. Yang started a crowd finding campaign in March last year to support her 37/we/es^ app project. That effort raised more than $10,000.

At present Yang works with an international team that includes a designer in California and a developer in Cologne, Germany. The chief technology officer of Kairos, the AI company     8     technology is used in the Timeless app, is now Yang’s adviser.

Yang urged other young, ambitious people to believe in     9    because the teenagers of today will be tomorrow’s leaders. “Technology has been able to make kids put their ideas into action，’’ she said “    10     yon get out there and put yourself out there, tell people about your idea and find out who’s on board and can get behind it，you’ll eventually find that team of people.”

Traffic science is one of those     1    which seems permanently poised on the verge of a breakthrough. Professional journals regularly publish promising research, and the    2     trumpets their importance. However, it turns out that traffic is a deceptively complicated problem. It     3     molecular physics, in fact, because it's a system of individual particles     4     in complex ways. Except, with traffic, the particles have minds of their own.

There are two kinds of traffic flow. In uncongested stable flows, cars can move at or near the speed limit, and the "unstable regime," what laypeople (外行) call a stop-and-go traffic. What scientists have figured out over the past decade or so is when and why traffic    5     between the two.

“We see in our models that traffic becomes unstable when the number of cars (passing a specific spot) per lane per hour reaches between 2,000 and 2,500. At that nominal capacity level, traffic is very likely to become unstable,” says Hani Mahmassani, a traffic scientist at Northwestern University in Chicago.

Consider a    6     case. A slow-moving car shifts into the left lane to pass an even slower-moving car. The car    7     behind the lane-changer has to decelerate    8    - not just to the speed of the car in front of him, but slow enough to create a safe driving distance between them.

The next car back has to slow down even more, again to give itself a    9    . This slowdown ripples back through the lane and eventually spreads into the other lanes as nearby drivers notice the sea of brake lights and reflexively slow down. Traffic researchers    10    to this as a shock wave, and it can travel back for miles.
