For more than six million American children, coming home after school means coming home to an empty house. Some deal with the situation by watching TV. Some may hide. But all of them have something in common. They spend part of each day alone. They are called latchkey (门锁钥匙）children. They're children who look after themselves while their parents work. And their bad condition has become a subject of concern.
Lynette Long was once the headmaster of an elementary school. She said，“We had a school rule against wearing jewelry. A lot of kids had chains around their necks with keys attached. I was constantly telling them to put them inside shirts. There were so many keys. It never came to my mind what they meant. ” Slowly, she learned they were house keys.
She and her husband began talking to the children who had them. They learned of the effect working couples and single parents were having on their children. Fear is the biggest problem faced by children at home alone. One in each three latchkey children the Longs talked to reported being scared. Many had nightmares and were worried about their own safety.
The most common way latchkey children deal with their fears is by hiding. It might be in a shower stall, under a bed in a closet. The second is TV. They'll often play it at high volume. It's hard to get statistics (统计数字）on latchkey children, the Longs learned. Most parents are slow to admit they leave their children alone. The main idea about "latchkey children” is that they_________

One of the most fascinating things about television is the size of the audience. A novel can be on the “bestseller” lists with a sale of up to 100,000 copies, but a popular TV show might have 70 million TV viewers. TV can make anything or anyone well-known overnight.
This is the principle behind “quiz” or “game” shows, which put ordinary people on TV to play a game for prizes and money. A quiz show can make anyone a star, and it can give away thousands of dollars. Charles Van Doren, an English instructor, became rich and famous after winning money on several shows. He even had a career as a television personality. But one of the losers proved that Charles Van Doren was cheating. It turned out that the show’s producers, who were pulling the strings, gave the answers to the most popular competitors in advance. Why? Because if the audience didn’t like the person who won the game, they turned the show off. The result of this cheating was a huge scandal(丑闻). Based on the show off, a movie titled “Quiz Show” is on 40 years later.
Charles Van Doren is no longer involved with TV. But game shows are still here, though they aren’t taken seriously. In fact, some of them try to be as ridiculous as possible. There are shows that send strangers on vacation trips together, or that try to cause newly-married couples to fight on TV, or that punish losers by humiliating(羞辱) them. The entertainment now is to see what people will do just to be on TV. People still win money, but the real prize is to be in front of an audience of millions.What is the most important thing as to television?

While I was in 9th grade, I built a circuit (电路装置) for the traffic system of our city. After getting the first prize, I got this valuable advice from my father: “Do whatever interests you, and don’t let the work challenge you, make sure you are challenging that work.”
I have always preferred the projects which are challenging and related to real life problems. I clearly remember building a shipping program several years ago. I divided the whole project into several small sections. When I understood it clearly, I used my brainstorming skill on it, and gave some basic ideas. Then I asked my professor for help before jumping into coding (编码). At first, I did not know how to ask questions correctly and always asked the question “How do I do it?” As I kept working and discussed with my professor, I became more comfortable and those “how” questions soon turned into “what if I do this and that” types of questions.
It took me four days to write the code. The desire to solve the problem kept me sleepless all nights brainstorming in even greater details. Every time I saw my program running smoothly, I exploded with joy. I still remember the last day of my work. I was getting some problem and didn’t know what to do. At that moment, a man came in to clean. He had headphones, and he was dancing while cleaning the room. Seeing this, I burst out laughing. That moment calmed me. I regained energy and interest and started to work again, and soon I fixed the problem.
My success in the project proved that breaking up a large problem into small parts could help find a possible solution. Discussing the problem with others was also very beneficial. Now I have gained the confidence to attempt any kind of project. According to the passage, the writer was interested in ______.
| A．developing traffic systems | B．doing challenging projects |

We produce 500 billion of plastic bags in a year worldwide and they are thrown away pollu
ting oceans, killing wildlife and getting dumped in landfills where they take up to 1,000 years to decompose. Researchers have been unsuccessfully looking for a solution.
The 16-year-old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute, has-discovered a way to make plastic bags degrade(降解) in as few as 3 months, a finding that won him first prize at the Canada Wide Science Fair, a ＄10,000 prize, a ＄20,000 scholarship, and a chance to revolutionize a major environmental issue.
Burd’s strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.
With this goal in mind, he grounded plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks.
The inputs are cheap, maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.
“Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself.” Said Daniel Burd.Daniel Burd won first prize at the Canada Wide Science Fair because .
