4 . Should schools report a student’s health to parents?
As if grades weren’t enough to worry about, some students now have weight on their minds too. The number of overweight children in the United States has more than doubled in the past 20 years, according to the U.S. Centers for Disease Control and Prevention.
As a result, schools in several states, from California to Pennsylvania, have started sending home "BMI report cards". Those schools send home a report of a student’s body mass index (BMI). BMI is a calculation of weight and height that tells whether a person is overweight for his or her age.
Some lawmakers say BMI reports warn parents of their children s health problem help fight against obesity. In 2003, former Arkansas Governor. Mike Huckabee helped launch the first program to report students’ BMI.
| A．Should schools send home BMI reports? |
| B．Obesity rates in that state have since stopped increasing. |
| C．Since then children with heart disease have received the reports. |
| D．Not everyone thinks that reporting students’ BMI is a good idea. |
| E．Schools agree that more activities are required for students to control weight. |
| F．Being obese, or severely overweight, can lead to health problems later in life. |
| G．Some people argue that schools that label students overweight are acting unfairly. |
Laura Stevens was nine years old. But every single time her mother and her father went out，they insisted that Mrs. Thomas stay with her. Laura didn't like Mrs. Thomas. She wouldn't let her stay up late to watch television, she wouldn't let her eat more than three cookies, and she even made Laura play games with her! "I'm not a baby”. Laura pleaded with her parents. "I'm nine years old. I don't need a baby-sitter. And if you make me have one, I'm going to go to my room and stay there forever”.
“Laura, "scolded her mother, "you're acting just like a baby. That's why you need a baby-sitter.” Laura sighed. But if she didn't complain, she wondered, would she still have to have a sitter? But no matter what Laura did, every time her parents went out they insisted Mrs. Thomas stay with her. And every time Mrs. Thomas stayed with her, she was very nice to Laura, but made her obey stupid rules. But someday, Laura knew, someday she would be big enough to stay by herself, or at least have a baby-sitter who wasn't so bossy.
One night, Laura's parents had a big surprise for her. Mrs. Thomas had gone to visit her sister in another city. Her parents had hired a brand-new Robo-Sitter! When the Robo-Sitter was delivered，Laura was amazed to discover that she looked just like a real person and even sounded like a real person. Her father programmed the Robo-Sitter to make dinner for Laura, give her three cookies, help her with her homework, and so on. And then he programmed the Robo-Sitter to clean the whole house. When he pressed "Enter" the Robo-Sitter's eyes opened brightly and a big smile appeared on her face.
When Laura's parents left the house, Laura reprogrammed the Robo-Sitter! The Robo-Sitter whizzed around the whole house, cleaning it from top to bottom in less than a minute. Then she raced into the kitchen and returned carrying three whole boxes of cookies, which she handed to Laura. Then she did all of Laura’s homework in nine seconds. Then she put Laura's favorite movie in the VCR and got out of the way. Laura sat down in front of the TV set with her box of cookies and pressed the "Off" button. And just like that, the Robo-Sitter went to sleep. Laura ate her cookies and watched her movie. But after a little while, her stomach started hurting and she wanted someone to talk to. She turned on the Robo-Sitter, who immediately cleaned the whole house all over again, brought Laura three more boxes of cookies, and did Laura's homework for a second time. Laura tried to reprogram the robo-Sitter, but was only able to make her do the same things faster and faster. Laura had no choice and finally turned off the Robo-Sitter.

The house was very quiet.

6 . If you really want to go green, here’s good news: eating green foods is good for you. The very foods with a high carbon dioxide cost — dairy products, processed snacks — also tend to be filled with fat and calories. A green diet would be mostly vegetables and fruits, wholegrains, fish and lean meats like chicken — a diet that’s eco- and waistline-friendly. Eating green foods can be healthier and beneficial to the climate.
It may be hard to believe that a meal at McDonalds produces more carbon dioxide than that your trip to a faraway place produces. More than 37% of the world’s land is used for agriculture, much of which was once forested. Deforestation (砍伐森林) is a major source of carbon dioxide. The fertilizer (肥料) and machinery needed on a modern farm also have a large carbon footprint, as does the network of ships and trucks that brings the food from the farm to your plate.
The most efficient way to reduce the carbon footprint of your menu is to eat less meat, especially beef. Raising cattle takes a lot more energy than growing the equivalent (相等的) amount of grains, fruits or vegetables. What’s more, the majority of cattle in the U.S. are fed on grains and the fertilizer used to grow grains creates separate environmental problems.
Focus on eating food lower on the food chain, with more plants and fruits and less meat and fewer dairy products. It’s simple. We can change today what goes into our bodies for the health of our planet and ourselves.

7 . We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(装置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.
As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2007 window.
So what's the solution（解决方案）? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.
