Some schools are worried that children might become fat or eat unhealthy food, so they have banned cupcakes altogether. What do kids do? Birthday kids can donate a book. The headmaster of their school will then read it to their class. The headmaster also hands out birthday certificates , special pencils, and makes sure the kids' names are read out in the school's morning news. Parents can send stickers , pencils and other things to students. None of the things can be food. If a child donates jump ropes or other sports equipment, that child may get his or her name on a certificate. It will then be displayed at school. Archisha really misses cupcakes, especially those her mother used to make for her kindergarten class, but her school's way is fun, too. "I like both ways," she said. The headmaster says it's important that the school should be not only teaching, but offering healthy choices to kids. "There is a better life without cupcakes. If you eat a cupcake, then it's gone in two seconds, but a book lasts a lifetime. The sports equipment lasts, and the kids can use it day after day." Question: What do birthday kids do? Options: A: They can borrow a book. B: They get birthday certificates. C: They get special pens. D: They eat birthday cakes.

Question: Read the article and select the best answer. Article: Amos Dudley, a 24-year-old boy who studies digital design at New Jersey University of Technology, felt ashamed about his teeth. But being a student, Dudley didn't have the money to get braces . So, he decided to 3-D print his own and marked down the DIY project in a recent blog post. His braces totaled less than $60, and after wearing them for 16 weeks, his teeth are also getting straighter. Months ago, he mentioned on his blog that he avoided smiling for a while because he was unhappy with his teeth. However, clear braces can get pricey, costing up to $8,000. But after studying some images of these expensive clear braces, something comes up on him--they looked like that one which can come from a 3-D printer. So he decided to hit up his school's 3-D printing equipment and scanned and printed models of his teeth. He then made non-harmful plastic molds around them to make 12 sets of braces. Dudley, who does not recommend attempting any of this at home said that he didn't ask a dentist for his project. But the student did get information from journal articles and textbooks. And though this was a perfectly friendly choice to buy braces. He didn't accept the project just to save money--he was also up for the challenge. "When I realized that I could do something that was a little bit special, while proving my skills as a designer and a maker, and fixing something that was making me self-conscious for actually free, I felt it was more than worth the risk." he said. Question: Why did Dudley choose a 3-D printer braces over-buying them? Options: A: He didn't have enough money. B: He felt ashamed about his teeth. C: He studies digital design at school. D: He wanted to be a famous person.

They are just the ordinary ones who do the everyday things. They work without the recognition the famous people get. They are the Olympic volunteers. These people aren't the great stars of sport. They just want to do their part for the Olympics by smiling and helping the Games go smoothly.The stars of the Games are like brightly colored sailboats on the sea, racing through the waves. How lovely to watch them! But the volunteers are the wind, which nobody sees. Without the wind the sailboats would not be able to move and no one would want to watch them. The volunteers breathe the wind of life into the athletes. The volunteers may never win medals, but they always do their best to encourage the _ , whether the athletes win or lose.Some might think what the volunteers do is boring, hardly worth mentioning . But in my eyes, they are as important as the champions and the stars. They are just as much heroes, despite not appearing in newspapers or on TV. I truly admire them and I will always cheer for them. They are my Olympic heroes. Question: What does the writer think of the volunteers' work? Options: A: boring B: important C: interesting D: excellent

Read the article and select the best answer. Article: The question whether there is life on Mars has made the public think a lot for more than a century. The closest look showed Mars to be a dusty, cold world, covered by air too thin to breathe. A British spaceship and Europe's Mars spaceship plan to land on Mars or enter orbit around it. One of the NASA's spaceships is expected to land on January 3, the other is going to land on the opposite side of Mars on January 24. Since 1960, over twenty spaceships sent to Mars have failed. Most have been lost on flying up or landing because those are the most difficult times of any flights. Scientists wanted to find out whether there was water in Mars. In October, a team of scientists reported that Mars had been a dry wasteland. But weeks later, a second team reported differently that they had found some marks showed clearly that they were made by the rivers. Such marks told us that Mars was a warmer place billions of years ago -- just as life first appeared here on Earth. Scientists at once raise a question: if what they said is true, what happened on Mars? Then what about the earth? Question: A team of scientists reported that there might be _ in Mars. Options: A: nothing but air B: nothing C: water billions of years ago D: thick air and lakes
