Ques:I cheated on a unit test in math class this morning during second period with Mr Burke Afterward, I was too sick to eat lunch just thinking about it. I came straight home from school, went to my room, and lay on the floor trying to decide whether it would be better to run away from home now or af _ It wasn't even an accident that I cheated. Yesterday Mr.Burke announced there'd be a unit test and anyone who didn't pass would have to come to school on Saturday, most particularly me, since I didn't pass the last unit test I did plan to study just to prove to him that I'm plenty smart - which I am.mostly - except in math. Anyway, I got my desk ready to study on.Just when I was ready to work, Nicho came into my room with our new rabbit and it jumped on my desk and knocked the flashcards all over the floor.What a mess! Nicho and I finally took the rabbit outside but then Philip came to my room and also Marty from next door and before long it was dinner. After dinner my father said I could watch a special on television if I'd done all my homework.Of course I said I had.That was the beginning.I felt terrible telling my father a lie about the homework. It was nine o'clock when I got up to my room and that was too late to study for the unit test so I lay in my bed with the light off and decided what I would do the next day when I was m Mr.Burke's math class not knowing the 8- and 9-times tables. So, you see, the cheating was planned after all. The next day, I'd go into class as usual, acting like things were going just great.I'd sit down next to Stanley Plummer - he is so smart in math it makes you sick - and from time to time, I'd glance over at his paper to copy the answers.Everything was okay except that my stomach was upside down and I wanted to die. The fact is, I couldn't believe what I'd done .in cold blood.I began to wonder about myself.I've never been a wonderful kid that everybody in the world loves.I have a bad temper and I like to have my own way and I argue a lot.Sometimes I can be mean.But most of the... After he was informed of what he had done, the father  _  . A) scolded the author severely B) didn't say anything and left C) called Mr.Burke immediately D) let the author make a call to Mr.Burke

Ques:Every vehicle needs tires, but eventually they wear out. Roads wear out too, and they often need repairing. But new research by a pair of teens suggests the rubber from worn-out tires could lengthen the lifetime of asphalt   pavement. Also roads made with this material might need fewer patches  .   The young researchers presented their findings in May, 2014, as finalists at the International Science and Engineering Fair (ISEF). The 64th annual Intel ISEF shows some of the best high school science projects from around the globe.    Many roads are made with asphalt, which requires much petroleum. But Jordan is a country that has very few oil wells or other sources of petroleum, notes Mohammad Salameh, who is a 10th-grader at the International School in Amman, Jordan.   For Jordan, having to import most of the country's petroleum adds greatly to its cost, the teen notes. The extra expense means that there's less money to build and maintain roads. That has resulted in poorer quality roads. As a result, those roads need to be patched almost constantly.   Therefore, 16-year-old Mohammad and his research partner, 15-year-old classmate Adam Belaid, came up with the idea of adding rubber to asphalt. But that rubber can come from old tires. Even a worn-out tire contains much rubber, which means the material should be plentiful, says Mohammad. Drivers in Jordan replaced 9 million tons of tires between 2006 and 2010, and only 0.3% of that rubber was recycled. That leaves much rubber that could possibly go into road construction.   But first the teens had to show adding rubber to asphalt resulted in better roads. To test their idea, they created several different asphalt-rubber recipes. They also tried out different temperatures at which the mix was heated. And their tests suggested that when the surfacing material includes 8% rubber, it should hold up for 10 to 15 years of traffic instead of the normal 5 years. And their recipe should reduce the need for patching worn areas from once a year, to maybe once every 5~7 years... What made the two teenagers think of carrying out the research? A) Frequent road repairs in Jordan. B) Their interest in recycling old tires. C) The slowdown in the Jordanian economy. D) Their desire to replace petroleum with something.

Ques:Let's face it.No one drinks die t soda  for the taste.People drink diet soda in the hope that it will help them lose weight or at least keep them from gaining it.Yet it seems to have exactly the opposite effect, according to a new study. Researchers from the University of Texas said those who drank two or more diet sodas a day had waist  size increases that were six times greater than those of people who didn't drink diet soda."What we saw was that the more diet sodas a person drank, the more weight they were likely to gain," said Sharon Fowler. The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly l0 years. While the findings are surprising, they also offer some explanations. Nutrition  expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched  from regular to diet soda, they don't lose weight at all."We weren't seeing weight loss necessarily, and that was confusing to us," said Rogers. So why would diet soda cause weight gain? No one knows for sure yet, but it could be that people think they can eat more if they drink diet soda, and so over-compensate  for the missing calories( ). A related study found some sweeteners   raised blood sugar levels in some mice." Data from this and other potential studies suggest that the promotion of diet sodas and artificial  sweeteners may be risky," said study researcher Helen P.Hazuda, professor at the University of Texas's school of medicine. Theymay be free of calories, but not of consequences. People drink diet soda to   _  . A) stay in fashion B) enjoy its taste C) gain more energy D) achieve weight loss
