The next day, he got 13 points in another game. Most people think that Yao Ming is a born basketball player. But Yao said, "When you watch it on TV, it looks very easy. But when you are playing in the NBA, it is really not so easy." He said that joining the Houston Rockets was a new start and a new challenge. "I hope that through very hard work I can make everyone happy and help the Rockets win more games," he said.Yao Ming speaks some English. Both he and his teammates can understand each other. They don't think there is a language problem. While Yao Ming faces this new challenge, the people of Houston have shown great interest in him and they hope Yao Ming will bring new energy to the Rockets. The team has started having lessons to learn more about China, and many people who work for the Rockets have learned to speak some Chinese. Question: Yao Ming said that _ . - playing in the NBA was difficult - it was hard to watch NBA games on TV - he was an NBA star - it was boring to play basketball

Read the following article and select the best answer. Article: Cooking food over a smoky fire is found everywhere in the world. It is often difficult to find wood for the fire. People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun. Solar cookers, or ovens, have been used for centuries. A Swiss scientist made the first solar oven in 1767. Today, people are using solar cookers in many countries around the world. People use solar ovens to cook food and to heat drinking water to kill bacteria and other harmful organisms. There are three kinds of solar ovens. The first is a box cooker. It is designed with a special wall that shines or reflects sunlight into the box. Heat gets trapped under a piece of glass or plastic covering the top of the cooker. A box oven is effective for slow cooking of large amounts of food. The second kind of solar oven is a panel cooker. It includes several flat walls, or panels, which directly reflect the sun's light onto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much. In Kenya, for example, panel cookers are being manufactured for just two dollars. The third kind of solar oven is a parabolic cooker. It has rounded walls that aim sunlight directly into the bottom of the oven. Food cooks quickly in parabolic ovens. However, these cookers are hard to make. They must be re-aimed often to follow the sun. Parabolic cookers can also cause burns and eye injuries if they are not used correctly. You can make solar ovens from boxes or heavy paper. They will not catch fire. Paper burns at 232 degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things. To learn more about solar cooking, you can write to Solar Cookers International. The postal address is nineteen-nineteen Twenty-First Street,... Question: Which of the following could be the best title of the passage? - Different Ways of Cooking - The History of the Solar Cookers. - How to Choose Solar Cookers. - Cooking Meals with the Sun for Fuel
(Answer)
Cooking Meals with the Sun for Fuel

Ques: Read the following article and select the best answer. Article: Japanese doctors have used thin sheets of tissue from people's cheeks repair damaged corneas . A team from Osaka University transplanted thin layers of cheek cells onto the eyes of four patients with a rare and painful eye condition,reports BBC online. Patients whose vision had been cloudy could see well afterwards,and the"new corneas"remained clear more than a year after the operation. Doctors can also take cells from a healthy eye and grow them in a dish to produce a new cornea,or they can transplant corneas from donors . But these techniques may not work when both eyes are too badly damaged by accident or disease. The team hope their work may help solve the problem and lead to other types of grow-your-own tissue transplants. The cornea is the clear layer of cells on the surface of the eye. It can be damaged by trauma or by a range of diseases. The team worked with four patients who had a painful condition that causes cloudy corneas and dry eyes. Often the eye can regenerate cornea cells but none of the four patients had this ability. The researchers took a 3 mm-wide square of tissue from inside the mouth(cheeks)and grew it into a thin layer in the lab. They used a special low temperature technique to separate a very thin sheet off each batch. They then laid that onto the patient's eye. The cell layers stuck onto the eye and developed into tissue that looked and acted like a healthy cornea. However,long-term follow-up and experience with a large series of patients is needed to assess the benefits and risks this method. Yet,"it does offer the potential of treating severe eye diseases that are resistant to standard approaches,"said the head of the research,Kohji Nishida. Question: If both eyes are too badly damaged,we can treat them _ . - only by using mouth tissue - by taking cells from a healthy eye and growing them in a dish - by transplant healthy corneas from donors - by none of the mentioned method
Ans: by none of the mentioned method

Read the following article and select the best answer. Article: "Plants were expected to get larger with increased carbon dioxide in atmosphere, but changes in temperature, humidity and nutrient availability seem to trumped the benefits of increased carbon dioxide," said researchers from the National University of Singapore. 45 percent of the species studied now reach smaller adult sizes than they did in the past. The researchers pointed out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for shrinking creatures. "We do not yet know the mechanisms involved, or why some organism are getting smaller while others are unaffected," the researchers said. "Until we understand more, we could be risking negative consequences that we can't yet quantify." The change was big in coldblooded animals. Only two decades of warmer temperatures were enough to make reptiles smaller. An increase of 1 degree centigrade caused nearly a 10 percent increase in metabolism . Greater use of energy resulted in tiny tortoises and little lizards. Fish are smaller now too. Though overfishing has played a part in reducing numbers, experiments show that warmer temperatures also stop fish growth. There is a recent report on warmer temperatures' negative effects on plankton , the base of the marine ecosystem. Warmblooded animals weren't immune from the size change caused by climate change. Many birds are now smaller. Mammals have been miniaturized too. Soay sheep are thinner. Red deer are weaker. And polar bears are smaller, compared with historical records. This is not the first time this has happened in Earth's history. 55 million years ago, a warming event similar to the current climate change caused bees, spiders and ants to shrink by 50 to 75 percent over several thousand years. That event happened over a long time than the current climate change. The speed of modern climate change could mean organisms may not respond or adapt quickly enough, especially those with long generation times. So, it is likely that more negative influences of climate... Question: Which of the following would be the best title for the passage? _ - Why do some species become smaller? - Species become smaller as climate warms - Climate change has many negative effects - How does temperature change in Earth's history?
Species become smaller as climate warms
