Ques:The year of 2014 saw smart people always busy inventing useful things, which have hepled to make the world better, smarter and a little for fun. Now, let's take a look at some of the inventions. Super banana Australian biogeneticist  James Dale visited Uganda, a poor African country, in the early 2000s, where he found that 15-30 percent of children under 5 were at risk of going blind because they did not get enough Vitamin A. Dale also learned that people there love bananas. They eat three to 11 bananas a day. So he came up with the idea to plant bananas containing added nutrition in order to improve Ugandans' health. With the help of Bill Gates' foundation, Dale developed the "super banana". He added a gene to the fruit, making it rich in Vitamin A. Coaching basketball Basketball is popular worldwide, partly because you only need a hoop  and a ball to play the game. But this simple game has experienced a technology makeover this year with the development of a smart-sensor basketball. The ball, called the 94Fifty Basketball, has nine sensors inside. They can tell you anything from how fast you are going to how accurate your shot angles are. With a Bluetooth chip inside, the basketball can connect to your smartphone and tell you in the voice of a coach to "snap your wrist  ", or"go faster", depending on the data. The Hovercraft Thanks to the California-based company Hendo, flying past your friends on a floating board could soon become a reality. The Hovercraft has four small engines. These create a special magnetic field which produce enough force to lift the board off  the ground. At the moment, the hoverboard  can only float an inch off the ground for 15 minutes and must fly over a metal material. It's expensive too, at $10,000 (61,810 yuan), but the company hopes that one day the technology could be used. Wireless electricity Most of us could not bear to live without wireless Internet. We use it every day for everything from our phones to our cars. But one company wants to go a step further, by combining... What do the hovercraft and wireless electricity have in common according to the text?. A) They create magnetic fields to produce power. B) They apply technologies to many things in life. C) They apply technologies which can produce electricity. D) They use wireless technology to improve their products.

Ques:By 2050 there will have been an extra 2.5 billion people on earth. And what will they eat? To solve the problem, we should have to double our food production. We can also develop a diet of algae , insects and meat grown in laboratories. Algae can grow very quickly at sea, in polluted water and in places that would normally kill food crops. They are already eaten widely in Japan and China and they are eaten by almost everything from shrimps to blue whales. They can fix CO2 in the atmosphere and provide fats and sugars. Man-made meat looks like meat, feels like meat and it is meat, although it's never been from a living, breathing animal. Instead, it is grown from cells in big containers. Moreover, studies show that producing man-made meat will use far less water, energy and land. China has developed "green super rice", a series of rice types which produce more grain and have stronger ability to fight against floods, salty water, insects and disease. We used traditional plant breeding techniques to cross-breed more than 250 rice types. Green super rice, which is enough to feed an extra 100 million people, will be planted widely in the coming years. Insects like ants are not on most European menus but at least 1,400 kinds are eaten across Africa, Latin America and Asia. Now, with rising food prices and worldwide land shortages, such insects are getting more and more popular. Not only are many insects rich in protein , low in fat and high in Ca and Fe, but insect farms need little space. And they can grow well on paper, algae and industrial wastes. What can we learn from the passage? A) Green super rice is delicious but high in price. B) In Asia about 100 million people may be faced with food shortages. C) Man-made meat doesn't look like meat but has the same taste as real meat. D) One of the reasons why many people begin to eat insects is their rich food value.

Ques:A dog who chewed off his owner's infected toe while he was passed-out drunk has been called a lifesaver. Jerry Douthett had been out drinking when his dog Kiko bit off a large part if his big toe. His wife, Rosee, rushed him to hospital where tests showed the 48-year-old musician had dangerous high blood-sugar levels. Doctors told him his toe would have had to be cut off anyway. Mr Douthett said he had refused to get medical advice despite his toe being swollen for months. "I was hiding it from people, Rosee included," he said. "It smelled , and I look back now and realize every time we'd visit someone with a dog, their dog would smell all over my foot." The night before Mr Douthett had agreed to see a doctor, he passed out at home after going out drinking. He said, "I woke up and the dog was lying along side by foot. I said, 'Ah, there's blood everywhere.' I ran to the bathroom and started to scream." However, he believes Kiko could sense the disease coming from his big toe. "He's a hero," Mr Douthett said. "It wasn't an aggressive attack. He just ate the infection. He saved my life. He ate it. I mean, he must have eaten it, because we couldn't find it anywhere else in the house. I look down. There's blood all over, and my toe is gone." Before the operation, Mr Douthett asked a nurse, "Is there any chance I can get whatever's left of my toe, so I can give it to Kiko as a treat?" Kiko is still with the family but is under observation by authorities. .What did Mr Douthett think of his dog ? A) It was clever and brave. B) It never attacked healthy people.
