【题目】The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid--we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

However, several types of animals can walk on water. One of the most interesting is the common basilisk. Basilicus, a lizard (蜥蜴) native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water's surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we'd need huge feet that we could bring up to our ears in order to create adequate "hitting.

But fortunately there is an alternative: cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a "non-Newtonian" liquid that doesn't behave like normal water. Now, if the surface of the water is hit hard enough, particles(微粒) in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick liquid of cornflour.

Fun though all this may sound, it's still rather messy and better read about in theory than carried out in practice, if you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!

C. It is crazy and cannot become a reality.

【题目】Bill McIntosh and Royce Wedding had been the best friends for 30 years. Now, living alone 12 miles east of the town, Bill earned his living by hunting foxes and rabbits.

"Coming to the football match this afternoon?" Bill McIntosh asked 54-year-old Royce Wedding as they drank beer at the Eureka Hotel. Royce shook his head, "I promised Mom I’d burn off the weeds in one of our fields." “I’ll give you a hand," Bill said.

Driving slowly from the southern edge of the field, they worked their way upwind, leaving a line of burning weeds in their wake. Suddenly the fire was on them. Bill pushed open his door only to find himself thrown through the air, the gasoline tank exploded and the car jumped three feet off the ground. When it crashed back down Royce found himself unable to move. Bill lay where he fell. “Royce!" he cried, struggling to his feet and heading for the car. Pulling open the door, he seized Royce’s arms through the smoke. "I’m stuck," Royce said. “Get yourself away!" The fire bit at Bill’s arms, face and legs, but he said, "I'm not leaving you here.” Now Bill pulled as hard as he could. Suddenly he fell backward. Royce was free and out of the car.

"What's the matter with that dog?" said Vicky Wedding, Royce’s mom. Shocked by noise behind her, she turned to see Bill leaning against the door.

【题目】In New York, Ma Yun witnessed the Alibaba Group opening on the New York stock exchange with the largest initial public offering (IPO,新股发行) in American history. “Alibaba, the world’s largest Internet commerce company makes China equal to the US in the rapidly increasing global competition for technological innovation (创新) and economic transformation commented the South China Morning Post.

Ma told Time magazine that he was “old for the Internet”. He started to slow down and looked around.

【题目】Orcas, or killer whales, are the largest of the dolphins and one of the world’s most powerful animals feeding on meat. They feast on marine mammals such as seals, sea lions, and even whales, employing teeth that can be four inches (ten centimeters) long. They are known to grab seals right off the ice. They also eat fish, squid (鱿鱼), and seabirds.

Though they often frequent cold, coastal waters, orcas can be found from the polar regions to the Equator (赤道).

Killer whales hunt in deadly groups, family groups of up to 40 individuals. There appear to be both permanent and temporary group populations of killer whales. These different groups may hunt different animals and use different techniques to catch them. Permanent groups tend to prefer fish, while temporary groups target marine mammals. All groups use effective, cooperative hunting techniques that some are similar to the behavior of wolf packs.

Whales make a wide variety of communicative sounds, and each group has various noises that its members will recognize even at a distance. They use echolocation (回波定位) to communicate and hunt, making sounds that travel underwater until they meet objects, then reflect back, showing their location, size, and shape.

Killer whales are protective of their young, and other adolescent females often assist the mother in caring for them. Mothers give birth every three to ten years, after a 17-month pregnancy.

Killer whales are immediately recognizable by their special black-and-white coloring and are the intelligent, trainable stars of many aquarium shows. Killer whales have never been widely hunted by humans.

【1】 Killer Whales do not feed on ______.

A. seabirds B. seals C. fishes D. seaweeds
