Question: Read the article and select the best answer. Article: New security camera can "see" through clothes New technology that can " see " through clothing and detect what ' s underneath can now be used to scan crowds, making it a potentially effective tool to prevent terrorist attacks in public places. The Thru Vision T5000 camera picks up Terahertz rays, or T-rays, which are naturally sent out by all objects and can pass through clothes or even walls. The camera can then detect metallic and nonmetallic objects hidden under clothing on still or moving objects without showing any body detail. While similar technology is seen at airports around the world, the T5000 is designed to be used in large, open areas. With a range of 25 meters, the T5000 can screen people in public places, thus avoiding bottle-necks at border crossing or security checkpoints. It also means people can be screened without knowing it. The technology develops from British astronomers' work in studying dying stars. Astronomers use T-ray cameras to see through dust and clouds in space. The company sees uses for its camera at other sites where political or business activities take place. For privacy concerns,Thru Vision Chief Executive Clive Beattie said the image produced by the camera did not show detailed parts of the body. " It's almost a shining light bulb ." Beattie said. "You don' t see the detail that people might be concerned about. " In London' s busy Piccadilly Circus--which is already filled with closed -circuit surveillance cameras-- reaction to the new technology was mixed. Some said the camera was going too far and violating privacy,but others said they are willing to put safety before privacy concerns. " There ' s surveillance everywhere anyway." said one commuter. "I don' t think it' s much of a difference. I don' t care that they can see through me because they can see me anyway." Some experts said the privacy violation of the camera was not worth the benefit. " What we should consider is how much we want to lose our privacy in order to obtain a sort of national security," said David... Question: What can we learn about T5000? Options: A: It can detect metallic and nonmetallic objects underneath. B: It can see through clothing or walls by sending out T-rays. C: It was first used to observe stars by astronomers. D: It is widely used at airports around the world.
Answer: A

Question: Read the article and select the best answer. Article: This is a true story that happened in Japan.In order to _ the house, a Japanese tore open the walls. Japanese houses normally have a hollow space between the wooden walls.

Then he wondered how this lizard survived for 10 years without moving a single step......since its foot was nailed! So he stopped his work and observed the lizard: what has it been doing?what and how has it been eating? Later, he didn't know from where another lizard appeared, with food in its mouch.Ah! He was astonished and touched deeply. The free lizard had been feeding the stuck one for the past 10 years...... Such love, a beautiful love! Such love happened with this tiny creature...

Question: Read the article and select the best answer. Article: Many people consider their pets members of the family and are very sad when they die, but what if you could clone your dog, cat or bird? A scientist in New Orleans, who has proved his ability to clone other animals, is now offering the possibility to pet owners here in Wisconsin. Scientists have not been able to clone dogs, cats or other pets, but if and when the time comes, several companies will be ready and able to do the job. The question is: Are you ready to clone your pet? Brett Reggio is betting on it.He is working on his Ph. D at Louisian State University. He's successfully cloned a goat five times and wants to try the process on family pets. So he started a business called Lazaron. "What Lazaron provides is the first step in the cloning process. "He said."It's for curing and storing the fiberglass cells that will be used for cloning." "Your first reaction is yeah! I think I'd like that." said Donna Schacht, a pet owner. "I don't believe you can ever replace a special love," pet owner Paulette Callattion said. Most pet owners will tell you freezing your pet's DNA in hopes of one day cloning it is a personal decision. Scientists say that cloning your own pet doesn't mean that the offspring will have the same intelligence, temperament or other qualities that your pet has. Question: From the passage we know that scientists have _ . Options: A: tried to clone animals B: cloned many kinds of animals C: been able to clone pets for people D: once cloned goats successfully
