Ques: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... What is the most probable purpose of the new invention? A) To improve people ' s life standard. B) For scientific research. C) For commercial benefits. D) For safety reasons.

Ques:One day, when old Jacob and little Jacoble were walking home, the sun began to go down. Old Jacob was thinking of his house and little Jacoble didn't know what to think. Then he thought of a wonderful idea, and he cried, "Jacob! Do you know what I saw yesterday? I saw a green rabbit. It was flying in the air and it was so big, even bigger than an elephant!" "You saw that with your own eyes?" asked old Jacob. "Of course I did," said Jacoble proudly. "It's a good thing that you really saw that big, flying, green rabbit," said old Jacob, "because that old bridge we are going to walk over is a very strange one. As soon as anyone who hasn't told the truth comes on it, the bridge breaks in two." They continued walking. "Jacob," said Jacoble a little later, "you know that big, green, flying rabbit I saw yesterday ... Well, it wasn't really flying, and ... it wasn't quite as big as an elephant ... but it was very big, about the size of a horse!" "Big as a horse?" asked Jacob as they got closer to the bridge and little Jacoble began not to feel so well. "Jacob," said Jacoble. "That big, green rabbit I saw yesterday, well, I had something in my eye and so I couldn't see that well. It wasn't a very big rabbit but it was green. Yes, that's what it was -- all green!" Old Jacob didn't say a word. He just walked over the bridge. But Jacoble didn't go after him because he was afraid and he knew why he was afraid. He stood at the bridge and said, "Oh, Jacob! You know that rabbit I saw yesterday. It wasn't green. No. It was just a little, brown rabbit." Then he was not afraid of anything any more and he ran happily over the bridge. Jacob considered Jacoble's story   _  . A) humorous B) interesting C) frightening D) unbelievable

Ques:"Tom!" There was no answer. "Tom!" Still no answer. "Where's that boy gone? Tom!" The old lady looked all around the room. She looked under the bed, but found only the cat. "If I catch that boy, ..." she murmured to herself. She opened the door and looked out into the garden. "Tom!" she shouted. Then she heard a slight noise behind her. She turned round just in time to catch the boy as he came out of a cupboard. "And what have you been doing in there?" "Nothing," said the boy. "Nothing! Look at your hands and your mouth! What is that stuff?" "I don't know, Aunt." "Well, I know. It's a jam. I've told you forty times that if you touched that jam, I'd _ you. Give me that stick." "Look out, Aunt! Look behind you!" The old lady turned round and Tom was out of the door in a flash, over the garden fence and away. "Damn that boy! Will I never learn? He's always playing tricks on me. And he seems to know just now how far he can go, too. But I can't take a stick to him. I really can't. After all, he's my dead sister's boy. Ah well, he'll play truant today and I'll have to make him work tomorrow." At supper Aunt Polly tried to trick Tom into admitting that he hadn't gone to school. "It was rather hot today, wasn't it, Tom?" "Yes," answered Tom. "You didn't have to open your shirt collar where I sewed  it, then." Tom was confident, now. He opened his jacket. His collar was securely sewed. "Oh Tom," said Aunt Polly. "You're a good boy really." She was sorry that she had been wrong about him. "But Aunt," came a voice. It was Sidney, Tom's younger brother. "Didn' t you sew Tom's collar with white cotton? Look! Now it's black. Tom was already running out of the door. ---The Adventures of Tom Sawyer by Mark Twain Which of the following is TRUE according to the passage? A) Tom's mother passed away.
