"A rolling stone gathers no moss ," but there is one living animal that does gather moss -- the three-toed sloth of South America. This slowest-moving member of the animal kingdom is so inactive that moss actually gathers on its body and turns it green -- strange as it seems! Most of the sloth's life is spent motionless, hanging upside down from a limb . And that is the way its hair grows. Long and coarse, the strands from receptacles for the damp jungle algae turn the brown fur a mossy green. Actually this moss helps the animal survive because it serves as a perfect camouflage against the leafy trees and hides the sloth from the jungle's swift-moving hunters. The sloth would have little chance of survival on the ground. With long, curved claws hooded over the limb of a leafy tree, it spends the long hot hours during the day drowsing and eating. Inch by inch, it strips the leafy limbs bare and crawls slowly down the trunk to find a new dining spot, but only at night. In addition to looking rather like a vegetable, the sloth is a strict vegetarian. Running out of its favorite leaf is about the only thing that will make a sloth move. Then its appetite may even force the animal into swimming a stream to reach a succulent . It will also force it into fighting to keep the tree all to itself. The sloth is lazy and prefers to be alone, but it will tolerate its own s! According to the passage, the sloth will move about when _ . A) It senses a coming danger. B) it is forced to swim in a hot day. C) it is short of its favorite food. D) it wants to keep the vegetable to itself.

Don't invite crime--take basic, sensible precautions. Your house and possession are valuable and must be properly protected. When you buy a lock, you buy time --- and this is the one thing a burglar can't afford. Most thieves are casual opportunists to whom the best deterrents are delay and noise which could mean discovery. When you leave it, lock it! First of all, fit security locks to all doors and windows and a safety chain on the front door. Secondly, use them! If you have any ladders or tools, don't leave them lying about in the garden, lock them away. "Safe" or "secret" places for keys and valuables are not reliable - nine times out of ten, they are the first place a thief will look. When you move house... When you move into a new home even if it is fitted with security locks, change them. You don't know who else may have keys. Never let strangers into your house. An official - looking cap is not enough, ask for proof of identity and look at it carefully - if you are still not satisfied, don't let the person in. Valuables need special protection Valuables should really be given special protection - preferably by leaving them with your bank. A small security safe works too, but not to the most determined burglar. It is also important to keep an up - to - date list of valuables and their descriptions. In the case of fine art, paintings, or jewelry, color photographs can sometimes be of assistance to the police if you are unfortunate enough to have them stolen. Enter the details on the back of the pictures. But don't keep such documents in your house, keep them at the hank or with your insurance company. Going on holiday? Don't talk about your holidays and future plans loudly in public. Do remember to cancel the milk and newspapers and also to draw curtains back.

What is more important to a high school student than being popular? Anyone who has ever gone to high school or at least seen a John Hughes' movie knows the answer to that question. When Theresa Sommers first discovered MySpace three years ago, the teen from Minneapolis, St. Paul thought she had found the real high school popularity contest. She could spend hours a day creating an online picture, finding cool pictures and music to make her page look more beautiful, and looking for interesting-looking people to be her online friends. And along the way, she could compete with her friends to see who had the most friends or most-visited page. The more she used the site, however, the less interested she became in only being popular; she started using her time for more heartfelt conversations with friends and went more deeply into her personal interests. As a beginner in taking pictures, she put her best pictures on the site and looked for advice from people who are good at taking pictures. At the same time,she began to get in touch with the students of the colleges she wanted to go to. She opened up a new account on Facebook. And she even began to put some of her own creative writing on the website and would ask for advice on homework from her friends. She asked them," How long did you spend on your homework?" or "How would you write it?" Often she would put her homework online. What's a John Hughes' movies most probably about? A) Stories of successful people. B) How to do well in exams. C) Life of high school students. D) How to make friends online.
