global climate (气候) into a new ice age, may never occur, according to new research.
The next ice age could be 15,000 years away, say European scientists who last month announced a
continuous record of 740,000 years of climate date (数据) obtained from the Antarctic ice.
Scientists from 10 nations have now almost completely drilled through a 3,000-meter depth of ice high in
the Antarctic mainland. They figure out that the area where summer temperatures can fall to, has at least
900,000 years of snowfalls, kept as neatly as the growth rings of a tree. And the ice and air caught in each
layer (层) have begun to answer questions about the climates in the past.
The results show that there have been eight ice ages in the past 740,000 years and eight warmer periods.
And by comparing the pattern of global conditions today with those of the past, the researchers reported in
Nature that the present warm period could last another 15,000 years.
Research suggests that there is a very close connection between greenhouse gas levels and global average
temperatures. It also shows that carbon dioxide (二氧化碳) levels are the highest for at least 440,000 years.
"If people say to you: the greenhouse effect is a good thing because we would go into an ice age
otherwise, our date say no, a new ice age is not hanging over our heads," said Eric Wolff from the British
Antarctic Survey." Now we have eight examples of how the climate goes in and out of ice ages … and you
can learn what the rules are that go into the climate models that tell us about the future."
Scientists found that whenever temperatures rose in the frozen record, so did carbon dioxide level. " In
440,000 years we have never seen greenhouse gas get as thick as it is today," said Dr Wolff.
A. the lowest temperature there is
B. the depth of ice is 3,000 meters
C. the ice has existed for 15,000 years
D. snowfalls are kept in certain patterns
B. examining the growth rings of trees
C. comparing temperatures in different areas
D. studying the ice and air caught in each layer
B. greenhouse effect is always a bad thing
C. a new ice age will not come in the near future
D. greenhouse gas will get thick in the future
B. Warm period to last about 15,000 years.
C. Report on the eight ice ages in the past.

won"t be for long. Miami"s Mark Shantzis has made it simple for those living in tall buildings to use the chute
and recycle too.
In Shantzis" Hi-Rise Recycling System, a chute leads to a pie-shaped container with six boxes that can turn
around when operated. The system, which fits in the same space as the chute and container now in use,
enables glass, plastic, paper, metal, and other rubbish to go into separate boxes.
The system is controlled from a board next to the chute door. The board has a button for each class of
recycling materials (as well as for unrecyclables). At the press of a button, a microcomputer locks all other
floors" chute door and sets the recycling container turning until the right box comes under the chute. The
computer also counts the loads and gives a signal by phone when the box is full. And a particular piece of
equipment breaks up the nonrecyclables
Sorting (分类) recyclables before they are collected saves the use of expensive materials recovery
equipment which otherwise has to do the sorting. Such equipment often makes recycled materials very
expensive, so expensive that tons of recyclables remain wasted. Shantzis believes his system could help
recycled materials become more cost-effective.
B. to introduce a recycling system for high rises
C. to describe the use of computer technology in recycling
D. to explain the need for rubbish collection in high rises
B. rubbish chutes will become out of date before long
C. you won"t wait long for your turn to recycle rubbish
D. it won"t be long before you"ll have to recycle your rubbish
B. check if the container is full
C. press the correct button
D. break up the rubbish
B. it saves time and space
C. it saves money for people living in high rises
D. it makes better use of the existing recovery equipment

| You can make the difference between this…and this This summer, join the International Conservation Scouts on a fun-filled holiday with a difference. Year after year, young people from all around the world get together at one of our sixteen conservation (环境保护) camp. Their shared aim? To help protect the countryside and its wildlife. Many animals and plants are in danger of disappearing forever. The dormouse, a kind of mouse, for example, needs woodland plants for food and trees to stay in. Its habitat (栖息地) is being destroyed by man and it needs our help to survive. On a conservation camp holiday you will learn all about nature and how to protect it. Our trained leaders will accompany you and tell you everything you need to know. Because of this you don" t need any experience, just energy and enthusiasm. You will explore the countryside and work to ensure the survival of hundreds of animals and plants and still have plenty of time to enjoy the camp"s excellent sports facilities and organized nature paths through beautiful scenery. The International Conservation Scouts is a worldwide organization, so there must be a camp near you, You can spend a splendid holiday at any of the camps for as little as f 60 including accommodation and food.

| It"s happened to all of us: we sleeplessly toss (翻转) and turn while the person next door snores (打呼噜) his way through the night. "Millions of people snore, most of whom are men over the age of 20," said Robert Bone, chief of Head and Neck Surgery at Scripps Clinic in San Diego."As many as 45 percent of people snore, and as many as 25 percent are chronic (慢性的) snorers. Male snorers far outnumber women who snore." To help chronic snorers get a good night"s sleep, Dr. Bone treats his patients with Somnoplasty, a now-proven procedure that he created at Scripps Clinic six years ago. "If you snore loudly and frequently and do not have other breathing disorders, Somnoplasty may be the solution for you," he said. Somnoplasty uses low-temperature radio waves to treat a well-defined area in the soft palate (鄂). A small prong is inserted into the mouth toward the back of the throat. Then radiofrequency energy is delivered beneath the surface of the soft palate. The treated part is heated just enough to create an area of coagulation(凝结物). Over the next four to six weeks, the body naturally tears off the treated part, reducing volume and solidifying the area that is responsible for snoring. The procedure takes place in the doctor"s office, and typically lasts no longer than 15 to 20 minutes. Patients need two to four treatments, and the procedure is 80 percent effective. Treatment costs only $200 to $300 and is covered by some insurance. Dr. Bone treats about 800 patients a year. "Somnoplasty is the state-of-the-art procedure for snoring," Dr. Bone said. "It can provide much-needed relief to chronic snorers and their families." For more information or to schedule an appointment, call (858) 554-8964. | |||

| We"ve all seen them: perfectly toned famous people on late-night television telling us that we too can develop rock-hard abdominal muscles (腹肌). It"s easy! Just pay $149.99 for the Torso Track or $149.75 for the Ad-Doer and watch those unwanted inches leave your waist. Americans spend tens of millions of dollars on various products to firm up their fat around the waist. And did they work? Not necessarily. Independent studies have concluded that most of these products-no matter who approved them or how expensive they are-shape your midsection no better than old-fashioned stomach crunches (仰卧起坐). Some can even cause injury- like the $518.99 Body Shaper-Q8SP, which left electrical burns on some researchers at the University of Wisconsin, La Crosse. Others, like the popular Ab-Doer, typically burn less energy than a gentle walk, according to a study to be published in September by the American Council on Exercise. The fact is that many Americans don"t have the biological makeup to develop an obvious abdominal muscles. They are either unable to get the necessary muscle mass or they can"t lose enough fat to make a difference. Even if the underlying muscles are well developed, all it takes to hide it is one-sixteenth of an inch of fat. That"s enough to exclude most healthy women as well as plenty of guys who do crunches every day. So what works best? In its new study, the exercise experts researched on the results of the popular Ab-Doer. A lengthy TV advertisement promises that just 10 minutes a day performing such movements as "Body Boogies" and "Good Mornings" will "help form those muscles the fun and easy way without diets." Steven Loy, professor at California State University, Northridge, tested the promise by measuring the electrical activity produced by the abdominal muscles during three Ab-Doer movements. He and his colleagues then compared the results with those produced during traditional exercises. They determined that the muscles were no more active, and in some cases less so, when exercisers were using the Ab-Doer. Taking a broader approach, researchers at San Diego State University compared 13 abdominal exercises for their ability to develop the central abdominal muscles. They concluded, in a report published in May, that the most effective exercises kept turning the body and worked the muscles the entire time. Among the winners: the bicycle movements-so called because it looks as if you are riding a bike while lying flat on the floor-and exercises performed on the "Captain"s Chair", a product typically found in gyms that helps hold the body in the air while you raise your legs up toward your chest. Researchers suggested that a varied routine of the different exercises could deliver the best results. | |||

| A. Torso Track. B. Ab-Doer. C. Captain"s Chair. D. Body Shaper-Q8SP. | |||
| 2. According to the author, it"s difficult for many Americans to get visible firm abdominal muscles mainly because _____. | |||
| A. they do not put in enough efforts B. injuries interrupt their exercise frequently C. they change their exercise routine regularly D. how big their muscles will be is determined by birth | |||
| 3. The author convinces the readers by _____. | |||
| A. describing successful cases B. offering professional suggestions C. presenting findings of researches D. comparing advertisements of products | |||
| 4. What"s the main purpose of this passage? | |||
A. To research and develop in order to create the perfect stomach and exercise machine. |
