The scene in the Hollywood movie The Day After Tomorrow, when global warming could soon turn the global climate into a new ice age, may never occur, according to a 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 data 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 – 40℃, 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 data 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.

1.In drilling through the ice in Antarctica, scientists have found that______.

A. the lowest temperature there is – 40℃

B. the depth of ice is 3,000 meters

C. the ice has existed for 15,000 years

2.The information of the global climate conditions in the past can be obtained through______.

A. separating carbon dioxide from the air

B. examining the growth rings of trees

C. comparing temperatures in different areas

D. studying the ice and air caught in each layer

3.We can infer from Eric Wolff's words that_______.

A. there is something wrong with the data

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

A. Research over the Antarctic area.

B. Warm period to last about 15, 000 years.

C. Report on the eight ice ages in the past.

D. Hollywood movies and the global climate.

New findings from Queen’s University biologists show that in the plant world, bigger isn’t necessarily better.

“Until now most of the thinking has suggested that to be a good competitor in the forest, you have to be a big plant,” says Queen’s Biology professor Lonnie Aarssen. “But our research shows it’s virtually the other way around.”

Previous studies showed that larger plant species monopolize(垄断) sunlight, water and other resources, limiting the number of smaller plant species that can exist around them. But the research has proved that this is not generally the case in natural vegetation.

In the Queen’s project, PhD student Laura Keating targeted the largest “host plants” of 16 woody plant species growing in the Okanogan Valley, British Columbia. The research team calculated the number and variety of plants that neighbored each large host plant. They then randomly selected plots without host plants and calculated the plant species there as well. The research showed that the massive trees have no effect on the number of species with which they coexist.

Smaller plants have many advantages over their overbearing neighbors, Professor Aarssen notes. Larger species generate physical space niches under their shelters where smaller species grow well. Smaller plants are much more effective than large trees at using available resources. They also produce seeds at a much younger age and higher rate than their bigger counterparts, and settle down much more quickly—thus competing with the newly-born plants of larger species.

3.What can we learn according to the text?

A. Larger plant species limit the number of smaller ones around them.

B. Smaller plants can limit the number of plant species around them.

C. Smaller plants produce seeds at a higher rate than their bigger counterparts.

D. Larger trees are more effective than small plants at using available resources.

Modern science suggests that a healthy lifestyle matters much to how long you can live and how well you live. Here are some tips for you to form a healthy lifestyle.

Keep a scientific diet. Keep in mind that sugar can be removed from our diet completely. Over intake of sugar is one of the main reasons for getting fat. Over intake of protein or fat and low intake of fiber can also lead to getting fat. We need only a few grams of protein every day to keep our body in order. Like rain to crops, not the more the better.

Be always in a good mood. There is a relation- ship between the mood and health. A good mood keeps you in high spirits. Thanks to the internet, we can enjoy and learn much without going out. Take a look at some online shops and pick up some bargains, enjoy music and movies and chat with some good friends. Just keep happy.

Enough sleep. Two studies show the reasons why teens and adults don’t have enough sleep. With teens, a major reason is mobile phone use; with adults, it’s work. Meanwhile, a third study of young children shows that a lack of sleep in early life may lead to serious problems in future. Everyone needs at least 8-hour sleep to recover from tiredness and the hurt caused by hard work in the daytime.

Proper exercise. Do exercise to keep away from fatness. Because of the quick pace of modern life, you don’t have time to do exercise every day, but at least three times a week and 45 minutes each time.

1.The author wrote the passage to _____.

A. tell the readers how to take proper exercise every day

B. provide some advice on how to form a healthy lifestyle

C. ask people to care about their health rather than their work

D. make some surveys among those who have health problems

2. Which of the following can lead to getting fat according to the passage?

A. low intake of protein.B. low intake of fat.

C. over intake of fiber. D. over intake of sugar.

3. The main reason why teenagers don’t have enough sleep is that they _____.

A. use mobile phones too much

B. have too much homework

C. eat too much sugar every day

D. don’t have enough exercise

4. How many minutes do you need to do exercise at least every week?

The music of your teenage years probably will stay with you for the rest of your life.I think music is deeply connected with memory because of the emotions it awakens.Music also helps to mark time because of the way the fashions and stars of pop culture come and go.I often connect some summers with particular records (唱片 ) that came out while I was on holiday.But what's really the best way to record your youth? Is it your favorite song, or a picture of the singer?

In my teenage years, one of the special things about Britain was the huge amount of information about music.There were 3 weekly newspapers about music：Sounds, Melody Maker and the New Musical Express.Buying records was expensive and it also meant making a choice.So it was wise to read about music instead, and in some ways, it was actually better as well.It was possible for a group to get onto the front cover of one of the music papers without even having made any records—but they needed things to say for the reporters to write about.In fact, the best pop stars of the 1980s were people whose main talent was exactly that.They weren' t great musicians or singers and they weren't especially good?looking, but they had some unusual acts or habits and a nice way with clever phrases.They were ideal for filling music papers.

When The Face magazine first came out in May, 1980, it was meant to be a rock magazine.I have given away or sold all the records I bought as a teenager, but I think my old copies of The Face will stay with me for ever.Although it started out as a source of information about music, the writers quickly realized that it wasn't really the music that was important—it was the way people spoke and acted, and, above all, the way they looked.

3.According to Paragraph 2，during the author's teenage years，________.

A．people had few chances to buy records

B．it was hard to judge whether records were good or not

C．it was not an easy thing for teenagers to get records

D．the choice of buying records only depended on newspapers

4.The underlined word “that” in Paragraph 2 means that ________.

A．people could get onto the music papers without having made any records

B．people's talent was not what reporters needed to write about

C．reporters wrote about the talents of pop stars
