参考技术A Level 5 Unit 3 Part 4-Learning Magnetic Field Reversal

磁场翻转; 磁场逆转;

1.Scientists now believe that the Earth's magnetic field is about to reverse.

2.This is called magnetic field reversal.

3.Every 200,000 to 300,000 years, the Earth's magnetic field reverses.

4.In other words,the North and South magnetic poles switch places.

5.This has happened many times in Earth's history,but it has been happening more lately.

1.Recent research provides evidence that there have been five magnetic reversals during the past 500,000 years.

2.The most recent event happened approximately  41,000 years ago. (大约)

3.Recent studies have found that the Earth's magnetic field has weakened about 5% per decade.

4.At its current rate,the next reversal could happen within the next century.

1.Some people worry about the effects of a magnetic field reversal.

2.They think there is a possibility that it could cause many problems.

3.For example,without a magnetic field,communications could be disrupted.

4.Birds and other forms of life could become confused and get lost.

5.Another effect would be an increase in some forms of cancer, especially skin cancer.

6.This would be because of an increase in the amount of radiation absorbed by out bodies.

1.The possibility that a field reversal would be an extinction event is very low.

2.There is very little historical evidence to show that previous reversals have caused extinctions.

3.Humans have been on Earth for millions of years,during which there have been many reversals.

4.Therefore,scientists believe that any changes would be temporary.

5.Another theory is that the Earth's outer layer could rotate around the liquid metal outer core that makes up most of the earth.

6.So in the next reversal,continents could shift positions,from north to south.

7.Imagine, if that happened,Australia would be in the northern hemisphere !(n.半球)

1.With so many theories,how can we know what to believe?

2.This is important because some events require us to act well in advance.

3.Otherwise, it will be too late to prevent a catastrophe .(大灾难)

Malaysia bets on durian as China goes bananas(crazy) for world‘s smelliest fruit

The stinky, spiky durian is set to become Malaysia‘s next major export as the Southeast Asian nation rushes to develop thousands of acres to cash in on unprecedented demand for the fruit from China.

Once planted in family orchards and small-scale farms, the durian, described by some as smelling like an open sewer or turpentine when ripe, is attracting investments like never before. Even property tycoons and companies in palm oil, Malaysia‘s biggest agricultural export, are making forays into the durian business.

The Malaysian government is encouraging large-scale farming of durian, counting on a 50 percent jump in exports by 2030.

Chinese pay top dollar for Malaysia‘s ‘Musang King‘ variety of durian because of its creamy texture and bitter-sweet taste. Prices of the variety, now planted all over the country, have nearly quadrupled in the last five years.

China‘s durian imports rose 15 percent last year to nearly 350, 000 tonnes worth $510 million, according to the United Nations‘ trade database. Nearly 40 percent was from Thailand, the world‘s top producer and exporter.

Malaysia accounted for less than 1 percent, but expects sales to China to jump to 22, 061 tonnes by 2030 from this year‘s likely 14, 600 tonnes, as trade is widened to include whole fruit from the current restriction to durian pulp and paste.

M7 Plantation Bhd, a private company established last year, is developing a 10, 000-acre durian estate in Gua Musang, home to the Musang King in the eastern state of Kelantan, and is selling durian trees for 5, 000 ringgit ($1, 200) each.

"We founded the company because we see potential in the industry, the primary target being China, " Chief Executive Ng Lee Chin said, adding that most of her buyers were from China.

 

马来西亚“押宝”榴莲，因为中国人为世界上最臭的水果疯狂

奇臭无比、浑身长刺的榴莲有可能成为马来西亚的下一个主要出口产品，因为这个东南亚国家急于开发数千英亩的土地，以在中国对榴莲的空前需求中牟利。

榴莲，曾经种植在家庭果园和小型农场中，被一些人描述为“成熟的时候闻起来就像露天的臭水沟或松节油”，但它正吸引着前所未有的投资。就连地产大亨和棕榈油（马来西亚最主要的出口农产品）公司也在进军榴莲行业。

马来西亚政府正鼓励大规模种植榴莲，预计到 2030 年，榴莲出口量将增长 50%。

中国人愿意花高价购买马来西亚“猫山王”品种的榴莲，因为这类榴莲拥有奶油般的质感和甜中带苦的口感。猫山王目前已在马来西亚全国各地种植，在最近五年里，这一品种的价格几乎翻了两番。

根据联合国贸易数据库的信息，去年中国的榴莲进口量增长了 15%，达到近 35 万公吨，价值 5.1 亿美元。其中近 40% 的进口量来自泰国，泰国是世界上最大的榴莲生产国和出口国。

来自马来西亚的榴莲占比不到 1%，但预计到 2030 年，马来西亚对华出口的榴莲销售量将从今年的大约 14,600 公吨猛增至 22,061 公吨，因为贸易范围将扩大到整只榴莲，而不仅限于目前的榴莲果肉和榴莲酱。

马来西亚 M7 种植公司是一家去年成立的私人企业，它正在话望生开发一座占地 1 万英亩的榴莲庄园，地点设在凯兰丹州东部的“猫山王”原产地，除此之外，它还以每棵 5,000 林吉特（1,200 美元）的价格出售榴莲树。

“我们之所以创立这个公司，是因为我们看到了榴莲行业的潜力，我们的主要目标是中国。” 首席执行官 Ng Lee Chin 这样说道，她还补充称，她的大部分买家都来自中国。
