Since English biologist Charles Darwin (1809 –1882) published On the Origin of Species in 1859, scientists have vastly improved their knowledge of natural history. However, a lot of information is still the subject of speculation, and scientists can still only make educated guesses at certain things.
One subject that they guess about is why some 400 million years ago, animals in the sea developed limbs (肢) that allowed them to move onto and live on land.
Recently, an idea that occurred to the US paleontologist (古生物学家) Alfred Romer a century ago became a hot topic once again.
Sea animals would have been forced into these pools by strong tides. Then, they would have been made either to adapt to their new environment close to land or die. The fittest among them grew to accomplish the transition (过渡) from sea to land. Romer thought that tidal pools might have led to fish gaining limbs.
Romer called these earliest four-footed animals “tetrapods” (四足动物). Science has always thought that this was a credible theory, but only recently has there been strong enough evidence to support it.
Hannah Byrne is an oceanographer (海洋学家) at Uppsala University in Sweden. She announced at the 2018 Ocean Sciences Meeting in Oregon, US, on Feb 15 that by using computer software, her team had managed to link Romer’s theory to places where fossil deposits (化石沉积) of the earliest tetrapods were found.
According to the magazine Science, in 2014, Steven Balbus, a scientist at the University of Oxford in the UK, calculated that 400 million years ago, when the move from land to sea was achieved, tides were stronger than they are today. This is because the planet was 10 percent closer to the moon than it is now.
The creatures stranded in the pools would have been under the pressure of “survival of the fittest”, explained the UK’s University of Bangor ocean scientist Mattias Green. As he told Science: “After a few days in these pools, you become food or you run out of food … the fish that had large limbs had an advantage because they could flip (空翻) themselves back in the water”.
As is often the case, however, there are others who find the theory less convincing. Cambridge University paleontologist Jennifer Clark, speaking to Nature magazine, seemed unconvinced. “It’s only one of many ideas for the origin of land-dwelling (陆地栖息的) tetrapods, any or all of which may have been a part of the answer,” she said.
1.Who first proposed the theory that fish might have gained limbs because of tidal pools?
A. Charles Darwin. B. Alfred Romer.
C. Hannah Byrne. D. Steven Balbus.
2.Why were tides stronger 400 million years ago than they are today according to Steven Balbus?
A. Earth moved faster than it does today.
B. Earth was closer to the sun than it is today.
C. Earth was closer to the moon than it is today.
D. Earth had larger oceans than it does today.
3.What does the underlined word “stranded” in Paragraph 8 mean?
A. Trapped. B. Settled.
C. Survived. D. Adapted.
4.What is the focus of the article?
A. The proposal of a new scientific theory.
B. The arguments over a scientific theory.
C. Some new evidence to support a previous theory.
D. A new discovery that questions a previous theory.
Not many women have won the Nobel Peace Prize. Until 2004, no African woman ever had. That was when Dr. Wangari Maathai won it — for planting trees. You might ask, what do trees have to do with peace? “Many wars are fought over resources (资源),” Dr. Maathai said as she accepted the prize. “If we conserve resources better, the fighting will stop.”
Dr. Maathai was born in Kenya in 1940. Unlike most African women, she went to school. High school woke up a hunger in her for more knowledge. She went to college in Kansas and earned a master’s degree in science from the University of Pittsburgh. She became the first Kenyan woman ever to earn a Ph.D. Later, Dr. Maathai taught animal science at Kenya’s University of Nairobi.
As an educated woman, Dr. Maathai feels responsible for leading others. Dr. Maathai started her work in 1977 by planting nine trees in her backyard in Kenya. Trees are important in Africa for several reasons. First, they keep soil from eroding (流失) into streams, thus cutting down on pollution and improving the soil. Second, trees provide firewood. So many trees have been cut down in Africa that women must walk far from home to find wood for cooking. New trees can also keep deserts from spreading.
Dr. Maathai’s Green Belt Movement pays local women for every tree they plant that is still alive three months later. In its first 15 years, the Green Belt Movement employed at least 50,000 women and planted more than 10 million trees. Following Dr. Maathai’s example, the Kenyan government increased its own tree-planting efforts. The movement has spread to 30 countries in Africa. When the land and people’s lives have improved, Dr. Maathai says, peace will follow.

Driving in Canada is similar to driving in many parts of the United States. Distances and speeds, however, are posted in kilometers per hour and some signs, particularly in Quebec, may only be in French.
Unless otherwise posted, the maximum (最大限度的) speed limit in Canada is 50km/hr in cities and 80km/hr on highways. On rural highways, the posted speed limit may be 100km/hr. It is illegal to take automobile radar detectors (汽车雷达检测器) into Quebec, Ontario, Manitoba, and the Yukon. Seat belt use is required by law for all passengers, and child car seats must be used by children under 40 pounds. Some provinces require drivers to keep their vehicles’ headlights on during the day and some have banned (禁止) driving while using a hand-held cell phone. Motorcycles cannot share a lane (车道), and safety helmets for motorcycle riders and passengers are necessary. Running a red light is a serious crime throughout Canada and drivers are advised to stop before starting when a light turns green.
Winter travel can be dangerous due to heavy snowfalls and icy conditions. Some roads and bridges are often closed in winter. Snow tires are required in some provinces. Travelers should also be careful about animals while driving at night in rural areas.
Highway 401, from Detroit to Montreal, is one of the busiest highways in North America. It has been the scene of many deadly traffic accidents due to sudden and severe weather changes, high rates of speed, and heavy truck traffic. Thus drivers should be alert while travelling here.
Please refer to our Road Safety page for more information. Also, we suggest that you visit the website of Canada’s national authority responsible for road safety.

A. careful B. relaxed
C. nervous D. pleased

A. Different traffic rules in Canada
B. Tips for traveling by car in Canada
