Blue whales are the largest animals ever known to have existed on the planet, and they can grow to a length of 100 feet and weigh more than 330,000 pounds. But recently researchers have found that these whales are on the move and they have migrated from California waters to areas off Canada and Alaska for the first time since commercial whaling ended in 1965.

The researchers identified 15 blue whales that have appeared off the coast of British Columbia and the Gulf of Alaska since 1997. Four of these whales were recognized as ones that were once sighted off California shores, suggesting that the whales are returning to an old migration pattern between the coasts.

Before commercial whaling began in the early 1900s, blue whales were found widely throughout the North Pacific and California waters. But from the 1920s to the 1960s,whaling severely reduced the whale populations. Blue whales never recovered in the Northern Pacific, making sightings in this area rare. However, much larger groups of whales have been observed close to California since the 1970s.

The scientists had previously thought that the California population was separate from the population that had historically lived in North Pacific waters. But the current study shows that whales off the coast of British Columbia and the Gulf of Alaska are likely part of the California population.

To identify the blue whales, the researchers looked at photos of cetaceans taken in the North Pacific Ocean and compared them with a library of blue whale pictures taken along the West Cost of the United States and Southern Pacific. Up to now, the researchers are not quite sure why the whales are changing their migration patterns, but they suspect that the whales may be following their food moving farther north by the changes in ocean conditions.

1.According to the passage, blue whales are .

A. following a fixed route of migration

B. dying out due to commercial whaling

C. moving from the south to the north

D. rarely found in the Southern Pacific

2.The whale population in the northern Pacific .

A. is different from the California population

B. is probably part of the California population

C. has become the largest group since the 1970s

D. has lived there since the 1960s

3.The underlined word "cetaceans" in Paragraph 5 probably means .

A. land creatures B. whale species

C. ocean conditions D. migration patterns

4.What might make blue whales migrate according to the researchers?

A. Commercial whaling. B. Weather conditions.

C. Life reproduction. D. Food resources.

Some of the world’s most significant problems never hit headlines. One example comes from agriculture. Food riots (暴动)and hunger make news. But the trend lying behind these matters is rarely talked about. This is the decrease in the growth in production of some of the world’s major crops. A new study by the University of Minnesota and McGill University in Montreal looks at where, and how far, this decline is occurring.

The authors take a vast number of data points for the four most important crops: rice, wheat, corn and soyabeans. They find that on between 24% and 39% of all harvested areas, the improvement in production that took place before the 1980s slowed down in the 1990s and 2000s.

There are two worrying features of the slowdown. One is that it has been particularly sharp in the world’s most populous countries, India and China. Their ability to feed themselves has been an important source of relative stability both within the countries and on world food markets. That self-sufficiency (自给自足) cannot be taken for granted if productions continue to slow down.

Second, production growth has been lower in wheat and rice than in corn and soyabeans. This is problematic because wheat and rice are more important as foods, accounting for around half of all calories consumed. Corn and soyabeans are more important as feed grains. The authors note that “we have preferentially focused our crop improvement efforts on feeding animals and cars rather than on crops that feed people and are the basis of food security in much of the world.”

The report also states the more optimistic findings of another new paper which suggests that the world will not have to dig up a lot more land for farming in order to feed 9 billion people in 2050, as the Food and Agriculture Organisation has argued.

Instead, it says, thanks to slowing population growth, land currently ploughed(犁)up for crops might be able to revert (回返) to forest or wilderness. This could happen. The trouble is that the prediction assumes continued improvements in productions, which may not actually happen.

1.What significant problem does the writer think we should pay more attention to?

A. The decline of the grain production growth

B. News headlines in the leading media.

C. Food riots and hunger.

D. The food supply in populous countries.

2.Why does the author mention India and China in particular?

A. Their big populations are causing worldwide concerns.

B. Their food yields have begun to decrease sharply in recent years.

C. Their self-sufficiency is vital to the stability of world food markets.

D. Their food self-sufficiency has been taken for granted.

3.What does the new study by the two universities say about recent crop improvement efforts?

A. They fail to produce the same remarkable results as before the 1980s.

B. They contribute a lot to the improvement of human food production.

C. They play a major role in guaranteeing the food security of the world.

D. They focus more on the increase of animal feed than human food grains.

4.What does the Food and Agriculture Organisation say about world food production in the coming decades?

A. The growing population will greatly increase the pressure on world food supplies.

B. The optimistic prediction about food production should be viewed with caution.

C. The slowdown of the growth in yields of major food crops will be reversed.

D. The world will be able to feed its population without expanding the area of farmland.

5.How does the author view the argument of the Food and Agriculture Organisation?

A. It is built on the findings of a new study.

B. It is based on a doubtful assumption.

C. It is backed by strong evidence.

D. It is open to further discussion.

Summer Rain

The worst days of any summer are the rainy ones. We spend all year looking forward to nice weather and long, hot days. All of winter, with its cloudy days and bitter cold, we dream of those endless days at the beach, lying on the sand and enjoying the bright and burning sun. And then, summer comes, and it rains.

As a child, I would wake up to rainy summer days and come close to crying. It wasn’t fair. We suffered through months of school and experienced bad weather for those short ten weeks of freedom and pleasant weather.

On those rainy summer days, I had nothing fun to do and could only sit inside, staring out at the rain like a bird in a cage. I was an only child, so there was no one else to play with. My father worked from home, so I was not truly alone, but he could not actively play with me since he was at work. It was those days that I would watch whatever was on television or read any books that I could find lying around. I’d drag through the day and pray each night that the rain would not be there the next day.

As an adult, though, my opinion of summer rain has changed. When you have to work every day, summer is not as exciting. Everything seems dull. Such a mindset makes you cheer for anything new or different. I spend the winter dreaming of summer and the summer dreaming of winter. When summer comes, I hate how hot it is. And then I look forward to the rain, because the rain brings with it a cold front, which makes me comfortable. Rainy days are still the worst days of the summer, but summer rain today means positively beautiful — and considerably cooler — weather tomorrow.

1.When the author was a child, he ______.

A. preferred cooler weather

B. hated rainy days

C. liked staying indoors

D. dreamed on summer days

2.We can learn from the passage that the author ______.

A. was often left alone at home

B. preferred reading to playing outside

C. had no brothers or sisters

D. could enjoy the brilliant sun in winter

3.As an adult, the author views summer rain differently because ______.

A. he knows it won’t last long

B. his summer holiday is very short

C. he can better deal with his holiday

D. rain makes the weather cooler
