There are about 1,200 species of bats in the world, Swartz says. Some eat fruit. Others eat insects or honey. And just a few drink blood.

Some bats use their eyes to see where things are. Others collect information about their surroundings by bouncing sound off objects and listening to the echoes (回声).

But what all bats have in common (other than being the only flying mammals in existence) are flexible (灵活的) wings that enable them to change directions quickly. If youve ever seen bats flying with a rush through the air in the early evening, you probably noticed how suddenly they could change directions.

Scientists have long assumed (设想) that bats fly the same way as birds and insects do—with firm, airplane-like wings that connect to the shoulder. The problem with that assumption, however, is that bats arent birds or insects. As mammals, they have more in common with people, horses and dogs than with other flying creatures.

For example, birds have bones which are empty inside, and insects have no bones at all. But most mammals have solid and heavy bones, which would make flying tough.

To solve this problem, bats have evolved strong and heavy bones near their shoulders, where they need more support. Theyve also saved some weight by developing lighter and weaker bones near the tips of their wings. The result is light but strong and very flexible wings.

In Western Europe homelessness has quietly been climbing to levels not seen since the end of World War II. According to the European Federation of National Organizations Working with the Homeless (FEANTSA), at least 3 million Western Europeans are homeless this winter—and between one-fifth and one-third of them are members of homeless families. Think homelessness is an American problem? Think again. As a percentage of population, its as bad in Europe as it is in the US, where there are an estimation (估计) of 2 million homeless people.

One of the fastest-growing parts of Europes homeless population is families. After all, Europe sees itself as kinder, gentler and more socially responsible than the US, with an extensive, expensive social safety net thats designed to protect the most helpless sections of the populace (平民). But that might just be the point: its easier to be homeless in Europe, where even the down-and-out get social-welfare checks.

Whats even more scary is that 3 million is almost certainly an underestimate: most European countries simply dont know where to look or how to count the homeless. Government data are confusing and unreliable (不可靠的). Austria and Spain have no official statistics at all. Germany, France, Italy and the UK have what are best described as estimates, many of them regarded by organizations that work with the homeless. INSEE, Frances national statistics agency, admits that its official count of 86,500 is only based on the number of adults that went at least once to a soup kitchen or an accommodation service. FEANTSA estimates that the real number of French homeless is closer to 200,000, but many aid organizations claim that even this figure is too low. The British government claims there are just 596 rough sleepers across the country, but those who work in Londons shelters say there are more than 1,000 in the capital alone.

4. Which of the following is TRUE according to Paragraph 1?

A. There are about 3 million homeless families in Western Europe at present.

B. Homelessness percentage in Western Europe is smaller than that in the US.

C. Western Europe homelessness has got to the highest point in the past 70 years.

D. Homelessness is no longer an American problem but a Western European one.

5. What can be the cause of more and more European families becoming homeless?

A. Europe has become much poorer than the US.

B. Europe shows too much pity on poor people.

C. Europe has a larger population than the US.

D. Europe is too proud of its social safety net.

6. It can be inferred from the passage that ＿＿＿ .

A. its easy to find out how many people are homeless in western countries

B. there are no homelessness problems in countries like Austria and Spain

C. there are more homeless people in France than in other European countries

D. not all the data that are collected by the European governments are reliable

7. How does the author feel about the situation in Europe?

A. Interested. B. Cheerful.

C. Worried. D. Easy.

It is now possible to watch live sports on television on any day of the week, and the current amount of reporting will undoubtedly increase further in years to come. This is certainly having an influence on the live sports events themselves, and there are both benefits and shortcomings to this.

Why has there been such growth in televised sport? For one thing, with digital broadcasting, there are now many more TV channels than there were even ten years ago. Moreover, sport has become an important form of entertainment, appealing to both men and women.

What are the benefits of this state of affairs? One obvious advantage to the profession is the addition of money provided by television companies. Large football clubs benefit financially from TV income and the top players can command very large salaries. Less popular sports also receive money that can be used in training and awareness-raising. Whats more, there is a health benefit to some of the population, because through televised sport, more people have become interested in actually playing sport.

However, there will be some disadvantages if so much sport is on television. Considering football again, many small clubs have suffered financial losses recently, as they cannot compete with the large ones. There has been a general falling in ticket sales, especially among smaller clubs. Fewer people attend live matches nowadays, preferring to watch from the comfort of their living room. And ticket prices have risen greatly.

To sum up, while televised sport has created many chances and benefited certain people and clubs very much, it has also been responsible for changing the nature of live sports events forever.
