Ancestors of flightless birds may have   40   their ability to fly because they had no regular predators (捕食者) or did not need to fly to find food. Rather than fly, some of these birds developed other   41  to catch food and avoid enemies. Two examples of   42  birds are penguins and ostriches.
43  birds that fly, penguins do not have wide wings or large feathers. In order to catch the fish they feed on, penguins use their powerful wings to swim   44 .

Driving in a foreign country is always different in at least some ways from driving in your own country. Here are some general points regarding driving in New Zealand.
l Visitors wishing to drive in New Zealand do not require an international driver’s license but are required to carry their local driver’s license whenever driving.
l Vehicles drive on the left-hand side of the road as they do in Britain, Australia, and Japan. Most rental vehicles will have a sticker reminding you of this important fact.
l When the traffic light is red, you must stop. There is no left turn rule as in North America.
l New Zealand road rules follow international standards but please note that in New Zealand vehicles turning left must give way to traffic turning right.
l In general, if you are turning left (where there are give-way signs or no signs), give way to vehicles that not turning. In all other situations, give way to vehicles crossing or coming from your right.
l Seat belts must be worn at all times while driving in New Zealand. This stands for the driver and passengers. The driver is responsible for ensuring all passengers are wearing their seatbelts.
l Do not drink alcohol before driving in New Zealand—drinking and driving laws are strictly enforced.
l Speed limits are in kilometres per hour (kph), not miles per hour (mph).
Speed conversion: 1 kph equals 0.621 mph; 1 mph equals 1.61 kph.
l The speed limit on the open road is 100km/h. In towns and cities the speed limit is 50km/h. Be sure to obey all school crossing speed reductions as speed cameras operate regularly throughout New Zealand.

More than two million people in Europe now have fiber broadband（光纤宽带）direct to their home, suggests a survey. The latest 1. on superfast broadband delivered by fiber to the home (FTTH) show 18% growth over the last survey compiled in late 2008.

The continued growth suggests that the 2. economic decline has not hit plans to build fiber networks. Sweden 3. the list of nations applying the technology, with 10.9% of its broadband customers using fiber. Karel Helsen, president of Europe’s Fiber-To-The-Home Council, said the growth matched predictions that were 4. when the credit crisis started to make itself felt. “The numbers in 2009 are in line with the latest forecasts,” said Mr. Helsen.

By 2013, the FTTH Council expects that 13 million people across 35 European nations will have their broadband delivered by fiber. Such services would start at a speed of 100 megabits per second (mbps), said Mr. Helsen. Around Europe more than 233 projects were underway to lay the fibers that would 5. homes or buildings to the net, said Mr. Helsen. Many of those, he said, were being operated by local governments or smaller net firms. Local governments were interested in FTTH because of the economic and social 6. it brought in its wake, said Mr. Helsen.

The low delay in high-speed fiber networks made 7. new uses of broadband, he said. “No delay is very important,” he said, “specifically if you talk about 8. that are time-dependent such as personal communications, conference calls or video calls where delays cause a lot of trouble.” While early FTTH services were 9. in cities, said Mr. Helsen, many more were reaching out to rural areas for e-health and e-learning projects.

A 33-year-old financial analyst in California recently quit his job to devote himself to an unpaid job teaching math on the Internet, and his lessons are reaching almost 100,000 people a month. Salman Khan’s voice is heard every day on the net --- by tens of thousands of students around the world who are hungry for help learning math. He has posted 1,200 lessons on YouTube ... lessons that appear on an electronic blackboard, which range from basic addition to advanced mathematics for science and finance. And they are free.

Khan lives in Silicon Valley, with his wife, a doctor, and their new baby. He got the idea for his “Khan Academy” four years ago, when he taught a young cousin how to convert kilograms to grams. With Khan’s help, the cousin got good at math, and Khan began a new career.

Now, Khan records his lessons himself, but he never goes on camera. “It feels like my voice in their head. You’re looking at it and it feels like someone’s over your shoulder talking in your ear, as opposed to someone at the blackboard, which is distant from you,” he said.

When Springfield High School in Palo Alto, California invited Khan to speak in person --- he immediately connected to the students there.

The idea of short lessons that can be played over and over again attracted high school senior Bridget Meaney. She says she had trouble with math in the seventh grade. “I think the teachers are good, but they can’t teach at a speed that’s perfect for everyone,” she said. “I like the idea of learning something in class but then going back and pressing pause or rewind and actually getting a deeper understanding of it.”

Originally, Khan kept his lessons short because of YouTube restrictions. Now, he thinks short is better. “Education researchers now tell me that 10 minutes is how long someone can have a high level of concentration. And anything beyond that and your brain switches off,” he said.

For Khan, teaching math, science, and finance is just the beginning. He says he’s ready to expand his YouTube site to include other subjects as well.

1.What gave Khan the idea of teaching math online?

A. His success in helping his cousin learn math.

B. His discovery that many students found learning math difficult.

C. A suggestion made to him at a local high school.

D. His interest in Internet teaching.

2.Why does Khan never go on camera?

A. He’s too shy to show his face on camera.

B. It’s restricted by YouTube for education videos.

C. He wants to keep distance from the viewers.

D. He wants to create a more relaxed learning atmosphere.

3.From the passage, we know that ________.

A. Khan travels to many schools to promote his lessons

B. Khan plans to include more subjects in the future

C. Khan gives live math lessons every day for free

D. Khan set up the Khan Academy with his wife

4.Why does Bridget Meaney like Khan’s lessons?

A. Khan teaches seventh grade math better than her teacher.

B. The lessons can be watched repeatedly until fully understood.

C. She can perfectly follow the pace of Khan’s teaching.

D. She cannot concentrate when learning in class.

5.What does Khan mean by “short is better” in the 6^th paragraph?

A. Keeping the lessons short can ensure better concentration.

B. YouTube recommends short lessons for its site.

C. Short lessons encourage students to return to the website.

D. Students enjoy short mathematics lessons more.
