U.S. airlines are seeing a major interruption because of hundreds of flights canceled due to the ash cloud from the Icelandic volcano, but European flight companies will face the biggest losses.
The airline business has been tough: The decline dramatically slowed traffic; February heavy snow forced U.S. airlines to cancel thousands of flights; and now the ashes from the volcano stopped all traffic in and out of northern Europe for days.
"For U.S. flight companies, it'll be a relatively short-term hit," said Michael Boyd, president of Boyd Group International, an aviation (航空学) consulting firm. "We think right now they're down about $80 million in terms of lost income, and they're down domestically about 80,000 passengers that would have been flying domestically but aren't because they can't get here."
Delta announced that volcano-related interruption grounded about 400 flights until Monday at a cost of $20 million in lost revenues. But compare that to the recent snowstorms, when the airline canceled 7,000 flights and lost $65 million in revenue.
The disruption has created uncertainty for customers, but analysts say U.S. airlines won't face as many costs as you might think. They are not flying in extra planes to handle the passengers in trouble because, airline analyst Robert Mann said, companies simply don't have them.
"Airlines run a very lean operation now," Mann said. "So, since there are no spare aircraft or crews, the airlines will attempt to maximize loads on every one of their aircraft that do fly. But it may take days, or in some cases a week or so, to get some of these customers to where they want to go."

B. All the customers are sure to be sent to their destinations in time.
C. The U.S. and U.K. airlines suffered the same losses in the natural disasters.
D. The volcano eruption reduced the traffic to and from northern Europe.

A. the troubles that the airlines will face after the ash cloud disappears
B. the measures that the airlines will take to maximize their profit
C. the present situation of the airlines and their plan to deliver the passengers
D. the reasons why the airlines run a fine operation
49. Why will it take a long time for airlines to send the passengers to their different destinations?
A. Because the passengers enjoy staying in airports to talk with one another.
B. Because the airlines don’t have spare planes or employees to serve.
C. Because the airlines don't have enough financial support after the disaster.
D. Because the passengers are asking for full refund from the airlines.

For most pregnant women, exercise is the last thing on their minds. After all, keeping slim while you’re expecting isn’t exactly the top priority— rather, it’s making sure your baby gets enough nutrients to grow. But in a small new study, researchers at the University of Auckland in New Zealand report that a mother’s regular aerobic exercise may be good for a growing fetus’ health — and may even help a baby get a healthier start in life.
The finding is a bit surprising, because exercise is known to lower the risk of insulin resistance（胰岛素抵抗），a condition eventually leading to diabetes（糖尿病）. Although insulin resistance is a detriment in healthy adults, it turns out to be helpful for proper fetal（胎儿）development. In pregnant women, this condition means nutrients get shunted to the growing baby.
The question is: could a mother’s exercise put her developing baby’s food supply at risk? Past studies looking at the effect of exercise on birth weight have been inconclusive, and none have really investigated the influence of exercise on the mother’s sensitivity to insulin. So the University of Auckland’s Dr. Paul Hoffman and his team decided to study 84 first-time mothers, who were of normal weight on average, and track any effects aerobic exercise(有氧运动) might have on their insulin sensitivity and, ultimately, on their babies’ birth weight. Researchers asked some women to exercise on a stationary bicycle for at least 40 minutes per session, up to five times each week, starting in the 20th week of pregnancy; the other women were not specifically asked to exercise. When the two groups and their babies were compared, the team found that women who bicycled regularly gave birth to babies who were on average 150g lighter than those born to the non-exercising mothers. In both groups, however, the babies were of healthy weight, and there was no difference in the mothers’ weights.
Generally speaking, babies on the lower end of the normal weight range are considered healthier and less prone to developing diabetes and obesity than heavier ones, so this was an encouraging result. Even more reassuring was that regular exercise did not seem to affect the flow of nutrients to the growing babies in the womb.
41. According to the new study, a pregnant woman’s regular exercise may _______.
A. bring benefits to a baby’s growth
B. lower the risk of insulin resistance
C. put her baby’s food supply at risk

B. To find out what aerobic exercise can benefit a baby’s growth.
C. To make sure of the effects exercise may have on babies’ birth weight
D. To compare the differences between mothers who exercise and who don’t

Having finished her homework, Ma Li wants some music for relaxation. As usual, she starts her computer and goes to Baidu.com to download music files. But this time she is surprised when an announcement about protecting songs’ copyright bursts onto the screen. The age of free music and movie downloads may have come to an end as Web companies like Baidu are accused of pirating copyright. Lawsuits（诉讼） have been filed against four websites offering free downloads. In September 2005, a Beijing court ordered Baidu to pay recording company Shanghai Push compensation(赔偿)for their losses. Baidu was also told to block the links to the pirated music on the website. This caused a heated discussion on Interact file sharing.
“Baidu’s defeat in the lawsuit shows it is not right to get copyrighted songs without paying. Downloaders may face lawsuits or fines,” said an official.
Like many teens, Huang Ruoru, an 18-year-old girl from Puning in Guangdong Province, doesn’t think that getting music from websites is wrong. She always shares her favourite songs downloaded from Baidu with her friends. When told about the lawsuit, she began to feel a little guilty about obtaining others’ work without paying.
However, other teenagers have different ideas. Wang Yafei, a Senior 2 girl from Jinan, Shandong Province pointed out that file sharing is a good way to promote pop singers. “If I download a song and really like it, I will buy the CD,” she said. “So what the recording companies really should concentrate on is improving their music, rather than pursuing file-sharers.”
77. Which of the following best describes the passage?
A. Downloading material can be illegal. B. It’s good to get free music on the Internet.
C. Music on the Internet is of better quality. D. Baidu is a popular web company.
78. The four web companies were put to court because _________.
A. they got copyrighted songs without paying
B. they downloaded copyrighted music for people
C. they offer free music on line
D. they make copyrighted files for free downloads
79. How do some of the teenagers feel while downloading free music after the lawsuit?
A. A bit guilty. B. Awfully sorry. C. A little sad. D. Extremely angry.
80. It can be inferred from the text that _________.
A. Web companies are still ignoring the copyright laws.
B. Teenagers haven’t got money to buy CDs.
C. Teenagers are probably still downloading free music.
D. Teenagers prefer CDs with copyright to pirated music.

Schools across the country are turning green. So-called green schools are built from recycled and environmentally friendly materials. They are designed to use less energy than traditional school buildings. In the next few years, Southern California alone plans to open 150 green schools. Studies have shown that there are good reasons to go green, including good air quality that cuts down on asthma(哮喘)attacks and airborne germs that can cause illnesses. Students learn better in classrooms that have natural light and ideal temperatures. Green schools have lower energy bills. Go On, Get Green
Here’s how to save energy and help the environment.
Light Savers
Turn off the lights in a room when it is not in use. This bright idea can produce big savings on energy costs. Some schools use sensors that automatically shut off the lights when there is no motion in a room.
Heat Smart
Your school’s thermostat(温度调节器)should be set to 78℃in warm weather and 68℃in cooler weather. The temperature can be even farther from the comfort zone at night and on weekends, when no one is using the school building.
Reuse, Recycle
Reuse paper, cans, bottles and batteries. Use both sides of notebook paper. Carry a lunch box rather than a paper bag. Recycle whatever you can reuse.
Don’t Drip(滴水)
Leaky taps can waste large amounts of water. A small, steady flow can add up to hundreds of gallons a year. Report drips if you see them.
73. What is the best title for the passage?
A. Green Schools. B. Reusing and Recycling. C. Light Savers. D. No Dripping.
74. Some schools are called green schools because ______.
A. they are built from new materials B. they are painted green
C. there are more trees in these schools D. they are built from recycled materials
75. All of the following are advantages of a green school EXCEPT __________.
A. the air quality of the school is great
B. the temperature is comfortable
C. the school has lower energy bills than a traditional school
D. it is more beautiful than a traditional school
76. In a green school, students will ________.
A. use both sides of their notebook paper B. not use lights at all
C. use paper bags to carry food D. get sick more easily

Banks view online banking as a powerful “value-added” tool to attract and keep new customers while helping to eliminate costly paper handling or teller（出纳员）interactions in an increasingly competitive banking environment .
Today , most large national banks , many local banks and credit unions offer some form of online banking , variously known as PC banking , home banking , electronic banking or Internet banking . Online banks are sometimes referred to as “brick-to-click” banks , both to tell them from “brick-to-mortar” banks that haven’t yet offered online banking , as well as from “virtual”（虚拟）banks that have no physical branches or tellers whatsoever .
The challenge（挑战）for the banking industry has been to design this new service channel in such a way that its customers will readily learn to use and trust it . Most of the large banks can now offer fully safe ,fully functional （功能的）online banking for free or for a small cost . As more banks succeed online and more customers use their sites , fully functional online banking will likely become as commonplace as automated teller machines (ATM).
Online banking has a lot of advantages . Unlike your corner bank , online banking sites never close; they’re at hand 24 hours a day , seven days a week , and they’re a mouse click away . If you’re out of state or even out of the country when a money problem appears , you can log on instantly to your online bank and take care of business . Online bank sites generally carry out and confirm （确认）deals at or quicker than ATM processing speeds . Many online banking sites now offer fashionable tools to help you manage all of your valuable items more effectively .
69．The word “eliminate” in the first paragraph probably means “___________”.
A．keep B．remove C．reduce D．improve
70．What is the challenge for the banking industry according to the text ?
A．To make online banking attractive . B．To open new services all over the world .
C．To offer online banking for free . D．To take care of business 24 hours a day .
71．From the text we can conclude that__________ .
A．“brick-to-click” banks are in fact another kind of physical banks
B．the function of a “brick-to-click” bank is as common as that of an ATM
C．a “ brick-to-mortar” bank is no better than a virtual one
D．customers can deal with their banking by a mouse click
72．What would be the best title for this text ?
A．Banking of Various Forms B．Improvement of Banking Industry
C．Development of Online Banking D．Functions of the “Brick-to-Click” Bank
