Most children, even the youngest of children, are delighted to be around cats and dogs. But these pets carry plenty of germs and allergens（过敏原）, prompting researchers to ask: Are cats and dogs really safe for children？
A study finds that, contrary to many parents’ fears, owning cats or dogs does not increase a child’s risk of developing allergies, and in fact, may actually protect them. The study’s lead author, Dr. Dennic Ownby of the Medical College of Georgia, says that even he was “very surprised” by the results. Ownby and colleagues followed more than 470 children from birth to age 6 or 7, comparing those exposed to cats and dogs during their first year of life to those who were not.
By using skin-prick(刺) tests for detecting common allergies, the researchers found that, contrary to what many doctors had been taught for years, children who had lived with a pet were not at greater risk.
Even more remarkable, children who had two or more dogs or cats had an even greater reduction, up to 77 percent, in risk of allergies. Researchers suggest this protective effect may be the result of early exposure to lots of bacteria that are carried by dogs and cats. Exposing young children to these bacteria helps" exercise" their immune systems early in life so that they're better able to resist allergic diseases later.
There's something very important in that first year of life when the immune system is developing that we can retrain it away from an allergic response, said Dr. William Davis.
And while researchers are not encouraging parents to buy dogs or cats just to reduce a child’s allergy risk, they say if a family already has one or more animals, there's no need to get rid of them. Why do the researchers feel “very surprised” by the results of the study?
| A．Because the results are contrary to their expectation． |
| B．Because so many children are playing with cats and dogs． |
| C．Because parents are so much worried about their children． |
| D．Because children with animals may develop allergies easily． |
Compared with children who have pets，those who haven’t ______.
| A．will lose the chance to develop immune system |
| B．may suffer allergic diseases more often |
| C．will reduce the harm from bacteria |
| D．can keep doctors away |
It can be inferred from the passage that ______．
| A．pets are ill-treated by their owners |
| B．less families would like to own cats and dogs |
| C．keeping pets is a good way to keep children healthy |
| D．the results of the study can make families with pets feel at ease |
The underlined word “it” in the fifth paragraph refers to________.
| A．the early life | B．an allergic disease |
| C．immune system | D．something important |
What may be the best title of the passage?
| A．How to protect your kids from allergies |
| B．Your pets may be helping your kids |
| C．Bacteria do good to your kids |
| D．Advantages of owning pets |
Coming from the Bronx, Jennifer Lopez knew from an early age it would be tough to achieve her dream. In an interview in 2002 she remembered, “I had such a will in me. I had such a passion in me. I could overcome my situation. But a lot of people will get beaten down and be held back by that.” Lopez was not beaten by her situation. She worked hard dancing, singing, and acting in theaters and her hard work paid off with small roles in television and films.
Lopez’s big breakthrough came in 1996 when she played the main role in the movie Selena. For this movie, Lopez got paid $1 million and became the highest paid Latin actress of all time. Since then, she has had starring roles in several successful movies, including Out of Slight(1998) with George Clooney.
Then, Lopez turned her attention toward music. In 1999, she released first album, On the 6. Two songs from the album, “If You Had My Love” and “Waiting for Tonight,” both reached number one on the Billboard music cha
rts. The album sold more than three million copies around the world.
After starring in The Cell (2000), Lopez released her 
second album, J. Lo, in 2001. The album went straight to the top of the Billboard chart. At the same time that her album came out, Lopez’s new movie, The Wedding Planner, opened in theaters. It became the number one movie at the box office. This meant that Lopez was the first entertainer to ever have a number one album and a number one movie at the same time! Like her first album, J. Lo went tripe-platinum.
But her entertainment career was not the only thing Lopez focused on that year. 2001 was also the year Lopez started her own line of clothing, called J.Lo, and she married Cris Judd, a dancer who performed in her videos. The marriage did not last long, and Lopez and Judd divorced nine months later.
In 2002, Lopez starred in the films Enough and Maid in Manhattan. Maid in Manhattan became Lopez’s biggest movie yet, earning $19 million during its first weekend in theaters. Lopez also put her third album, This Is Me… Then, and the single “Jenny from the Block” hit number one for a week. To go with her line of clothing, Lopez introduced her own perfume.
In an interview, Lopez was asked if she planned to do more acting, singing, designing, or something new. She answered, “Yes, yes, yes, and yes! All of those things. I love making music, I love doing movies and all the other things. I think that everyone should do everything that they have a passion for.”What is the main idea of the passage?

Malaria, the world’s most widespread parasitic (寄生虫引起的)disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can’t) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect. They can also attach themselves to blood vessels in the brain. If it doesn’t kill you, malaria can happen again and again for years. The disease is passed on to humans by female mosquitoes infected with one of four species of a parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply a
nd are very expensive. If these drugs should fail, nobody knows what would come next. According to paragraph 1, many people don’t seek care because ________.
| A．they are too poor |
| B．it is unusual to seek care |
| C．they can remain unaffected for long |
| D．there are too many people suffering from the disease |
People suffering from malaria ________.
| A．have to kill female mosquitoes | B．have ability to defend parasites |
| C．have their red blood cells infected | D．have sudden fever, followed by chills |
Which of the following may be the reason for the wide spread of the disease?
| A．Its resistance to global warming. |
| B．Its ability to pass on the virus frequently. |
C．Its outbreaks in citi es with large populations. |
| D．Its ability to defend itself and resist new drugs. |
It can be inferred from the passage that ________.
| A．no drugs have been found to treat the disease |
| B．the alternative treatment is not easily available to most people |
| C．malaria has developed its ability to resist parasites |
| D．nobody knows what will be the drug to treat the disease |
BUKHANNON, West Virginia—Two rescue teams slowly moved along a two-mile path on Monday night to the site of a coal mine explosion that trapped 13 miners, who had not been heard from since the early morning accident．
Meanwhile, at a nearby church, more than 250 family members and friends gathered, waiting for updates（最新报道）on the rescuers’ progress．
The miners were trapped at about 6:30 and many families weren’t informed of the accident until about 10 a．m-more than three hours after it happened．“It’s very upsetting, but you’ve got to be patient, I guess,” said John Helms, whose brother, Terry, was trapped in the mine．
The trapped miners were about 260 feet underground and about 10,000 feet from the Sago Mine’s entrance, said
Roger Nicholson, general counsel from International Coal Group．
At a late night news conference, Nicholson said one team had advanced about 4, 800 feet in the four hours since entering the mine just before 6 p．m．Another team entered the mine about 30 minutes later．
He said the crew was very experienced, with some members having worked underground for 30 to 35 years．The miners were equipped with about one hour of breathable oxygen each．The company has not released the names of the miners．
The teams test the air about every 500 feet, and have to disconnect （remove
） the power to the phones they use to communicate with the surface before doing that．“ We don’t want to be energizing anything if it’s in an atmosphere with burnable gases,” Kips said．
The cause of the explosion was not immediately known．High levels of carbon monoxide were discovered shortly after the explosion, which delayed rescue efforts, but those levels have since subsided（减退）, authorities said．According to the passage, we can infer that ________．
| A．all the miners who were trapped underground were still alive |
| B．communication with the trapped miners was cut off |
| C．the two rescue teams entered the mine at the same time |
| D．the rescue started as soon as the accident happened |
If the first team advanced at an average speed, they could dig about _______ per hour．
| A．1,000 feet | B．2,400 feet | C．1,200feet | D．4,800feet |
Where can the passage be seen?
| A．In a magazine． | B．In a newspaper． |
| C．In a science book．． | D．On an advertisement． |
Which of the following shows the position where
the miners were trapped?
For a 400-year-old art form, opera had a bad fame: overweight actresses singing the words which were hard to understand in one of those romance languages you were supposed to learn in high school. And with tickets costing as much as $145 a performance, opera goers also had a certain appearance in people's mind: rich, well-dressed and old.
But now opera companies around the country are loosening their ties and kicking off their shoes in an attempt to keep opera alive and take it to a younger and not so wealthy audience.
Opera producers have found that to attract this crowd, they need to make the opera closer to common people. Because young people don't or won't come to the opera, companies are bringing the opera to them, giving performances in such unusual places as parks, libraries and public schools.
The Houston Grand Opera's choice is the public library, where it performs “mobile operas” shortened versions(剧本) of child-friendly operas. This summer's production is Hansel ＆ Gretel. By performing smaller versions of large productions, producers are able to make people interested while keeping costs at a reasonable level. The San Francisco Opera, which will be celebrating its 75th anniversary this year, is staging Cinderella free of charge, keeping costs down by employing students from its Young Artists' Training Program. Which is the main idea of this passage？
| A． Opera is famous for its long history. |
| B． Opera is only performed for rich people. |
| C． Opera companies are trying to keep opera alive. |
| D． Young people are not interested in opera. |
The underlined phrase in the second paragraph means ______.
| A． breaking up the old rules | B． changing the dresses |
| C． making the audience at ease | D．advertising themselves |
Opera companies prefer to perform short versions because ______ .
| A． they can be performed in public libraries |
| B． short versions are easy to perform |
| C． it is hard to find long versions |
| D． they can make more people come to opera |
The San Francisco Opera employs students in order to ______.
| A． celebrate its 75th anniversary | B． reduce the cost |
| C． attract young people | D． make Cinderella popular |
