Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas. 1.

Most Americans would find it hard to imagine what life would look like without cars. 2.. The polluted air becomes poisonous and dangerous to health.

3.. That’s what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.

Another way is to take the place of the car engine by something else. 4.. Many makers believe that it will take years to develop a practical model that pleases man.

To prevent the world from being polluted by cars, we’ll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help the air clean. But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down. 5..

Although cars have led us to a better life, they have also brought us new problems.

A. Inventors are now working on steam cars as well as electric cars

B. Americans know cars very well.

Taj Mahal, Agra, India

As many as 28 different varieties of precious stones were used to decorate the outside of the Taj Mahal. Construction took around 20 years. The building, which was made from white marble from the quarries(采石场) of Rajasthan, appears pink in the morning, white in the day and golden in the moonlight.

Akashi Kaikyo Bridge, Akashi Strait, Japan

It took 10 years to construct the Akashi Kaikyo Bridge. It connects the city of Kobe, on Japan’s mainland, with Iwaya on Awaji Island. Before it opened, the only way to get between the two cities was by ferry. However, the waterway was at the mercy of severe storms and when two ferries overturned in 1955, killing 168 people, public anger convinced the government of the need for a bridge. It's the longest suspension bridge in the world, with a length of 1,991 meters.

Panama Canal, Panama

More than 4. 5 million cubic yards of concrete were used in the construction of this canal’s locks and dams. The Panama Canal is a 47-mile long waterway that connects the Atlantic and Pacific Oceans. The earth and rubble dug to make way for it was enough to bury Manhattan to a depth of four meters. A series of locks allows ships to pass through the water. Each lock door weighs 750 tons and each lock fills with 52 million gallons of water to accommodate the 15,000 ships that use the canal every year.

A good modern newspaper is an extraordinary piece of reading. It is remarkable first for what it contains: the range of news from local crime to international politics, from sports to business to fashion to science, and the range of comment and special features as well, from editorial page to feature articles and interviews to criticism of books, art, theatre, and music. A newspaper is even more remarkable for the way one reads it: never completely, never straight through, but always by jumping from here to there, in and out, glancing at one piece, reading another article all the way through, reading just a few paragraphs of the next. A good modern newspaper offers a variety to attract many different readers, but far more than any one reader is interested in. What brings this variety together in one place is its topicality(时事性) , its immediate relation to what is happening in your world and your locality now. But immediacy and the speed of production that goes with it mean also that much of what appears in a newspaper has no more than transient value. For all these reasons, no two people really read the same paper: what each person does is to put together, out of the pages of that day’s paper, his own selection and sequence, his own newspaper. For all these reasons, reading newspapers efficiently, which means getting what you want from them without missing things you need but without wasting time, demands skill and self-awareness as you modify and apply the techniques of reading.

An oral drug, named ERDRP-0519, was invented. It is specifically designed to protect people who got infected measles(麻疹) from spreading the virus to others. Like the flu, measles spreads through the air by breathing, coughing or sneezing. There is typically a time, about two weeks, between becoming infected with the virus and the beginning of symptoms like skin rash(皮疹), runny nose, heavy cough and high fever.

“This therapy application determines the desired characteristics of the drug, which are orally available, cost-effective manufacture and high stability,” Richard Klemperer, professor of Georgia State University, told reporters last Wednesday.

“With these criteria in mind, we have developed a small drug that blocks the measles virus over the past years, which is essential for copy of the virus.”

The researchers tested the drug in rats infected with canine distemper virus(犬瘟病) , which is a close relative of measles virus. They found that all of the infected rats treated with the drug survived the deadly infection, showed no clinical signs of disease and developed a strong protective immune response.

The drug could be used to treat friends, family and other social contacts of a person infected with measles virus, which have not developed symptoms yet but are at risk of having caught the disease, Klemperer said truthfully.

“The emergence of strong antiviral immunity(抗病毒免疫力) in treated animals is particularly encouraging, since it suggests that the drug may not only save an infected individual from disease but contribute to closing measles immunity gaps in a population,” Klemperer said.

The researchers emphasized the drug is not intended as a substitute for vaccination, but as an additional weapon to get rid of the measles. They planned to test the drug’s safety in larger animals, before moving into clinical trials in humans.

“If our next series of studies confirms that the human situation mirrors what we have seen in rats, then this drug may make a major contribution to getting rid of measles by preventing local outbreaks” Klemperer said.

Despite the existence of an effective vaccine, annual measles deaths worldwide have remained constant at around 150,000 since 2007. The reasons for this are the highly infectious nature of the virus, in the developing world largely due to issues of resources, and in many developed countries in particular in the European region due to parental concerns regarding vaccination safety.

1.If a boy got infected by measles virus, he might NOT show the symptom like ________.

A. runny nose B. bad cough

C. high fever D. sick stomach

2. From what Klemperer said, we know that the drug _________.

A. is only intended as a substitute for vaccination

B. can only save those infected individuals from disease

C. is cost-effective and high stability for curing measles

D. has the same effect on human as on larger animals

3.The best title of the passage is_________ .

A. the Introduction of a New Oral Drug

B. the Desired Characteristics of Drugs

C. the Common Symptoms of Getting Measles

D. the Application of Post-exposure Therapy

Many people rush into the commitment of bringing home a four-legged family member, only to find out that they are not ready for a pet.This often results in the dog being turned over to a shelter where it may not find another home.This can be avoided if potential pet owners take the time to figure out if they are truly ready for the responsibilities of pet ownership.

Being a responsible pet owner involves a financial commitment that goes beyond buying dog fooD. There are also parasite (寄生虫) prevention, boarding costs while traveling and the cost to care for the pet should it become ill or injureD. That is not to say that one must be rich in order to have a dog, but it is important to be prepared for the expenses that come with being a pet owner.

Another consideration is the time commitment.An owner away from home for 14 hours every day is not an ideal situation for a dog.A potential dog owner must also consider the time it takes to care for his or her pet, the time it takes to feed, walk, play with, bathe and clean up.Also, dogs require attention.Be prepared to spend time each day petting and playing with it.

Dogs are dogs, and will act like dogs.This includes barking, digging, having accidents in the house and, possibly, destroying some of the owner’s prized possessions, such as furniture, shoes and cell phones.If the above would cause an owner to want to get rid of the dog, then he or she is not yet ready to be a pet owner.Many wonderful pets end up in shelters simply because they acted like dogs!
