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

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

3.The best title of the passage is_________ .

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!

As children begin to head back to school, there are several things that you can do to make sure that your child stays healthy and performs at their peak potential during the school year.

1．Make sure your child is up to date on their immunizations(免疫)．The summer is a good time to schedule visits to the doctor’s as your child is not in school, and the visit won’t require that your child miss school days.

2．Encourage proper nutrition．America faces childhood obesity(肥胖)．This means that the percentage of overweight children is increasing each year, and this will place your child at risk of developing a variety of diseases when they are middle age or even young adults．You can start helping your child to become healthier by offering fruits and vegetables at home instead of calorie heavy potato chips and candy.

3．Get your child involved in sports activities．Activities in high school such as track and cross-country are important for socialization for your child, as well as helping to improve their health．You can get your child interested in wholesome activities by discussing with them how you enjoyed similar activities in high school.

4．Have the birds and the bees conversation with your child．Many children become sexually active in junior school and senior high school, and the sooner you discuss sex with your child the sooner they will be prepared．Tell your child that there is always the possibility of infecting a sexual disease when two people have sex; and discuss with your child the use of condoms．The sooner you start having this embarrassing situation the better.

5．Know your child’s friends．You can do this by inviting your child to bring their friends over to your house for a pizza night, or by chatting with them when they stop by your house．If you find your child’s friend has a bad reputation, then you could consider introducing your child to a different network of people, such as through the girl/boy scouts．Forbidding your child from seeing a certain person may only lead them to rebel and become closer to that person.

6．Discuss with your child the seriousness of drug use and abuse．Your child may not realize that using drugs can have serious consequences．Your child may get the false impression that drug use is his right．Explain to a child that saying no to drugs is their right, and that anybody offering them drugs is not their friend.

7．Help your child to avoid a life long smoking addiction by discussing with them the consequences of smoking．The sad fact is that most smokers became addicted when they were in their teenage years, and are unable to quit for long periods of time and often die many years earlier due to their smoking habit which increases the risk of lung cancer, heart disease, and a variety of medical conditions．Even if you are a smoker yourself, you can discuss with your child about how damaging smoking can be on a person’s health.

8．Impress upon your child the importance of traffic rules．Tell them that it is OK to wear a seat belt in anyone’s car, because it may save their life one day．If your child rides a bicycle or a skateboard, then discuss with them the importance of always wearing a helmet．As you child becomes qualified for driver’s permit, you should discuss with them the importance of prevention from drinking and driving.

9．Be cautious about signs of depression in childhood．A surprisingly large number of children may become depressed, and a small number of teenagers and children commit suicide(自杀) each year．Realize that any signs of unusual depressed mood, angry outbursts, suicidal comments, feelings of hopelessness, and loss of enjoyment of activities with friends may be signs of depression.
