Mosquitos can infect you with Malaria, yellow fever, and dengue. All can kill you. So we spray large areas with pesticides (杀虫剂) .But this negatively affects the whole ecosystem and your health. Now there’s a new device, which claims to keep you and your loved one’s mosquito free.
The device was designed by two German engineers who were fed up with being bitten while camping. They found solutions containing ‘DEET’ — a damaging chemical which could be both harmful to us and the environment — worked best, but still only for 45 minutes maximum and that the traditional anti-pest devices didn’t work well! So, they designed the brand new type of bug killer, Moskinator.
Instead of trying to keep the mosquitos away, it actually attracts them, then catches and kills them! It lures (引诱) the flies and mosquitos near using a safe, completely harmless LED light. The flying pests (害虫) can’t resist the UV-PT light! Next to the LED light is a powerful, yet efficient reverse fan that sucks (吸) the insects through a one-way trapdoor. Once trapped in the drying basket they are dried to death by the fan a matter of 2 minutes. You can simply empty the dead bugs into the trash, without even touching them.
Does Moskinator really work in real life? We had some of our customers try it out in their homes. The results speak for themselves:
“My wife would complain she had a headache in the mornings whenever we used chemical pesticides. Now we use our Moskinator, and we wake up bite and headache free!”— Shane Maguire
“This Moskinator really works and you don’t have to worry about breathing any harmful chemicals.”— Jake Shearer

2.What is the function of the LED light?

C.It sucks pests inside. D.It dries pests to death.
3.Which of the following best describes the new device?

Researchers say public mistrust of vaccines（疫苗）is causing diseases like measles（麻疹）and yellow fever to spread. The scientists said the lower levels of trust can lead to people refusing vaccines. This, in turn, can cause diseases to spread quickly, they warmed.
But the researchers said they also found a high level of support worldwide for vaccinating children against disease.
The researchers questioned 66,000 people in 67 countries to discover their ideas on whether vaccines are important, safe and effective. The survey showed people in Southeast Asia had the highest level of trust in vaccines. Africa showed the second highest level of confidence. Europeans showed the lowest level of confidence in vaccines. In France, 41 percent of the population questioned the safety of vaccines.
Heidi Larson is with the London School of Hygiene and Tropical Medicine. She says recent media reports of problems involving vaccines have hurt public confidence in France. Larson noted that many Europeans worried about reports of possible links between hepatitis B vaccines（乙型肝炎疫苗）and the disease multiple sclerosis（多发性硬化症）. But she said scientists found no linkage between the two. Mistrust in France was also driven by public reaction to the H1N1 influenza（甲型H1N1流感）outbreak fears in 2009. The French government spent $1.4 billion on 94 million doses of the vaccine. The majority were sold or destroyed.
The findings come as a major yellow fever vaccination program has been launched in the Democratic Republic of Congo and Angola. The disease has already killed hundreds of people in the area. The World Health Organization aims to vaccinate over 15 million people in both countries. “If everyone agrees to be vaccinated, we can remove yellow fever from our country,” said Mosala Mireille, one of the doctors directing the program.

3.Mistrust of vaccines in France was driven by the following reasons except ________.
A. media reports of problems linked to vaccines
B. public reaction to the H1N1 influenza outbreak fears in 2009
C. connections between hepatitis B vaccines and the disease multiple sclerosis
D. most of the doses of the vaccine were sold or disposed of by the French government
4.Mosala Mireille’s attitude towards the yellow fever vaccination program is ________.
A. Expectant B. Skeptical
C. Critical D. Cautious

Tyler was born infected with HIV and his mother was also infected. From the very beginning of his life, he was dependent on medications (药物) to enable him to survive. When he was five, he had a tube surgically(外科手术上) inserted in a vein(静脉) in his chest. This tube was connected to a pump, which he carried in a small backpack on his back. Medications were connected to this pump and were continuously supplied through this tube to his bloodstream. At times, he also needed supplemented oxygen to support his breathing.
Tyler wasn't willing to give up one single moment of his childhood to this deadly disease. It was not unusual to find him playing and racing around his backyard, wearing his backpack and dragging his tank of oxygen behind him in his little wagon(小推车). All of us who knew Tyler were amazed at his pure joy in being alive and the energy it gave him. Tyler's mom often made jokes on him by telling him that he moved so fast she needed to dress him in red. That way, when she peered through the window to check on him playing in the yard, she could quickly spot him.
This terrible disease eventually wore him down. He grew quite ill and, unfortunately, so did his HIV-infected mother. When it became clear that he wasn't going to survive, Tyler's mom talked to him about death. She comforted him by telling Tyler that she was dying too, and that she would be with him soon in heaven.
A few days before his death, Tyler beckoned(召唤) me over to his hospital bed and whispered, "I might die soon. I'm not scared. When I die, please dress me in red. Mom promised she's coming to heaven, too. I'll be playing when she gets there, and I want to make sure she can find me."
1.Why did Tyler wear a backpack on his back when he was young?
A. Because his mother gave it to him as a gift.
B. Because he had no right to choose but to wear it.

B. Patients should be treated with respect.
C. People should have great courage to face the problems.
D. We should try our best to help those who are infected with HIV.

Bad teeth can be painful -- and worse. They can even be deadly. Infections (感染) of the gums (牙龈) and the teeth can cause bacteria (细菌) to go into the blood system. Those bacteria can increase the chance of a heart attack and worsen the effects of other diseases. And adults are not the only ones at risk.
For example, in 2007, doctors in the Washington area said a boy died when a tooth infection spread to his brain. They said it might have been prevented had he received the dental care (牙齿保健) he needed. He was twelve years old.
Experts at the National Institutes of Health say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow the growth of bacteria and acid production in the mouth.
But dentists say a baby's gums and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, only give the child water.
When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently.
The use of fluoride (氟化物) to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel (珐琅质) , the hard surface on teeth, to help prevent holes from forming.
1.Which of the following can be used as the title of the passage?
A．Concerns for Healthy Teeth of the Young
B．Causes of Teeth Problem
C．Importance of Healthy Teeth of All
D．Solutions to Teeth Problem
2.What's the main idea of paragraph 4 and 5?
A．How to develop babies' teeth. B．How to keep babies' teeth clean
C．Why to protect babies' teeth D．Why to keep babies' teeth clean
3.The passage indicates that ______.
A．Enamel is most widely used to protect teeth in the world
B．Breast milk can cure babies' bad teeth
C．Bad teeth may affect the health of adults and the young
D．Babies' teeth should be brushed once per day
4.The writer uses the boy's death as an example to show that ______.
A．not only adults but the young may suffer from teeth problem
B．the doctors should be responsible for the case
C．babies with bad teeth can easily die
D．the boy was not fed with his breast milk

Bad teeth can be painful and even be deadly. Infections of the gums(牙龈) and teeth can release bacteria into the blood system. Those bacteria can increase the chance of a heart attack or stroke and worsen the effects of other diseases. And adults are not the only ones at risk. For example, a 12yearold boy died when a tooth infection spread to his brain in 2007 in Washington. Experts said it might have been prevented had he received the dental care he needed.
Experts say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth.

The use of fluoride(氟化物) to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel(釉质), the hard surface on teeth, to help prevent holes from forming.
But young children often swallow toothpaste when they brush their teeth. The American Academy of Pediatric Dentistry notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully watched when they brush their teeth. And only a small amount of fluoridated toothpaste, the size of a pea, should be used.
Parents often wonder what effect finger sucking might have on their baby's teeth. Dental experts generally agree that this is fine early in life. Most children stop sucking their fingers by the age of four. If it continues, experts advise parents to talk to their children's dentists or doctors. Because it could interfere_with the correct development of permanent teeth.
Dentists say children should have their first dental visit at least by the time they are one year old. They say babies should be examined when their first teeth appear—usually at around six months.
1.According to the passage，what is the function of fluoride?
A．Making the surface on teeth much cleaner.
B．Protecting gums from being infected.
C．Keeping holes on teeth from forming.
D．Slowing down bacterial growth and acid production.
2.The underlined phrase “interfere with” in Para.5 probably means “________”．
A．do harm to B．account for
C．contribute to D．stand for
3.What is the purpose of the author in writing the passage?
A．To warn us of the deadly infections of gums and teeth.
B．To introduce the advantages of fluoridated toothpaste.
