For Americans, a mosquito bite is an itchy bother. But for many in Africa, a tiny bite can be deadly. One million people die each year of malaria, a disease spread by infected mosquitoes. Most of these people live in Africa, and are under age 5.
Malaria can be prevented and treated. However, many African nations don't have the funds to fight it. Nothing but Nets (NBN) hopes to change that. The United Nations Foundation created the campaign in 2006. The aim is to prevent malaria by covering sleeping areas with nets. Hanging bed nets treated with insecticide(杀虫剂) is the simplest way to stop mosquitoes from biting at night. The chemicals last four to five years. For $10, anyone can send a net to Africa and help save a life.
So far, NBN has raised $19 million and delivered 700,000 nets to seven countries. Families are taught how to use the nets. Kids also get vaccines (疫苗)and vitamins. "Women line up for miles to get the medicine for their kids," says NBN director Elizabeth McKee Gore. "They understand the importance."
So do kids in this country. "They get so excited thinking of ways to raise money," says NBN spokesperson and basketball star Ruth Riley.
NBN's biggest fund-raiser is Katherine Commale, 7. She's been spreading the information about bed nets for the past two years. To show how they work, she and her brother made a video. "We teach that bed nets can save lives," she said.
Katherine has raised $42,000 for NBN. "She just wants those who need a net to have one," says her mom, Lynda. "It's pretty simple to her." To find out how you can help, visit nothingbutnets.net.
1.We know from the passage that NBN is in fact _________.

Ants are troublesome, best known for itchy bites and ruining picnics. But, a new species of crazy ant is taking over Texas. In some ways they appear to be worse than fire ants and there's no good way to stop them* These ants move fast and are plentiful in some areas.
The crazy ants first sprang in Pearland in 2002 and have been becoming more and more of a problem ever since.“An invasion of these can be so extreme that it's hard to call it just a nuisance," University of Texas entomologist Edward LeBrun told The Austin American-tatesman. “The ants have been known to crawl into and ruin televisions, appliances and other electronic devices. No one is entirely sure why," He said.
David Oi , a research entomologist at the Department of Agriculture, told The New York Times in 2013, the strange idea that the ants are actually attracted to the electricity itself can't be ruled out.
The crazy ants or Raspberry ants-yep, that's actually what they are called-are found in 23 Texas counties. The ants have very little venom(毒液), but do cause a slight sting when they bite. Mostly, though, they're a hazard to electrical equipment.
They are a relatively new species in the region and little is known about how to control or kill the population. And, unfortunately, there doesn't seem to be much that can be done about them right now. So, for the moment, the best advice is not to stay close to ant piles and groups. and hope that none make it inside to crawl around the electronics.
1.What do the ants do in Texas?
A. Bite some people. B. Damage local crops.
C. Destroy appliances. D. Pollute environment.
2.The underlined word "nuisance" in Paragraph 2 is closest in meaning to " ”.
A. story B. problem
C. visit D. failure
3.When meeting with ant piles, we'd better .
A. kill them all B. control them
C. drive them away D. stay away from them
4.What can we know from the text ?
A. The crazy ants first. appeared in Texas in 2013.
B. The crazy ants cause huge loss to the people in Texas.
C. The government is taking measures to deal with the ant.
D. David Oi is sure why the ants ruin electronic devices.

A bite from a tsetse fly (采采蝇) is an extremely unpleasant experience. It is not like a mosquito, which can put its thin mouthpart directly into your blood, often without you noticing. In contrast, the tsetse fly’s mouth has tiny saws on it that saw into your skin on its way to suck out your blood.
To make matters worse, several species of tsetse fly can transmit diseases. One of the most dangerous is a parasite that causes "sleeping sickness", or "human African trypanosomiasis"to give it its official name. Without treatment, an infection is usually fatal.
Like so many tropical diseases, sleeping sickness has often been neglected by medical researchers. However, researchers have long endeavored to understand how it avoids our bodies’ defence mechanisms. Some of their insights could now help us eliminate sleeping sickness altogether.
There are two closely-related single-celled parasites that cause this deathly sleep: Trypanosoma brucei rhodesiense and T. b. gambiense. The latter is far more common: it is responsible for up to 95% of cases, mostly in western Africa. It takes several years to kill a person, while T. brucei rhodesiense can cause death within months. There are still other forms that infect livestock.
After the initial bite, sleeping sickness symptoms often start with a fever, headaches and aching muscles. As the illness goes on, those infected become increasingly tired, which is where it gets its name. Personality changes, severe confusion and poor coordination can also happen.
While medication does help, some treatments are toxic and can themselves be deadly, especially if they are given after the disease has reached the brain.
It is worth noting that sleeping sickness is no longer as deadly as it once was. In the early 20th Century several hundred thousand people were infected each year. By the 1960s the disease was considered "under control" and had reached very low numbers, making its spread more difficult. But in the 1970s there was another major epidemic, which took 20 years to control.
Since then, better screening programmes and earlier interventions have reduced the number of cases dramatically. In 2009 there were fewer than 10,000 cases for the first time since records began, and in 2015 this figure dropped to fewer than 3,000, according to the latest figures from the World Health Organisation. The WHO hopes the disease will be completely eliminated by 2020.
While this decline looks positive, there may be many more cases that go unreported in rural Africa. To eliminate the disease completely, infections have to be closely monitored.
More problematically, a series of new studies have shown that the parasite is more complicated than previously believed.
Sleeping sickness has always been considered —— and diagnosed —— as a blood disease, because T. brucei parasites can readily be detected in the blood of its victims.
1.A tsetse fly is different from a mosquito in that________.
A. it can put its thin mouthpart directly into your blood
B. all species of tsetse fly can transmit diseases
C. it can spread a parasite that causes "sleeping sickness"
D. its mouth has larger saws than those on a mosquito
2.What can be learned about "sleeping sickness" according to the text ?
A. It is formally called"human American trypanosomiasis".
B. If left untreated, it can possibly be deadly.
C. It remains as deadly as it used to be.
D. It usually draws attention from medical researchers.
3.What is implied in the last three paragraphs ?
A. "Sleeping sickness" will be completely eliminated by 2020.
B. The parasite causing "sleeping sickness" is easy to detect now.
C. T. brucei parasites can only be detected in the blood of its victims.
D. Data about "sleeping sickness"cases may not be so accurate.
4.What would be the best title of this passage ?
A. A mosquito that can carry deadly diseases.
B. A bite from this fly puts you into a deadly sleep.
C. Symptoms that are characteristic of "sleeping sickness".
D. How to control deadly"sleeping sickness" from a tsetse fly.

They still bite, but new research shows lab-grown mosquitoes are fighting dengue fever — a dangerous disease that they normally would spread. Dengue infections appear to be dropping fast in communities in Indonesia, Vietnam, Brazil and Australia that are filled with the specially grown mosquitoes.
Researchers first injected (注射)mosquito eggs with Wolbachia bacteria that's common in insects and harmless to people in a lab. Infected females then pass the bacteria on through their eggs. Releasing enough Wolbachia carriers, both the females that bite and the males that don't, allows mating(交配)to spread the bacteria through a local mosquito population.
Rather than using chemicals to wipe out pests, “this is really about transforming the mosquito," said Cameron Simmons of the nonprofit World Mosquito Program, which is conducting the research.
The first success came from Australia. Mosquitoes carrying Wolbachia were released in parts of North Queensland starting in 2011, and gradually spread through the local mosquito population. Dengue is spread when a mosquito bites someone who is infected, and then bites another person, but somehow Wolbachia blocks that — and local spread has nearly disappeared in those North Queensland Communities, Simmons said.
The studies are continuing in other countries. But the findings, presented at a meeting of the American Society for Tropical Medicine and Hygiene, suggest it's possible to turn at least some mosquitoes from a public health threat into annoying biters.
The work marks “exciting progress," said Michigan State University professor Zhiyong Xi, who wasn't involved with the project but has long studied how Wolbachia can turn mosquitoes against themselves.
More research is needed, specialists cautioned. "The results are pretty exciting — strong levels of reductions — but there clearly are going to be things to be learned from the areas where the reductions are not as great," said Penn State University professor Elizabeth McGraw.
1.What can we learn about the lab-grown mosquitoes?
A.They lose the ability to bite people.
B.They become harmful to human beings.
C.They carry dangerous Wolbachia bacteria.
D.They spread Wolbachia bacteria by mating.
2.What does the underlined word "that" refer to in Paragraph 4?
A.The bite from a mosquito. B.The local community.
C.The spread of Dengue. D.The infected person.
3.What do the last two paragraphs suggest?
A.This research proves a complete success.
B.Scientists agree on this research.
C.There is still room for improvement.
D.Mosquitoes turn themselves against harmful ones.
4.What is the best title for the text?
A.Bacteria- infected Mosquitoes Bite Deadly Dengue.
B.Transform Mosquitoes into Annoying Biters
C.Fight against Mosquitoes with Wolbachia
D.Harmless Mosquitoes Are on Their Way

高三英语书面表达中等难度题查看答案及解析
Some people sit outside for hours without getting bitten by mosquitoes, but it always seems like you’re being eaten alive within minutes of stepping outdoors.
If this is you, you’re not alone. According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoes. What about these people makes mosquitoes’ mouths water?
A popular myth claims that mosquitoes prefer certain blood types, but the fact is that they simply can’t tell what your blood type is from a faraway place. Jonathon Day, a professor of medical entomology (昆虫学) at the University of Florida in the US, told NBC it’s not complicated. “The two most important reasons a mosquito is attracted to you have to do with sight and smell.”
Mosquitoes are especially active in the late afternoon. While flying along, they use their sense of smell to find possible targets. They find victims (攻击对象) by smelling the carbon dioxide (CO2) breathed out by humans and animals. That’s why you commonly find them in crowded streets and parks.
Joop van Loon, an entomologist at Wageningen University in the Netherlands, told Live Science, “Mosquitoes start orienting (使......朝向) themselves to carbon dioxide and keep flying upwind as they sense higher concentrations (浓度).”
As a result, people who simply exhale (呼出) more of the gas over time – generally, larger people – have been shown to attract more mosquitoes than others. “This is why kids don’t get bitten as much ... as adults,” US professor Ted Rosen told Science Alert.
This love for CO2 can also put pregnant women at increased risk for mosquito bites, as they tend to exhale 21 percent more CO2 than people of the same age and size who aren’t pregnant.
In addition to carbon dioxide, the color of the clothes you wear also plays a role in attracting mosquitoes.
According to Live Science, mosquitoes can lock onto targets from up to 50 meters away. At this distance, what we wear has a huge effect. Due to their vision (视觉), people wearing dark colors are more likely to become targets.
Being bitten by mosquitoes is annoying, but don’t worry. Some simple tips can help ward them off. Scientists recommend that we use insect repellent (驱虫剂) and wear light-colored clothing.
1.How do mosquitoes locate their targets, according to the article?
A.By seeking out bright clothes.
B.By identifying different blood types.
C.By sensing an increase of carbon dioxide.
D.By following bigger crowds.
2.Why are pregnant women more likely to be bitten by mosquitoes?
A.Their larger size helps mosquitoes to see them.
B.They breathe out more CO2.
C.They are more likely to sweat.
D.Their body temperatures are higher.
3.How does the article advise you to avoid mosquitoes?
A.Exercise regularly.
B.Wear light-colored clothing.
C.Keep your skin dry and clean.
D.Stay indoors in the evening.
4.What’s the article mainly about?
A.A new finding about mosquitoes.
B.How people can avoid mosquito bites.
C.A popular myth about mosquitoes.
D.Why some people are more attractive to mosquitoes than others.
