Mosquitoes have an extraordinary ability to target humans far away and fly straight to their unprotected skin. Regrettably，mosquitoes can do more than cause an itchy(发痒的）wound. Some mosquitoes spread several serious diseases，including Dengue，yellow fever and malaria.

Over one million people worldwide die from these diseases each year. New research now shows how mosquitoes choose who to bite.

Mosquitoes need blood to survive. They are attracted to human skin and breath. They smell the carbon dioxide gas，which all mammals breathe out. This gas is the main way for mosquitoes to know that a warm-blooded creature is nearby.

But mosquitoes also use their eyes and sense of touch. Michael Dickinson is a professor at the California Institute of Technology. His research shows how these small insects，with even smaller brains，use three senses to find a blood meal.

Michael Dickinson’s team used plumes—a material that rises into the air of carbon dioxide gas into a wind tunnel. They then used cameras to record the mosquitoes. The insects followed the plume.

Then，the scientists placed dark objects on the lighter colored floor and walls of the tunnel. Mr. Dickinson said，at first，the mosquitoes showed no interest in the objects at all. “What was quite striking and quite surprising is that the mosquitoes fly back and forth for hours. These are hungry females and they completely ignore the objects on the floor and wall of the tunnel. But the moment they get a hit of CO2，they change their behavior quite obviously and now would become attracted to these little visual blobs (斑点）.”

This suggested to the researchers that a mosquito’s sense of smell is more important in the search for food. Once mosquitoes catch a smell of a human or animal，they also follow visual signals.

1.What do mosquitoes mainly use to find their targets?

A. Sense of smell. B. Sense of touch.

2.The first response of the mosquitoes to the objects in the experiment is .

A. to fly to the dark ones

3.How can we avoid being attacked by mosquitoes according to the text ?

A. Don’t let them see us.

B. Use dark objects to stop them.

C. Make them fly back and forth for hours.

D. Attract them to objects full of carbon dioxide gas.

4. What can be the best title for the text?

A. How Do Mosquitoes Survive?

B. Why Do Mosquitoes Need Blood?

C. How Do Mosquitoes Choose to Bite You?

D. Why Do Mosquitoes Attack the Human Being?

Kompong Phhluk Private Tour

Depart the city for an unspoiled floating community called Kompong Phhluk which is astonishing for its stilted-house villages and flooded forest.

Stop on the way for the Rolous Market tour. This is a great chance for you to take the photos of locals selling vegetables, different fish species and other local produce.

After this market tour we’ll all have a boat trip to the floating community of Kompong Phhluk, visit an island pagoda, a school and houses standing on 8 or 10m high stilts, fish farms and learn about the village life.

Stop and have lunch in a family’s house before getting into a row boat and venturing into the flooded forest, the habitat to some famous water-bird species.

Eventually we jump back into the big boat and set off for the largest fresh water lake in SE Asia, Tonle Sap.

Bit by bit, the sand dust that fills the sky is dying down. The blue sky and the burning sun once again hang over the desert.

He is on the road, driving his beat-up yellow cab. The sides of the road are littered with damaged vehicles. Masses of smoke in the distance tell him that a war is being dragged on throughout his country.

It’s a fine day despite the choking heat. Not a breath of wind is blowing.

A group of vehicles are traveling towards him, carrying many passengers. The scene reminds him of the market days in this country when crowds of trucks transport folks to the markets; the only difference is, this time, they are not trucks, but tanks, carrying foreigners, guns in hand. He stares at them. They stare back. So they pass by one another.

“The damned war!” he whispers bitterly. Two days ago, a bomb fell on the market in front of his house, destroying nearly everything in sight. He survived by luck. He decided then and there that he would give up this cab business. This will be his final run. After this, he will leave this place together with his wife and children.

“Shala and my children, we’ll soon meet each other again, after I’m done here.” He turns his head to take a glance at a photo of his wife and children. The glass on the frame is broken, but their smiles in the picture do not fail to provide him with the only comfort that he has.

Shortly he arrives at a checkpoint. Tanks sit by the side of the road, the sight of which sends a marked coldness through his backbone. A bunch of soldiers armed to the teeth stand by. A foreign soldier signals him to stop. He calms himself down and pulls over. During the past few days, nearly no civilian（平民）vehicles come out of the capital city, his car being the only one on roads.

A few foreign soldiers come up to him, one, two, three, four, five. The leader bends over to have a look at the old car, then at him. “Where do you come from and where are you going?” With a smile on his face, he answers with a broken speech in the tongue that the soldier can understand, “Sir, I come from the capital. I’m leaving that place because it is a very dangerous place to be, with the war and everything.”

While talking, he hands a cigarette over to the soldier, then lights it up for him.

“When will the war end?” he asks.

“It won’t take long. We’ll soon give all of you in the capital the true freedom.” The soldier breathes a deep mouthful. He seems to have spotted the photo in the car, “The cigarette is not bad at all. Are those your wife and kids? I have two of my own, roughly the same age.”

“Oh, yes, they are mine and they are constantly on my mind. They left the city a bit earlier, and I’m on my way to be reunited with them. Perhaps I’m never coming back. Driving a cab around during war times is too dangerous. I’m giving up the business.” He looks at the soldier, still smiling.

“After we overthrow your dictator(独裁者), you won’t have that to worry about. You can come back and pick up your life again.” The soldier is leaning on the door of the car. It is perhaps the first time in many days that he has seen a happy face among the local people. It cheers him up.

“Maybe, but I have to go to see my family. If you would pay us a visit, my wife will prepare a good meal for all of you. Come with me. This is going to be my last business run and I won’t even charge you.”

“Can’t make it. We’re on duty. Give our regards to your wife and kids.” The soldier is a bit excited, thinking maybe quite some locals have open arms for them after all. “Oh, yes, I almost forgot. The south is battle-infected. Where is your family?”

Still smiling, he picks up the broken picture frame, presses a kiss on the photo, then turns around, staring into the eyes of that soldier, not quite himself from excitement, and the other foreign soldiers holding guns. Words drop out of his lips slowly but firmly:

“Paradise.”

Perhaps the last thing he sees is the confused, fearful, twisted expression on the face of that soldier, and the cigarette end dropping from his fingers.

Then he pushes the button.
