China is a land of bicycles.At least it was back in 1992 when I travelled the country.Back then everyone seemed to be riding a bicycle.Millions of them,all black.Cars were rare.Yet since my arrival in Beijing last year,I've found the opposite is true.There were millions of cars.However,people still use their bicycles to get around.For many,it's the easiest and cheappiest way to travel today. Bicycles also come in different colours---silver,green,red,blue,yellow,whatever you want.
It's fun watching people biking. They rush quickly through crossroads,move skillfully through traffic,and ride even on sidewalks(人行道). Bicycles allow people the freedom to move about that cars just can't provide.
Eager to be part of this aspect of Chinese culture, I decided to buy a bicycle. Great weather accompanied my great buy. I immediately jumped up on my bicycle seat and started to ride.
My first ride home was orderly(守秩序的).To be safe,I stayed with a "pack"of bikers while cars on the streets came running swiftly out of nowhere at times. I didn't want to get hit.So I took the ride carefully.
Crossing the streets was the biggest problem. It was a lot like crossing a major highway back in the United States. The streets here were wide,so crossing took time,skill and a little bit of luck.
I finally made it home. The feeling on the bicycle was amazing. The air hitting my face and going through my air was wonderful. I was sitting on top of the world as I passed by places and people.Biking made me feel alive.

The sound of a mosquito can mean trouble in many parts of the world. The bite of the mosquito can be deadly. The insects carry serious diseases like malaria. It is estimated that almost 630,000 people died from malaria and malaria-related causes in 2012, and most of these cases were in African countries.
In the United States, a group of California scientists is working to develop a more effective and less costly substance(物质)to protect people from mosquitoes. The researchers are investigating the sense of smell in mosquitoes. They found the insects use the same receptor(感受器)for identifying carbon dioxide in human breath as they do for the smell of our skin. Anandasankar Ray, who is leading the investigation, says scientists tested more than a million chemical compounds(化合物)until they found a substance called Ethyl pyruvate. He says Ethyl pyruvate makes the mosquitoes' receptor inactive. ”When we apply Ethyl pyruvate to a human arm and offer it to hungry mosquitoes in a cage, very few of the mosquitoes are attracted to the human arm because only a few of them are able to smell it out,” said Ray.
Genevieve Tauxe, a member of the research team, says it was not easy to find the neurons (神经元)of nose cells that recognise both the smell of human breath and skin. "With the device used to examine mosquitoes, we are able to insert a very small electrode(电极)into the part of the mosquitoes' nose, where its smelling neurons are and where the smell is happening," said Tauxe.
Anandasankar Ray says a product based on Ethyl pyruvate may cost less to produce than DEFT，the most effective chemical treatment now in use. He says DEFT is too costly for most people who live in areas affected by malaria.
“Perhaps by finding smells that can attack other target receptors, we will be able to improve upon DEFT and finally have the next generation of insect behavior control products," said Ray.The best title for the passage is most probably _______________________________.
| A．Scientists Find New Substance to Fight Mosquitoes |

PERTH—Search crews will send a submarine(潜航器)deep into the Indian Ocean on Monday for the first time to try to determine whether signals detected by sound-locating equipment are from the missing Malaysian plane's black boxes, the Australian head of the search said.
Angus Houst on said the crew on board the Ocean Shield will send the underwater vehicle sometime Monday evening. The Bluefin 21 submarine can create a sonar(声呐)map of the area to chartany wreckage(残骸)on the seafloor.
The move comes after crews picked up a series of underwater sounds over the past two weeks that were consistent with an aircraft's black boxes.
“We haven’t had a single detection in six days, and l guess it’s time to go under water,” said Houston.
“Analysis of the four signals has reduced the search area on the ocean floor. The experts have therefore determined that the Australian Defense Vessel Ocean Shield will stop searching with the Towed Pinger Locator(拖曳声波定位仪)later today and use the underwater vehicle Bluefin 21 as soon as possible," he said at a news conference in Perth.
But Houston warned the switch to the submarine will not automatically "result in the detection of the aircraft wreckage. It may not.”
He said the submarine will take 24 hours to do each task, including two hours to dive, 16 hours to search the bottom, then two more hours hack up and four hours to download data.
Recovering the plane's flight data and cockpit(飞行员座舱)voice recorders is necessary For investigators to try to figure out what happened to Flight 370, which disappeared on March 8.
Houston said the search using the submarine will be a slaw and painstaking process.
The submarine takes six times longer to cover the same area as the pinger locator,and will need about six weeks to two months to examine the present underwater zone. The signals are also coming from 4,500 meters (15,000 feet) below the surface, which is the deepest the submarine can dive.The submarine will be sent deep into the Indian Ocean on Monday to _____ .
| A．create a sonar trap of the area |
| B．pick up underwater sounds |
| C．see if the signals detected are from the target black boxes |
| D．reduce the search area on the ocean floor |
According to the passage, the submarine_______ .
| A．will download data of the black boxes |
| B．can find the aircraft wreckage within 24 hours |
| C．will recover the plane's flight data and voice recorder |
| D．can dive to a depth of no more than 4,500 meters |
The underlined sentences in the passage indicate that______.
| A．the switch of the submarine may not function properly |
| B．the Ocean Shield will switch to submarine when it is necessary |
| C．the submarine will detect the wreckage of the plane automatically |
| D．the detection of the wreckage can't be guaranteed by using the submarine |
The search will be a slow and painstaking process, mainly because _____ .
| A．the underwater sounds were consistent with an aircraft's black boxes |
| B．the submarine travels slowly and the ocean is deep |
| C．they haven't had a single detection in six days |
| D．Ocean Shield stops searching wine the towed pinger locator |
The slogan “a dog is for life, not just for Christmas” has been going strong for 27 years now. Dogs and cats have been popular Christmas gifts in the gifts in the UK and Europe for many years. But some people still haven't quite got the message.
The slogan still holds good. Some 105,000 dogs were rounded up by local government last year because they had been abandoned, many of them shortly after the festival season.
The main reason given by owners for handing their dogs over to the Dogs Trust is that the dogs need more attention than they can give; behavioral problems and moving home are also reasons given.
But Eleanor Silk, the Trust's communications director, says, “It's often four or five months after Christmas, in early summer, when owners find that the dog has got too big and too active, or it hasn't been trained properly and has caused damage around the home.”
In any case, some organizations that help pets are quick to point out that if you are serious about getting a puppy as a pet, Christmas is not the time to do it. Puppies need to get used to their new surroundings, to be introduced to a routine, and to be looked after like small children. It's hard to meet any of these needs at Christmas. What's more, pulling a puppy out of a Christmas stocking in itself sends the wrong message to children. It encourages children to think of the puppy as a toy, rather than a responsibility.
Appreciating what you're taking on with a dog can be a sobering (清醒的) realization. “For life” means thinking about the effect they'll have on your life. It also infers that you will need to care for the dog for its whole life.What would be the best title for the passage?
| A．Dogs and Cats—the Most Popular Christmas Gifts |
| B．A pet is for Life, Not just for Christmas |
| C．How to Take Care of Your Pets over Christmas |
| D．Let's Help Those Abandoned Pets |
According to the passage, which of the following is NOT a reason for pets to be abandoned?
| A．Pets spread some diseases. |
| B．Pets damage some things in the house. |
| C．The owners can't take good care of the pets. |
| D．The owners have to move to other places. |
The fifth paragraph mainly tells us ________
| A．how to take best care of Christmas pets. |
| B．the right time to have a puppy as a pet. |
| C．the reason why Christmas is not the time to get a pet. |
| D．the worries about Christmas pets from organizations that help pets. |
Why is the author against the idea of putting a dog in the Christmas stocking as a Christmas gift?
| A．Because these dogs can still cause damage. |
| B．Because children will not take dogs seriously. |
| C．Because children don’t like to have dogs as Christmas gifts. |
| D．Because a Christmas stocking is not big enough to put a dog in. |
