The secret of carrier pigeons' unbelievable ability to find their way home has been discovered by scientists: the feathered navigators follow the roads just like we do.
Scientists at Oxford University spent 10 years studying homing pigeons using global positioning satellite (GPS) and got a surprising result. The birds often don't use the sun to decide their directions. Instead, they fly along motorways, turn at crossings and even go around roundabouts (绕道) , adding miles to their journeys.
“It really has knocked our research team sideways to find that after a decade-long international study, pigeons appear to ignore their inbuilt directional instincts (本能) and follow the road system,” said Prof Tim Guilford, reader in animal behavior at Oxford University's Department of Zoology.
Guilford said pigeons use their own navigational system (导航系统) when doing long distance trips or when a bird does a journey for the first time.
“But once homing pigeons have flown a journey more than once, they can fly home on a habitual route, much as we do when we are driving or walking home from work,” said Guilford.
“In short, it looks like it is mentally easier for a bird to fly down a road. They are just making their journeys as simple as possible.” What would be the best title of the passage?

Next time you hear a funny joke you’d better not laugh too hard. According to a paper published by the British Medical Journal, laughter isn’t always the best medicine. Sometimes it can even be harmful. Professor Robin Ferner from the University of Birmingham, one of the authors of the study, found that bad things could happen to people who laughed too much. He says: “We found people with heartbeat problems which had stopped their heart, we found people who had fainted, and we found people who’d dislocated their jaws or burst their lungs.”
It seems that laughing can be no laughing matter. But it’s not all doom and gloom. Professor Ferner says there are benefits to laughing when you want to lose weight, for example. Yes, that’s right: laugh and be slimmer! Professor Ferner explains that: “You use energy when you laugh, you move your diaphragm (横膈膜), you expand your lungs, and both those things can be helpful.”
According to the research, laughing for a quarter of an hour can burn up to 40 calories, and if you laughed all day you’d use up about 2,000 calories, which is what most people consume in a day. But don’t do that or you might end up with a painful jaw. Ouch! Or you might find people looking at you in a funny way.
But I don’t want to finish this article leaving you feeling desperate. Laughter comes naturally for most of us. Babies begin to laugh at around 3-6 months. So give in to your sense of humour and keep smiling. Life is short anyway.Laughing too much may cause the following harmful results EXCEPT_________.
| A．heart stop | B．diaphragm movement |
| C．lung burst | D．jaw dislocation |
The underlined phrase “doom and gloom” in Paragraph 2 probably means_______.
| A．hopeless | B．funny | C．painful | D．nervous |
What is the author’s attitude towards laughing in the last paragraph?
| A．Uninterested. | B．Disapproving. |
| C．Worried. | D．Favorable |
San Francisco, unofficially regarded as one of the homeless capitals of the US, counts nearly 6,500 homeless people, with 4,300 living on the street.
Among the many problems that the homeless face is little or no access to showers. San Francisco only has about 16 to 20 shower stations to accommodate them. But Doniece Sandoval has made it her task to change that. “Homelessness is something you can’t really miss,” the 51-year-old woman said. She started Lava Mae, a sort of showers on wheels, a new project that aims to turn old city buses into shower stations for the homeless.
“One day I passed a woman in the street and she was very dirty and basically crying, and I heard her say that she would never be clean. But I was wondering what her opportunities were to actually get clean,” Sandoval said.
Sandoval was inspired to start Lava Mae. The project has already been welcomed with open arms in the city. The Transportation Agency has donated one bus for the cause and is willing to donate three more if the project succeeds. Sandoval hopes the first bus will be able to hit the road in May this year. The Public Commission has also agreed to let the buses plug into fire hydrants(消防龙头)around the city if Lava Mae pays for the water.
One of Lava Mae’s biggest supporters is Bevan Dufty, the director of Housing Opportunity, Partnerships & Engagement under the mayor of San Francisco. “For people who are unhoused, access to showers is very difficult. Shower buses are something that could potentially be deployed (部署)in response to an emergency, so it is relevant to all San Franciscans," Dufty said. “Doniece has done an incredible job as a citizen who cares about helping the poor. We are very excited to see Lava Mae become real soon. ”
Each bus will have two shower stations and Sandoval expects that by 2015, they’ll be able to provide 2000 showers a week. What problem does San Francisco face according to the text?
A. The city has the most homeless people in the USA.
B. There are no shower stations for the homeless in the city.
C. It’s hard for homeless people in the city to take showers.
D. Few citizens in the city care about the homeless.What does the underlined word ''them” in Paragraph 2 refer to?
| A．City problems. | B．Shower stations. |
| C．Old buses. | D．The homeless. |
. Which of the following best describes Doniece Sandoval?
| A．Brave and independent. | B．Caring and responsible. |
| C．Honest and determined. | D．Friendly and humorous. |
What can we learn from Dufty’s words?
| A．All San Franciscans are excited to use Lava Mae. |
| B．Emergencies in San Francisco will be prevented by Lava Mae. |
| C．Dufty thinks highly of Doniece's way of helping the poor. |
| D．The mayor of San Francisco will support Doniece financially. |
What can be a suitable title for the text?
| A．A Newly Invented Way of Shower |
| B．Showers on Wheels for the Homeless |
| C．The Health Problem of the Homeless |
| D．Lave Mae---a new name for old city buses |

Do you know that women’s brains are smaller than men’s? The average women’s brain weighs 10% less than men’s. Since researches have shown that the bigger the brain, the cleverer the animal, men must be more intelligent than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain consists of “grey matter” and “white matter”. While men have more of the latter, the amount of “thinking” brain is almost exactly the same in both sexes.
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls tend to learn to speak earlier, and that women can understand sorts of information from different sources at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.
There are other important differences between two sexes. As white matter is the key to spatial(空间的) tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries—why men refuse to ask for directions … and women often need to!
The differences begin when fetuses(胎儿) are about nine weeks old, which can be seen in the action of children as young as one. A boy would try to climb a barrier (障碍物) before him or push it down while a girl would attract help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research. www..com
