阅读理解

    Research finds out why some people are constantly under attack from the bloodsucking insects while others walk free.

    For those unfortunate enough to feature highly on the mosquito hit list, summer nights can be synonymous with mosquito bites. Yet others hardly ever get bitten. So how do the bloodthirsty insects select their victims?

    The insects' tastes may seem arbitrary. However, research shows that when mosquitoes make their choices between potential victims, it all comes down to scent (气味).

    “Mosquitoes are attracted by carbon dioxide and heat, which everyone gives off. But mosquitoes are also attracted by certain scents,” says Karl-Martin Vagn Jensen, the head of research at the Department of Agricultural Science at Arhus University.

    According to Jensen, it has not yet been confirmed exactly what the scents in question are. But research does indicate that some scents are more attractive to mosquitoes than others.

    “All the lab employees rubbed petri dishes (培养皿) against their stomachs. In that way, their scents were put on the dishes, which were then put in a container full of mosquitoes,” he says. “The mosquitoes repeatedly landed on some of the petri dishes, but didn't go anywhere near the others.”

    Perhaps taking inspiration from popular fiction, there are also those who consider garlic as an excellent repellent (驱虫剂) against the winged bloodsuckers. According to the researcher, this strategy may not be entirely fruitless. “As far as I know, there is no scientific proof that eating garlic works. But there may be something to the theory that it's possible to mask scent with garlic,” he says. The only reliable method of protection against mosquitoes is to use repellents that are sold over the counter. It contains some smells that can confuse the mosquitoes. When the mosquito comes closer, it uses smell, heat and carbon dioxide to decide whether to bite. But if it is confused by a repellent, it will never get that far.

(1)、Which of the following can best replace the phrase underlined in Paragraph 2?
A、Be equal to. B、Be accessible to. C、Be harmful to. D、Be beneficial to.
(2)、What can we infer about the scents attracting mosquitoes?
A、Mosquitoes can be attracted by various scents. B、Some kinds of scents appeal to mosquitoes in particular. C、The lab employees use petri dishes to deposit their scents. D、Mosquitoes are arbitrary when it comes to different scents.
(3)、What is the main idea of the last Paragraph?
A、A new strategy is used in researching repellents. B、Garlic is considered to be an excellent repellent. C、Using repellents is an effective way against mosquitoes. D、The inspiration against mosquitoes is from popular fiction.
(4)、Where is the text most probably taken from?
A、Science fiction. B、A biography. C、A medical report. D、A research paper.

    It's true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. There's also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: The global warming over the last half - century has been caused mainly by human activity.”

    You may not believe that humans could change the planet's climate, but the basic science is well understood. Each year, billions of tons of greenhouse gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible blanket.

    Of course, the earth's climate has always been changing due to “natural” factors such as volcanic eruption or changes in solar, or cycles concerning the Earth's going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build - up of greenhouse gas in the atmosphere - not the warming we would expect from other possible causes.

    Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why aren't carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”

    The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths-one with human influence and one without. That obviously isn't possible, and so most scientists are careful not to state human influence as an absolute certainty.

Gorman is the youngest poet in U. S. history. She became the youth poet laureate (获奖者) of Los Angeles at age 16 in 2014 and the first national youth poet laureate three years later. She has recently completed her studies at Harvard University.

Her mother, Joan Wicks, teaches middle school in Watts. Shuttling among the neighborhoods gave Gorman a window to the world. Her like for poetry dates at least back to the third grade when her teacher read Ray Bradbury's Dandelion Wine to the class.

Gorman is a lot better at it now, but still working on her confidence as a public speaker. "Until two or maybe three years ago, I couldn't say the letter 'r'. Even to this day sometimes I struggle with it. I'd want to say 'girls can change the world', but I can not say so many letters in that statement, so I'd say things like 'young women can shape the globe'."

For Gorman, writing became a cure. "I used writing as a form of self expression to get my word on the page. So the more I recited out loud, the more I was able to teach myself how to pronounce these letters which for so long had been my greatest impediment." Gorman said she also used a song from Miranda's Pulitzer Prize-winning Broadway musical Hamilton to help with her speaking. "But I don't look at my disability as a weakness," said Gorman. "It's made me the performer that I am and the storyteller that I strive to be."

In September, Gorman will release Change Sings, the first of two children's books. The poet says she desires to publish a book "in which kids could see themselves as change-makers in history, rather than just observers".
