21、GPS has completely transformed how we get around. But other animals have long had their navigation (领航) systems built right in.
“We know their eyes are quite sensitive to polarized (偏振的) light and the sky has a particular pattern of polarized light relative to the position of the sun,” Barbara Webb, a researcher at the University of Edinburgh, says.
You can see polarized light firsthand if you take a pair of polarized sunglasses and spin them against the sky-the light passing through the glasses changes. Webb says the insects have polarization like that built into their many eyes. “You can think of it as having lots of sunglasses pointing in different directions.”
But Webb was curious whether there’s really enough information in the sky to give insects an accurate sense of direction. So her team built a sensor (传感器) modeled after a desert ant eye and put it under artificial light meant to simulate the sky. They then put that sensor into a model meant to model the brains of desert ants and other insects. And they found that with the insects’ sensing and processing equipment, they can likely sense direction down to just a couple degrees of error.
A system based on that of insects could someday be a cheap, low-energy choice to GPS. Insects have very tiny brains. A brain the size of a pinhead that’s using hardly any energy. And yet they’re still able to navigate better than we can with GPS, which is surprising. Webb is now working on building a robot that can use light to get its directions.
【1】What can we learn from the text?
A.GPS is not accurate enough.
B.Insects have better eyes than humans.
C.Light changes passing through polarized sunglasses.
D.Insects have tiny brains that use no energy.
【2】What does the underlined word “simulate” in paragraph 4 probably mean?
A.Pretend.
B.Cover.
C.Block.
D.See.
【3】What did Webb’s research find?
A.Insects can’t find their ways during nights.
B.Insects can find directions with little mistakes.
C.Insects always make mistakes finding directions.
D.Insects have sensing and processing equipment in their eyes.
【4】Which of the following can best describe insects’ navigation ability?
A.Disappointing.
B.Interesting.
C.Amazing.
D.Confusing.
22、 Large oceangoing vessels like oil tankers and cruise ships produce noise that travels long distances underwater. That audio pollution can disturb the sounds that marine mammals, fish and other animals use to communicate.
Emily Carter, a sensory ecologist from University of Exeter wondered whether ship noise might also be harmful to animals that don’t rely on sound for communication. For example, young shore crabs that use camouflage (伪装) to hide from predators. “So they can actually change their color to match whatever it is that they’re sitting on, basically to make it harder for predators to find them.” Carter explained.
She suspected that stress from ship noise might affect the change process. To find out, she and her colleagues collected shore crabs with dark shells and brought them back to the lab. They placed the crabs in tanks full of white small stones. An underwater speaker in each tank played quiet natural sounds at all times. One group of crabs also heard loud natural sounds every hour. But another group was subjected to hourly recordings of large ships.
Carter says shorebirds, which eat the crabs, can see UV light, so she used ultraviolet (紫外线) photography to determine how well the crabs blended into their new habitat over time.
“Through the eyes of a shorebird — so through bird’s perspective — were they camouflaged? Weren’t they camouflaged? How obvious would they be?”
After eight weeks, the crabs that heard only natural sounds had become much lighter and were well camouflaged. But the ones that were exposed to the ship noise didn’t change color as much. And then, as a result, they weren’t as camouflaged at the end of the experiment. So they’d be much more manifest to predator.
Carter says the stress caused by ship noise may affect hormones that regulate color change in crabs or destroy the energy needed to make the change efficiently. The research not only puts a spotlight on the unintended consequences of noise pollution, but is a reminder that too much stress isn’t just bad for people — it can also be deadly to wildlife that needs some peace and quiet.
【1】Why is ultraviolet photography used in the experiment?
A.To scare away shorebirds.
B.To kill the bacteria in crabs’ new habitat.
C.To test the effectiveness of crab’s camouflage.
D.To monitor the shorebird population in nighttime.
【2】What does the underlined word “manifest” mean in Paragraph 6?
A.Avoidable.
B.Noticeable.
C.Changeable.
D.Adjustable.
【3】Which of the following is true?
A.Carter conducted the experiment on her own.
B.The crab that heard natural sound lost some weight.
C.Carter created three kinds of living environment for crabs.
D.The crab that heard ship noise slightly changed their color.
【4】What did the research find?
A.Noises do harm to us people.
B.Wildlife needs a quiet environment.
C.Crabs aren’t camouflaged in new habitats.
D.Stress can change the hormones in humans.
23、阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项
Tips for Cycle Trips
Cycling has many advantages as a form of travel, as it is the fastest way to travel by human Power, and slow enough to allow the type of local involvement that is impossible with powered travel.Cycle travel is a cheap form of transportation.
Distance
On level terrain(地形),without a headwind, a cyclist of average fitness on a touring bike can comfortably cover 60-120km a day.Distances of up to 250km a day are possible, but anything much beyond 120km will require considerable physical tension and not allow many stops to enjoy the places you visit.For many,80-100km a day will be the most suitable distance to aim for, as it will give a sense of achievement and also leave plenty of time for meals and activities.
Geography
The gradient(坡度)of the trip will reduce your range.A basic rule is that for every 100 metres of altitude you climb, you should add an extra 15 minutes to your journey time.In hilly or mountainous areas, the easiest routes for cycling are downstream along major rivers, as overall they will be downhill.A long, roundabout route along a river will usually be easier than a short, direct route over a hill or mountain pass.However, it is worth bearing in mind that the most scenic routes often come from hilly terrain.
Eat
Food choice depends largely on where you are, so see the respective sections for more information about foods. As you will be working hard, it's important to get enough energy in your food. On long trips away from major towns-there may be little quality food available, so be prepared to live on candy bars, prepared meat products and the like if the need arises.
Sleep
While you can take a tent with you, many hotels and especially campsites can accommodate cyclists. However, there are also some hotels that may be less used to accommodating cyclists.If you are exploring an unfamiliar world, asking about the accommodation spares you the search for a new place to stay after a long exhausting day of travel.
【1】Which distance does the author suggest to ordinary cyclists a day?
A.50km. B.90km.
C.130km. D.250km.
【2】Form the passage, we can learn that_____________.
A.high quality food is easy to get on long trips
B.hotels seldom provide accommodation for cyclists
C.cycling over a mountain is challenging but worthy
D.it takes cyclists 15 minutes to climb 100m of altitude
【3】We can probably read this passage in___________.
A.a geography book B.a research report
C.a science fiction D.a travel magazine
24、 Generally,when rescue workers save the lives of people in emergency situations,they never see each other again.However,this was not the case for Mike Wilson,a member of the U.S.Air Force,and Jennifer Brown,the"little"girl Wilson picked up from the waters of Hurricane Ike in 2008.

The girl tells PEOPLE:"The program was very interesting and a challenge for me because I had never done it before".She even plans to join the military one day."I am Proud of her no matter what she does and will support her in everything she does,"Wilson said."I think she understands service and I believe that she will do great things no matter what she chooses."
