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,并在答题卡上将该项涂黑。
A
Soon it may be harder to stop and smell the roses.
Growing levels of air pollution from power plants and automobiles have reduced flower fragrances (芬芳) by up to 90 percent in the US.That is compared with pre-industrial levels,a new study has found.
The trend is unpleasant for human noses,but may be life - threatening for bees and butterflies.
"Many insects find flowers by folowing the scent(香味) produced by those flowers," said the studies lead author Jose D.Fuentes,an environmental scientist at the University of Virginia.
"The increasing pollution makes it difficult for them to locate the flowers and feed on their nectar(花蜜)."
Scientists have alrady known that flowers produce scent molecules(分子) that bond with pollutants.The process breaks down the plants' sweet smell.
With more pollution in the air,the scent molecules don't remain effective as long and travel shorter distances on the wind.
The new study suggests that in the mid - 19th century,when pollution levels were first recorded,scent molecules would have been able to travel some 1,000 to 1,200 meters.
Today,in the polluted air found downwind of large cities,scentst may only make it some 200 to 300 meters.
The report was recently published in the journal,Atmospheric Environment.
Bee farmers have reported that bee populations are dropping dramatically in many parts of the world in recent years. Could these missing scents be a factor?
Scientists trying to hind the cause of bee population declines have blamed bacteria,pesticides,and even cellphone radiation.
Jay Evans,an entomologist(昆虫学者) at the US Department of Agriculture's bee research laboratory,was interested in the new study.But he says he hasn't seen bee behavior that suggests trouble with scents.
"Over the last couple of summers I don't think the bees in this area were bringing in much less food,"he said.
"It might be that they had to work harder,but it seems like as long as there were bees to collect food they were finding flowers somewhere."
But Fuentes fears that the fading smell of flowers may stress insects that are already faced with other threats.
"The effects shown in these studies will simply exacerbate whatever the bees are going through right now,"he said.
"It's something that is really worthwhile paying attention to."
56.What's the passage mainly about?
A.How greatly air plooution affects our lives.
B.Effects of air pollution on bee populations.
C.Measures to fight air pollution.
D.The rapid decline of bee populations in the world.
57.According to the passage,Jay Evans probably agrees that ______ .
A.bees are the insect that suffers most from air pollution
B.bees are at risk of dying out owing to air pollution
C.the fading smell of flowers doesn't affect bees so greatly as was thought
D.as is often the case,bees fail to locate the flowers because of the missing scents
58.The word"exacerbate" in the last paragraph but one probably means ______.
A.worsen B.improve C.get rid of D.decrease
59.Which of the following is NOT true according to the passage?
A.The more air pollution there is in a region,the greater the destruction of the flower scents.
B.Bacteria,pesticides,and cellphone radiation are blamed for causing the decline of bees.
C.The scent molecules produced by flowers in a less polluted environment oculd travel longer and farther.
D.Air pollution does more harm to insects such as bees and butterflies than human beings.

Colour helps you see things. But man and some monkeys and apes (猿)are the only mammals (哺乳动物) that can see colour. To any other mammal, such as the dog, the world looks like a black-and-white photo. Dogs hunt mainly by listening and sniffing (闻).
Like other animals, dogs see best when things move. The animals they hunt seem to know this. A hunted rabbit or deer will “freeze”. Then the dog may not see it at all.
Birds can see colour. They need to, because they fly and need to find places to land.Colour helps them judge distance and shape. In this way they are able to catch bugs (昆虫) in the air or to light on branches.
Some birds see things even better than you do. The birds that eat bugs can see them from far away. And even a very young bird can see a hawk high in the sky. So sharp eyes and a sense of colour help birds find food and also help them find where their enemies are.
(1)________can see colour.
[ ]
A.All the animals
B.All the mammals
C.Man and dogs
D.Birds and monkeys
(2)In order to find their food, dogs mainly use their _______
[ ]
(3)The word “freeze” in the passage means _________.
[ ]
A.the hunted animals are frozen on the ground because of cold weather
B.the hunted animals' temperature is becoming lower and lower until it drops below 0℃
C.the hunted animals will stop running and stay in the same place without movement
D.the hunted animals are so frightened that they can't move any longer
(4)Colour helps birds_______
[ ]
A.see better than man
B.see better than dogs
C.see how colourful the world is
D.see clearly where food and enemies are
(5)To dogs,they see best when things are ________
[ ]
阅读下列短文, 从所给的四个选项中, 选出最佳答案。
Bats are the only flying mammals(哺乳动物)in the world. They can't see very well, but they have no trouble flying on the darkest nights and catching the insects (昆虫) that they eat. How do bats manage to fly by radar (雷达)? The bats' radar system (系统) works the same way as the one the ships and planes use, like the radio signals that bounce (反射) back when they hit an object. As a bat flies through the air, he sends out of series (系列) of sounds, thirty to sixty per second. The sound can't be heard by the human ear. If the sounds hit an object, these returned sound signals tell the bat where the object is. The bats' radar system is very good.Tests have been made with bats in a crowded room. Blind in the light, the bats could fly about the room and never touch any object.

[ ]
A. radar system works
B. bats sent out sound signals

B. they hear all kinds of sounds
C. they hit objects and bounce back
D. they send out sound signals
(4) The bat's ears pick up the sounds. This means__________.
[ ]
A. the bat can hear the returned sound signals
