Ⅲ.阅读理解(共20小题；每小题2分，满分40分)
A
Ears are for hear ( http: / / www.21cnjy.com )ing－everyone knows that.But for a creature called the Cuvier's beaked whale, hearing starts in the throat, a new study found.
The observation ( http: / / www.21cnjy.com ) might help explain how all whales hear.The work might also help scientists understand how animals are affected by underwater sonar (声呐)．This sonar，used by some ships，sends out sound waves to locate underwater objects.
The Cuvier's beaked ( http: / / www.21cnjy.com ) whale is a so called toothed whale.Toothed whales dive deep into the ocean in search of food.As the whales hunt, they produce sounds that reach objects and then return to the whales.This allows the animals to“see”the shape, size, and location of objects，even when they're 1,000 meters under the sea, where it is totally dark.21cnjy.com
To better understan ( http: / / www.21cnjy.com )d how the whale hears，researchers from San Diego State University in California took X rays of two Cuvier's beaked whales.The whales had died and washed up on the beach.
The Cranford a ( http: / / www.21cnjy.com )nd his colleagues used the images to make a computer model of a Cuvier's beaked whale's head.Then, they modeled the process of sound traveling through the head.
The researchers kne ( http: / / www.21cnjy.com )w that some sounds get to the ears of a toothed whale through a structure called“the window for sound”．Found on the lower jaw, this structure is very thin on the outside and has a large pad(垫) of fat on the inside.
When the researcher ( http: / / www.21cnjy.com )s and their computer model to work out how sound waves travel in the whale's head, they were surprised to find that sounds coming from right in front of the whale actually travel under the animal's jaw.From there, sound waves move through the throat，into a hole in the back of the jaw, and finally to the pad of fat near the animal's ears.21教育网
36．Toothed whales __ ( http: / / www.21cnjy.com )______ to search for what they will eat under the sea.
A．measure the shape and size of their objects
B．watch deep into the sea
C．ask other whales to work together
D．give out signals and wait for them to return
37．Researchers took X ( http: / / www.21cnjy.com )rays of two Cuvier's beaked whales in order to ________.21教育名师原创作品
A．find out why they had died and washed up on the beach
B．make a computer model of a Cuvier's beaked whale's head
C．make sure that sound travels through the head
D．know more about the way the whale hears
38．Which of the fo ( http: / / www.21cnjy.com )llowing describes the way taken by sound waves through a Cuvier's beaked whale
A．A hole in the back of the jaw→the ears→the jaw→the throat.
B．The jaw→the throat→a hole in the back of the jaw→the ears.
C．The throat→the jaw→the ears→a hole in the back of the jaw.
D．The ears→the throat→a hole in the back of the jaw→the jaw.
39．According to the passage we know that ________.
A．the throat is important to the Cuvier's beaked whale's hearing
B．ships send out sound waves like a Cuvier's beaked whale
C．the ears are actually useless to the Cuvier's beaked whale
D．the researchers haven't found how the whales hear
40．The passage is written mainly to ________.

(2013·天津高考)Last nigh ( http: / / www.21cnjy.com )t's meteor (流星) shower left many people in the community dissatisfied and demanding answers.According to Gabe Rothschild，Emerald Valley's mayor，people gathered in the suburbs of the city，carrying heavy telescopes，expecting to watch the brightly burning meteors passing through the sky.What they found instead was a sky so brightened by the city's lights that it darkened the light of the meteors passing overhead.
“My family was so ( http: / / www.21cnjy.com ) frustrated，”admitted town resident Duane Cosby.“We wanted to make this an unforgettable family outing，but it turned out to be a huge disappointment.”
Astronomers—scient ( http: / / www.21cnjy.com )ists who study stars and planets—have been complaining about this problem for decades.They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past.They call on people and the government to take measures to fight against it.
There is yet a popu ( http: / / www.21cnjy.com )lation besides professional and amateur star observers that suffers even more from light pollution.This population consists of birds，bats，frogs，snakes，etc.For example，outdoor lighting severely affects migrating (迁徙的) birds.According to the International Dark Sky Association ，“100 million birds a year throughout North America die in crashes with lighted buildings and towers.”
Countless more ( http: / / www.21cnjy.com ) animal casualties (伤亡) result from the use of artificial lighting.Clearly，people enjoy the benefits of lighting their evenings，but some scientists think it can be harmful for humans，too.They worry that exposure to light while sleeping can increase a person's chances of getting cancer.
Emerald Valle ( http: / / www.21cnjy.com )y is only one community that is becoming aware of the negative effects of light pollution.For years，Flagstaff，Arizona，has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory.Similar efforts have been made worldwide，and a movement is underway to remind us to turn off lights when we are not using them，so that other creatures can share the night.
41．It happened last night that ________.
A．the city's lights affected the meteor watching
B．the meteors flew past before being noticed
C．the city light show attracted many people
D．the meteor watching ended up a social outing
42．What do the astronomers complain about
A．Meteor showers occur less often than before.
B．Their observation equipment is in poor repair.
C．Light pollution has remained unsolved for years.【出处：21教育名师】
D．Their eyesight is failing due to artificial lighting.
43．What is the author concerned about according to Paragraph 4
A．Birds may take other migration paths.
B．Animals' living habits may change suddenly.
C．Varieties of animals will become sharply reduced.
D．Animals' survival is threatened by outdoor lighting.
44．Lighting regulatio ( http: / / www.21cnjy.com )ns in Flagstaff，Arizona are put into effect to ________.
A．lessen the chance of getting cancer
B．create an ideal observation condition
C．ensure citizens a good sleep at night
D．enable all creatures to live in harmony
45．What message does the author most want to give us
A．Saving wildlife is saving ourselves.
B．Great efforts should be made to save energy.
C．Human activities should be environmentally friendly.
D．New equipment should be introduced for space study.

“The noise made by boa ( http: / / www.21cnjy.com )ts of whale watching tourists may be causing communication problems for the animals，”British researchers said last week.
Whale watching is a po ( http: / / www.21cnjy.com )pular tourist activity in places where groups of killer whales(虎鲸)live.Every day，dozens of boats filled with tourists go to watch the beautiful animals.Unfortunately，the engines of the boats make a lot of noise，and that may be causing problems for the whales，according to a report in the US science magazine Nature.21·世纪*教育网
The whales ( http: / / www.21cnjy.com ) travel in groups, and communicate with each other through sonic (声波的) calls that some scientists refer to as singing.The sounds of the boat engines may be creating too much background noise for the whales to be able to hear each other.
The researchers ( http: / / www.21cnjy.com )listened to recordings of whale calls made between 15 and 25 years ago，before whale watching became popular.These were compared to more recent recordings.
They found that the a ( http: / / www.21cnjy.com )nimals have started to sing for longer than they used to, like a person shouting to a friend across a noisy room.
It is believed that ( http: / / www.21cnjy.com ) the whales are trying to communicate hunting or breeding information.Scientists said that, if this is prevented, the future of the world's whale population could be in danger.
“Animals become s ( http: / / www.21cnjy.com )low in mind and repeat themselves in noisy areas，”said Volker Deecke，a Canadian biologist.“They have to say things twice or three times in order to be understood.”
The killer whale ( http: / / www.21cnjy.com )s studied were living off the coast of northwestern America.The number of killer whales in this area has been falling for several years, but scientists are not sure why.
46．What does the underlined word in Paragraph 6 mean
A．Singing to others.
B．Producing young.
C．Caring about the old.
D．Hunting for food.
47．The passage mainly tells us ________.
A．the problems of whale watching
B．how killer whales communicate with each other
C．the reduced population of killer whales caused by whale watching
D．hearing problems of the killer whales caused by whale watching
48．Now in a noisy background, the killer whales have to ________.
A．sing in a louder voice
B．sing longer
C．travel in smaller groups
D．get nearer to each other
49．Scientists believe that killer whales sing to ________.21世纪教育网版权所有
A．warn each other of dangers
B．keep in the same group
C．send useful information
D．enjoy themselves
50．From the passage，we can feel that the author is ________.
A．angry B．hopeful
C．worried D．disappointed

Sharks have been sw ( http: / / www.21cnjy.com )imming in the ocean for millions of years.They were on Earth even before dinosaurs! At the top of the world's ocean's food chain, sharks help keep the population of other ocean animals in balance.A large drop in the number of sharks can cause serious problems for all ocean animals.Saving sharks makes sense!
Many people are a ( http: / / www.21cnjy.com )fraid of sharks.But most sharks are harmless.Only a small percentage of sharks are known to attack humans.It adapts (适应)well to new habitats and eats whatever is available.However, today, sharks are in trouble.Nearly one third of the 400 shark species are in danger of extinction, largely due to overfishing.Each year，tens of millions of sharks are caught and killed just for their fins(鳍)．The fins are used to make shark fin soup.www-2-1-cnjy-com
Humane Society Int ( http: / / www.21cnjy.com )ernational(HSI)joined with the Jane Goodall Institute's Roots and Shoots program and Beijing Zoo to protect sharks.An exhibit at the zoo，“The Price Behind the Taste－Protect Sharks.Don't Eat Shark Fins”，was designed to tell people that shark finning is cruel and unnecessary.It's hoped that the activity will help put an end to the_practice.
Shark fin soup is a ( http: / / www.21cnjy.com )lso eaten in the United States.In fact，the numbers of some shark species in US waters have dropped 90 percent in the last 30 years.To_slow_the_fall，laws_against_the_sale_of_shark_fins_have_been_passed_in_several_states，including Hawaii，Oregon，Washington，and California.
It's hoped t ( http: / / www.21cnjy.com )hat with our help，sharks will continue to swim in the ocean for many more millions of years.

Ⅳ.阅读表达(共5小题；每小题3分，满分15分)
阅读下面的短文，请根据文后的要求答题(请注意问题后的词数要求)
(2013·江西高考)[ ( http: / / www.21cnjy.com )1]Fishing is probably the world's most popular sport. People spend many dollars each year on items like boats and four wheel drive vehicles. In addition, they spend money on fishing equipment, bait, fuel and boat repairs. And you can see that fishing can be an expensive pastime. Fishing lovers believe that their hobby is worth it. Others say that fishing is spoiling the environment and that it is a cruel hobby.2·1·c·n·j·y
[2]Supporters of ( http: / / www.21cnjy.com )fishing say that it is a nice hobby.Firstly，of the millions of people who fish for fun, most only catch enough fish to feed their families. They catch fish that are found in large numbers, so there is little danger to the species(种类)．
[3]Secondly, rec ( http: / / www.21cnjy.com )reational fishermen contribute to the economy. They spend money on equipment and other items，and they also spend it indirectly by paying taxes on their equipment and fuel. Those who travel to fishing spots pay for accommodation(食宿) and airfares. This money keeps people in work and provides new jobs each year.
[4]Thirdly, fishi ( http: / / www.21cnjy.com )ng is relaxing and fun so it lessens stress. Instead of turning to drugs or alcohol, it is far better to go fishing. People who are relaxed are generally healthier and much nicer to be near—except for the smell of the bait!
[5]Those who_ ( http: / / www.21cnjy.com )_______say that there are too many fish thoughtlessly taken from rivers, lakes, streams and oceans. This could lead to the dying out of some species. Modern cars and boats mean that people can fish in remote areas of the world, so no place is safe from greedy fishermen who take both males and females, leaving few fish to produce young.
[6]Those agains ( http: / / www.21cnjy.com )t fishing also say that it is a blood sport, which means that an animal must die so that a human can have fun. Many of the fish caught for sport are not suitable for eating, so they are thrown away. Once hooked, fish have no chance of escape.
56．What is the main idea of the passage (no more than 4 words)
______________________________________________________________
57．According to Paragr ( http: / / www.21cnjy.com )aph 2, why does fishing cause little danger to the species (no more than 8 words)

Those who___ ( http: / / www.21cnjy.com )_____________say that there are too many fish thoughtlessly taken from rivers，lakes，streams and oceans.2-1-c-n-j-y

43．D 细节理解题。由第四段最后 ( http: / / www.21cnjy.com )一句“...100 million birds a year throughout North America die in crashes with lighted buildings and towers.”可知，光污染已经给动物的生存带来了极大的威胁。

45．C 推理判断题。作者通过讲述光污染对观测天象的影响和对动物生存的威胁告诉我们，人类的行为要有利于环境。
46．B 词义理解题。由第六段第 ( http: / / www.21cnjy.com )二句可知，科学家说如果这件事情被阻止的话，世界上鲸的数量将会处于危险中，因此推断breeding指的是“繁殖”。

48．B 细节理解题。由第五段可知，因为受噪音干扰，现在虎鲸“唱”的时间比原来长。

In the morni ( http: / / www.21cnjy.com )ng, I did my homework with the help of my tutor.After lunch I surfed the Internet for the latest news and then I chatted with my friends online.In the afternoon, my parents and I went to visit my grandparents, who live on the other side of the city.We hadn't seen each other for long, so they were delighted to see us and we had dinner together in the evening.Since my family love singing very much, we took turns to sing songs after dinner.I sang a few popular songs.My grandparents sang some classic old songs.My mother and father especially enjoy singing together.I really had a great time that day.【来源：21·世纪·教育·网】

In Hawaii，you can e ( http: / / www.21cnjy.com )xperience swimming with dolphins.There are several companies on Oahu and the Big Island that offer a swim with these animals in the wild.These kinds of tours usually are combined with water sports such as snorkel(水下呼吸管)or scuba diving.21教育网
Dolphins are prote ( http: / / www.21cnjy.com )cted by the Marine Mammal Protection Act and it is against the law to become closer than 50 yards(45 m)to them.But these friendly animals can approach to check you out.You have to consider that if dolphins prefer to keep away，you should not try to swim close to them.If dolphins come close while you are swimming in the ocean，don't attempt to touch them and don't make aggressive or sudden movements.www.21-cn-jy.com
At the Sea Life ( http: / / www.21cnjy.com ) Park on Oahu，they have special dolphin programs that allow you to swim and hug dolphins；besides，you'll learn about these mammals' habits.The Dolphin Quest program will explain to you why dolphins are considered one of the most intelligent creatures.
Swimming with ( http: / / www.21cnjy.com )dolphins is one of the most attractive activities if you come to Hawaii.But Hawaii's underwater world is amazing and has many other species to watch：Humpback whales，Green sea turtles，Monk seals and so on.While you get in touch with this underworld，always have in mind the main rule of the ocean respect：Look but don't touch.

The water cycle soun ( http: / / www.21cnjy.com )ds like describing how water move above, on, and through the earth.But in fact, much more water is“in storage”for long periods of time than is actually moving through the cycle.The storehouses for the vast majority of all water on the earth are the oceans, and the oceans supply about 90 percent of the evaporated (蒸发的) water that goes into the water cycle.www-2-1-cnjy-com
Of course, no ( http: / / www.21cnjy.com )thing involving the water cycle is really permanent，even the amount of water in the oceans.Over the“short term”of hundreds of years, the oceans' volumes (总量) don't change much.But the amount of water in the oceans does change over the long term.For instance, just 1,000 years ago when William of Normandy invaded England，he landed near Hastings, which, though a few miles inland today, was then a coastal town.And a few thousand years ago humans crossed to North America from Asia at the (now underwater) Bering Strait.
During colde ( http: / / www.21cnjy.com )r climatic periods, more ice caps and glaciers (冰川) form and enough of the global water supply gathers as ice to reduce the amounts in other parts of the water cycle.The reverse (相反的情况) happens during warm periods.During the last ice age, glaciers covered almost one third of the earth's land mass, with the result that the ocean levels were about 400 feet lower than today.
Of course th ( http: / / www.21cnjy.com )e oceans are always in movement.The moon influences daily tides, which make the beach a more interesting place to visit.If you have ever been seasick, then you know how the ocean is never still.You might think that the water in the oceans moves around because of waves，which are driven by winds.But, actually, there are currents and“rivers”in the oceans that move massive amounts of water around the world.
6．Most of the water on the earth is stored in ________.
A．the ice caps and glaciers
B．the oceans
C．the groundwater
D．the atmosphere
7．The author mentions William of Normandy to show ________.
A．the permanent water cycle
B．the difference of Hastings' location
C．the changes in the amount of water in the oceans
D．the influence the oceans have on water cycle
8．According to Paragraph 3，what happens in warm periods
A．The ocean levels are lower than those during colder seasons.
B．One third of the earth is covered by glaciers.
C．The global water supply is not enough.
D．More water joins the water cycle.
9．The water in the oceans moves mainly because of ________.
A．waves driven by winds
B．the influence of the moon
C．currents and“rivers”in the oceans
D．the water cycle of the earth
10．What would the passage probably talk about next 2·1·c·n·j·y
A．Some interesting beaches for people to visit.
B．The results of the water movement in the
oceans.
C．The amount of water moving in the water cycle.
D．Examples of currents and“rivers”in the oceans.

However, the bay i ( http: / / www.21cnjy.com )s also full of harmful chemicals.Aviad Sheinin，professor of Haifa University's Maritime Studies Department, said he didn't think the dolphins were harmed by the pollution, but that he hoped they would swim back to sea soon.“It seems that they are quite relaxed.They don't seem to be stressed，”he said.
