Researchers at San Diego Zoo have been studying what has been described as the “secret language” of elephants. They have been monitoring（監(jiān)測） communications between animals that cannot be heard by human ears.
The elephant’s call will be familiar to most people, but the animals also give out growls (低吼). Their growls, however, are only partly audible (聽得見的); two-thirds of the call is at frequencies that are too low to be picked up by our hearing. To learn more about the inaudible part of the growl, the team attached (附在……上面) a microphone sensitive to these low frequencies and a GPS tracking system to eight of the zoo’s female elephants. The researchers could then relate the noises the animals were making to what they were doing. Matt Anderson, who led the project, told BBC News, “We’re excited to learn how they interact and contact with one another.”
The team has already learned that pregnant females use this low frequency communication to announce to the rest of their long gestation (妊娠期) of over two years, in the last 12 days we see the low part of the growl, which we can’t hear. This we believe is to announce to the rest of the herd that the baby is upcoming,” said Dr Anderson.
The researchers believe that this also warns the elephants to look out for coming danger. “You may think that a baby calf of about 300 pounds would not be as open to predation (捕食) as other species,” he says. “But packs of hyenas (袋狼) are a big threat in the wild.”
Female elephants are only in season for around four days every four years and these calls can be heard by males more than two miles away.
小題1:Why some elephants’ call is called “secret language”?
A．Because it can’t be heard by human ears.
B．Because it can only be heard by female elephants.
C．Because people don’t know its meanings.
D．Because people haven’t studied it completely.
小題2:By using a sensitive microphone and a GPS tracking system, the researchers wanted to find out             .
A．where the elephants usually go
B．what the elephants’ growls really mean
C．how mother elephants raise baby calves
D．how elephants protect their babies.
小題3:A pregnant elephant uses inaudible growls to           .
A．show the location where she is staying
B．a(chǎn)sk for help when she losses her way
C．scare away the enemy
D．let others know she will have a baby
小題4:What is the passage mainly about?
A．The elephants can speak like people.
B．The wild elephants’ ways to fight against enemies.
C．The “secret language” between elephants.
D．The special life of female elephants.

小題1:A

The home of the future won’t be completely different and we will be living in houses and flats just as we do today．But people will want to shape their homes to match their dreams．No two homes will be the same．People will be able to buy “house kits” containing a basic house structure, with movable walls, doors and windows．They will put together the different parts to create the home they want．
Many jobs that we do today will disappear, others will still exist but will change and new jobs will be created. Skilled workers such as builders, gardeners and electricians won’t disappear because machines can’t replace them. Teachers will still exist because students need human contact. But they will be using modern technology in class more and students will be working more from home. The medical technology revolution and space travel will create new jobs which we can only imagine today．
Space holidays will develop in the future, but these holidays won’t be for everyone because they won’t be cheap. Short space trips will develop first, then space hotels will orbit the earth where it will be possible to have a longer vacation. By the end of the next century, there will be holiday centres on the moon with leisure facilities for families．
Paper won’t exist in the future. Instead, there will be e-paper which people will be able to use over and over again. This will develop in order to save natural resources. E-newspapers and e-magazines will replace traditional newspapers and magazines and we will download information and news articles from the Internet every day onto our reuseable paper．
The laws of physics tell us that the earth is going to disappear some time in the future．This isn’t going to happen tomorrow but scientists predict that it will happen in five billion years when our sun explodes (爆炸)．We will have to explore the universe and find another home.

Since the 1990s, education has been required for all South Africans from age seven to fifteen. Last December, the government announced that 70% of students passed their final examination to finish high school. In 2008, the pass rate was about 63%. There have been increases each year since then.
Professor Shireen Motala says basic education is no longer a problem in South Africa. Most children stay in school until they are about sixteen. The problem is that large numbers of them leave without completing high school.
Students take an examination known as the “matric”(高考) in Grade Twelve. Professor Motala says, “Less than half of the children who started school in 2000 sat for the matric last year. Many dropped out of school, so only around 45% took the matric. And the worry is where those students actually go.” Those who drop out have to compete with better educated people for jobs.
Educational researchers also point to another problem. South African schools do not produce enough students with the skills for higher education in maths and science. Many schools are not well-equipped. Children do not see laboratories, and, as a result, their science marks are not very good. They do not have libraries at school. Also, many teachers do not have the skills or training to do their jobs.
In South Africa, a number of teachers were poorly trained before. Secondly, teachers have been confused by the many educational reform efforts in the last fifteen years. Finally, language differences in the classroom have not got as much attention as they should, which is a huge problem. Subjects such as maths and science are taught in English starting at about the age of ten. But South Africa has eleven official languages.
South Africa’s minister of basic education promises a number of improvements. Angie Motshega says teacher development efforts will focus on subject and content knowledge, making sure that the correct teachers are in the correct jobs.
小題1:From the first paragraph we can learn that ______.
A．South Africans are badly in need of education
B．South African teenagers do very well at school
C．the South African government takes education seriously
D．South African teenagers have become more clever
小題2:What is the real concern of Shireen Motala?
A．Something is wrong with the country’s basic education system.
B．Most children have to find a job at an early age.
C．The final exam is too difficult for most children.
D．Most children cannot complete high school until they are 16.
小題3:South African students perform poorly in science for all of the following reasons, EXCEPT ______.
A．they don’t work hard enough
B．their schools do not have laboratories
C．they cannot get help from libraries
D．there are not enough skilled teachers
小題4:With which of the following would Shireen Motala most probably agree?
A．Schools should focus more on maths and science than any other subject.
B．More educational reforms should be carried out in South African schools.
C．The more teachers teach maths and science, the better marks students may get.
D．More attention should be paid to language differences in maths and science classes.

Luo Gaoqi hopes to join the increasing number of Chinese students in the United States because he wants the experience of studying in a foreign land as it will help his future job at home. “I want to try Western education because people there think differently,” said the 21-year-old who is in his final year of undergraduate studies. “I also hope to meet friends from different cultures. The social connections may help in the future.”
The latest report from the US-based institute of International Education said China, for the first time, has become the top country of origin for international students in the United States.
For Yang Fan, a journalism student, said studying in the United States is a way to escape the competition for places in China’s top universities.
“Due to limited education resources, only about 60 percent of high school graduates in China enter college, and a much lower rate enters the top-level ones. “A foreign degree will definitely help when I seek a job in China,” Yang said.
Both Yang’s and Luo’s parents are supportive of them studying abroad. Neither of them is thinking of settling down in the United States after graduation.
“It is not realistic to do so. As a journalism student, there would be no advantage for me to work in the United States,” Yang said. “But in China, with a US degree and good English, I may stand out against other students who have only studied in China.”
China still needs to improve its environment for scientists and high-level talents, said Xiao Mingzheng, director of the Center for Human Resource Development and Management Research of Peking University, adding that, in particular, the country needs to improve its policies relating to research environments.
In June, the Chinese government published a plan concerning talent development for the next 10 years. In it, it has improved policies and increased budgets to attract talented students back home.
小題1:Why does Luo Gaoqi wants to study in a foreign land according to his words?
A．Because the people there are more intelligent.
B．Because the foreign countries are more developed.
C．Because he can make more friends there.
D．Because the culture there is different from that in China.
小題2:What do Guo Gaoqi and Yang Fan have in common?
A．Their major is the same, which is journalism.
B．Both of them want to go back to China after graduation.
C．Their parents are against their decision.
D．They are forced to study in a foreign land by their parents.
小題3:From the passage, we can infer that _______.
A．scientists and high-level talents need a better environment in China
B．the students abroad are unwilling to go back to China
C．China doesn’t need those people to come back to our country at all
D．we all need to go abroad to study and then serve our own country

I was telling my boy Sonny the story of the hare (兔子) and the tortoise (烏龜). At the end I said, “ Son, remember: Be slow and steady (鎮(zhèn)定的), and that will win the race. Don’t you think there’s something to learn from the tortoise?”
Sonny opened his eyes wide, “Do you mean next time when I’m entering for the 60-metre race I should wish that Billy, Tony and Sandy would all fall asleep halfway?”
I was shocked, “But the tortoise didn’t wish that the hare would fall asleep!”
“He must have wished that,” Sonny said, “Otherwise how could he be so foolish as to race with the hare? He knew very well the hare ran a hundred times faster than he himself did.”
“He didn’t have such a wish,” I insisted. “He won the race by perseverance (堅忍不拔的), by pushing on steadily.”
Sonny thought a while. “That’s a lie,” he said. “He won it because he was lucky. If the hare hadn’t happened to fall asleep, the tortoise would never have won the race. He could be as steady as you like, or a hundred times steadier, but he’d never have won the race. That’s for sure.”
I gave up. Today’s children are not like what we used to be. They’re just hopeless.
小題1:The writer argued (辯論)with his son because ______________.
A．he liked tortoises while his son liked hares
B．they disagreed about whether the tortoise was foolish

小題2:Sonny believed that the tortoise ______________.

B．took a risk (冒險) by agreeing to run a race
C．was not given a fair chance in the race
D．in fact did win the race luckily
小題3:Billy, Tony and Sandy must be_______________.
A．boys who were unknown to Sonny’s father
B．boys who Sonny has run races with before
C．boys who Sonny has never raced with before
D．boys who Sonny did not expect to race with again

In the computer age, most of us take a broadband（寬帶）Internet connection for granted. Whether cable or mobile broadband, today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly, and files download much faster than ten years ago. And the files are much bigger too.
There’s a catch, of course: You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.
Technology experts often talk about the “l(fā)ast mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in developing countries. Internet service providers, for their part, have been reluctant to provide access to sparsely (稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.
But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere.
Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables (光纖電纜) promise to bring extremely fast Internet connections to more users.
Still, the “l(fā)ast mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication (跡象), it may not be too long before an Internet connection simply follows you wherever you go.
小題1:The underlined part “a catch” (in Paragraph 2) probably means “_____”.
A．a(chǎn) rare challengeB．a(chǎn) desirable planC．a(chǎn)n efficient deviceD．a(chǎn) hidden problem
小題2:What can we know from the third paragraph?
A．Internet connection has not been popular in most cities.
B．Internet service providers care about rural（農(nóng)村的）customers.
C．Computer is popular in developing countries.
D．It is hard to bring Internet access to users in remote areas.
小題3:Paragraph 4 mainly tells us that technological advancements _____.
A．make TV and telephone available everywhere
B．bring great change to people’s everyday life
C．make it possible for more people to use the Internet
D．bring faster Internet connections to users
小題4:What may eventually settle the “l(fā)ast mile” problem?
A．The broadband connection’s getting faster.
B．More and more Internet users.
C．more and more Internet connections.
D．The rapid progress in cell phone technology.
