【題目】 What would the world be like if cars could drive themselves? Imagine seeing an empty car passing by on its way to pick up its owner, or a car full of passengers who are reading, listening to music or even sleeping. But none of them are worried about the road ahead.

Well, all of this could be the future of driving. There are several companies, including Google, working on driverless (無(wú)人駕駛) cars. These cars are now in testing (測(cè)試). If the tests are successful, these self-driving cars can be used very soon. But how is it possible for a car to drive itself?

Some cars already have many features (特點(diǎn)) allowing them to take the place of drivers during certain situations. Some features include cars being able to park themselves, or slow down when they discover objects close by. They can also control the speed (速度) if there are dangerous conditions, such as snow or wet roads.

Other features have also changed the way drivers deal with some situations. Scientists believe, with the help of wireless signals (無(wú)線信號(hào)), cameras and GPS, making a safe self-driving car can be possible. The cause of serious road accidents is usually careless driving or dangerous conditions. The self-driving car may be able to prevent (阻止) these. However, some people do not like the idea. American lawyer White Drake, for example, doesn’t believe these cars are safe. He thinks that technology can also make mistakes.

【1】Driverless cars ________.

A.cost more than normal carB.make the road saferC.can’t control the speed D.are still in testing

【2】From the passage, we know some cars already have the ability (能力) to ________.

A.park themselvesB.pick up their owners

C.prevent all the dangerous situationsD.refuse careless drivers

【3】According to scientists, safe driverless cars can work well with the help of ________.

A.American lawyersB.excellent drivers

C.wireless signals, cameras and GPSD.scientists and passengers

【4】What’s the passage mainly talked about?

A.The successful tests of driverless cars.

B.Driverless cars will take the place of normal cars soon.

C.To introduce the advantages (優(yōu)點(diǎn)) and disadvantages (缺點(diǎn)) of driverless cars.

D.The future of driverless cars.

【題目】 What do you think about when you think of a zoo? Small cages? Bars like those in prisons? These images might be common in people’s mind, which serve as arguments for the people who do not like zoos, as historically, traditional zoos kept animals with a very limited focus on conservation(protection of natural things or education, However, a sort of evolution (改革;進(jìn)化) has occurred.

Most zoos today, especially those in the Association of Zoos and Aquariums (AZA), an international organization whose members are leading zoos and aquariums, provide spacious and natural space for their animals and worked hard to keep them mentally and physically stimulated. More importantly, modern zoos not only take much better care of the animals they keep, but also engage with the protection of animals in the wild.

As the human population increases, our impact on the environment has been deadly harmful to wildlife and wild spaces. Things like climate change and severe habitat destruction are causing species to go extinct at unnatural rates. Some scientists estimate we are currently experiencing the sixth mass extinction (滅絕) in the history of life on earth. As a consoling (令人安慰的) part out of all griefs, many zoos serve as important safe-holds for endangered species populations, and in cases like that of the California Condor, captive breeding programs in AZA, which kept animals in zoos proved to be important in bringing species back from extinction. Besides, AZA, including many zoos, also fund over 2,500 conservation projects, donating 160 million dollars every year to protecting species in the wild.

The conservation impact that zoos have goes even further than direct conservation action and financial support for fieldwork. In a time when people spend less and less time outdoors, zoos serve as a place to teach children and remind adults that wildlife and wild spaces still exist, and that our society holds the future of these species’ survival in our hands.

________________________. While I am only 18, I have spent the last six years volunteering with wildlife conservation organizations. As a volunteer at the Santa Barbara Zoo, I stood outside of the Amur Leopard exhibit and educated guests about these critically endangered big cats. I saw the way that live animals can spark people’s curiosity and inspire them to love and protect nature. Earlier this year, I had the opportunity to attend the AZA’s Legislative Conference in Washington DC, where I got the opportunity to see how zoos support conservation efforts in the wild. Cheetah Conservation Fund in Namibia is an organization dedicated (致力于) to saving the cheetah in the wild, but it relies heavily on support from zoos. Many zoos donate large amounts of money to CCF, but they also contribute to CCF’s mission by connecting people across the United States with cheetahs, and the issues they face in the wild.

Zoos can be controversial institutions; however, both opponents of traditional zoos and those who support modern zoos have more in common than one might think. Both groups are extremely motivated because they care so deeply about animals, their welfare, and their long-term survival on our planet. I encourage you to consider both sides of this issue and learn more about all of the conservation work zoos do, and the world-class care animals in AZA receive before determining where you stand on this issue.

【1】Images like small cages are mentioned in Paragraph 1 to explain ________.

A.why there must be an evolution of zoos

B.how much people misunderstand the zoos

C.why some people are against traditional zoos

D.how well the modern zoos are treating animals

【2】According to Paragraph 3, what do captive breeding programs do?

A.They are conservation projects donating to AZA.

B.They protect the wild habitat of endangered animal.

C.They keep endangered animals to save them from extinction.

D.They set up missions of animal protection for AZA every year.

【3】Which sentence serves best as the topic sentence of Paragraph 5?

A.However, there is still much that zoos should have done.

B.I have gotten to see many of the positive aspects of zoos up close.

C.Yet what I have personally experienced might explain why zoos have caused so much disagreement.

D.The misunderstanding of zoos, unfortunately, is still widespread, and some people are blind to the contributions zoos have made.

【4】What is TRUE according to the article?

A.Zoos in Namibia heavily reply on the Cheetah Conservation Fund

B.Traditional zoos only paid attention to conservation but no education.

C.Modern zoos bear responsibility for the animals they keep and those in the wild.

D.With the increase of human population, a huge species extinction in history is on.

【5】Which could be the best title for the article?

A.Traditional Zoos: Harmful to Wildlife

B.AZA: A Consoling Part out of All Griefs

C.Evolution of Zoos: More Changes in Need

D.Modern Zoos: Dedicated to Saving the Wildlife
