Robots performing tasks according to a predetermined set of instructions are nothing new.But robots able to learn how to cook by watching videos are a completely different approach, which is conducted by a group of researchers at the University of Maryland.

If you have posted a video of your favorite recipe on the popular website YouTube, chances are that it will be used by a robot.University of Maryland's professor Yiannis Aloimonos, leader of the group, said “There exists a large amount of video information on the Internet that our robots can capitalize_on.”

“At present, the videos are fed electronically，”said research scientist Cornelia Fermuller.“Originally, we took our own videos, our cameras looking at us doing the cooking，”she explained.“And, as the robot advances, it reacts to good quality videos.And it will react to even lower quality homemade videos.”

So far, the robot named Julia can make a simple salad by breaking each task into basic parts, such as grasping a spoon, bringing it to the bowl, stirring the salad and observing the results.

But why teach a robot how to understand a video when it can easily follow a fixed program？Aloimonos believes predetermined instructions lack flexibility.He thinks one of the problems is how to make the robot understand and use what it learns during a certain task, the socalled feedback (反饋意見); another is the introduction of language.

“I believe it will take quite some time before the robots are able to understand metaphorical (比喻性的) laguage，”he added.“But，” he said，“we don't need that to create a new world where the robots will be working for us.”

【1】The underlined phrase “capitalize on” in Paragraph 2 probably can be replaced by ________.

A．take hold of B．make use of

C．keep track of D．catch sight of

【2】Aloimonos probably agrees that at present the robot ________.

A．can not fully digest what it learns

B．can not make a simple salad

C．can follow homemade videos

D．can understand metaphorical language

【3】Robots are taught to understand a video mainly because ________.

A．they can easily follow fixed programs

B．they are smart enough to learn cooking

C．cooking videos are more interesting to watch

D．predetermined instructions are not flexible

【4】Which of the following might best serve as the title of the passage?

A．Robots Creating a New World

B．Robots Making Cooking Videos

C．Robots Learning to Cook by Watching Videos

D．Robots Performing Tasks by Following Instructions

【答案】

【1】B

【2】A

【3】D

【4】C

【解析】

試題分析：

【1】詞義猜測題。由第二段的第一句“If you have posted ...used by a robot.”可知，機(jī)器人能利用網(wǎng)上大量的視頻信息。結(jié)合第二段的最后一句可知，capitalize on應(yīng)與“make use of”意思相近，因此選擇B項。

【2】推理判斷題。根據(jù)最后一段Aloimonos的話可知，該機(jī)器人目前還不能理解比喻性的語言。根據(jù)倒數(shù)第二段的最后一句可推知，Aloimonos可能認(rèn)為目前該機(jī)器人還不能完全消化它學(xué)的東西，應(yīng)選擇A項。

【3】細(xì)節(jié)理解題。根據(jù)倒數(shù)第二段的前兩句可知，教機(jī)器人理解視頻是因為預(yù)定指令不夠靈活，應(yīng)選擇D項。

【4】標(biāo)題歸納題。文章主要介紹了通過觀看視頻學(xué)做飯的機(jī)器人，因此C項是最佳標(biāo)題。

Dear Dr. Health

I am very overweight. Since people often laugh to me behind my back when I ride the underground or going for a walk, I am embarrassing and do not like going out any more. Certainly, I do not feel comfortably going to the gym to work out. Instead, I prefer to exercise at home, and it seemed that I am always going on a diet. But, no matter what I do, my efforts to lose weight always end in failure.

As a matter of the fact, my friends say that I am an attractive girl just the way I am, and that I should not worry at all about my waist or my figures. However, I do worry that my weight might damage my health. I’m not sure whether I should take weight-loss pills. There are news about a Canadian actress which suffered liver failure because of taking those pills.

What do you think I should do?

Best wishes

Guo XiLin

【題目】閱讀理解。

The term “smog” was first used in London during the early 1900's to describe the combination of smoke and fog. What we typically call “smog” today is a mixture of pollutants but is primarily made up of groundlevel ozone (臭氧)．

Ozone can be beneficial or harmful depending on where it stays. The ozone staying high above the Earth protects human health and the environment, but groundlevel ozone is responsible for the choking, coughing, and painful eyes associated with smog. The ozone in smog also prevents plants growth and can cause widespread damage to crops and forest.

Major smog occurrences often are linked to heavy motor vehicle traffic, high temperatures, sunshine, and calm winds. Weather and geography affect the position and severity of smog. Because temperature regulates the length of time it takes for smog to form, smog can form faster and be more severe on a hot and sunny day. When warm air stays near the ground instead of rising and winds are calm, smog may stay trapped over your city for days. As traffic and other sources add more pollutants to the air, the smog gets worse. Smog is often more severe away from the pollution sources because the chemical reactions that cause smog occur in the atmosphere while the reacting chemicals are being moved by the wind.

Smog is a visible example of air pollution. You can look into the distance during the day to see how much smog there is in the air. span>In addition, most cities measure the concentrations of pollutants in the air and report the results to the public.

Environmental Protection Agency sets national standards for pollutants. Areas that fail to meet the standards for at least one air pollutant are called “nonattainment (不達(dá)標(biāo)) areas”. New measures are being taken by local governments across the country to reduce air pollution in nonattainment areas. These include: banning charcoal barbecues and wood burning in stoves or fireplaces when pollution levels are high; developing programs to encourage carpooling and voluntary “ozone actions”； limiting traffic in overcrowded areas; expanding or improving public transportation systems; requiring employers to contribute to employee public transportation costs; assessing “smog fees” on cars according to the number of miles driven and vehicle emissions (排放) produced; and even buying and breaking up older “superdirty” cars.

【1】According to the passage, groundlevel ozone can______.

A．damage the environment

B．benefit human health

C．protect crops and forest

D．limit the spread of smog

【2】Which of the following is TRUE according to the passage?

A．Air quality is better in time of calm wind.

B．Smog is more severe near pollution sources.

C．It takes more time for smog to form in hot weather.

D．Chemical reactions occur in the moving air and cause smog.

【3】Which indication shows more exact the air is poor?

A．Heavy motor vehicle traffic in big cities.

B．Widespread damage of crops and forest.

C．Clear outlines of hills in the distance.

D．High concentrations of pollutants in the air.

【4】What is included in the measures being taken by the local governments?

A．Uncondtional banning of wood burning.

B．Encouraging carpooling and public transportation.

C．Charging all the vehicles more “smog fees”．

D．Buying new cars to replace superdirty old cars.

Dear Mum and Dad

We're having a wonderful time in Australia. There is so much to see that it is impossible for me to tell you everything. During past three days, we've travelled a lot around Sydney. We went to the zoo, on where we saw many animals that can only be found in Australia. We spent some time relaxing in the sunshine at the beach, but we went to Pitt Street and wander around for a bit while we did some shopping. Though I would like to spend more time here, the locally guide told us that we will fly to Cairns tomorrow. It's said that word cannot describe the beauty of the ocean near Cairns. Now everybody is busy packed so that we will not lose time when we set off. This time tomorrow we will be enjoying the ocean near Cairns. I can't wait!

Because I have much more to tell you, I must go to bed now so that I can get up early and get to the airport on time. Please send my best wishes to Granny and tell she that I am coming back soon.

Love

Robert

【題目】閱讀理解。

Where should an adventurous tourist go? After you've done sightseeing in London, shopping in New York, tasted the local food in Paris, and danced to your heart's content at the Brazilian Carnival, where else can you go? What exotic (異國風(fēng)情的) tourist destination awaits you?

Well, Antarctica sounds like the holiday of a lifetime! It's considered the last great wilderness on Earth. Just a few scientists in research stations share the icy landscape with penguins and other animals which can cope with the low temperatures.

Tourism began in Antarctica in the 1950s and it's still a small scale. About 37,000 tourists are expected there this season, but many won't even leave the boat.

The BBC's Juliet Rix visited the frozen continent and asked herself if she should be there at all, causing potential problems to such a sensitive environment. Her tour guide admitted that all visitors leave footprints and they all go to the same place, the accessible coastline, which is also where the penguins and seals go to breed.

But some people believe that if carefully controlled, tourism can be good for Antarctica. It has no native population and it needs advocates. Visitors to the icy continent might be ready to support and even to fund its preservation. And they're likely to engage in the discussion about global warming, which has led to the melting of glaciers.

According to Rix, guidelines are followed when you're about to set foot in Antarctica and tourists have to disinfect (為……消毒) their boots to make sure no alien species are introduced.

And once on land, there's no eating or smoking. Rocks, bone fragments — nothing should be taken as a souvenir and nothing should be left behind. Tourists fortunate enough to visit Antarctica must be aware that this is not their home and keep their fingers crossed that future generations will also be able to enjoy such breathtaking views.

【1】According to the second paragraph, we can learn that ________.

A．Antarctica has become the best place for people to travel

B．only scientists can be allowed to go to Antarctica

C．Antarctica is less affected by human activities

D．no animals can survive in Antarctica except penguins

【2】Juliet Rix's travel in Antarctica mentioned in the fourth paragraph indicates that ________.

A．governments should take measures to stop tourists from going to Antarctica

B．whether tourists should go to Antarctica or not should be considered carefully

C．the animals' habitat in Antarctica has been seriously affected by tourism

D．only journalists begin to pay attention to the environmental protection in Antarctica

【3】Which of the following statements is TRUE according to Rix?

A．Tourists can eat and smoke in Antarctica.

B．Tourists can take something they like from Antarctica.

C．Tourists can throw away something they don't need in Antarctica.

D．Tourists can enjoy the beautiful scenery in Antarctica.

【4】Which of the following is the best title of this passage?

A．Why can't tourists go to Antarctica?

B．How can tourists go to Antarctica?

C．Should tourists go to Antarctica?

D．Are tourists allowed to go to Antarctica?
