Can dogs and cats live in perfect harmony in the same home? People who are thinking about adopting a dog as a friend for their cats are worried that they will fight. A recent research has found a new secret of success. According to the study, if the cat is adopted before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly likely that the two pets will get alongswimmingly. Two?thirds of the homes interviewed reported a positive relationship between their cat and dog.

However, it wasn't all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while fighting were observed in 10% of the homes. One reason for this is probably that some of their body signals were just opposite. For example, when a cat turns its head away it signals attacking, while a dog doing the same signals giving in.

In homes with cats and dogs living peacefully, researchers observed a surprising behavior. They are learning how to talk each other's language. It is a surprise that cats can learn how to talk “dog”，and dogs can learn how to talk “cat”．

What's interesting is that both cats and dogs have appeared to develop their intelligence. They can learn to read each other's body signals, suggesting that the two may have more in common than we previously thought. Once familiar with each other's presence and body language, cats and dogs can play together, greet each other nose to nose, and enjoy sleeping together on the sofa. They can easily share the same water bowl and in some cases groom (梳理) each other.

The meaning of this research on cats and dogs may go beyond pets—to people who don't get along, including neighbors, colleagues at work, and even world superpowers. If cats and dogs can learn to get along, surely people have a good chance.

From;Robert Renfield robertyaho@nemo.com

To:Citizens' Bank aas@citizensbank.net

Subject;An Inquiry of the Alert Service

Good afternoon,

I am writing to request more information on your new Automated Alert Service,as advertised on your Website.I have had both personal and commercial accounts with Citizens' Bank for many years.Often,I find it necessary to move money between accounts.Because of this,it is vital that I keep a close eye on the cash flow of all of my accounts,to assure that their balances stay above the required minimums.Therefore,I have been searching for an economical means of keeping better track of my finances.I was considering purchasing software for this purpose,but I think that your new service might be a convenient alternative.

My first question concerns the timeliness of the notifications.When you say “instantly,” does that relate only to banking hours? For example,if my wife were to use our debit card (借記卡）on a Sunday afternoon to make a transfer (轉(zhuǎn)賬）at an ATM,would I be informed via email instantly or on Monday morning? My second question is in regard to the information available in this service.Is it possible to be aware of any information in my monthly bank statement,such as interest on my savings account? Finally,I would like to know the cost of this service.

When The New Republic magazine predicted who would win the 2016 Nobel Prize in literature on Oct 6, it said: “Not Bob Dylan. That’s for sure.”

But the award came as a surprise to many. On Oct 13, the famous US musician was named the Nobel laureate by the Swedish Academy. He has “created new poetic expressions within the great American song tradition", according to the organization.

Although Dylan, 75, is not really thought to be a literary（文學(xué)的） writer, he has given the world a lot of creative work over 50 years, especially when it comes to his folk songs.

In his 1985 album Biograph, Dylan wrote about the appeal(魅力) of folk music to him. Rock songs “weren’t serious enough or didn’t reflect（反映） life in a realistic way", according to Dylan. But folk, was “a more serious type of thing. The songs are filled with more sadness; more joy …much deeper feelings".

Dylan’s music and lyrics spoke to many people during the 1960s. His lyrics were often about great political issues, such as the civil rights movement. The 1960s were a time of change when the young were making sure that their voices were heard. The idea is most famously expressed in Dylan's The Times They Are a -Changing (1964), which warns the world, “You better start swimming or you'll sink（下沉） like a stone. For the times they are a-changing!”

There were complaints that a literary prize had been given to a singer. But ancient “Greek poets Homer and Sappho wrote poetic works that were meant to be listened to, that were meant to be performed, often with instruments — and it’s the same way with Dylan", the Swedish Academy’s permanent secretary Sara Danius told CNN.

It could even be said that giving the important prize to Dylan has brought back an old literary tradition. The millions whose lives Dylan’s words and music have changed will surely welcome the award.

1.Dylan found folk music attractive because ________.

A. it brought joy to people

B. it reflected life on a much deeper level

C. it could be used to express feelings freely

D. it needed more creativity than other types of music

2.Which of the following statements is TRUE about Dylan according to the article?

A. He never thought that he would win the Nobel Prize.

B. All of his influential works were created in the 1960s.

C. His songs expressed people’s feelings well during the 1960s.

D. His fans were mostly young people who were active in political movements.

3.According to the last two paragraphs, ________.

A. lyrics can be seen as a literary form

B. a literary prize should not be given to a singer

C. Dylan’s works were inspired by Greek poets

D. Dylan won the award because he influenced many song-writers

4.What’s the author’s attitude toward giving Bob Dylan the 2016 Nobel Prize in literature?

A. Unconcerned. B. Objective. C. Doubtful. D. Supportive.

Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses（球場(chǎng)） in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.

There are many environment-friendly sports. Power walking is one of them that you could take up today. You don't need any special equipment except a good pair of shoes; and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be "green gyms". They are better replacements（代替物）for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

1.Which of the following is the author most probably in favor of?

A. Playing basketball in a gym.

B. Motor racing in the desert.

C. Cycling around a lake.

D. Swimming in a sports center.

2.What do we know about golf from the passage?

A. It is popular in Portugal and Spain.

B. It needs water and electricity to keep its courses green.

C. It pollutes the earth with chemicals and wastes.

D. It causes water shortages around the world.

3.The author uses power walking as an example mainly because ________.

A. it uses fewer resources

B. it improves our health

C. it is an outdoor sport

D. it is recommended by experts

4.The author writes the passage to ________.

A. show us the function of major sports

B. encourage us to go in for green sports

C. discuss the major influence of popular sports

D. introduce different types of environment-friendly sports

Many of you are studying hard because you have to compete with many others in the upcoming national college entrance exam. But it may not occur to you that one of your competitors is a robot. An artificial intelligence(AI) robot will take part in the 2017 National College Entrance Exam, reported China Daily.

“The robot will sit three exams: math, Chinese, and a comprehensive test of liberal arts (文科), which includes history, politics and geography,” Lin Hui, CEO of an AI company in Chengdu. Like the others who take the exam, the robot will have to finish the tests in the given time. But instead of taking exams together with other students, the robot will take its exams in a closed room without anyone else present, except for proctors(監(jiān)考人) and a notary(公證人). It is expected to be totally disconnected from the Internet and solve the problems with its AI program.

It’s believed that Chinese and the test of its liberal arts skills, rather than its math skills, will give the robot its biggest challenges. Questions in math are objective with specific answers, while in the other test subjects there are some subjective questions that test skills such as reading comprehension and essay writing.

The robot aims to be enrolled in one of the first-class Chinese universities in 2017, and then try to get into the more famous universities of Tsinghua or Peking University in 2020.

1.The author wrote the passage in order to ________.

A. lay more burden on Grade 3 students

B. inform readers of the explosive news

C. introduce the function of the robot

D. predict what robots will do in the future

2.What’s the main idea of the second paragraph?
