As heart of the Renainssance, Florence has long been one of the most attractive spots in Europe — So much to see, so little time. To help you plan your sightseeing, I’ve listed my ideal itineraries (旅行计划), whether you’re going for one day, two days or more .
    Florence deserves at least one well-organized day: see the Accademia (David), tour the Uffizi Gallery (Renaissance art), visit the underrated Bargello (best statues), and do my Renaissance Walk. Art lovers will want to chisel out another day of their itinerary for the many other cultural treasures.
Florence in Two or More Days
Day 1
8:30   Accademia (David) — with a reservation.
10:00   Museum of San Marco (art by Fra Angelico).

16:00   Visit Duomo interior and/or the Baptistery.

You have two easy options for skipping lines: buy a Firenze Card or make reservations.

    There are two types of people in the world. Although they have an equal degree of health and wealth and other comforts of life, one becomes happy, while the other becomes unhappy. This arises from the different ways in which they consider things, persons and events and the resulting effects upon their minds.

    People who are happy fix their attention on the convenience of things. They enjoy all cheerful things. Those who are unhappy think and speak only of unpleasant things. Through their remarks, they sour the pleasure of society, offend many people, and make themselves disagreeable everywhere. If this turn of mind is founded in nature, such unhappy people should be pitied. The intention of criticizing and being disliked is perhaps taken up by imitation（模仿）. It grows into a habit, unknown to its possessors. The habit may be strong, but it can be cured when those who have it realize its bad effects.

    Although this attitude is mainly an act of the imagination, it has serious results since it brings on deep sorrow and bad luck. If such people aim at getting some advantages in social position or fortune, nobody wishes them success. Nor will anyone speak a word in favor of their hopes. If they are criticized, no one will defend or excuse them, and many will join in criticizing their wrong doings. So they should change this bad habit and stop worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact with them. Otherwise, they will have a disagreeable time, especially when someone becomes mixed up in their quarrels.

12. How does the writer tell the happy from the unhappy?

A. According to their attitudes to the same thing.      B. According to their wealth.

C. According to their habits.            D. According to their degree of health.  

13. The phrase “sour the pleasure of society” probably means “________”.

 A. enjoy the pleasure of life       B. have a good attitude towards social life 

C. make others unhappy           D. tend to scold others openly             

14. If such unhappy people insist on keeping the habit, the author suggests that people should ________.

A. show no respect for them         B. not have any communication with them        

C. persuade them to recognize the bad effects of their habits

D. quarrel with them until they realize their mistakes            

15. In this passage, the writer mainly ________.

A. laughs at unhappy people   B. suggests ways to help unhappy people    

   C. describes two types of people    D. tells people how to be happy in life         

  Written in the first chapter of the book Pride and Prejudice is an extraordinary sentence of which even a person who has had only a brief look upon the book will not fail to receive a deep impression ---It is a truth universally acknowledged that a single man in possession of a good fortune must be in want of a wife. In terms of Sherlock Holmes, we’d better alter the sentence into “It is a fact universally accepted by readers throughout the world that an excellent book in possession of our famous detective Sherlock Holmes is undoubtedly a masterpiece of all times.” Perhaps this is one of the most obvious explanations for the unrivaled popularity of “Holmes series” in the field of detective stories. Overwhelmed by the recommendations provided by my friends, I decided to take a look on this Sherlock Holmes and the Duke’s Son originally published by Oxford University Press.

　　As a whole, this book is about a case concerning the Duke’s missing son. Arthur, the Duke’s son, was found out in a certain morning to have disappeared, accompanied with which was also the disappearance of the German teacher. The school master Dr. Huxtable then turned to the famous detective of the time Sherlock Holmes for help. Realizing how tough and important the case is, Holmes immediately made up his mind to accept the case and followed Dr. Huxtable back to Mackleton by train. Having formed a rough idea about the whole matter, Holmes probed into the case immediately and had a careful investigation of the entire area shortly after the arrival, during the process of which he discovered the body of the German teacher Heidegger. Finally, primarily due to his prominent ability as a detective, he managed to unravel the mystery.

　　Having once started reading this fiction, I was completely immersed in the mysterious story. At the beginning, unlike other detective stories, this story first delineates the client’s strange behavior at length to indicate the severity of the incident in order to attract the readers to continue reading it. As is known to all, vivid depiction is essential to detective stories as it makes the story more authentic and attractive. Therefore, trying to present a “real world” to his readership, Sir Arthur Conan Doyle, author of the original “Holmes series”, has skillfully arranged the plots of the whole story from the perspective of Dr. Watson, a friend of Homes’. In this way, he elaborately (精心)depicted every scene and character in the book, Apart from the special start, the ending of the whole story, being dramatic but reasonable, is certainly an outstanding one. After all, except the author himself, who knows that the Duke’s seemingly ordinary secretary is in fact the Duke’s bastard(私生子)? In addition, who knows that the Duke actually has already been acquainted with the whole thing before Holmes solves this complicated problem? Yet, surprising as it is, this ending seems so natural that it fits all the plots of the story perfectly well. Closing my eyes, I can even “see” the story happening just like watching a film.

　　As far as I am concerned, nothing is more admirable and surprising in the hero Sherlock Homes than his profound knowledge which has certainly assisted him a lot when he was studying the case. Take the bicycle tyres for instance, Holmes is capable of recognizing 42 different varieties of bicycle tyres. Except for his illimitable knowledge, Holmes also specializes in arranging the facts in order and then finding the fact leading him to a great discovery or even the truth itself. In this case, after getting rid of unrelated facts, Sherlock Homes eventually grasped the clue and discovered the amazing fact.

   Needless to say, as a world-renowned masterpiece, Sherlock Holmes and the Duke’s Son has attracted and is still charming numerous readers from all corners of the world and people from all walks of life. The “Holmes series” has already set up a standard against which all the following detective fictions are measured. Sherlock Holmes, beyond all doubt, has been a name firmly rooted in people’s memories. Although Dr. Watson’s closing The Case Book of Sherlock Holmes in 1927 was a great pity to the readers, the discontinuance of the entire “Holmes series” may have actually added to the legendary stature of Sherlock Holmes.

91. Why does the author mention the book Pride and Prejudice?

   A. To show his/her impression on it

   B. To change a sentence in it to evaluate the Holmes series

   C. To quote a sentence to directly illustrate its impressiveness

   D. To state the reason why he/she began reading Sherlock Holmes and the Duck’s son

92. Many factors contribute to the author’s positive attitude toward the book EXCEPT that __________.

   A. the detailed description of a client’s strange behavior arouses the readers’ interest

   B. the plots are well laid out and all scenes and characters are artfully presented

   C. the book is even adapted into a film and the author really enjoys watching it

   D. its ending is so surprising that it makes the author deeply impressed.

93. What kind of a person is Sherlock Holmes according to the passage?

   A. Knowledgeable            B. Arbitrary          C. Mysterious         D. Courageous

94. How is the passage organized?

(p=paragraph)

95. What’s the passage mainly about?

   A. It mainly introduces the plots of the book Sherlock Holmes and the Duck’s son

   B. It’s mainly about the author’s attitude towards Sherlock Holmes

   C. It’s mainly about the thoughts of the author after reading Sherlock Holmes and the Duck’s son

   D. It’s mainly a comparison between the book Pride and Prejudice and the Holmes series

Small talk is a good way to make friends. If you travel to other countries or have friends from abroad, do you know how to use small talk to make conversation?

     In Britain, the best topic is the weather. British weather is changing all the time.       16     

    Besides weather, it’s good to talk about gardens with British. You could say “Those roses look really beautiful, don’t they?”        17      .So it’s also nice to start with “What a lovely dog! What is his name?”

    In America, people like to talk about sports news ,such as American football and basketball.      18      So you might say “It’s a nice shirt! Where did you get it?” Weather is a safe topic there, too.

           19     Don’t ask people “How old are you?” Never ask: “How much money do you make?”It makes people uncomfortable. Don’t ask strangers weather they are married.      20     There are others in our daily life.

A. You can start chatting by saying “It’s a lovely day today, isn’t it?”

B. There are also a lot of topics to avoid during small talk.

C. Friends are important to us all, but how to make friends is a problem.

D. Americans also talk about clothes.

AB. Politics or religion is not a good topic.

AC. English people love their pets.

AD. Only a few topics are not used for small talk.

When Mrs. Gabica went out of the teaching building after finishing the last class in her career, she saw a lot of pupils on the playground, wearing uniform clothing, like an activity of celebrating the coming Teachers’ Day. Before realizing what happened, she was presented a bunch of flowers by two pupils and led to the playground. Then the loving words “Thank you. Wish you health and peace!” from the broadcast wafted (飘荡) over the playground. As she stood in the middle of the playground, teachers switched on an iPod and around 350 schoolchildren, aged three to seven, broke into a specially designed formation. The teacher was moved to tears when pupils broke into a flash mob dance to mark her final day after 25 years.

In fact, taking her health into account, the leadership of the school has advised Mrs. Gabica to retire from school many times, but she refused firmly. Despite having diabetes in 2011, suffering from pain after being hit by a car in 2014 and even having a sick son to care for many years, Mrs. Gabica persevered in teaching and staying with her pupils. If she did not come to the age for retirement, she would be bound to stay with her pupils because she has a deep love for her career. Her pupils spent three weeks learning their routine to The Lion King’s He Lives in You, which was one of the music lover’s favorites, being careful not to let their secret out of the bag. Obviously, Mrs. Gabica wasn’t prepared for such a memorable send-off.

 The headteacher Luke Mansfield said，“It was a wonderful way to celebrate all that Mrs. Gabica has done for the school. Since posting it we have had so many messages from former pupils who remember their happy times in her class. It’s a testament to the hard work and I think she deserves everything that she receives.”

    A. has achieved many honors in her career

    B. was extremely welcomed by teachers and pupils

D. Mrs. Gabica is an experienced music teacher.

Nuclear power's(核能的) danger to health, safety, and even life itself can be described in one word; radiation(辐射).

Nuclear radiation has a certain mystery about it, partly because it cannot be detected (探测) by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.

At very high levels, radiation can kill an animal or human being outright by killing masses of cells (细胞) in important organs (器官). But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be significant. This is the case when only a few cells are hit, and if they are killed outright. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.

This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated(放射治疗) and feel fine, then die of cancer five, ten, or twenty years later as a result. Or a child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.

Radiation can hurt us. We must know the truth.
