Last week my youngest son and I visited my father at his new home in Tucson, Arizona. He moved there a few years ago, and I was eager to see his now place and meet his friends.
My earliest memories of my father are a tall, handsome, successful man devoted to his work and family but uncomfortable with his children. As a child I loved him; as a school girl and young adult(成年人)I feared him and felt bitter about him. He seemed unhappy with me unless I got straight A’s and unhappy with my boy friends if their fathers were not as “successful” as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard.
On the first day of my visit, we went out with one of my father’s friends for lunch at an outdoor cafe. We walked along that afternoon, did some shopping, ate on the street table, and laughed over my son’s funny facial expressions. Gone was my father’s critical(挑剔的)air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around? What had held him back before?
The next day my dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him at that moment. After so many years, I’m at last seeing another side of my father. And in so doing, I’m delighted with my new friend. My dad, in his new home in Arizona, is back to me from where he was.
19.Why did the author feel bitter about her father as a young adult?
A．He was silent most of the time              B．He was too proud of himself
C．He did not love his children                D．He expected too much of her
20.When the author went out with her father on weekends, she would feel________.
A．nervous          B．sorry             C．tired             D．safe
21.What does the author think of her father after her visit to Tucson?
A．More critical B．More talkative C．Gentle and friendly D．Strict and hard-working
22.The underlined words “my new friend” in the last paragraph refer to________.
A．the author’s son B．the author’s father C．the friend of the author’s father D．the cafe owner

Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?
UBC Professor Simard explains how trees are much more complex(复杂的) than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true：trees survive through their co-operation and support, passing around necessary nutrition "depending on who needs it".
Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌)networks, making sure that all trees in the forest ecological system（生态系统） give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.
Simard talks about "mother trees", usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down "mother trees" with no awareness of these highly complex "tree societies" or the networks on which they feed, we are reducing the chances of survival for the entire forest.
"We didn't take any notice of it" Simard says sadly. "Dying trees move nutrition into the young trees before dying, but we never give them chance." If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.
23.The underlined sentence "the opposite is true" in Paragraph 2 probably means that trees         . 
A. compete for survival B. protect their own wealth
C. depend on each other D. provide support for dying trees
24."Mother trees" are extremely important because they________.
A. look the largest in size in the forest B. pass on nutrition to young trees
C. seem more likely to be cut down by humans D. know more about the complex "tree societies"
25.The underlined word "it" in the last paragraph refers to________.
A. how "tree societies" work B. how trees grow old
C. how forestry industry develops D. how young trees survive
26.What would be the best title for the passage?
A. Old Trees Communicate Like Humans B. Young Trees Are In Need Of Protection
C. Trees Are More Awesome(了不起) Than You Think D. Trees Benefit Our Society

When women sit together to watch a movie on TV, they usually talk simultaneously（同时的）about a variety of subjects, including children, men, careers and what’ s happening in their lives. When groups of men and women watch a movie together, the men usually end up telling the women to shut up. Men can either talk or watch the screen -- they can’ t do both -- and they don’ t understand that women can. Besides, women consider that the point of all getting together is to have a good time and develop relationships -- not just to sit there like couch potatoes staring at the screen.
During the ad breaks, a man often asks a woman to explain the plot and tell him where the relationship between the characters is going. He is unable, unlike women, to read the subtle（微妙的） body language signals that reveal how the characters are feeling emotionally. Since women originally spent their days with the other women and children in the group, they developed the ability to communicate successfully in order to maintain relationships. For a woman, speech continues to have such a clear purpose: to build relationships and make friends. For men, to talk is to relate the facts.
Men see the telephone as a communication tool for sending facts and information to other people, but a woman sees it as a means of bonding（亲密关系的形成）. A woman can spend two weeks on vacation with her girlfriend and, when she returns home, telephone the same girlfriend and talk for another two hours.
There is no convincing evidence that social conditioning, the fact that girls’ mothers talked to them more, is the reason why girls talk more than boys. Psychiatrist Dr Michael Lewis, author Social Behaviour and Language Acquisition, conducted experiments that found mothers talked to and looked at, baby girls more often than baby boys. Scientific evidence shows parents respond the brain bias（偏好） of their children. Since a girl’ s brain is better organized to send and receive speech, we therefore talk to them more. Consequently, mothers who try to talk to their sons are usually pointed to receive only short grunts in reply.
27. While watching TV with others, women usually talk a lot because they________.       
A．are afraid of awkward silence with their families and friends
B．can both talk and watch the screen at the same time
C．think they can have a good time and develop relationships
D．have to explain the plot and body language to their husbands
28. After a vacation with her girlfriend, a woman would talk to her again on the phone for hours in order to________.             .
A．experience the happy time again
B．keep a close tie with her
C．recommend her a new scenic spot
D．remind her of something forgotten
29. What does the author want to tell us most?
A．Women’ s brains are better organized for language and communication
B．Women love to talk because they are more sociable than men.
C．Men do not like talking because they rely more on facts.
D．Social conditioning is not the reason why women love talking.
30. Which of the following would be the best title for the passage？
A．Women Are Socially Trained to Talk
B．Talking Maintains Relationships
C．Women Love to Talk
D．Men Talk Differently from Women.

Muzak /
The next time you go into a bank, a store, or a supermarket, stop and listen. What do you hear? __31__It's similar to the music you listen to, but it's not exactly the same. That's because this music was especially designed to relax you, or to give you extra energy. Sometimes you don't even realize the music is playing, but you react to the music anyway.
Quiet background music used to be called "elevator (电梯) music" because we often heard it in elevators. But lately we hear it in more and more places, and it has a new name "Muzak". About one-third of the people in America listen to "Muzak" everyday. The music plays for 15 minutes at a time, with short pauses in between. It is always more lively between ten and eleven in the morning, and between three and four in the afternoon, when people are more tired.__32__
If you listen to Muzak carefully, you will probably recognize the names of many of the songs. Some musicians or songwriters don't want their songs to be used as Muzak, but others are happy when their songs are chosen. Why? __33__
Music is often played in public places because it is designed to make people feel less lonely when they are in an airport or a hotel. It has been proven that Muzak does what it is designed to do. Tired office workers suddenly have more energy when they hear the pleasant sound of Muzak in the background. __34__Supermarket shoppers buy 38 percent more groceries.
__35__. They say it's boring to hear the same songs all the time. But other people enjoy hearing Muzak in public places. They say it helps them relax and feel calm. One way or another, Muzak affects everyone. Some farmers even say their cows give more milk when they hear Muzak!
A. Some people don't like Muzak.
B. The music gives them extra energy.
C. Music is playing in the background.
D. Factory workers produce 13 percent more.
E. Muzak tends to help people understand music better.
F. They get as much as $4 million a year if their songs are used.
G. Muzak is played in most of the big supermarkets in the world.

Dear Peter,
Glad to hear that you are going to take a trip to China this August. Welcome! As I know, you are always interested in Chinese culture and want to learn some Chinese.Therefore, I suggest that you choose Chinese daily dialogues as a start, like greeting people, asking for directions and bargaining for souvenirs, which canhelp you a lot during your trip. 
Learning a foreign language needs great efforts. Apparently, I'd like to be your Teacher and send you an e-book with my teaching schedule later. Besides, Let's have an online class over the Internet every weekend, through which I will try my best to make your learning easier and surely you can speak some fluent Chinesebefore your arrival.
Looking forward to your early reply.
                                                                    Yours,
                                                                    Li Hua
