Big things were happening in my life the summer after I turned 13. In the middle of that summer, my parents shook my whole world and turned it upside down when they told me they were getting a divorce(离婚). I couldn’t believe that our family was going to break up. Though I always knew my parents weren’t very happy and they often fought, I still wanted my family to stay the same.
My life changed a lot after the divorce. My mother and I moved into a small apartment across town, while my father and brother, Bill, stayed in our house. I now became a visitor whenever I went to see my dad and Bill on
weekends. And later I had my soon-to-be stepfather, Dan, whom I showed no interest in. I was clearly depressed, especially after Dan and my mother married and I realized that there was no way that things could changed back to the way they were.
Even though I resisted all Dan’s attempts(努力) to get to know me and wasn’t very nice to him, he never gave up on me. Gradually, I began to believe in him. I realized that we actually had some thing in common especially when it came to movies and TV shows. We spent a lot of time together hanging out and watching TV. That gave us a chance to talk and get to know each other.
Better still, Dan showed an interest in me, which I had never experienced from my own father. Dan was always around when I needed advice on school or friends. Once I begin to warm up to Dan, the three of us began spending a lot of time together. We often went out to eat and took short trips. Eventually, I discovered that I finally had the happy family that I had always wanted.
I now realize my parents were right about getting the divorce. Their breakup was the best thing to happen for all of us. My father also found happiness— he remarried and had another child, my half –sister, Michelle.

A young woman was driving through the lonely countryside. It was dark and raining. Suddenly she saw an old woman by the side of the road, holding her hand out as if she wanted a lift. ―I can’t leave her out in this weather,‖ the woman said to herself, so she stopped the car and opened the door. ―Do you want a lift?‖ she asked. The old woman nodded and climbed into the car. After a while, she said to the old woman, ―Have you been waiting for a long time?‖ The old woman shook her head. ―Strange,‖ thought the young woman. She tried again. ―Bad weather for the time of year,‖ she said. The old woman nodded. No matter what she said, the hitchhiker (搭便车的人)gave no answer except for a nod of the head or a shrug.
Then the young woman noticed the hitchhiker’s hands which were large and hairy.
Suddenly she realized that the hitchhiker was actually a man! She stopped the car. ―I can’t see out of the rear screen,‖ she said, ―Would you mind clearing it for me?‖
The hitchhiker nodded and opened the door. As soon as the hitchhiker was out of the car, the terrified young
woman raced off.
When she got to the next village she pulled up. She noticed that the hitchhiker had left his handbag behind. She picked it up and opened it. She gave a gasp; inside the bag was a gun.

Have you ever stood side by side with an elephant and touched its ear or its long nose? A marvelous opportunity is offered here for you to experience working with these giant animals. The daily highlight is the walk from the elephant orphanage down to the river to bathe the elephants. Imaging what an amazing fun it is to watch an entire herd splashing（溅湿）around and rolling in the river just feet in front of you!
This opportunity is available through a programme designed for visitors and volunteers to work in the world-famous government-run elephant orphanage in Pinnawela, Sri Lanka. The orphanage is regarded as one of the largest centers of its kind in the world, with one of the most successful captive breeding（人工饲养）programmes for Asian elephants.
Pinnawela Orphanage is situated in the hills of central Sri Lanka. It was established in 1975 by the Sir Lanka Wildlife Department. The orphanage’s 24 acres（英亩）are a home for the many baby elephants found in the jungle without their mothers. In most of these cases the mothers had either died or been killed. Baby elephants cared for by the orphanage are released into the wild when they reach a certain age.
The volunteers’ working hours are quite short so there is plenty of time to sightsee and explore. The volunteer work consists mainly of the day-to-day aspects of running the orphanage, rather than more specialized research-based work.
The volunteers’ main duties are cleaning the elephant homes in the morning (hard, muddy work!) and bathing some of the smaller elephants. Some elephants are overly large or have not been tamed or trained to a satisfactory level. However there are still enough opportunities to have full hands-on contact safely.
While the mahouts are bathing the larger elephants, you will have a chance to relax by the river, chat with the mahouts and watch the elephants play and interact（互动）with humans and each other. It is an absolutely beautiful sight. Being around these serene animals in such a beautiful setting can have a very calming effect!
If you are interested in such an experience, contact us for more information.
59. How many main duties does the passage list for the volunteers?
A. Two.
B. Three.
C. Four.
D. Five.
60. The passage’s goal is to.
A. describe the elephant orphanage in Pinnawela, Sri Lanka.
B. attract more tourists to come for sightseeing
C. get volunteers for Pinnawela Elephant Orphanage
D. call on people to care for baby elephants
61. Mahouts are probably people who .
A. train elephants
B. bathe elephants
C. care for elephants
D. drive elephants
62. The underlined word hands-on in the fifth paragraph probably means .
A. doing something rather than talking about it
B. doing something by hand
C. letting others do it
D. a very close relationship
D
An allowance(零花钱) is an important tool for teaching children how to make plans for the use of money, save and make their own decisions. Children remember and learn from mistakes when their own dollars are lost or spent foolishly. How large is an allowance is suitable? Experts say there is no right amount. Actually amounts differ from region to region, and from family to family.
To set up a suitable allowance for your child, work up a weekly plan. Allow for entertainment costs such as movies or fast food. Next, include everyday expenses such as lunch money, bus fare, school supplies. ―If you make the child responsible for these bills,‖ says Josephine ，a specialist , ―he or she will learn to plan for necessary costs.‖
Finally, add some extra money to make saving possible, if you keep your childre n’s allowance in line with that of his friends. A child whose buying power falls away below his peer’s can feel left out.
It can be taught but don’t excuse your children when they make a mistake with their allowance. When Brooke was ten, her mother gave her $5 a week, $1.75 of which was for bus fare and lunch. ―If you lose your money, Brooke‖ mother told her, ―you walk home.‖
One week that girl spent all her money in a candy store; then she called home for a ride. ―Mom made me walk home,‖ recalls Brooke, now a financial planner in a big company. ―At first I was angry. But I finally realized that she was trying to teach me an important lesson.‖
63. What does the passage mainly discuss?
A. How to develop a child’s early habits.
B. How to work up an amount of pocket money
C. How to teach a child to save money
D. How to teach a child about money
64. It can be inferred from the passage that if a child is given an allowance, he or she may____.
A. spend all the money very soon
B. fall into the bad habit of wasting money
C. feel responsible and careful about money
D. lose money and can not return home
65. In pagraph3, the words ―his peers‖ refer to which of the following?
A. His parents
B. His teachers
C. His financial experts
D. His friends
66. Why does the writer mention the girl Brooke?
A. To explain that parents should be strict in developing children’s good habit about money.
B. To question the opinion about pocket money.
C. To compare Brooke with other financial experts.
D. To suggest pocket money is useless in developing a child’s sense of responsibility

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that there are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied(多样的) diet. The bear eats fruits, honey(蜂蜜) and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them over overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for your health. Choosing the right food, therefore, has become an area of study in modern life.
67. We can infer from the text that humans and animals ___________.
A. depend on one sense in choosing food
B. are not satisfied with their food
C. choose food in similar ways
D. eat entirely different food
68. Which of the following eats only one type of food?
A. The white butterfly
B. The small bird
C. The bear
D. The fox
69. Certain animals change their choice of food when _________.
A. the season changes
B. the food color changes
C. they move to
D. they are attracted by different smells
70. We can learn from the last paragraph that ___________.
A. food is chosen for a good reason
B. French and British food is good
C. some people have few choices of food
D. some people cares little about healthy diet
