1 . Rainforests are home to a rich variety of medicinal plants, food, birds and animals. Can you believe that a single bush（灌木丛）in the Amazon may have more species of ants than the whole of Britain! About 480 varieties of trees may be found in just one hectare of rainforest.

Rainforests are the lungs of the planet-storing vast quantities of carbon dioxide and producing a significant amount of the world's oxygen. Rainforests have their own perfect system for ensuring their own survival; the tall trees make a canopy（树冠层）of branches and leaves which protect themselves, smaller plants, and the forest animals from heavy rain, intense dry heat from the sun and strong winds.

Amazingly, the trees grow in such a way that their leaves and branches, although close together, never actually touch those of another tree. Scientists think this is the plants' way to prevent the spread of any tree diseases and make life more difficult for leaf-eating insects like caterpillars. To survive in the forest, animals must climb, jump or fly across the gaps. The ground floor of the forest is not all tangled leaves and bushes, like in films, but is actually fairly clear. It is where dead leaves turn into food for the trees and other forest life.

They are not called rainforests for nothing! Rainforests can generate 75%of their own rain. At least 80 inches of rain a year is normal-and in some areas there may be as much as 430 inches of rain annually. This is real rain-your umbrella may protect you in a shower, but it won't keep you dry if there is a full rainstorm. In just two hours, streams can rise ten to twenty feet. The humidity（湿气）of large rainforests contributes to the formation of rainclouds that may travel to other countries in need of rain.

2 . When I was six, Dad brought home a dog one day, who was called “Brownie”. My brothers and I all loved Brownie and did different things with her. One of us would walk her, another would feed her, then there were baths, playing catch and many other games. Brownie, in return, loved each and every one of us. One thing that most touched my heart was that she would go to whoever was sick and just be with them. We always felt better when she was around.
One day, as I was getting her food, she chewed up(咬破)one of Dad’s shoes, which had to be thrown away in the end. I knew Dad would be mad and I had to let her know what she did was wrong. When I looked at her and said, “Bad girl,” she looked down at the ground and then went and hid. I saw a tear in her eyes.
Brownie turned out to be more than just our family pet. She went everywhere with us. People would stop and ask if they could pat her. Of course she’d let anyone pat her. She was just the most lovable dog. There were many times when we’d be out walking and a small child would come over and pull on her hair. she never barked(吠) or tried to get away. Funny thing is that she would smile. This frightened people because they thought she was showing her teeth. Far from the truth, she loved everyone.
Now many years have passed since Brownie died of old age. I still miss days when she was with us.

3 . For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?

Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness. And of course, the teens see it in exactly the same way, except oppositely. Both feel trapped.

In this article, I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrels over unimportant things. Examples include the color of the teen’s hair, the cleanliness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right. It doesn’t matter what the topic is—politics, the laws of physics, or the proper way to break an egg—the point of these arguments is to prove that you are right and the other person is wrong, for both wish to be considered an authority—someone who actually knows something—and therefore to command respect. Unfortunately, as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progress.

1. Why does the author compare the parent-teen war to a border conflict?

A．Both are about where to draw the line.

B．Both can continue for generations.

C．Neither has any clear winner.

D．Neither can be put to an end.

2. What does the underlined part in Paragraph 2 mean?

A．The teens tend to have a full understanding of their parents.

B．The teens agree with their parents on the cause of the conflict.

C．The teens cause their parents of misleading them.

D．The teens blame their parents for starting the conflict.

3. Parents and teens want to be right because they want to ______.

A．give orders to the other

B．know more than the other

C．gain respect from the other

D．get the other to behave properly

4. What will the author most probably discuss in the paragraph that follows?

A．Solutions for the parent-teen problems.

B．Examples of the parent-teen war.

C．Causes for the parent-teen conflicts.

D．Future of the parent-teen relationship.

4 . “They tell me that you’d like to make a statue(塑像) of me-is that correct, Miss Vinnie Ream?”

The deep, gentle voice helped calm the nervous girl. Asking a favor of the President of the United States was no casual matter, especially for a seventeen-year-old girl.

“Yes, sir,” she replied, her dark eyes meeting his. “I wouldn’t have duo ask you, but my teacher, Mr. Mills, says I am ready. I plan to make it in an admirable manner. “

President Lincoln smiled. “Painters, sculptors-they’ve all tried to make the best of this ordinary face, but I’m afraid there’s not much hope. What did you have in mind, Miss Ream? A bust(半身像)?”

Before Vinnie could say yes, the President hurried on, a shade of apology in his voice.

“Of course-I shouldn’t have asked. A full-length pose would be much too big a project for a young woman your size. “

Vinnie’s face turned red. She realized she looked like a child, with her tiny figure. “Small does not mean weak, sir,” she defended herself. “I was born in the country of Wisconsin. I’ve driven teams of horses and carried water. Making a full-length clay(粘土) figure would not exhaust my strength-and that is what I intend to do!”

The President’s eyes, brightened at her show of spirit. “Sorry, madam, I have underestimated you as I didn’t know your background.”

But his smile faded as he rubbed his beard with bony fingers, in thought. “Miss Ream,” he sighed, “I’d like to let you do it, but as you know, we are in the middle of a war. How could I possibly take the time to pose for a sculpture now? I hardly have a minute to myself.”

Vinnie glanced around and noted the size of his office. “I work quickly,” she said. Her voice was soft but confident as she pointed to the corner near the windows. “If I were to bring my clay here and work for three hours every afternoon, I could complete most of the project while you are at your desk.”

The President seemed to consider her idea seriously. He got up and shook Vinnie’s hand warmly, “I’ve heard that you are a talented young woman, and I have found you charming and intelligent as well. I cannot make my decision immediately, but you will hear from me soon.”

The very next day, Vinnie received an invitation from the President.

5 . If you were bringing friends home to visit, you could show them the way. You know the landmarks—a big red house or a bus-stop sign. But what if you were swimming in the middle of the Atlantic Ocean? Could you still find your way home? A loggerhead turtle（海 龟）could.

According to Dr. Ken Lohmann, loggerheads have a magnetic（磁力的）sense based on Earth’s magnetic field. It helps them locate the best spots for finding food and their home beaches.

Scientists already know that several other animals, such as whales and honeybees, can detect（探测到）magnetic fields. The difference between them and loggerheads, however, is the way they learn to use their magnetic sense. Young whales and honeybees can learn from adults. Loggerheads are abandoned as eggs.

As newborn loggerheads have no adults to learn from, what helps them figure out how to use their magnetic sense? Lohmann thinks one of the cues was light on the sea.

Baby loggerheads hatch only at night. However, a small amount of light reflects off the ocean. The light makes that region brighter. Heading toward the light helps them get quickly out to sea, where they can find food. Lohmann tested whether newborn loggerheads use this light source to set their magnetic “compasses”（罗盘）. He and his team put some newborns in a water tank and recorded which way they swam. Around the tank, the scientists created a magnetic field that matched the Earth’s. They set a weak light to the east of the magnetic field. Then they let the newborns go.

At first, the newborns swam toward the light. After the scientists turned off the light, the turtles that had seen the light in the east always swam toward east. When the researchers reversed（颠倒）the magnetic field, these turtles turned around and swam toward the new “east”.

This and the follow-up experiments all showed that loggerheads use light from the outside world to set their magnetic “compasses” and then remember the “correct” direction. If a turtle hatches on a brightly-lit beach, that would damage its magnetic sense forever and make survival hard for the turtle.

Lohmann’s work has led others to protect the habitat of this endangered species. Yet many questions about these creatures remain unanswered, and researchers have a lot to study.

6 . With a satisfied smile, Keisha finished the last sentence of her English essay about one of her heroes, Rosa Parks, an important figure in the Civil Rights Movement.

“Keisha,” her mother shouted from downstairs. “It’s almost 4:15.”

“Don’t worry. I won’t be late. ” Keisha pulled down a storybook from her bookshelf， as she always read to the nursing home’s residents. And on an impulse（一时心血来潮）, she added her English notebook as well.

As Keisha came running in the door, the manager told her, “We have a new resident this week, Mrs. Ruby Watson. She’s still adjusting to her new surroundings. You’ll find her in Room 28. And by the way, Keisha, good luck.”

Keisha walked down the hallway at a quick pace. As she entered Room 28, she met two sharp brown eyes staring at her doubtfully.

“I’m Keisha Jackson, a volunteer,” Keisha explained. “I come here to help pass the time with residents, or read to them, or, . . .” Keisha started stammering（结巴）as Mrs.

Watson continued to stare at her.

“I didn’t request anyone to keep me company,” Mrs. Watson interrupted. “I’m alone most of the time, and that’s how I prefer it.”

“I brought along some funny stories,” Keisha said hesitantly.

“I’m not in the mood for funny stories,” Mrs. Watson replied angrily. “What else do you have?”

Nervously, Keisha opened her notebook to her essay. She read the title aloud, “Rosa

Parks: A Woman of Courage and Conviction（信念）.” She glanced at Mrs. Watson to see how she might react, but to her surprise, Mrs. Watson’s face relaxed and her eyes shone.

“Read to me about Rosa,” Mrs. Watson said.

Keisha read how Rosa Parks’ refusal to give up her seat to a white passenger on a bus in 1955 inspired the protest that became a turning point in the struggle for civil rights.

“I walked with Rosa Parks and Dr. Martin Luther King,” Mrs. Watson said with pride. “That was the greatest moment of my life because…” She paused.

“Because… you were a woman of courage and conviction too.”

Sitting up straighter, Mrs. Watson said, “Yes, I was and I still am. Thank you for reminding me, Keisha. Next Thursday, I will tell you my story.”

9 . Today's world is not an easy adjustment for young adults. Key skill set for success is persistence (毅力), a characteristic that researchers say is heavily influenced by fathers. Researchers from Brigham Young University discovered that fathers are in a unique position to help their adolescent children learn persistence.

BYU professors Laura Padilla-Walker and Randal Day arrived at these findings after following 325 American families over several years. And over time，the persistence gained through fathers led to higher achievement in school.

"There are relatively few studies that stress the unique role of fathers，"Padilla-Walker said. "This research also helps to prove that characteristics such as persistence-which can be taught-are key to a child's life success.”

Researchers determined that dads need to practice an "authoritative" parenting style. Authoritative parenting is not authoritarian:rigid，demanding or controlling. Rather，an authoritative parenting style includes some of the following characteristics:children feel warmth and love from their father；responsibility and the reasons behind rules are stressed children are given an appropriate level of autonomy(自主权).

In the study，about 52 percent of the dads exhibited above-average levels of authoritative parenting. A key finding is that over time，children raised by an authoritative father were significantly more likely to develop persistence，which leads to better outcomes in school.

This particular study examined 11 to 14-year-olds living in two-parent homes. Yet the researchers suggest that single parents still may play a role in teaching the benefits of persistence，which is an avenue of future research.

1. What is special about the BYU professors' study?

A．It centered on fathers' role in parenting.

B．It was based on a number of large families.

C．It analyzed different kinds of parenting styles.

D．It aimed to improve kids' achievement in school.

2. What would an authoritative father do when raising his children?

A．Ignore their demands.	B．Make decisions for them.
C．Control their behaviors.	D．Explain the rules to them.

3. Which group can be a focus of future studies according to the researchers?

A．Single parents.

B．Children aged from 11 to 14.

C．Authoritarian fathers.

D．Mothers in two-parent homes.

4. Which of the following is the best title for the text?

A．Three Characteristics of Authoritative Fathers.

B．Key Skills for Young Adults to Succeed in Future.

C．Children Tend to Learn Determination from Father.

D．Family Relationship Influences School Performance.

10 . Milwaukee, Wisconsin, is road testing a new way to keep winter roads ice-free – by spreading on them cheese brine, the salty liquid used to make soft cheese, like mozzarella.

Wisconsin, also called "America's Dairyland," is famous for its cheese. The state produced 2.8 billion pounds of cheese last year! As a result, there was a lot of leftover cheese brine. Disposing of(处置)the brine can be expensive. So what should cheese makers do with the waste?

Normally, towns use rock salt to de-ice streets. The salt lowers waters' freezing point, causing ice to melt(融化). But using cheese brine could help both cheese producers and cities save money, while keeping roads safe. Cheese brine has salt in it, which, like the rock salt, helps lower water's freezing point.

In addition to saving money, cheese brine could also be a more environment-friendly option. Many people suspect that all the rock salt used every winter is harming the environment.

Rock salt is made of sodium chloride, the sane con-pound (化合物)in ordinary table salt. Sounds harmless, right? But while you probably add only a small amount of salt to your food, road crews spread about 20 million tons of salt on U.S. Roads every year!

The chemical washes off roads and goes into the ground. There it can pollute drinking water, harm plants. and eat away soil. By spreading cheese brine on streets before adding a layer of rock salt, Milwaukee may be able to cut its rock salt use by 30 percent.

Cheese brine has a downside too – a shell similar to that of bad milk. "I don't really mind it," Emil Norby told Modern Farmer magazine. He works for one of Wisconsin's county highway commissions and came up with the idea of using cheese brine. "Our roads smell like Wisconsin!" he said.

1. Why can cheese brine help keep winter roads ice-free?

A．It is soft.

B．It contains salt.

C．It is warm.

D．It has milk in it.

2. What is a benefit of using cheese urine on roads?

A．Improving air quality.	B．Increasing sales of rock salt.
C．Reducing water pollution.	D．Saving the cheese industry.

3. Milwaukee's new way to de-ice streets may be an example of_______________.

A．barking up the wrong tree	B．putting the cart before the horse
C．robbing Peter to pay Paul	D．killing two birds with one stone
