A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate.Without the forest cover,these areas would reflect more heat into the atmosphere,warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns,potentially causing certain natural disasters all over the world.
In the past hundred years,humans have begun destroying rainforests in search of three major resources(资源): land for crops,wood for paper and other products,land for raising farm animals.This action affects the environment as a whole.For example,a lot of carbon dioxide(二氧化碳) in the air comes from burning the rainforests.People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.
There are two main reasons for this.Firstly,when people cut down trees,generally they can only use the land for a year or two.Secondly,cutting large sections of rainforests may provide a good supply of wood right now,but in the long run it actually reduces the world’s wood supply.
Rainforests are often called the world’s drug store.More than 25% of the medicines we use today come from plants in rainforests.However,fewer than l%of rainforest plants have been examined for their medical value.It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.
Rainforests can help to adjust the climate because they                

A.reflect more heat into the atmosphere
B.bring about high rainfall throughout the world
C.rarely cause the temperature to drop lower than l6℃
D.reduce the effect of heat from the sun on the earth

What does the word “this” underlined in the third paragraph refer to? 

A.We will lose much more than we can gain.
B.Humans have begun destroying rainforests.
C.People have a strong desire for resources.
D.Much carbon dioxide comes from burning rainforests.

It can be inferred from the text that      

A.we can get enough resources without rainforests
B.there is great medicine potential in rainforests
C.we will grow fewer kinds of crops in the gained land
D.the level of annual rainfall affects wind patterns

What might be the best title for the text? 

A.How to Save Rainforests B.How to Protect Nature
C.Rainforests and the Environment D.Rainforests and Medical Development

Sure, it’s good to get along with your teacher because it makes the time you spend in the classroom more pleasant.
And yes, it’s good to get along with your teacher because, in general, it’s smart to learn how to understand the different types of people you’ll meet throughout your life.
“But really, there’s one super-important reason why you should get along with your teacher. When you do, learning bursts right open,” says Evelyn Vuko, a longtime teacher who writes an education column(专栏) called “Teacher Says” for the Washington Post newspaper.
In fact, kids who get along with their teachers not only learn more, but they’re more comfortable asking questions and getting extra help. This makes it easier to understand new material and do your best on tests. When you have this kind of relationship with a teacher, he or she can be someone to turn to with problems, such as problems with learning or school life, such as bullying.
As a kid in a primary or middle school, you’re at a wonderful stage in your life. You’re like a sponge (海绵), able to absorb lots of new and exciting information. On top of that, you’re able to think about all this information in new ways. Your teacher knows that it, in most cases, is very excited to be the person who’s giving you all that material and helping you make it. Remember, teachers are people, too, and they feel great if you’re open to what they’re teaching you. That’s why they wanted to be teachers in the first place—to teach!
Some kids may be able to learn in any situation, whether they like the teacher or not. But most kids are sensitive to the way they get along with the teacher, and if things aren’t going well, they won’t learn as well and won’t enjoy being in class.
In the passage, the author mainly talks about _______.

A.how to get along well with others
B.the importance of a good relation with teachers
C.how to make the time in the classroom more pleasant
D.how much the students are expected of to get along with teachers

A.The more questions you ask, the higher marks you will get.
B.Many kids can do well without a good relationship with teachers.
C.If you get on well with your teachers, you must have a good result in exams.
D.if you have a good relationship with your teacher, you can turn to him when in trouble.

Which of the comments is FALSE on teachers and their work according to the passage?

A.Teachers sometimes have the same feelings as students do.

A 17-year-old boy, caught sending text messages in class, was recently sent to the vice principal's office at Millwood High School in Halifax, Nova Scotia.
The vice principal, Steve Gallagher, told the boy he needed to focus on the teacher, not his cellphone. The boy listened politely and nodded, and that's when Mr. Gallagher noticed the student's fingers moving on his lap. He was texting while being scolded for texting!
"It was a subconscious(下意识的) act," said Mr. Gallagher, who took the phone away. "Young people today are connected socially from the moment they open their eyes in the morning until they close their eyes at night. It's addictive(上瘾的). They can’t simply stop doing that."
Because so many people in their teens and early 20s are in this constant whir of socializing – accessible(易接近的) to each other every minute of the day via cellphone, instant messaging and social-networking Web sites -- there are a host of new questions that need to be addressed in schools, in the workplace and at home. Chief among them: How much work can "hyper-socializing" students or employees really accomplish if they are holding multiple conversations with friends via text-messaging, or are obsessively checking Facebook? Almost a quarter of today's teens check Facebook more than 10 times a day, according to a 2009 survey by Common Sense Media, a non-profit group that monitors media's impact on families.
Will these young people get rid of this habit once they enter the work force, or will employers come to see texting and "social-network checking" as accepted parts of the workday?
"In past generations, students got in trouble for passing notes in class. Now students are adept at texting with their phones still in their pockets," said 40-year-old Mr. Gallagher, "and they're able to communicate with someone one floor down and three rows over. Students are just fundamentally different today. They will take suspensions(休学) rather than give up their phones."
When the boy was scolded for texting, _________________.

A.he was polite and regretful
B.he was trying sending another message
C.his fingers shouldn’t be put on his lap
D.he listened carefully and nodded

From what the boy did we know___________.

B.The boy will stop using the cellphone
C.The boy will leave school
D.The boy wasn’t willing to accept being scolded

B.They will get rid of the habit once they go to work.
C.They are greatly different from the past generations.
D.Most of them check Facebook more than 10 times a day.

Years ago, I lived in a building in a large city. The next building was only a few feet away from mine. There was a woman living there, and I had never met her, yet I could see she sat by her window each afternoon, sewing or reading.
After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself. “I wonder why that woman doesn’t wash her window. It really looks terrible.”
One bright morning I decided to clean my flat, including washing the window on the inside.
Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was clearly visible (看见). Her window was clean!
Then it dawned on me. I had been criticizing (批评) her dirty window, but all the time I was watching hers through my own dirty window.
That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own shortcomings?
Since then, whenever I wanted to judge (评判) someone, I asked myself first, “Am I looking at him through my own dirty window?” I try to clean the window of my own world so that I may see the world about me more clearly.

Here is some must-know information from a handbook on how people behave in doing business in some countries.
In Brazil
Brazilians are warm and friendly. They often stand close when talking and it is common for them to touch the person on the shoulder. People often greet each other (particularly women) with light cheek kisses. Schedules tend to be flexible, with business meetings sometimes starting later than planned. But to be safe, be on time. Meals can stretch for hours—there’s no such thing as rushing a meal in Brazil. Lunches also can start in the mid to late afternoon. Brazilians are social, preferring face-to-face communication over mails or phone calls.
In Singapore
Singaporeans shake hands when they meet and often also greet each other with a small, polite bow. Business cards should be offered and received with two hands. Arriving late is considered disrespectful. So be on time. Efficiency(效率) is the goal, so meetings and dealings often are fast-paced. Singaporeans are direct in their discussions, even when the subject is about money. Rank is important and authority(权威)is respected. This determines both people interact in meetings. For example, people avoid disagreeing outright with someone with a higher rank.
In the United Arab Emigrates
In the UAE, status is important, so the most senior or oldest should be greeted first with their titles. The handshake seems to be longer than elsewhere. So, do not pull away the handshake. Women should cover themselves when it comes to dress. Men also tend to be covered from neck to elbows(肘部) and down to the knees. People do not avoid entertaining(娱乐 in their homes, but they also hold business meals at restaurants. Touching or passing food or eating with your left hand is to be avoided. When meetings are one-to-one, if your host offers you coffee, you should refuse. It might seem odd, but it is a cultural tradition. Coffee should only be accepted if it is always set out or presented.
In Switzerland
The Swiss tend to be formal and address each other by last name. They also are respectful of private lives. You should be careful not to ask about personal topics. Punctuality (守时) is vital, something that comes from a deep respect for others’ time. Arrive at any meeting or event a few minutes early to be safe. They also have clear structure in their companies. Higher-ups make the final decisions, even if others might disagree. Neat, clean dress is expected. The Swiss follow formal table manners. They also keep their hands visible at the table and their elbows off the table. It is polite to finish the food on your plate.
The passage is mainly about ________.

A.communication types
B.the workplace atmosphere

As a recipe for losing weight, taking a slice of chocolate cake at breakfast would seem an unlikely fantasy.
A team from Tel Aviv University found that eating pudding as part of a balanced 600-calorie breakfast that also included proteins and carbohydrates (碳水化合物), could help dieter to lose more weight---and keep it off in the long run.
Attempting to avoid sweets entirely can create a psychological addiction to these same foods in the long term. So adding desserts to breakfast can control craving(渴望) throughout the rest of the day.
Over the course of a 32-week-long study, participants, who added desserts to their breakfast lost about 40 pounds more than a group that avoided such foods. What’s more, they kept off the pounds longer.
A meal in the morning provides energy for the day’s tasks, aids in brain functioning, and kick-starts the body’s metabolism (新陈代谢), making it decisive to weight loss and maintenance. And breakfast is the meal that most successfully regulates ghrelin, the hormone that increases longer. While the level of ghrelin rises before every meals, it is controlled most effectively at breakfast time.
The researchers hoped to determine whether meal time and composition had an impact on weight loss in the short and long term, or whether it was a simple matter of the caloric count.
According to the passage, the underlined word “it” in paragraph 2 probably refers to __________.

A.the calorie B.the breakfast
C.the craving for pudding D.the lost weight

B.some decisive ways of losing weight
C.the great importance of breakfast to us
D.the nutrition we should take in during the breakfast

What will the passage develope next?
