Have you ever thought, “I wish I could take a year off and just travel around the word?” Well, three lucky American teenagers were able to do just that. The teens — two males and one female — got an all-expenses paid, yearlong hike to five continents.
This trip didn’t include any five-star hotels or shopping funs. Eighteen-year-old Jamie Fiel from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn’t expect fancy treatment. They signed up for the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encounters with some of nature’s most dangerous animals and environments.
Jamie, Arsen, and Tyler were among hundreds of high school kids nominated by their science teachers to take this trip. Earthwatch Institute sponsored this adventure. Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects.
The group went all around the world to get a close look at the most pressing environmental issues of our time. Their assignments were as varied as their locations, and included measuring and attending pink flamingos in Kenya’s Great Rift Valley, and tracking giant sea turtles in Costa Rica.
As they worked with the Earthwatch scientists, Jamie, Arsen, and Tyler began to understand that we are at a critical moment in the life of our planet. Time for change is running out. As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person’s actions. They realized that each of them can make a difference.
小題1:These teenagers went on the journey around the world      .
A．to experience the most serous environmental problems on the earth
B．to bring the kindness of America to the other parts of the world
C．to go on sightseeing around the world
D．to call on more teenagers to join Earthwatch Institute
小題2:What’s TRUE about their journey?
A. They had to pay for their journey on their own expense.
B, They often had to move from one hotel to another.
C. They had to take great pains to collect environmental information.
D. They received a warm welcome every time they arrived at a new place.
小題3:It can be inferred that Earthwatch Institute could be          .
A. an international university that takes in students from all over the world
B. a TV station that makes programmes on the beautiful scenery of the earth
C. a travel agency that organizes adventure trips specially for school children
D. an organization that bring s science to life for people concerned about earth’s environment
小題1:A
小題2:C
小題3:D

Larry was on another of his underwater expeditions(探險)but this time, it was different. He decided to take his daughter along with him. She was only ten years old. This would be her first trip with her father on what he had always been famous for.
Larry first began diving when he was his daughter’s age. Similarly, his father had taken him along on one of his expeditions. Since then, he had never looked back. Larry started out by renting diving suits from the small diving shop just along the shore. He had hated them. They were either too big or too small. Then, there was the instructor. He gave him a short lesson before allowing him into the water with his father. He had made an exception. Larry would never have been able to go down without at least five hours of theory and another similar number of hours on practical lessons with a guide. Children his age were not even allowed to dive.
After the first expedition, Larry’s later diving adventures only got better and better. There was never a dull moment. In his black and blue suit and with an oxygen tank fastened on his back, Larry dived from boats into the middle of the ocean. Dangerous areas did not prevent him from continuing his search. Sometimes, he was limited to a cage underwater but that did not bother him. At least, he was still able to take photographs of the underwater creatures.
Larry’s first expedition without his father was in the Cayman Islands. There were numerous diving spots in the area and Larry was determined to visit all of them. Fortunately for him, a man offered to take him around the different Spots for free. Larry didn’t even know what the time was, how many spots he dived into or how many photographs he had taken. The diving spots afforded such a wide array of fish and sea creatures that Larry saw more than thirty varieties of creatures.
Larry looked at his daughter. She looked as excited as he had been when he was her age. He hoped she would be able to continue the family tradition. Already, she looked like she was much braver than had been then. This was the key to a successful underwater expedition.
小題1:In what way was this expedition different for Larry?
A．His daughter had grown up.
B．He had become a famous diver.
C．His father would dive with him.
D．His daughter would dive with him.
小題2:What can be inferred from Paragraph2?
A．Larry had some privileges.
B．Larry liked the rented diving suits.
C．Divers had to buy diving equipment.
D．Ten-year-old children were permitted to dive.
小題3:Why did Larry have to stay in a cage underwater sometimes?
A．To protect himself from danger.
B．To dive into the deep water.
C．To admire the underwater view.
D．To take photo more conveniently.
小題4:What can be learned from the underlined sentence?
A．Larry didn’t wear a watch.
B．Larry was not good at math.
C．Larry had a poor memory.
D．Larry enjoyed the adventure.
小題5:What did Larry expect his daughter to do?
A．Become a successful diver.
B．Make a good diving guide.
C．Take a lot of photo underwater.
D．Have longer hours of training.

Think about the different ways that people use wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills (風(fēng)車) began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.
For many centuries, people used windmills to grind (磨碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote (偏僻的) areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were rarely used.
During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means high costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.
小題1:From the text we know that windmills _______.
A．were invented by Europeans armies
B．have a history of more than 2800 years
C．used to supply power to electric lights in remote areas
D．have rarely been used since electricity was discovered
小題2: What was a new use for wind power in the late 19th century ?
A．Sailing a boat. B．Producing electricity.
C．Grinding wheat into flour.D．Pumping water from underground.
小題3:One of the reasons why wind was rediscovered in the 1970s is that ______ .
A．wind power is cleaner
B．it is one of the oldest power sources
C．it was cheaper to create energy from wind
D．the supply of coal and gas failed to meet ends
小題4:What would the writer probably discuss in the paragraph that follows ?
A．The advantages of wind power.
B．The design of wind power plants.
C．The worldwide movement to save energy.
D．The global trend (趨勢) towards producing power from wind.

As researchers learn more about how children's intelligence develops, they are increasingly surprised by the power of parents.The power of the school has been replaced by the home.To begin with, all the factors which are part of intelligence—the child's understanding of language，learning patterns, curiosity—are established well before the child enters school at the age of six.Study after study has shown that even after school begins, children's achievements have been far more influenced by parents than by teachers.This is particularly true about learning that is language?related.The school rather than the home is given credit for variations in achievement in subjects such as science.
In view of their power, it's sad to see so many parents not making the most of their child's intelligence.Until recently parents had been warned by educators who asked them not to educate their children.Many teachers now realize that children cannot be educated only at school and parents are being asked to contribute both before and after the child enters school.
Parents have been particularly afraid to teach reading at home.Of course，children shouldn't be pushed to read by their parents, but educators have discovered that reading is best taught individually—and the easiest place to do this is at home.Many four?and five?year?olds who have been shown a few letters and taught their sounds will compose single words of their own with them even before they have been taught to read.
小題1:What have researchers found out about the influence of parents and the school on children's intelligence?
A．Parents have greater influence than the school.
B．The school plays a greater role than parents.
C．Parents and the school have the equal power.
D．Neither parents nor the school has any influence.
小題2:Researchers conclude that________.
A．it is with the help of the teachers that children have an understanding of
language
B．curiosity is formed after the children enter school
C．children's learning patterns are developed at the early age
D．only the school can give children the opportunity to make achievements
小題3:According to the text, in which area may school play a more important role?
A．Moral education.B．Language education.
C．Physical education.D．Science education.
小題4:Many parents fail to make the most of their children's intelligence because
________.
A．they usually push the children to read at home
B．they only teach them after they enter school
C．they teach them in a wrong way at home
D．they were told by educators not to teach their children

Worried about how many calories you will get in that piece of pizza, chocolate cake or bag of chips? A new iPhone application (應(yīng)用程序) MealSnap may help. Users just need to take a picture of the meal with the phone, and it will give a calorie read-out almost immediately.
MealSnap was developed by DailyBurn, a health social network that focuses on helping its users lead healthier lifestyles. It has created several other health and diet-related iPhone applications. The application gives users a quick reply. To do that, it matches the taken picture to a databank (數(shù)據(jù)庫) with the calorie information of nearly 500,000 kinds of food. Users then get the range of calories for the meal that is photographed.
We started with something simple—an apple. A couple of minutes later, the application replied that it was an apple and between 64 and 96 calories. More impressive was the reply we received after sending a photo of a mixed salad bowl. MealSnap replied that the bowl contained “yellow rice with corn, boiled eggs and beans” and that the food was between 532 and 789 calories.
Mr. Smith, director of DailyBurn, said that usual calorie counting needed a long time, but that the application made it easier to know the calories in food. That is why it is so popular among those who are trying hard to lose weight.
In addition, MealSnap can act as a food diary. No need to write down what they’ve eaten, the photoes will be stored. The users can keep a visual log (視覺的記錄). Mr. Smith said, “it’s like a food journey, but easier. All you do is to take the picture. The simple act of recording something can cause a psychological (心理的) change that can help people on their health journey. Knowing the calorie range makes me think more about what I’m eating.”
小題1: The purpose of DailyBurn is to________.
A．help people find ways to lose weight
B．make iPhone more popular
C．persuade people to buy iPhone products
D．help people have a healthy life
小題2: What can be learned from the third paragraph?
A．MealSnap is only useful for simple things.
B．The result of MealSnap isn’t always right.
C．MealSnap can also tell what the food is.
D．MealSnap needs a long time to show the calorie range.
小題3: Which of the following statements about MealSnap is TRUE?
A．It has been put into the market.
B．People will have a physical change by using it.
C．It’s popular because it was developed by DailyBurn.
D．People have to link iPhone with the Internet to use it.
