A
Iceland lies in the North Atlantic Ocean. It is the second largest island in Europe. The country has a total area of 103,000 square kilometers and a coastline of about 6,600 km. The island is 300 km wide from north to south, and 500 km across from west to east.
From 1262 to 1944 Iceland was ruled first by Norway and then by Denmark. Centuries of foreign rule, and such things as volcanoes(火山) and the weather, made life very difficult at times for the Icelanders: there was lots of hard work and little change. The situation began to improve during the nineteenth century. Then in 1944 Iceland became an independent republic; since that time it has become a quite rich country where the people enjoy having cars, modern houses and lots of electrical equipment. If you look at the kind of products that Iceland exports today—fish, meat and wool for example—it’s easy to see that both the sea and the land are important to Icelanders. This has been true in fact since the time of the first Icelanders—Vikings from Norway who arrived in AD874.
Some things in the lives of the Icelanders have changed very little—the Icelandic language, for example, 700 years ago the stories called Sagas were first written down, these can still be read in the old language without much difficulty by Icelandic speakers today.
45. In Iceland, the distance from north to south is _________that from west to east.
A much longer than
B shorter than
C. the same as
D. a little longer than
46. What has hardly changed in Iceland?
A. Exporting products.
B. The Icelandic language.
C. House equipment.
D. The lives of the Icelanders.
47. Which of the following sentences is NOT true?
A. Iceland has been an independent republic since Vikings began to live there.
B. Iceland is a country of many small islands.
C. Iceland is not the largest island in the world,
D. Iceland is quite a modern country now.
B
In 1901, the people of Colorado Springs in the USA decided to collect everyday items and to seal (密封) them in a steel box. The box was marked "To be opened after midnight, December 31st, AD 2000", and was stored in the Colorado College library.
One hundred years later, on the appointed (约定的) day, 300 people gathered to watch the opening of
the box. Many in the crowd were the descendants (后代) of people who put things inside the box.
When the box was opened after midnight, the items were still very good. There were newspapers, photos, diaries, name cards, family trees, books and letters, including one written by Theodore Roosevelt, who became the president of the USA later that year. One of Roosevelt's friends lived in Colorado Springs at that time.
Many of the letters were addressed to their descendants. They describe (描述) the hopes that the people of 1901 had for the people of the next century. At that time, Colorado Springs had just a few thousand people. Now nearly half a million people live there.
Colorado College Library has scanned (扫描) the materials and put them on a website. Cecil Muller, whose grandfather put a collection of postcards in the box, said that the time capsule was a great treasure. "This is a wonderful educational resource. We can learn so much about our history," he said. "I never knew my grandfather, but now I feel very close to him."
In April 2001, a group of people filled the time capsule with items from modern Colorado Springs and resealed it for another hundred years.
48. A "time capsule" is _______________.
A. a collection of clocks and watches
B. a machine for traveling through time
C. a collection of items for people to look at in the future
D. a collection of unwanted items
49. Many of the letters in the time capsule talked about________________.
A. the history of the town
B. the people who lived in the town
C. the politics of the USA
D. people's hopes for the future
50. Cecil Muller says that the time capsule _______________.
A. brings back his memories of his grandfather
B. is worth a lot of money
C. helps him to get to know his grandfather
D. helps him to remember his younger days
C
Technology is everywhere. We see it any place we go to and, in fact, almost all of us carry some piece of technology with us every time we leave the house. What I always forget is just how useful and powerful technology can be when we want to help others.
Every room in my house has some electronic devices (设备). Whenever I am at home, I am almost always using at least one electronic device. If you walked into my living room on any given day, you would find that, first, I have the television on. At the same time, I usually have my laptop resting on my knee, or I will be using my mobile phone. Even when I’m not at home I am always using my phone, and at work or in cafes, I sit down and connect to the local wireless network.
I must say that I waste a lot of time on the computer and the time I spend on it could be much better spent if I were to take up a little online volunteering.
The technology we carry about everywhere can have a great power to do good for the world and to help others and recently I discovered just how much online volunteering there is to do in the world. From using your language skills to do translations, to developing and managing projects and helping with IT work, there is so much that so many people can do to help people in their own countries and across the world. The United Nations, in fact, has a huge page with “V olunteers Recruited” on its website.
This work can support the poor and help charities who cannot pay for staff. Many organizations only need you to work an hour a week—some even less. And online volunteers’ support can really help make a difference to those in need.
51. From Paragraph 2, we can know that the writer ___________.
A. uses technology a lot
B. works in a cafe
C. is a computer engineer
D. likes modern music
52. In the writer’s opinion, people should spend more time _________ with technology.
A. working on computer programs
B. keeping the Internet safe
C. inventing electronic products
D. helping people in need
53. What can be the best title for the passage？
A. Website Design
B. Internet Organizations
C. Online V olunteering
D. Online Translation
D
Here is a story: A man sees a butterfly. The butterfly tries to get out of its chrysalis(蛹). Feeling sorry for it, the man decides to help. He cuts the chrysalis and the butterfly comes out easily. Surprisingly enough, the butterfly is unable to fly. If the butterfly doesn’t struggle (挣扎) to leave the chrysalis, it can’t fly! The struggle develops the energy in the butterfly which makes it fly. Similarly, the challenges (挑战) of life bring out the best in young people and make them fly.
When people are young, meeting and overcoming (克服) challenges will make them strong and ready to face life. When we look at successful people, we see that the most successful people have had to struggle. One famous businessman now owns many big supermarkets. He used to carry clothes on his back and sell them from door to door when he was young. Another successful man is Dennis. His father died when he was only twenty. His father’s death made him grow up fast. He had to bring up a family of nine people. He took up the challenges and overcame them. Today his brothers and sisters are leading successful lives.
Sometimes challenges do not appear to us because we keep away from them. So some parents and teachers actively encourage young people to face challenges. They might organize some activities for young people which provide them with challenges, like rock-climbing, camping, volunteer work and so on. However, just passing exams will not prepare a person for life. We must meet and overcome challenges. The young people of today will become the leaders of tomorrow. For countries to continue to become successful, it is important that the young people learn to meet challenges and overcome them.
54. From the story we know that the butterfly can’t fly because ________.
A. it gets out by itself
B. the man feels sorry for it
C. it tries to challenge itself
D. the man helps it come out
55. Dennis’s example shows that successful people should ________.
A. overcome the difficulties
B. take up business early
C. become the leaders of tomorrow
D. sell clothes from door to door
56. What is the writer trying to do in this passage?
A. Describe where a butterfly comes from.
B. Encourage young people to face challenges.
C. Suggest how to become a successful businessman.
D. Explain what will happen if a person fails the exam.
57. What is the best title for this passage?
A. Successful People Have a Sense of Achievement
B. Young People Must Develop Their Energy Actively
C. Countries Should Continue to Become Successful
D. Challenges of Life Bring Out the Best in Young People

七、阅读填空先通读下面的短文，然后根据短文内容，在文章后表格内填入一个最恰当的单词。每
个空格只能填一个单词。（本大题共5小题，每小题1分，共5分）If you drop a piece of fruit on your computer keyboard, will you think about eating it again? What if you drop it in the toilet? Bacteria (细菌) can live here and there, even in some unexpected places.
If you eat at your computer or sit down to surf the Internet without first washing your hands, your computer keyboard could be bad for your health. According to the US National Research Centre, the average computer carries 400 times more bacteria than a toilet bowl.
Could one of the dirtiest things in your home be right in your hand? Yes, the TV remote control. It gets dropped on the floor, put on the sofa and everyone in the house holds it. Scientists found that around half of the tested remote controls carry the cold virus (病毒).
Don’t forget your toothbrush. Do you put it in the bathroom? Studies show that flushing (抽水冲洗) the toilet releases bacteria in the air. Bacteria can remain in the air for at least two hours. They may pollute your toothbrush. You can find ways to solve this problem. Try to keep your toothbrush far from the toilet.
Make sure that it is in an upright position after each use. It’s also important to change your toothbrush every three months.
The kitchen is one of the places with the most bacteria—more than the bathroom. Dishcloths and kitchen sponges (海绵) are great places for bacteria since they are always wet after being used. Try to make them dry.
Bacteria are everywhere, but don’t be too afraid to touch those things. Most of bacteria are harmless. Just remember to wash your hands often. It is the most useful way to protect yourself from bacteria and
