A.Having not accompanied
B.Not having been accompanied
C.Having not been accompanying
D.Not having accompanied

Dear Tom,
Last summer I take a part-time job in the International Camp for children. I have told one more worker will be needed in this year and I think you are fit for it. How about join us? The camp is at the foot of a small hill closed to a river. It's such beautiful a place! We can hear birds singing happy all round. Everybody sleeps in tents, that is very exciting. We usually work only five hours a day, so we will have a lot of spare time to visit the area or have fun. I am sure it will be a unforgettable experience. If you have an interest in it, write to me soon

【題目】根據(jù)短文理解,選擇正確答案。
Renaissance is a French word. It means “rebirth”. It's a strange name for a period of history. What was exactly “ reborn” during the Renaissance?
To answer this question, we need to look back at the time of the Roman Empire. At this time Roman artists, scientists and writers influenced by Greek ideas were the world's most advanced. They had become skilled observers of the natural world around them, and had become experts in studying animals, plants, the human body or the stars and planets. They wrote down their ideas about what they saw, and based their theories about the world on their observations.
During the fourth and fifth centuries the Roman Empire slowly broke down. Many of the Romans' art and sculptures were destroyed and some manuscripts(原稿)were lost as well. But most importantly, some of the ancient attitudes were lost. A questioning approach to the world was replaced by an unquestioning one.
Why did this happen? One reason was to do with the influence of the Christian Church. Through the thousand years following the fall of the Roman Empire, the Church controlled many aspects of life including education and learning. The Church ran all the universities and thought that the aim of a university should be to teach old ideas more clearly, not to introduce new ones. The scholars in the universities were expected to study God and heaven from the Bible and ancient books, rather than the world around them.
Take medicine for example. The main textbook for doctors had been written by a Greek doctor called Galen more than a thousand years earlier. But when Roger Bacon, a thirteenth-century priest(牧師), said that a new approach to medicine was needed --- doctors should do their own original research instead of reading writers from the past such as Galen-the Church put him in prison.
By the time of the fourteenth century, however, some parts of the Christian Church were becoming less strict about their ideas and there was a new state of mind among artists, doctors and scientist. People wanted to find out more about the world by studying it. This attitude of investigation had been common in classical scholars, and it was ‘reborn' during the Renaissance.
(1)We know from the text that scientists at the time of the Roman Empire believed in_______.
A.their companions' observations
B.what they saw with their own eyes
C.what they learned from the Greeks
D.the most advanced theories at that time
(2)We can infer that students in the Church controlled universities might_________.
A.have good memories
B.change their beliefs
C.be lacking in creativity
D.be interested in astronomy
(3)Roger Bacon was put in prison because he_________.
A.gave up being a priest
B.showed no respect for Galen
C.did some research secretly
D.challenged the Church
(4)The text probably comes from a book about_________.
A.medicine
B.education
C.religion
D.history

【題目】I still remember that summer before college.There were plans and ideas about what my college experience was going to be like, but none of them worked out as planned.1.

●Use the mental health services available to you.

That first night at college was memorable. There was scare and homesickness. Missing things from home wasn't the only reason why I felt down. The academic pressure to succeed and the social pressure to fit in are too much for some people, which don't just happen in the freshman year.2. Close friends always guided me, which was important because talking helps—even if it's just with a friend. Don't be afraid to take that extra help.

3.

I had been ready to major in politics, philosophy and economics, in preparation for a law degree.Things changed.

You meet new people and discover new interests.4. So, don't worry if you haven’t figured out exactly what you're going to major in. It will likely change anyway.

●You're there to get a degree, but a little fun won't hurt.

As time goes by, I'm not going to remember the grades I got on papers or the late nights spent studying. Instead, lifelong memories will include playing video games with my roommate at 3:00 am, or late-night runs with my friends after a night out. Apart from doing well inside the classroom, there are also internships(實習(xí)期) and other pressures. Employers might weigh internships more heavily than your GPA.5.

A. It's OK to change your mind about your major.

B. You don't want to get tired of your college life early.

C. Everyone says that college is the best four years of your life.

D. Here are the things I wish I had known before my freshman year.

E. It’s normal to be a little unsure of your plans once you start taking classes.

F. Getting internships and having fun with friends are also of great importance.

G. For me, there were upsets long after the days that required a map to go anywhere.

【題目】閱讀理解
As computers become more popular in China,Chinese people are increasingly depending on computer keyboards to input Chinese characters.But if they use the computer too much,they may end up forgetting the exact strokes of each Chinese character when writing on paper.Experts suggest people,especially students,write by hand more.
Do you write by hand more or type more?In Beijing,students start using a computer as early as primary school. And computer dependence is more widely spread among university students.Almost all their assignment and essays are typed on a computer.
All the students interviewed say they usually use a computer.
It's faster and easier to correct if using a computer.And that's why computers are being applied more and more often to modern education.But when people are taking stock in computers increasingly,problems appear.
“When I'm writing with a pen,I find I often can't remember how to write a character,though I feel I'm familiar with it.”
“I'm not in the mood to write when faced with a pen and paper.”
Many students don't feel this is something to worry about.Now that it's more convenient and efficient to write on a computer,why bother to handwrite?
Many educators think differently. Shi Liwei, headmaster of a famous primary school in the capital said,“Chinese characters enjoy both practical and aesthetic value.But those characters typed with computer keyboards only maintain their practical value.All the artistic beauty of the characters is lost.And handwriting contains the writer's emotion. Through one's handwriting,people can get to know one's thinking and personality.Beautiful writing will give people a better first impression of them.”
To encourage students to handwrite more,many primary schools in Beijing have made writing classes compulsory(必修的)and in universities,some professors are asking students to turn in their homework and essays written by hand.
(1)The underlined expression “taking stock in” in paragraph 4 probably means.

【題目】Christmas was near a season that we took seriously in our house. But a week or so before the 25th, my father would give each of his children $ 20. This was the 1970s, and $ 20 was quite a bit of money.

But I saw it differently. My father trusted me to have the smart to spend money wisely. Even better, he gave me the means to get it. On a very basic level, my father was giving me a shopping spree (狂歡) every year.. But he was also giving me charge over my own fun, trusting my ability to manage money and making me feel like a grown-up. He didn’t buy me Sherlock Holmes, but he gave me the means to walk into the bookstore and choose it for myself, so it felt like a gift from him.

My mother had a gift for giving me what I needed, usually right at the moment I needed it most. This was when I was 25, I failed at being an adult on my very first try. I had quitted my previous job but had no new one. But when my mother paid me a visit, I put on a good show, telling her I had started my own company.

My mother knew that I was trying hard and failing at that time. It wasn’t until after she left that I noticed at the foot of my bed an envelope thick with cash. She knew how desperately I needed it. She knew that had she just shown up with groceries, or offered to pay my rent, she would have made me feel much worse. The cold, hard cash meant she was helping me. And, funnily enough, the distance with which she gave the gift felt like she was giving me space to fix my life and preserve my dignity. My mother and father both did the same thing. One was giving me the means to take my own decisions, and the other was giving me a second chance when those decisions had cost me dearly.

1What can we learn about the author from the first two paragraphs?

A. His family once celebrated Christmas happily.

B. His father gave the author chances to make decisions.

C. His best memories about Christmas were in the 1970s.

【題目】根據(jù)短文理解,選擇正確答案。
Mountaineers have noted that as they climb, for example, up to the 12,633foot Humphreys Peak in Arizona, plant life changes greatly. In the Sonoran Desert, one climbs into a pine forest at 7,000 feet and a treeless tundra(凍土帶) on the top of the mountain. It may seem that plants at a given altitude are associated in what can be called “communities” -groupings of species. The idea is that over time, plants that require particular climate and soil conditions come to live in the same places, and are frequently to be found together. Scientists study the history of plant life and build up a picture of how groups of plants have responded to climate changes and how ecosystems develop. But are these associations, which are real in the present, permanent?
A great natural experiment took place on this planet between 25,000 and 10,000 years ago, when small changes in the earth's orbit caused great sheets of ice to spread from poles. These glaciers(冰川) covered much of North America and Europe to depths of up to two miles, and then, as the climate warmed, they retreated. During this retreat, they left behind newly uncovered land for living things to occupy, and as those living things moved in they laid down a record we can read now. As the ice retreated and plants started to grow near a lake, they release pollen(花粉). Some would fall into the lake, sink to the bottom and mix with the sand. By drilling into the lake bottom it is possible to read the record of the plant life around the lake. The fossil record seems clear; there is little or no evidence that entire groups of plants moved north together. Things that lived together in the past don't live together now, and things that live together now didn't live together in the past. Each individual living things moved at its own pace. The fossil record seems to be telling us that we should be thinking about preserving species by giving them room to move about-to respond to environmental changes.
(1)According to the passage, the movement of individual species of plants ________.
A.occurs in groups
B.often depends upon the formation of lakes
C.does not occur in groups
D.depends upon climate and soil conditions
(2)All of the following are true EXCEPT ________.
A.The ice age occurred when there were small changes in the orbit of the earth
B.fossil records seem to indicate that plants will be preserved if they have enough room to move
C.fossil records clearly show that entire groups of plants are unlikely to have moved together
D.in the ice age glaciers covered the world to depths of up to two miles
(3)The underlined word “which” refers to ________.
A.the responses of plants to climate changes
B.the current theories of ecosystems
C.the development of ecosystems
D.plant life changes
(4)The second paragraph is intended to ________.
A.support the main idea of the first paragraph
B.answer the question raised in first paragraph
C.make suggestions about responding to environmental changes
D.stress the importance of preserving species
