“I will never marry, ” the future Elizabeth I declared at the age of eight, and, to the terror of her people, the Great Queen kept her word.
For four centuries, historians have guessed why Elizabeth never married. In her own day, her decision to remain single was considered absurd and dangerous. A queen needed a husband to make political decisions for her and to organize and lead her military campaigns. More important, she needed male heirs (继承人) to avoid a civil war after her death.
There was no shortage of suitors for the Queen, both English courtiers (朝臣) and foreign princes, and it was confidently expected for the best part of 30 years that Elizabeth would eventually marry one of them. Indeed, although she insisted that she preferred the single state, she kept these suitors in a state of permanent expectation. This was a deliberate policy on the Queen's part, since by keeping foreign princes in hope, sometimes for a decade, she kept them friendly when they might otherwise have made war on her kingdom.
There were, indeed, good political reasons for her avoiding marriage. The disastrous union of her sister Mary I to Philip II of Spain had had an unwelcome foreign influence upon English politics. The English were generally prejudiced against the Queen taking a foreign husband, particularly a Catholic one. Yet if she married an English, jealousy might lead to the separation of the court.
There were other deeper reasons for Elizabeth's unwillingness to marry, chief of which, I believe, was her fear of losing her autonomy as Queen. In the 16th century, a queen was regarded as holding supreme dominion(统治权)over the state, while a husband was thought to hold supreme dominion over his wife. Elizabeth knew that marriage and motherhood would bring some harm to her power.
She once pointed out that marriage seemed too uncertain a state for her. She had seen several unions in her immediate family break down, including that of her own parents. Elizabeth's father, Henry VIII, had had her mother, Anne Boleyn, killed; her stepmother Catherine Howard later suffered the same fate. When Elizabeth was 14 she was all but attracted by Admiral Thomas Seymour, who also went to the prison within a year. Witnessing these terrible events at an early age, it has been argued, may have put Elizabeth off marriage.
Elizabeth had to decide her priorities. Marriage or being single? Elizabeth was far too intelligent. The choice she made was courageous and revolutionary, and, in the long run, the right one for England.
1.To the suitors including English courtiers and foreign princes, Elizabeth ________.
A. held back the truth
B. gave a definite answer “no”
C. kept them expecting on purpose
D. said she preferred the single state

What will power your house in the future? Nuclear wind or solar power? According to scientists at the Massachusetts Institute of Technology(MIT) in the US, it might be artificial leaves.
Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用). Now researchers have found a way to imitate this process.
The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts(催化剂). Similar to natural leaves, it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell (电池), using those two materials to produce electricity, located either on top of a house or beside the house.
Though the leaf is only about the shape of a poker card, scientists claimed that it is promising to be an inexpensive source of electricity in developing countries. “One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology” said an American scientist, Nocera.
An artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf, however, is made of cheap materials, easy to use and highly stable. In laboratory studies, Nocera showed that an artificial leaf could operate continuously for at least 45 hours.
The wonderful improvements come from Nocera’s recent discovery of several powerful new, inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now the new leaf is about 10 times more effective at carrying out photosynthesis than a natural one. Besides, the device can run in whatever water is available. This is important for some countries that don’t have access to pure water.
Hopefully, each home could have access to the new application in the future.
1.The purpose of this article is to ________.
A. introduce a new kind of device
B. ask people to do the research
C. advertise the new product
D. show the process of photosynthesis
2.Which of the following is NOT the advantages of the new leaf?
A. It’s low in cost.
B. It’s small in size.
C. It has a wonderful fuel cell.
D. It’s convenient for people to use.
3.What conclusion can be drawn from the text?
A. Nocera thought the new leaf is expensive for developing countries.
B. Villages in Africa have benefited a lot from the new invention.
C. Silicon chip can help the new leaf work more effectively.
D. The equipment doesn’t necessarily operate in pure water.
4.What’s the writer’s attitude towards the new device?
A. Negative.
B. Optimistic.
C. Doubtful.
D. Uncertain.
5.According to the text, what will take place in the future?
A. Natural leaves will take the place of artificial leaves.
B. Scientists will develop more ways to produce energy.
C. The new invention could be widely used in the future.
D. Developing countries will contribute more to the research.

I will never forget the day--- September 10th 2009, when my class went on a field trip to the beach and I had so much fun. When we returned to school, my teacher told me to go to the headmaster’s office. When I got into the office, I saw a police officer. Suddenly, I realized something was wrong. The police officer told me what had happened and we went to pick my sister up. After that, we went to the hospital and waited. Time went slowly. Finally, we got to see our mother. It was terrible.
On the next day, the headmaster came and told my two teachers what had happened. I was taking a test that day. I knew it had something to do with my mother. I kept thinking that she either died or had gotten better. How I wished that she had gotten better. When my teacher took me outside, my sister ran up to me. She started crying, “She’s gone, Terresa, mommy’s gone. She’s dead.” I couldn’t believe it. We jumped into the car and drove straight to the hospital. Most of my family were there. The silence was terrible. I knew I had to say goodbye.
Today when I look back, I still miss my mother very much, but I know that I will live. My mother was a strong mother, who had the biggest heart. She was an angel walking on the earth. I will always remember her as a living. When someone is asked who their hero is, they usually say someone famous, like Michael Jordan or Britney Spears. When someone asks me who my hero is, I tell them, my mother. My mother lives everyday. That is what makes her a true hero.
