Most kinds of rose plants come from Asia. But roses are also native to other areas including northwest Africa, Europe and the United States. In 1986, Congress chose the rose as American’s national flower. Technically, Congress and President Ronald Reagan declared it the “national floral emblem（国花）.” Whatever the name, the decision did not smell sweet to supporters of other popular flowers.
Some people say roses are difficult to grow. But you have a good chance of success if you start with a few suggestions from experts. You should plant your roses where they can get sunshine for about six hours on bright days. You can buy roses from a garden center or by mail order. You can buy potted roses, also known as container roses, or bare-root plants. Each kind has its fans.
Some gardeners say potted roses are easier to plant. They say the roots develop better. But Jeffrey Dinslage, an expert, points out that bare-root roses come without soil. So they weigh less to transport.
Another expert advises getting bare-root roses as close to planting time as you can.. If they arrive before you are ready to plant them, make sure the packing material is moist. Keep the plants in a cool, dark place. The resting plants have no leaves but still need water. When growing roses, the soil should feel moist deep down. Watering should be done in the morning.
But do not water too much. People often ask Jeffrey Dinslage about unhealthy discoloration on rose leaves. He says the spots are usually caused by too much water. After heavy rains or too much watering, he advises pulling away mulch, the substance used to protect the roots, to improve the quality of the soil, temporarily from around the roots. This will help dry the soil.From the first paragraph, we know that in the United States _______.

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 leaves-but artificial（人造的）ones.
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 seemingly simple 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, which uses 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 Nocera at a conference of the American Chemical Society.
The 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, by contrast, is made of cheap materials, easy to use and highly stable. In laboratory studies, Nocera showed that an artificial leaf prototype （原型）could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera's recent discovery of several powerful, new and 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 efficient at carrying out photosynthesis than a natural one. Be-sides, the device can run in whatever water is available; that is, it doesn't need pure water. This is important for some countries that don't have access to pure water.
With the goal to " make each home its own power station" and" give energy to the poor"，scientists believe that the new technology could be widely used in developing countries, especially in India and rural China. Which of the following orders correctly shows how the artificial leaf is used to produce electricity?
a. artificial leaves split water into hydrogen and oxygen
b. the hydrogen and oxygen gases are stored in a fuel cell
c. the artificial leaves are put in water
d. the fuel cell uses hydrogen and oxygen to produce electricity
| A．c, b，a, d |
| B．c, a，b, d |
| C．b, c，a, d |
| D．c, a，d, b |
The purpose of the scientists at MIT in developing the new artificial leaf is to __________.
| A．build up more power stations in the world |
| B．provide cheaper energy for developing countries |
| C．offer people in developing countries access to pure water |
| D．gain a deeper understanding of the photosynthesis process |
The main idea of this passage is __________.
| A．an introduction to the history of artificial leaves |
| B．an invention copying photosynthesis |
| C．giving energy to the poor |
| D．mixture of water power and solar energy |
The underlined word " imitate" in Paragraph 2 can be replaced by "__________".

| B．hold |
| C．prevent |
| D．copy |
Today, we complete our story about the influential English writer William Shakespeare. He wrote plays and poems during the late fifteenth and early sixteenth centuries, which remain very popular today.
During earlier times, people would probably have learned several ancient Roman and Greek plays. It was not unusual for writers to produce more current versions of these works. For example, in Shakespeare’s play “The Comedy of Errors”, Shakespeare borrowed certain details from the ancient Roman writer Plautus. For his play “Macbeth”, Shakespeare most likely used a work on Scottish history by Raphael Holinshed for information. Shakespeare might have borrowed from other writers, but the intensity（强度）of his imagination and language made the plays his own. While many plays by other writers of his time have been forgotten, Shakespeare and his art live on.
Shakespeare was also influenced by the world around him. He described the sights and sounds of London in his plays. His works include observations about political struggles, the fear of diseases, and the popular language of the city’s tradesmen. Shakespeare’s knowledge of the English countryside is also clear. His works include descriptions of deep forests, local flowers, and the ancient popular traditions of rural people.
It would be impossible to list all of the ways in which Shakespeare’s works have influenced the world culture. But the first and greatest example would be his great influence on the English language. During his time, the English language was changing. Many new words from other languages were being added. Shakespeare used his sharp mind and poetic inventiveness to create hundreds of new words and rework old ones. For example, he created the noun forms of “critic”, “mountaineer” and “eyeball”. Many common expressions in English come from his plays, including “pomp and circumstance（装腔作势）” from “Othello”, “full circle（绕圈子地）” from “King Lear”, etc. The list of cultural creations influenced by Shakespeare is almost endless. From paintings to television to music and dance, Shakespeare was well represented. Shakespeare’s plays have been translated into every major language in the world.
Shakespeare became a wellknown writer during a golden age of theater. His years of hard work paid off. From the passage, we can see that ________.
| A．Shakespeare was hardworking when he was a student |
| B．many of Shakespeare’s works were influenced by earlier writings |
| C．the experience of living in London had no effect on Shakespeare’s works |
| D．Shakespeare became rich later because of the popularity of his works |
Why could Shakespeare’s works survive his time?
| A．Because there were so few people writing plays in his time. |
| B．Because he produced too many works that nobody else could do. |
| C．Because his works were rich in imagination and language. |
| D．Because he was a rich and influential person of his time. |
Shakespeare’s greatest influence should be on .
| A．paintings |
| B．television |
| C．the English language |
| D．music and dance |
The passage is mainly about .
| A．an introduction to Shakespeare’s life and his works |
| B．the main features and styles of Shakespeare’s plays |
| C．Shakespeare’s greatest influence on the world culture. |
| D．how culture influenced Shakespeare and he influenced culture. |
I was reading these interesting stories behind a group of great logos in the world. Personally Nike is my favorite one – it’s so simple. And I liked the stories behind them, which made me forget all other things. McDonald’s, Apple, Mercedes Benz and Adidas own great logos as well, and they are among my favorites.
Nike
In the Greek myth, Nike is the goddess of victory and the source of inspiration for soldiers. This logo represents the wing in the famous statue of the Greek goddess. Nike’s logo was designed by Carolyn Davidson in 1971 for $ 35, and was registered as a trademark in 1995.
McDonald’s
The logo was designed in 1962 by Jim Schindler to resemble the archshaped(拱形的) signs on the side of the company’s then walk-up hamburger stand. Later on, the two golden arches were combined together to form the M. The McDonald’s name was added to the logo in 1968.
Apple
There are different stories behind Apple’s logo. The first logo was a reference to the religious story of Adam and Eve, in which the apple represented the fruit of the Tree of Knowledge. One year later, the second logo was designed in 1977 by Steve Jobs and Ronald Wayne, and it described Sir Isaac Newton sitting under an apple tree. This logo didn’t stay long. One year later it was replaced almost immediately by graphic designer Rob Janoff’s “rainbow apple”, a rainbow-colored silhouette(轮廓)of an apple with a bite taken out of it. And then the rainbow-colored apple was replaced by the one-colored logo in 1998. It has not been changed so far.
Mercedes Benz
The Mercedes Benz logo, which was originally created by Gottlieb Daimler in 1909, consists of a simple description of a three-pointed star that represents its rule of the land, the sea and the air. The company was founded by Gottlieb Daimler and Wilhelm Maybach. Mercedes is the name of Maybach’s elder daughter, while Benz came as a result of a combination with Benz, Cie and DMG in 1926.
Adidas
The Adidas logo, which was created by the founder of the company Adi Dassler, represents mountains, pointing towards the challenges that are seen ahead and goals that can be achieved. The logo was used for the first time in 1967.What does the author think of the stories of the great logos?

| D．Nike– McDonald’s – Apple – Mercedes Benz. |
Despite the fact that it has never been seen almost everyone is familiar with the legendary unicorn(独角兽). Descriptions of unicorns have been found dating from ancient times. The great philosopher Aristotle theorized that there were two types of unicorn--- the so-called Indian Ass and the Oryx, a kind of antelope. Unicorns are often used in the logo of a noble family, town council or university as their special sign. Even Scotland is represented by a unicorn.
According to the legend, anyone attempting to catch a unicorn had to be extremely careful as it was very fierce and dangerous. A clever trick suggested by unicorn-trappers, in order to catch this amazing animal without being hurt by its horn, was for the hunter to stand in front of a tree and then to move quickly behind it as the unicorn dashed angrily. Hopefully, the creature could then be caught when its horn was stuck in the tree.
When hollowed out and used as a drinking-cup, the unicorn’s horn was said to have the power to offer protection against person. It was believed that nobody could be harmed-by drinking the contents of a unicorn’s horn. Right up until the French Revolution in 1789, the French court was said to have used cups made of “unicorn” horn in order to protect the king. In addition, the horn was said to have medicinal value, so much so that it could be sold for more than ten times the price of the same weight of gold. What, then, was “unicorn” horn? We know at times the rhino was confused with this legendary creature. A drinking-cup supposedly made of “unicorn” horn was discovered to be made of the horn of a rhino.Which of the following is TRUE of the unicorn?
| A．It was not historically recorded. |
| B．Its horn was first used in France. |
| C．It was similar to the Indian Ass and the Oryx. |
| D．It could be the symbol of a university. |
To catch a unicorn, the unicorn-trappers had to try all of the following EXCEPT ____.
| A．attracting the unicorn to attack |
| B．making use of the tree as a defense |
| C．hiding quickly behind the unicorn |
| D．having the unicorn horn stuck in the tree |
The last paragraph is mainly about ____.
| A．the functions of the unicorn horn |
| B．the users of the unicorn horn |
| C．the price of the unicorn horn |
| D．the comparison between the unicorn horn and the rhino horn |
In the last paragraph, the word “unicorn ” is in quotation marks (引号)because _____.
| A．the cup is designed only for a royal family |
| B．the unicorn does not exist in reality |
| C．the unicorn is the rarest animal in the world |

There was a tradition in Europe that if a dove flew around a house where someone was dying then his soul would be at peace. And there are legends which say that Satan (撒旦) can turn himself into any bird except for a dove. But it was Pablo Picasso who made the dove a modern symbol of peace when he used it on a poster for the World Peace Congress in 1949.
The rainbow is another ancient and universal symbol, often representing the connection between human beings and their gods. In Greek mythology(神话) it was associated with Iris, the goddess who brought messages from the gods on Mount Olympus. In Scandinavian mythology the rainbow was a bridge between the gods and the earth. In the Bible a rainbow showed Noah that the Biblical flood was finally over, and that God had forgiven his people. In the Chinese tradition, the rainbow is often taken as a common symbol for marriage.
Nowadays the rainbow is used by many popular movements for peace and the environment, representing the possibility of a better world in the future and promising sunshine after the rain.
The olive tree has always been a valuable source of food and oil. In Greek mythology, the goddess Athens gave the olive tree to the people of Athens who showed their thanks by naming the city after her. But no one knows for sure when or why it began to symbolize peace. There is probably a connection with ancient Greece. The winners of the Olympic Games were given crowns (冠) of olive branches. The symbolism may come from the fact that the olive tree takes a long time to produce fruit, so olives could only be grown successfully in long periods of peace. Whatever the history, the olive branch is a part of many modern flags symbolizing peace and unity. One well-know example is the United Nations symbol. Which of the following is the most important in making the dove a modern symbol of peace?
| A．Greek mythology |
| B．The European tradition |
| C．Ancient legends |
| D．Pablo Picasso |
How many examples does the writer give to show the rainbow as a universal symbol of peace?

| A．it represents hope in the future |
| B．it has economic value for the world |
| C．it often gives prizes to countries |
| D．its duty is to keep peace and union |
