One of the most popular activities enjoyed by Americans is spending time in forests and walking along paths through the country.This activity，called hiking，has led to the creation of paths throughout the United States.
One of the longest is the Appalachian National Scenic Trail.The trail is the first completed part of the National Trails System.The trails system was established by Congress and the president in 1968.The Appalachian Trail is more than 3,400 kilometers long.It starts in the northeastern state of Maine and ends in the southeastern state of Georgia.The trail goes through 14 states.They are Maine，New Hampshire，Vermont，Massachusetts，Connecticut，New York，New Jersey，Pennsylvania，Maryland，West Virginia，Virginia，Tennessee，North Carolina，and Georgia.
The path takes walkers through the Appalachian Mountains.They extend from the Canadian province of Quebec to the southern American state of Alabama.
The Appalachian Mountains are among the oldest on Earth.They first began forming about one thousand million years ago.During the millions of years since then，the mountains were changed and reformed by the forces of water and wind.Ice also changed the mountains，making many of them smaller and digging valleys and lakes among them.Many different kinds of trees grow along the trail.And many different kinds of animals live in the forests along the trail.
Lands along the trail are protected by the federal government and by state governments.Some parts are not protected by the government directly.Instead，they are protected by legal agreements with private owners willing to permit people to walk across their property.
Walkers on the Appalachian Trail pass through some of the great valley systems of the mountains.They can look down into these beautiful valleys and see farms and forests stretching across the land for many kilometers.Farmland in the valleys is rich and productive.And some of the great events in American history took place in the valleys.For example，one of the great battles of the American Civil War was fought in the Shenandoah Valley in Virginia.

With 10, 600 bicycles in circulation，Paris city officials are hoping the program will provide people with more environmentally friendly transportation．
It seems both Parisians and tourists are taking advantage of the program．Since its launch a little over two weeks ago，Vélib has already seen almost half a million rentals．And，with the addition of 10，000 more bikes and 700 more stations in the next 12 months，city officials expect at least 200，000 regular users by year end．
Parisian Olivier Bioret has already gone for a spin on one of Vélib’s vehicles and plans to make use of them more often．
“It’s a real pleasure—when，like me，you don’t have space enough in your flat to have your
own bike—to be able to discover．to cross Paris and not have to take the subway，”he said．
As a socialist and longtime green activist，Mayor Bertrand Delanoe regards Vélib as just a part of his plan to reduce car traffic and，thus，lower pollution by 2020．
Apart from its environmental benefits，Vélib is also being praised as a way of collecting money for the city，for all the money from rentals goes to the city government．
Paris is not alone in its attempt to profit from the power of the bicycles．
Across the globe，cities such as Barcelona，which stated its bike-share program in March with 1,500 vehicles and 100 stations，and New York，which launched a five-day trial program last month，are using bicycles as a way to cut back on both traffic and pollution．
However，it remains to be seen whether people’s acceptance of these programs is simply a
passing fashion or whether this movement has the power to take root and transform the face of public transportation around the world．
【小题1】The real purpose of Vélib is________．
| A．to help people save money and space |
| B．to make some money for the city government |
| C．to provide convenience to both Parisians and tourists |
| D．to reduce traffic and pollution in the city |
| A．There will be 700 stations in one year’s time． |
| B．There will be over 20, 000 bikes in use in a year． |
| C．In the first two weeks there were nearly a million rentals． |
| D．There will be 200, 000 regular rentals each day by year end． |
| A．other cities also have such programs |
| B．Parisians can use the bicycles free of charge |
| C．Paris sets an example to many other cities |
| D．Paris is the first city to start such a program |

Around the world coral reefs(珊瑚礁) are facing threats(威胁) brought by climate change and great changes in sea temperatures. While ocean warming has been the primary focus for scientists and ocean policy managers, cold events can also whiten corals. A new study by scientists compared damaged to corals exposed to heat as well as cold stress. The results show that cool temperatures can cause more damage in the short term, but heat is more destructive(破坏性的) in the long run.
Climate change is widely known to produce warming conditions in the oceans, but extreme cold-water events have become more frequent and serious as well. In 2010, for example, coral reefs around the world faced on of the coldest winters and one of the hottest summers on record.
During a unique experiment, corals under cold temperatures suffered greater damage in just days compared with heat treated corals. Yet the researchers found that corals were eventually able to adjust to the cold conditions, make their health stable and continue to grow. However, over the long term corals subjected to heat suffered more greatly than those in cold, with evidence of severe whitening and growth stoppage, which leads to death.
The coral’s ability to adjust to cool temperatures surprised the researchers, who say the study’s results show the complexities(复杂性) of monitoring coral health in response to different environmental factors(因素).
“Global warming is associated with increases but also decreases of temperatures,” said Deheyn, one of the researchers. “Not much has been known about the comparative effects of temperature decrease on corals. These results are important because they show that corals react differently to temperature differences, which is important for future management of coral reefs in the field of climate change.”
【小题1】Which of the following is TRUE according to the passage?
| A．Corals are unable to adjust to temperature changes. |
| B．Cold temperature causes greater damage to corals. |
| C．Hot temperature helps coral reefs to grow quickly. |
| D．Heat and cold damage corals in their own ways. |
| A．scientists used to pay no attention to the effect of cold events on corals |
| B．2010 witnessed one of the greatest temperature differences on record |
| C．corals prefer warmer conditions to cold temperatures in the long run |
| D．global warming has nothing to do with the decrease of temperature |
| A．corals may continue to grow in cold events after a few days |
| B．cold events help corals grow more quickly in a short time |
| C．corals show no response to hot temperatures in the first days |
| D．corals are whitened mainly because of warm temperatures |
| A．news report | B．scientific study | C．great imagination | D．natural conditions |

“The first and best of victories is for a man to conquer himself; to be conquered by himself is, of all things, the most shameful，” says Plato. Selfcontrol is at the root of all the advantages. Let a man give in to his impulses (冲动) and feelings, and from that moment he gives up his moral (道德上的) freedom.
A single angry word has lost many a friend. When Socrates found in himself any temper or anger, he would check it by speaking low in order to control himself. If you are conscious of being angry, keep your mouth shut so that you can hold back rising anger. Many a person has dropped dead in great anger. Fits of anger bring fits of disease. “Whom the gods would destroy they firstmake mad” “Keep cool”， says George Herbert, “for fierceness (狂怒) makes error a fault.”
To be angry with a weak man is to prove that you are not strong yourself. “Anger，” says Pythagoras, “brings with folly(愚蠢) and ends with regret.” You must measure the strength of a man by the power of the feelings he conquers, not by the power of those which conquer him.
Selfcontrol is man's last greatest victory.
If a man lacks selfcontrol he seems to lack everything. Without it he can have no patience, no power to govern himself; he can have no selfconfidence, for he will always be controlled by his strongest feeling. If he lacks selfcontrol, the very backbone and nerve of character are lacking also.
【小题1】What does the reader learn from the first paragraph?
| A．The greatest victory for a man is to conquer everything except himself. |
| B．One's moral freedom is based on the control of himself. |
| C．To control oneself is the most difficult in one's life. |
| D．If a person is too stubborn, he will feel most shameful. |
| A．If the gods want to kill you, they make you crazy first. |
| B．If you cannot control yourself, you will become crazy. |
| C．If you always lose your temper, you will soon be finished. |
| D．If you are mad, you will be punished by the gods. |
| A．the very backbone and nerve of character |
| B．the patience and power to control himself |
| C．selfconfidence |

Popeye the Sailor first became a popular cartoon in the 1930s. the sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.
【小题1】A good title for this reading passage is______.
| A．Popeye the Sailor |
| B．The Truth About Spinach |
| C．A Mistake with Numbers |
| D．Folic Acid Makes You Strong |
| A．People liked folic acid. |

Every electronic gadget (小玩意) needs good memory. A music player stores songs, albums and playlists. A computer holds schoolwork and programs and remembers how far a player has advanced in his or her favorite game. Mobile phones store names, numbers and hundreds of texts.
Now, scientists in California say they have come up with a way to turn a living cell into a memory device.
It can store only one tiny bit of information, but it’s a start. In the future, a cell-based gadget might travel through the body and record measurements. The benefit to human health could be big: the right tool, for example, might record the earliest signs of disease.
Doctors, scientists and other curious people want to know what is happening inside the body, even at levels that can’t be seen by the naked eye. So far, there is no device small enough to travel through the bloodstream.
If normal machines won’t do the trick, perhaps biology will. Scientists who work in the field of synthetic (合成的) biology are trying to find ways to turn living things into human tools. In the case of the new memory device, bioengineers from Stanford University used the genetic material inside living cells to record information.
This genetic material consists of DNA. Found in nearly every cell, DNA carries all of the information that keeps a living thing alive.
In the new experiment, the researchers turned DNA from bacteria(细菌) into a switch. They “flip (翻转)” a small section of DNA. Then, using the same procedure (过程) , the scientists flip the section again—returning it into its normal structure.
Using these DNA switches, “We can write and erase DNA in a living cell,” bioengineer, Jerome Bonnet, explained to Science News.
It might take years before his team or others identity whether a DNA-based memory device might be practical. Right now, it takes one hour to complete a flip. That is far too long to be useful. Plus, a flipped section has a very small little memory—less than what a computer uses to remember a single letter.
“This was an important proof that it was doable,” Bonnet told Science News. “Now we want to build a more complex system, something that other people can use.”
【小题1】What is the aim of listing the electronic things in the first paragraph?
| A．To make the passage more fashionable. |
| B．To show how electronic things have memory. |
| C．To discuss things in detail. |
| D．To make the subject of the text more understandable. |
| A．To detect disease at the earliest point. |
| B．To help improve the memory. |
| C．To help people build a body. |
| D．To replace many electronic gadgets. |
| A．It has a very small memory. |
| B．It can function as a computer. |
| C．It has one letter in it. |
| D．It takes a day to complete it. |
