And to do this, many of us make New Year’s resolutions---a list of ways ___12___ we intend to improve ourselves in the year ahead. We reflect on our past mistakes and make up our minds not to do them again. ___13___ (give) up smoking is ever popular, as is a promise to take up more exercise or spend more time with family.什么从句?But have you ever wondered when the idea of a New Year’s resolution comes from? The answer might lie in ancient Babylonia, according to History. com. The Babylonians ___14___ (believe) to be the first to hold recorded celebrations for the New Year. The 12 day-long celebration, ___15___ (name) Akitu, allowed them not only ___16___ (show) their loyalty to the King, but also to appeal to the gods to pay their debts and return the borrowed objects.The ancient Romans too had similar traditions. New Year’s Day was a time ___17___ all government officers would take an oath(发誓) that they ___18___ obey the laws and support the city leader. Incidentally, (顺便提一句) the month of January is named after the Roman god Janus. He is the god of beginnings, transitions and time, among other things and is described as having twofaces---one looking to the past and ___19___ facing forward to the future.Whether you’re looking at a quick behavioral change ___20___ a huge personality checkup, you’re taking part in a tradition that goes back centuries.

When I asked them how they decided what they wore that day, there was a(n) ___23___ moment of silence. It seemed a ___24___ silly question. A few just said “they wore what they wore.” This was a perfect beginning as it was the same kind of response they were giving as to how they were getting their math answers. I told them how I decided what I wore that day.First I checked the weather in the paper and by looking outside. I had to decide between wearing a dress or skirt since either could make a difference in the ___25___ I wish to give. Most of the girls relate d to(和…有关) this one.

Are you saying that the person has fast recall or that he or she ___31___ information quickly? Or maybe you just mean that the person remembers a lot about her or his childhood. The truth is that it is ___32___ to say exactly what memory is. Even scientists who have been studying memory for decades say they are still trying to ___33___ exactly what it is. But we do know that a particular memory is not just one thing stored somewhere in the brain. ___34___ , a memory is made up of bits and pieces(零碎东西) of information stored all over the brain. Perhaps the best way to ___35___ memory is to say that it is a process---a process of recording, storing, and getting back information. Practice and repetition can help to ___36___ the pieces that make up our memory of that information.Memory can be negatively affected by a number of things. ___37___ nutrition can affect a person’s ability to store information. Excessive alcohol use can also ___38___ memory and cause permanent ___39___ to the brain over the long term. A vision or hearing problem may affect a person’s ability to notice certain things, thus making it ___40___ to record information in the brain.When people talk about memory, they often ___41___ both short-term memory and long-term memory. If you want to call a store or an office that you don’t call often, you look in the telephone book for the number. You dial the number, and then you forget it! You use your short-term memory to remember the number. Your short-term memory lasts about 30 seconds, or half a minute. ___42___ , you don’t need to look in the telephone book for your best friend’s number, because you already know it. This number is in your long-term memory, which ___43___ information aboutthings you have learned and experienced through the years.Why do you forget things sometimes?

C 45. BSection B(22分)Directions: Read the following passages. Each passage is followed by some questions or unfinished statements. For each of them, there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Now, let’s talk about earthquakes on our planet. Some countries have large numbers of earthquakes. Japan is one of them. Others do not have many. For example, there are few earthquakes in Britain. There is often a great noise during an earthquake. The ground vibrates (震动). Houses fall down. Trains run off the lines. Sometimes, there is a heavy loss of human lives.Earthquakes often happen near volcanoes, but this is not always true. The centers of some earthquakes are under the sea. The bottom of the sea suddenly moves. The powerful forces inside the earth break the rocks. The coast is shaken and great waves appear. These waves, also known as seismic waves(地震波), or tsunamis(海啸) can travel long distances and rush over the land when they reach it. They are strong enough to break down houses and other buildings. Very often fires follow the most serious earthquakes. In 1906, the numbers of fires were burning in the city. The water pipes were also shaken and broken, so it was not possible to put the fire out. There was no water. The Tokyo Earthquake of 1923 happened just before noon. People were cooking meals on their fires at that time. When the ground shook, the fires shook, too. Hot materials were thrown on the different parts of the houses, some of which were made of wood. Soon 134 fires were burning in the city.What kind of building stands up best in an earthquake? A building with concrete walls is perhaps the best. A steel frame will make it even stronger. The frame holds the different parts together and the walls so not easily fall. There is less chance of fire because concrete and steel do not burn. Over the years, scientists studied the results of the earthquake in different parts of the world, and they are convinced that this kind of building is the safest.46. What can we know about earthquake from the first paragraph?A. Britain has large numbers of earthquake.B. There is often a great noise during an earthquake.C. There is a heavy loss of human lives in every earthquake.D. Trains will not run off the lines during the earthquake.47. Some of the undersea earthquakes were caused by ______.A. the breakout of the volcanoB. the seismic wavesC. the tsunamiD. the powerful forces inside the earth48. What can be inferred from the last paragraph?A. A building with concrete walls and a steel frame stands up best in an earthquake.B. There is no chance of fire in a building with concrete walls.C. Scientist studied the causes of the earthquake to get the conclusion.D. A steel frame has no help in making the house stronger.49.

C(C)The name of the race comes from the name of an Alaska gold rush town, Iditarod. It means “distant” or “distant place.” It comes from one of the languages of native Alaskans.More than sixty sled(雪橇) teams begin the race in Anchorage. When the teams reach the outskirts(郊外) of town, they get a taste of Alaska’s wilderness. For about two weeks, they will fight the unbearable cold, wind, snow, and ice to complete the race. The temperature on the trail is often well below zero degrees. The Iditarod trail extend s for about a thousand miles. It has many rendezvous points. (汇聚点) At these meeting places, the race teams “check in” to let the officials know how they are doing. Some teams get into trouble along the way. Officials will stop them and give them the help they need. For example, officials might stop a team’s progress to give first aid, or to collect an injured or tired dog. These dogs are well cared for and will be reunite d with their owners after the race.The Iditarod trail is an important part of Alaska’s history. A part of the trail was used by some heroic dogs and humans in 1925. In Nome, Alaska, many people were catching the deadly disease Diphtheria. (白喉) So the whole town was in quarantine, or isolation, in order to stop this disease. The only way to get medicine to Nome was by dogsled. About twenty "mushers, "or dogsled drivers, offered to help. They wanted to save the people of Nome from this terrible disease.Today the Iditarod race shows honors to this special heroic journey and to all of the journeys on the famous trail. As the race organizers say, the Iditarod is “the last great race on Earth.”53. Which of the following is TRUE about the Iditarod race?A. It is held every year in the downtown streets in Anchorage.B. It usually lasts about two weeks in freezing cold weather.C. It is held to honor the gold seekers who once lived in Iditarod.D. Its trail is totally different from the one used by some heroic dogs.54.

In his hand is a black leather bag. Zeng opens his bag, taking out two forms. ___57B___Each of the forms contains detailed information of a student. On his arrival two hours later, a woman greets him and leads him to her office where another man is waiting. They are the two village officials. They inspect the forms handed to them by Zeng and immediately recognize the girls. ___58C___ “It’s a pity but it doesn’t matter,” says Zeng, who wastes no time in deciding to look for the remaining child, Su Qinju.After half an hour, they stop outside a small house made of mud brick. A middle-aged man and a girl in a faded pink dress greet them. Su Qiuju is eight years old. She was forced to drop out ofschool after both her parents died. She is now living with her uncle who cannot afford his own children’s education.
