Cooking programs and classes for children seem to positively influence children's food preferences and behaviors，according to a recent review．And，although the review didn't look at long-term effects of such programs，the findings suggest that such programs might help children develop long-lasting healthy habits．
This research comes at a time when childhood obesity（肥胖） rates have been rising rapidly．More than one-third of adolescents in the United States were obese in 2012，according to the U．S．Centers for Disease Control and Prevention (CDC)．This trend has been caused，at least in part，by a significant decrease in the amount of meals that people consume at home since the 1980s，according to background information in the study．
Cooking education programs，such as Food Explorers，teach children about new healthy foods and how to prepare them．They also stress the importance of eating five fruits and vegetables every day．a volunteer parent explains a new food to the group，and the kids make something based on the lesson，such as fruit or vegetable salad． Depending on the program，kids may be sent home with information about healthy foods to bring to their parents，the review explained．
The study team reviewed eight other studies that tested different types of cooking education programs．Children in these classes were between 5 and 12 years old，according to the review．The goal of the study team was to learn more about developing an efficient program to encourage healthy food choices that last a lifetime．The study found that it is particularly important to expose kids to healthy foods on a number of occasions．This makes them feel comfortable with the new foods，which helps them build healthy habits．
The study stressed the importance of getting parents involved in（参与） their children's eating habits．Parents who are unable to enroll their kids in a cooking class can achieve similar benefits by having their kids help them while they prepare meals at home．Children are more comfortable at home，which makes them more receptive to new foods because they will make the connection to a positive experience．

| A．Eating out frequently causes obesity． |
| B．Childhood obesity is totally caused by eating habit． |
| C．Childhood obesity rates have been rising rapidly since 2012 |
| D．Food consumption has decreased significantly since the 1980s． |

The most complex object known to humanity is the human brain — and not only is it complex, but it is one of the few natural phenomena that science has no consciousness of. To try to replicate (复制) something that is so poorly understood may therefore seem like pride. But you have to start somewhere, and International Business Machines (IBM) and the Ecole Polytechnique Feder
ale de Lausanne (EPFL), in Switzerland, propose to start by replicating “in silico”, one of the brain’s building blocks.
In a partnership announced, the two organizations said they would be working together to build a simulation (模拟) of a structure known as a neo-cortical（新大脑皮质的）column on a type of IBM supercomputer that is currently used to study the molecular functioning of genes. If that works, they plan to use more powerful computers to link such simulated columns together into something that mimics（模仿) a brain.
In a real brain, a neo-cortical column is a cylindrical（圆柱形的）element about a third of a millimeter in diameter and three millimeters long. It is these columns, arranged side by side like the cells of a honeycomb, which make up the famous “grey matter” that has become shorthand for human intelligence. The Blue Gene/L supercomputer that will be used for the simulation consists of enough independent processors for each to be programm
ed to mimic an individual nerve cell in a column.
The EPFL’s contribution to the Blue Brain Project will be to create a digital description of how the columns behave. The database from its Brain Mind Institute will provide the raw material for the simulation. Biologists and computer scientists will then connect the artificial nerve cells up in a way that mimics nature. They will do so by assigning electrical properties（电能）to them, and telling them how to communicate with each other and how they should modify their connections with one another depending on their activity.
That will be no mean feat. Even a single nerve cell is complicated, not least because each one has about 10,000 connections with others. And nerve cells come in great variety—relying, for example, on different chemical transmitters to carry messages across those connections. Eventually, however, a digital representation of an entire column Should occur.
Assuming that the growth of computing power continues to follow Moore’s Law, the leader of IBM’s side thinks it should be practical to mimic an entire human brain in silico this way in ten to fifteen years. Such an artificial brain would, of course, be a powerful research tool. It would allow neurological experiments that currently take days in a “web lab” to be conducted in seconds. The researchers hope that their simulated brain will reveal the secrets of how certain psychiatric and neurological, disorders develop. But that is probably not the real reason for doing it. The most interesting question, surely, is whether such an artificial brain will be intelligent, or conscious, or both.In a real brain, a neo-cortical column ____________.
| A．looks like the cells of a honeycomb |
| B．is a simulation of a structure |
| C．is the famous grey matter |
| D．contains a large number of nerve cells |
What does the underlined sentence “That will be no mean feat” in Paragraph 5 indicate?
| A．It is rather difficult to connect the artificial nerve ceils up. |
| B．The function of chemical transmitters is hard to understand. |
| C．A digital representation of an entire column is time-consuming. |
| D．A single nerve cell is complicated to identify across connections. |
The fundamental purpose of doing the research is probably ____________.
| A．to simulate an entire human brain in silico |
| B．to tell us how some certain disorders emerge |
| C．to discover how the artificial brain would work |
| D．to examine whether Moores Law is still functioning |
What type of writing is this passage?

The slavery drama “12 Years a Slave” won the Academy Award for best picture on Sunday, making history as the first movie from a black director to win the film industry’s highest honor in 86 years of the Oscars. Britis
h director Steve McQueen’s brave portrayal of pre-Civil War American slavery won two other Oscars, including best supporting actress for newcomer Lupita Nyong’o and best adapted screenplay based on the memoir of Solomon Northup, a free man tricked and sold into slavery in Louisiana. “Everyone deserves not just to survive but to live. This is the most important legacy of Solomon Northup,” said McQueen in his acceptance speech.
“12 Years a Slave” was better over space thriller “Gravity” from Mexican filmmaker Alfonso Cuaron, which nevertheless got the most Oscars of the night with seven, including the best director honor for Cuaron, a first for a Latin American director.The film starring Sandra Bullock as an astronaut lost in space swept the technical awards like visual effects and cinematography, a reward for its groundbreaking work on conveying space and weightlessness. Referring to the “transformative” experience he and others undertook in the four-plus years spent making “Gravity”, Cuaron, whose hair is graying, said, “For a lot of these people, that transformation was wisdom. For me, it was just the color of my hair.” In one of the strongest years for film in recent memory, the 6,000-plus voters of the Academy of Motion Picture Arts and Sciences scattered golden Oscar statuettes among the many acclaimed movies in contention.
It was a good night for the scrappy, low-budget film “Dallas Buyers Club”, directed by Jean-Marc Vallee, a biopic of an early AIDS activist two decades in the making that won three Oscars, including the two male acting awards.
Matthew McConaughey, in a validation of a remarkable career turnaround, won best actor for his portrayal of the homophobe who turned AIDS victim and then turned treatment crusader Ron Woodroof, a role for which he lost 50 pounds (23 kg). His co-star, Jared Leto, won best supporting actor for his role as Woodroof’s unlikely business partner, the transgender woman Rayon, for which he also slimmed down drastically.
Australia’s Cate Blanchett won the best actress Oscar for her acclaimed role as the socialite unhinged by her husband’s financial crimes in Woody Allen’s “Blue Jasmine.” “As random and subjective as this award is, it means a great deal in a year of, yet again, extraordinary performances by women,” said Blanchett, who beat out previous Oscar winners Bullock, Amy Adams, Judi Dench and Meryl Streep.The film which won the largest number of Oscar awards this year is ______.
| A．12 Years a Slave | B．Gravity |
| C．Dallas Buyers Club | D．Blue Jasmine |
Which director spent the least money in making the film?
| A．Steve McQueen. | B．Alfonso Cuaron. |
| C．Jean-Marc Vallee. | D．Woody Allen. |
How many Oscar best actresses are mentioned in this passage?
| A．One. | B．Three. | C．Five. | D．Six. |
Which of the following statements is WRONG?
| A．12 Years a Slave won two Oscar awards altogether. |
| B．The director of Gravity is from Latin America. |
| C．The character Rayon is played by Jared Leto. |
| D．The woman film star Cate Blanchett comes from Oceania. |

Teaching your child to cook is not hard; the hard part could be getting them out of the kitchen. When you are teaching them, remember to stress safety and cleanliness, after all these are skills they will need for many years into the future.
Start by finding simple no-cook recipes. A salad or other no-cook recipe is an ideal way to start. Show your child how to hold, and cut with knives. Make sure they know how to wash everything in hot soapy water as they use it, so that it becomes a habit that is part of the process and not an extra chore to do after they have finished.
If possible, find one of the good children’s cookbooks that are available. Many of these have simple recipes that demonstrate the basic cooking terms such as chop, mix, and stir. When it is practical, you may as well have your child help you prepare meals. Even a small child can get bowls out, pour, and start learning to measure. A two- year -old child can stir a batter（面糊）, or taste the results.
Allow your older child to find a recipe that they think sounds nice. Go over the recipe with them as you discuss the steps needed, and how to adjust any ingredients to match your budget, and family preferences.
When you go shopping， have your child help find the necessary ingredients for their ‘special’ recipe. When it is time to make the recipe, allow them to do as much as possible, only helping out if asked or when they run into trouble. Be sure to praise their efforts even if they are not perfect. After the results are gone, talk about any problems, and see if there is a solution.
Most children like to cook, and if they are part of deciding what to cook, as well as the preparation they will be well on the way to being good cooks.The author wants to say in the passage that__________.
| A．it is a pleasure to cook with your children |
| B．children are eager to learn how to cook |
| C．parents should perform their duty |
| D．it is no good cooking with children |
Why should we tell children safety and cleanliness?
| A．Because children are often careless |
| B．Because we must keep them free of danger |
| C．Because they will develop good habits |
| D．Because they think cooing is hard |
What should you do when cooking is finished？
| A．Give praise in good time to your child. |
| B．Have a taste of what has been made. |
| C．Avoid mentioning any mistakes he/she made. |
| D．Help them out of any difficult situation. |
Dear Editor,
Recent reports have indicated an additional 1, 400 Marines（海军陆战队）are being sent to Afghanistan in the coming weeks. This means it costs over $1 million annually on the ground over there. I do place a higher level of blame on the policymakers who send soldiers off to kill and be killed in the field. I think the human race needs to think more about killing.
One needs to do the introspection: “Are these wars JUST?” I believe that all of our wars since 1945 have been illegal, under international law as well. I suggest that all your readers examine their conscience（良心）as it relates to the matter of making war. The fact that many soldiers are motivated by a strong sense of duty does not give them some unqualified moral right to support these wars or any other. It’s responsible for all the troops, and the entire population, to determine whether the Afghan or Iraq wars are in accordance with （符合）the development of the state.
I wish someone would give me one or more logical reasons why we are still fighting in Afghanistan and what our goals are. I certainly don’t understand it and neither do many who are more knowledgeable than I.
Outsiders have tried unsuccessfully for centuries to conquer Afghanistan, and we seem to be no more successful. We are trying to develop a stable central government, but the country is badly divided into ethnic and tribal groups, and the current government is corrupt（腐败的）. Moreover, we are apparently regarded as undesirable occupiers by many of its people, most notably the Taliban.（塔利班）
If we are to continue spending billions every year in Afghanistan and killing hundreds of our people and many of theirs, our government must provide us with a reasonable explanation of why we are doing so and what we can expect to accomplish.
George MyersWhat caused the author to write the letter?
| A．His conscience of being a citizen. |
| B．Reports about sending soldiers to Afghanistan. |
| C．His relatives being killed in the war. |
| D．Getting no reasonable explanation. |
The underlined word “introspection” in the passage means .
| A．self-awareness | B．self-confidence |
| C．self-examination | D．self-defence |
The soldiers go to Afghanistan because .
| A．they can contribute to the development of America |
| B．they have the moral right to do so |
| C．they are performing their duty as a resident |
| D．they want to become heroes in the war |
Which of the following is NOT true according to the passage?
| A．Most people can’t understand why the States makes wars. |
| B．The U.S.A has developed a stable central government. |
| C．The Afghan considered Americans as undesirable occupiers |
| D．American government should make an explanation to the public. |
