Organic food, once considered something that only health fanatics desired, is now a regular feature at most supermarkets. And that has created a bit of a dilemma. On the one hand, you have a conventionally grown apple. On the other, you have one that’s organic. Both apples are firm, shiny and red. Both provide vitamins and fiber, and both are free of fat, sodium and cholesterol.
Conventionally grown food generally costs less, but is organic food a better choice? The advantages claimed for such foods over conventionally grown and sold food products are now being debated on a large scale. Supporters of organic foods ― a term whose meaning varies greatly ―are frequently telling the world that such products are safer and more nutritious than others.
The growing interest of consumers in the safety and nutritional quality of daily foods is a welcome development. However, much of this interest has been aroused by sweeping claims that the conventional food supply is unsafe or inadequate in meeting nutritional needs.
Almost daily, the public is surrounded by claims for “no-aging” diets, new vitamins and other wonder foods. There are numerous unsubstantiated(没证实的) reports that natural vitamins are superior to man-made ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than those treated with insect spray and the like.
Although most of these claims are not supported by scientific evidence, large amounts of written material about the benefits of organic foods makes it difficult for people to separate fact from fiction. As a result, claims that eating a diet consisting of organically grown foods prevents or cures disease or provides other benefits to health have become widely advertised and form the basis for people’s opinion.
One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern if consumers, particularly those with limited incomes, distrust the conventional food supply and buy only expensive organic foods instead.

Since the beginning of the year, smog has covered parts of North China. In January, Beijing saw only five days without smog. The rising PM 2.5 readings terrified many people, and some health experts said that whenever the smog gets serious, hospitals receive more patients suffering acute respiratory(呼吸系统)and heart diseases.
Later, news of polluted underground water in some provinces scared people who wondered whether the water they drink is safe.
So the need to emphasize environmental protection while developing the economy is heard everywhere.
Smog especially is a common concern. Like a popular online post said, air may be the only thing that is equal for everyone, despite your income or vocation. People with higher incomes are able to drink only bottled spring water and eat only organic food by paying higher prices, but they breathe the same air as everyone else.
At a meeting on Monday, many Representatives have expressed their concerns about the air quality, too. One talked about his experience in Beijing. “After taking a taxi from the capital airport to my hotel, which took about an hour, I washed my nose and found the inside of my nose was black. We should ask ourselves this question: Why do we want to develop? It's for living a better life. Dirty air is definitely not a better life," he said.
China needs to develop its economy and invest(投资) in high-tech. Every Chinese wants a strong country. But without blue sky, clean water and safe food, the achievements in the economy will become meaningless. Space technologies are not to be developed for building a base on Mars so that one day all human beings can migrate to the red planet because they have destroyed Earth.
What the public wants is a strong and beautiful China. Former president Hu Jintao spoke at the 18th Party Congress last November saying that great efforts must be made to promote ecological progress and build a beautiful China. The words have shown the central government's resolution to address the environment issue.
【小题1】The effect of smog doesn’t include.
A.the rising of PM 2.5 readings |
B.more people suffering diseases |
C.the increase of people’s income |
D.patients increased in hospital |
A.Because people have to pay higher prices. |
B.Because nobody can avoid it. |
C.Because we have to develop industry. |
D.Because a popular online-post discussed it. |
A.human beings | B.other plants |
C.space technologies | D.industrial development |
A.high-tech can completely solve the problem of pollution |
B.space technologies should be developed in a large scale |
C.we can move to the Mars after the earth has been destroyed |
D.we must protect the environment while developing economy |

Sixty-five million years ago, an asteroid (小行星) that crashed on Earth led to the disappearance of the largest animals that have ever walked our planet – the dinosaurs. At least, this is what some scientists believe. But that accident happened so long ago. People have come to believe that we are free of threats from asteroids and everything else from space.
However, what happened on Feb 15 , 2013 was a reminder that we’re just as vulnerable as the dinosaurs once were. Two objects from space – a meteor (陨石) and an asteroid called 2012 DA14 – visited Earth’s atmosphere on the same day. The former fell in Russia, injuring 1,200 people, while the latter passed by Earth at a record-setting close distance.
Scientists had been expecting the asteroid since last year, but the meteor was a surprise. NASA’s telescope system only detects asteroids at least 50 meters in diameter (直径), which is just about the size of 2012 DA14. But the meteor was much smaller, which made it harder to spot.
But what if we do spot an asteroid that is headed right for Earth? There are several possible ways in which dangerous asteroids could be made to change its orbit. Which method is best depends on several factors and most importantly – how much time we have to stop it.
If there is enough time before the hit, we can send off a heavy spacecraft to travel alongside the asteroid. The gravity from the spacecraft would gradually change the rock’s orbit. Besides that, scientists could one day use sun-powered lasers to either make asteroids disappear or change their course. If there’s not enough time, we’ll have to go after the asteroid with a spacecraft and change its orbit with a crash. Finally, if things are truly desperate, there will be only one choice left – to use a nuclear bomb. That could turn the asteroid into a meteor shower, which would be even more dangerous.
【小题1】The author mentioned the asteroid that led to the dinosaurs’ dying out to ______.
A.show that asteroids fall from space frequently |
B.alert people about the possible danger of objects falling from space |
C.inform readers about the constant threats the Earth faces |
D.suggest that there are still many mysteries about the universe |
A.unprotected | B.lonely | C.stupid | D.self-important |
A.It passed by the Earth at a close distance. |
B.It was spotted by NASA’s telescope system a year ago. |
C.It is about the same size as the asteroid that passed by the Earth. |
D.It fell to the Earth and caused great damage to the local community. |
A.Learning about asteroids and meteors. |
B.The threats of objects from space and possible solutions. |
C.NASA’s latest technology to discover visitors to the Earth from space. |
D.How to measure the damage of collisions from asteroids and meteors. |

About twenty of us had been fortunate enough to receive invitations to a film-studio(影棚)to take part in a crowd-scene. Although our "act" would last only for a short time, we could see quite a number of interesting things.
We all stood at the far end of the studio as workmen prepared the scene, setting up trees at the edge of a winding path.Very soon, bright lights were turned on and the big movie-camera was
wheeled into position. The director shouted something to the camera operator and then went to speak to the two famous actors nearby. Since it was hot in the studio, it came as a surprise to us to see one of the actors put on a heavy overcoat and start walking along the path. A big fan began blowing tiny white feathers down on him, and soon the trees were covered in "snow". Two more fans were turned on, and a "strong wind" blew through the trees. The picture looked so real that it made us feel cold.
The next scene was a complete contrast(对比).The way it was filmed was quite unusual. Pictures taken on an island in the Pacific were shown on a glass screen. An actor and actress stood in front of the scene so that they looked as if they were at the water's edge on an island. By a simple trick like this, palm trees, sandy beaches, and blue, clear skies had been brought into the studio!
Since it was our turn next, we were left wondering what scene would be prepared for us. For a full three minutes in our lives we would be experiencing the excitement of being film ”Stars”!
【小题1】Who is the author?
A.A cameraman. | B.A film director. |
C.A crowd-scene actor | D.A workman for scene setting |

Who is the most powerful woman in the world? According to the US media, it's Janet Yellen, or at least she's about to be.
On Oct 9, 2013,US President Barack Obama nominated (提名)Yellen to serve as the next US Federal Reserve (the Fed, 美联储)chair. If confirmed by the Senate, Yellen will become the first woman to serve in the top spot.
Aged 67, silver-haired and tiny, Yellen is said to be the most qualified nominee ever. She chaired President Bill
Clinton's Council of Economic Advisers, taught at Harvard and Berkeley, and was president of the Federal Reserve Bank of San Francisco. She is currently the Fed's vice chair.
Many think Yellen is the right choice to deal with the challenges the Fed now faces:First, to bring interest rates back to more normal levels without triggering a new recession(衰退).Second, to reduce the US unemployment rate, which remains at historically high levels.
A CNN opinion piece says Yellen is unusual for an economist of her caliber(才干)."She has kept her eyes on what's critical-the people. Her research has centered on unemployment, on the best way to modulate(调整)government policies to benefit the people."
Past records also show that Yellen is exceptionally good at predicting where the economy is headed. An article in The Washington Post points out that she was one of the few voices at the Fed inDecember 2009 warning about the subprime crisis(次贷危机)and the following recession.
The reason why Yellen will be the most powerful woman in the world has to do with the unique position of the Federal Reserve, explains an article on Quartz, a US news outlet for business people in the new global economy,
First of all, the Fed is independent. Unlike US Secretaries of State Madeleine Albright and Hilary Clinton, the decisions made by the organization Yellen will lead next year are not subject to approval by anyone in the government.
Within the Fed, the chair alone sets the agenda. The Fed chairperson has huge influence on monetary policy(货币政策)and financial regulation. And don't forget how powerful the Fed itself is. It controls the money supply in the world's largest economy. The Fed's interest rate decisions don't just set the course for the US economy, its decisions set the course for the world economy, too.
Because of globalization, Yellen's decisions will affect everyone around the world, says an article in The Atlantic, making her even more powerful than some great women rulers in history, including Elizabeth I of England and China's Wu Zetian. For example, the article continues: "If Yellen even just talks about slowing down the Fed's bond-buying, Europe's troubled economies are likely to see their interest rates rise, and emerging markets, some of which, like India and Indonesia, used foreign capital to fund their current account deficits(赤字),are likely to see their currencies collapse."
【小题1】According to the passage, which of the following is NOT the reason for Yellen's nomination?
A.Yellen's professional experiences. |
B.Yellen's ability to deal with the challenges the Fed faces. |
C.Yellen's educational background. |
D.Yellen's remarkable competence as an economist. |
A.the Fed is the most powerful organization in the US |
B.Yellen gets full support from Obama |
C.Yellen holds a unique position in the government |
D.the Fed possesses great power and influence |
A.Optimistic. | B.Negative. |
C.Understanding. | D.Doubtful. |
A.To introduce the US Federal Reserve. |
B.To report on the next Fed chair. |
C.To introduce the current world economy. |
D.To report on a few powerful women. |

Scotland is a unique place, loaded with history, where you can find aristocratic(贵族的)palaces and castles, as well as the traditional parades in national costumes.
In order to see and discover the true soul of Scotland today and what formed the character of this splendid region, we have to go towards the northern regions, to the Grampian Mountains(格兰扁山区), beautiful and plain. The Scots conquered the environment with simple spades and strong arms, for it was difficult to farm.
The history of this ancient struggle, and its people’s ancient love with the hard land, can be felt within the walls of the Angus Folk Museum. You are able to get a feel of the typical rural atmosphere of times past from the everyday artifacts displayed here.
From coastal Aberdeen in towards the Grampian Mountains there runs the Castle Trail, a road that touches on many fortresses(堡垒), which are witnesses of continual fights against the control of neighboring England in Scottish history.
Perhaps the most exciting moment for Scottish autonomy is the one experienced inside this ancient church of Arbroath, where, in 1320, the Declaration of Independence was celebrated, at the instigation(鼓动)of King Robert the Bruce. He carried out the plan for autonomy drawn up by the great popular hero William Wallace, for whom cinema has designed the wonderful film Brave Heart, the winner of the five Oscars.
This is Glamis Castle, where King Macbeth and Queen Elizabeth used to live. Among the most frequent guests here are the predictable ghosts, if not actually created, by ancient popular beliefs. These have been handed down over the centuries by people tending to live with mystery, with the forces of the supernatural.
Another attraction here is a legendary monster: the Loch Ness Monster. Whether it’s real or imaginary, this monster, which has been nicknamed Nessie, has collected a good 3,000 sightings over the last 50 years.
The true flag of Scotland, tartan, is recognizable from the brightly colored plaid patterns which are used to distinguish the various social groups.
Bagpipes and dancing open the competitions of local sporting events, which are called Highland Gatherings.
【小题1】Take a look at the Angus Folk Museum, and we can learn about _______. .

The fourth-graders at Chicago’s McCormick Primary School are unaware of the difficulty in learning Chinese. For most, who speak Spanish at home, it’s becoming their third language. They’ve been learning and using Chinese words since kindergarten, and it’s now second nature to give a hearty “ni hao” when strangers enter the classroom.
The classroom scene at McCormick is unusual, but it may soon be a common fixture(固定物) in American schools, where Chinese is rapidly becoming the hot new language. Government officials have long wanted more focus on security—useful languages like Chinese, and pressure from them—as well as from business leaders, politicians, and parents—has driven a quick growth in the number of programs.
Chicago itself is home to the largest effort to include Chinese in US public schools. The program here has grown to include 3,000 students in 20 schools, with more schools on a waiting list. Programs have also spread to places like Houston, Los Angeles, New York City, and North Carolina. It’s true that the number of students learning Chinese is tiny compared with how many study Spanish or French.
Advocates see knowledge of the Chinese language and culture as a help in a global economy where China is growing in importance. “This is an interesting way to begin to engage with the world’s next superpower,” says Michael Levine, director of education at the Asia Society, which has started five new public high schools that offer Chinese. “Globalization has already changed the arrangements in terms of how children today are going to need to think about their careers… The question is, when not whether, the schools are going to adjust.”
In Chicago, the trend extends beyond schools with high numbers of Asian students. “The fact that my students are 98% low income and 99% Latino(拉丁美洲人) and they are succeeding in this, tells me everyone should have a try at learning languages,” says Virginia Rivera, principal at McCormick. “We want to give our young people opportunities to advance… and Chinese is a great opportunity to survive in today’s economy,” says Richard M. Daley, Mayor of Chicago.
【小题1】The underlined word “Advocates” in the text probably means” .
A.Supporters | B.Objectors | C.Teachers | D.Learners |
A.Six. | B.Two. | C.Three. | D.Four. |
A.the competition between Latino and Asian students |
B.the global economy |
C.the interesting way to engage with China |
D.the Chinese learning |
A.Most students at McCormick can speak three languages. |
B.Chinese is gaining its popularity in all schools in Chicago. |
C.French has far more speakers than Chinese does in Chicago. |
D.Globalization in a way makes it necessary to learn Chinese. |
A.The Chinese learning in Chicago. |
B.The ways to learn Chinese. |
C.McCormick Primary School. |
D.Globalization and Chinese learning. |

For as long as humans have lived on the earth, they have made use of various forms of communication. Generally, this expression of thoughts and feelings has been in the form of oral speech. When there is a spoken language problem, communication can be carried out through sign language, in which gestures stand for letters, words, and ideas. Tourists and people unable to hear or speak have often had to turn to this form of expression. When gestures describe words or ideas, they can often be used internationally(各国之间地). When used for spelling words however, where each gesture stands for a single letter, people must share the same written language.
Body language sends ideas or thoughts by certain actions, either meaningfully or not. A wink(眨眼, 使眼色)can be a way of showing that the person is only joking. A nod means agreement, while shaking the head indicates disagreement.
Other forms of language can be found in Braille(a reading system of raised dots read with the fingertips used by the blind), signal flags, Morse code, and smoke signals. Road maps and picture signs also guide and warn people. While language is the most common form of communication, other systems and techniques also express human thoughts and feelings.
【小题1】 What does the author mainly want to say?
A.People can communicate in many different ways. |
B.Everybody uses only one form of communication. |
C.Language is invaluable to foreigners. |
D.Non-spoken communication is of little value. |
A.Fingers. | B.Eyes. | C.Head. | D.Feet. |
A.Spelling. | B.Ideas. |

An idea that started in Seattle's public library has spread throughout America and beyond. The concept is simple: help to build a sense of community in a city by getting everyone to read the same book at the same tome.
In addition to encouraging reading as a pursuit (追求) to be enjoyed by all, the program allows strangers to communicate by discussing the book on the bus, as well as promoting reading as an experience to be shared in families and schools. The idea came from Seattle librarian Nancy Pearl who launched (发起)the "If All of Seattle Read the Same Book " project in 1998. Her original program used author visits, study guides and book discussion groups to bring people together with a book, but the idea has since expanded to many other American cities, and even to Hong Kong.
In Chicago, the mayor(市长)appeared on television to announce the choice of To Kill a Mockingbird as the first book in the "One Book, One Chicago" program. As a result, reading clubs and neighbourhood groups sprang up around the city. Across the US, stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character.
The only problem arose in New York, where local readers could not decide on one book to represent the huge and diverse population. This may show that the idea works best in medium-sized cities or large towns, where a greater sense of unity(一致)can be achieved .Or it may show that New Yorkers rather missed the point ,putting all their energy
And passion into the choice of the book rather than discussion about a book itself.
Ultinatel was Nancy points out, the level of success is not measured by how many people read a book, but by how many people are enriched by the process. or have enjoyed speaking to someone with whom they would not otherwise have shared a word.
【小题1】 What is the purpose of the project launched by Nancy?
A.To invite authors to guide readers. |
B.To encourage people to read and share. |
C.To involve people in community service. |
D.To promote the friendship between cities. |
A.They had little interest in reading. |
B.They were too busy to read a book. |
C.They came from many different backgrounds |
D.They lacked support from the local government |
A.In large communities with little sense of unity |
B.In large cities where libraries are far from home |
C.In medium-sized cities with a diverse population |
D.In large towns where agreement can be quickly reached |
A.exchanged ideas with each other |
B.discussed the meaning of a word |
