Fireworks are exciting, but also hard to control. The Chinese artist Cai Guoqiang, though, has developed a way to harness the visual and physical power of fireworks to make art He recently used them to create a burning sculpture that stretched high into the sky. Guoqiang fittingly named the work Sky Ladder.

Guoqiang built Sky Ladder by making a frame out of metal. He coated the frame with gunpowder, the main chemical material in fireworks.

The artist tried one end of the frame to the ground and attached a large weather balloon to the other end. The balloon was filled with helium 一 a gas that is lighter than air. When released, the balloon floated upward, pulling the top of the ladder 500 meters into the sky. That's higher than the top of the Empire State Building.

Guoqiang set fire to the bottom of the ladder, and the crackling（啪啪作响） flames raced skyward up the frame. The sculpture burned for two-and-a-half minutes before its flames began to die out from the bottom up.

Dealing with explosive（炸药） is challenging, and conditions had to be perfect for Guoqiang to achieve his desired effect. He first attempted Sky Ladder in 1994，but bad weather prevented him from successfully completing the work. Guoqiang put Sky Ladder aside so that he could work on other projects, perhaps most famously the fireworks display that opened the 2008 Beijing Olympic Games.

Finally, after two more failed attempts, Guoqiang successfully sent his flaming ladder skyward last year. He presented Sky Ladder in his hometown, a quiet fishing village near Huiyu Island, Quanzhou. He offered the work as a gift to his 100-year-old grandmother, other family members, his friends and his town.

"Behind Sky Ladder lies a clear childhood dream of mine, "Guoqiang explains. "Despite all life's twists and turns, I have always been determined to realize it. The ladder rose toward the morning sun, carrying hope. For me, this not only means a return, but also the start of a new journey. "

Greenhouse gas emissions would rise if all farms in England and Wales went organic. Though the emissions of each farm would go down, much more food would have to be imported, as the amount they would produce would decrease greatly.

"The key message from my perspective is that you can't really have your cake and eat it, " says Laurence Smith, now at the Royal Agricultural University in the UK, who was part of the team that ran the numbers. Smith is a supporter of organic farming and says "there are a lot of of the organic approach"，but his analysis shows that organic farming has downsides too.

Farming and changes in land use, such as cutting down forests, are responsible for a third of all greenhouse gas emissions. That means reducing farming emissions and the land needed for farming is required to limit further global warming.

Smith and his colleagues found that emissions per unit of food are, on average, 20 per cent lower for organic crops and 4 per cent lower for organic animal products. However, organic harvests per hectare （公顷） are also lower on average. For wheat and barley, for instance, harvests are just half of those of conventional farms. This means 1.5 times as much land would be needed to grow the same amount of these foods.

The estimated increase in emissions varies greatly, depending on where the extra farmland comes from. If only half comes from turning grassland into farms, the increase could be as low as 20 per cent. If grassland that would otherwise have been reforested is turned into farmland, emissions could nearly double.

This doesn't necessarily mean people should stop eating organic produce, says Smith. People might choose organic food for other reasons, such as to reduce their pesticide exposure （though contrary to popular belief, organic farmers do use pesticides） or for the sake of wildlife.

Going 100 per cent organic could also harm global biodiversity. The extra land used for farming would mean the land available for wildlife would be smaller and more fragmented （碎片化的）.

Smith says the best option may be to use some organic and conventional farming methods at the same time.

1. （1） Why may greenhouse gas emissions increase if a country goes organic?

   A . Organic farms take longer to build. B . The agricultural output will increase greatly. C . The emissions of each farm unit will increase. D . Greater demand for imported food will be created.
3. （2） What does the underlined word "merits" in Paragraph 2 probably mean?

   A . Changes. B . Challenges. C . Advantages. D . Differences.
5. （3） What did Smith and his colleagues find?

   A . Organic harvests per unit are greater than traditional harvests. B . Organic farming needs more farmland to feed a country. C . Global warming could be brought under control. D . Land was not used in a responsible way.
7. （4） What is Smith's proposal?

   A . Stopping using pesticides. B . Eating less organic produce. C . Going back to traditional farming. D . Adopting mixed farming methods.

Pieter Bruegel's iconic 1565 painting The Harvesters hangs at the Metropolitan Museum of Art. The work showed people harvesting wheat nearly as tall as they were. "nowadays, however, if you walk through a wheat field, you basically see that wheat is about knee-height. The reduced height is essentially a consequence of breeding （培育）along with genes for increasing production to feed a growing population, " biologist De Smet explained.

De Smet says wheat is just one example of how historical artwork can allow us to track the transformation of food crops over time. He teamed up with art historian Vergauwen, a friend since childhood, to document such artwork around the world. They have been mainly looking at things where they can spot changes in shape, color and size.

Their interest in plants in artwork began with a visit to the Hermitage Museum, where they noticed an odd-looking watermelon in an early-17th-century painting. It appeared to be pale and white on the inside. Biologist De Smet assumed the painter had done a poor job. But art historian Vergauwen had a different idea. "No, this is one of the best painters ever from that era. So if he painted it like that, that's the way it must have looked like, " he explained.

Other paintings revealed that both red and white watermelons were grown during the 17th century. "With all the genetic knowledge we now have, we can look in more detail how something comes about, "De Smet said. "For example, until the 18th century, European strawberries appeared tiny in paintings-they then grew in size as they were crossbred with North American varieties. "

Ultimately, the team hopes to create an online research database of historical plant artwork. They seek the contributions of art enthusiasts around the world via the social media. "However, " Vergauwen reminds, "if you're going to use, for example, Picasso to try and understand how a pear looked in the early 20th century, you might be misled. "

1. （1） What can we learn about the painting The Harvesters?

   A . It shows how people successfully grew wheat. B . It proves that wheat was much shorter in the past. C . It explains the consequence of different breeding methods. D . It gives clues about how wheat in the 16th century looked like.
3. （2） What inspired the research team to start their study?

   A . Their preference for food crops. B . Their friendship since childhood. C . Their divided views on an old painting. D . Their shared interest in Hermitage Museum.
5. （3） What is the message from Vergauwen in the last paragraph?

   A . Art enthusiasts are not careful enough. B . Abstract paintings often mislead people. C . The source paintings need to be realistic. D . Picasso's paintings are hard to understand.
7. （4） What is the purpose of the text?

   A . To comment on historical plant paintings. B . To tell interesting stories behind plant artwork. C . To inform readers of a scientific breakthrough. D . To introduce a study on food crop transformation.

When he was fourteen, his ambition was to run a pub, just like his dad. With a chain of restaurants, a number of popular television series and best-selling cookery books, Jamie Oliver is a well-known name in every UK household. I'm a huge "Jamie fan" . I admire his passion for improving the food we eat and helping people change their lives.

He took fifteen unemployed young people, with no previous experience of cooking, and trained them to be top-class chefs（厨师）in his restaurant, also called Fifteen. I remember one trainee, Lloyd Hayes. He left school with no qualifications and started getting into crime. I think it's this kind of success story that makes Jamie and his projects so special.

Another special project is Jamie's Ministry of Food which he started in 2008. There are two aims：firstly, to teach people how to cook healthy, affordable food instead of eating fast food；secondly, to set up the Pass It On scheme：encouraging each person to pass on a recipe they learned to four other people. Thousands of people have changed their cooking habits as a result - and I'm one of them. I've decided I'm not going to eat fast food anymore.

It's not only adults, but children, too. Jamie's School Dinners, one of Jamie's best-known projects, tried to improve food in schools and encourage children to eat well. It was difficult to convince some of the children, but in the end, many schools improved their menus.

So, what's Jamie going to do next?Well, whatever it is, one thing is for sure, I'm not going to miss it!

A. I heard recently that she is going to teach people to cook.

B. And my children are going to eat their vegetables now.

C. Jamie's first project, Fifteen, in 2002，aimed to help young people.

D. I'm going to cook for my friends and take time to eat good food.

E. Those four people then teach four more people, and so on.

F. But the project worked and Lloyd got a job as a chef in a top restaurant.

G. But in the last twenty years, chef Jamie Oliver has achieved far more.
