Vinegar makes salad,fries and dumplings taste better, and you can even use it to clean your windows. And now, according to scientists, it may even the planet's population survive climate change.
Researchers from the RIKEN Center for Sustainable Resource Science (CSRS) in Japan found that growing plants in vinegar makes them more resistant to droughts. This could mean that in the future, worries about climate change affecting the world's supply of food will be much lower. The discovery was made after the researchers studied the Arabidopsis, a plant known for its ability to survive in dry weather. It was found that when the plant was placed in drought﹣like conditions, it produced a chemical called acetate(醋酸盐)﹣the main component of vinegar.
After discovering this, the scientists experimented further by adding acetate to the soil of other plants, before they stopped giving them water completely. After leaving the plants for 14days, they found that the ones treated with acetate had survived, while the untreated plants had dried up and died.
It's hoped that this simple method of survival could soon be used to help farmers in dry countries keep their crops alive. "In the experiment, we targeted the staple foods of the world﹣rice, wheat and maize﹣and the basic plant of breeding species, rapeseed(油菜籽)," Jong Myong Kim, co﹣author of the study, told Popular Science magazine.
Kim also told the magazine he's already been in touch with people all over the world who are interested in trying this simple and cost﹣effective method out for themselves from flower growing companies to amateur gardeners. Although at this point keeping thirsty plants alive isn't as easy as just pouring vinegar over them, Kim said he and his team are working on making the process as simple as possible. "Now we are trying to cooperate with some farmers, and also some companies, to make a method to apply this system, "he said. And for those of us who always forget to ask our neighbors to water our plants when we goaway, hopefully this means the end of returning home from a trip to find our favorite flowers have died.

There is no better way to enjoy Scottish traditions than going fishing and tasting a little whisky(威士忌) at a quiet place like the Inverlochy Castle. When Queen Victoria visited there in 1873 she wrote in her diary, “I never saw a lovelier spot,” And she didn't even go fishing.
Scotland is not easily defined. In certain moments, this quiet land of lakes and grass mountains changes before your very eyes. When evening gently sweeps the hillside into orange, the rivers, teeming with fish, can turn into streams of gold. As you settle down with just a people and a basket on the bank of River Orchy, near the Inverlochy Castle, any frustration will float away as gently as the circling water. It's just you and purple, pink, white flowers, a perfect harmony. If you are a new comer to fishing, learning the basics from a fishing guide may leave you with a lifetime's fun. For many, fishing is more than a sport; it is an art.
Scotland offers interesting place where you can rest after a long day's fishing. Set against a wild mountain and hidden behind woodland, the beautiful Inverlochy Castle Hotel below the Nevis is a perfect place to see the beauty of Scotland's mountains. Ben Nevis is the highest of mountains, and reaching its 1342-metre top is a challenge. But it's not just what goes up that matters; what comes down is unique. More than 900 metres high, on the mountain's north face, lies an all-important source of pure water. Its name comes form the Gaelic language "usqueb" or "water of life"; and it is the single most important ingredient(原料) in Scotland's best known whisky.
1.The story of Queen Victoria is to show that ________.
A. the queen is rich in tour experience
B. the Castle is a good place to go in Scotland
C. tasting whisky is better than going fishing
D. 1873 is a special year for the queen
2.How is Paragraph 2 mainly developed?
A. By giving descriptions. B. By following time order.
C. By analyzing causes. D. By making comparisons.
3.What is Ben Nevis special for?
A. The Inverlochy Castle Hotel.
B. The beauty of its surroundings.
C. The water from the mountain.
D. The challenge up to its top.
4.What is the main purpose of the passage?
A. To introduce Scottish traditions to tourists.
B. To show the attractions of Scotland to readers.

It wasn't until the 1970's that tofu started to become better known, during a wave of interest in vegetarianism(素食主义),natural food, and less wasteful food sources. 5. And the restaurant. chain Chipotle successfully added tofu to its menu a few years ago.
