ple — their clothes, ideas, or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree(可可树)by South American. Indians. The Spanish introduced it to the rest of the world during the 1500’s. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Eu??rope, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish peo??ple starved when the crop failed during the "Potato Famine (饥荒)" of 1845—1846, and thousands more were forced to leave their homeland and move to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world’s largest grower of coffee, and coffee is an important crop in Colombia and other South American countries. But it is native to Ethiopia, a country in Africa. It was first made into a drink by Arabs during the 1400’s.
according to an. Arabic legend, coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee, bush. He tried one and experienced the " wide-awake" feeling that one third of the world’s population now starts the day with.according to the passage, which of the following has changed the most in the last 500 years?

The Pacific island nation of Nauru used to be a beautiful place. Now it is an ecological disaster area. Nauru's heartbreaking story could have one good consequence—other countries might learn from its mistakes.
For thousands of years, Polynesian people lived on the remote island of Nauru, far from western civilization. The first European to arrive was John Fearn in 1798. He was the British captain of the Hunter, a whaling ship. He called the island Pleasant Island.
However, because it was very remote, Nauru had little communication with Europeans at first. Then whaling ships and other traders began to visit, bringing guns and alcohol. These elements destroyed the social balance of the twelve family groups on the island. A tenyear civil war started, which reduced the population from 1,400 to 900.
Nauru's real troubles began in 1899 when a British mining company discovered phosphate(磷酸盐) on the island. In fact, it found that the island of Nauru was nearly all phosphate, which is a very important fertilizer for farming. The company began mining the phosphate.
A phosphate mine is not a hole in the ground; it is a stripmine. When a company stripmines, it removes the top layer of soil. Then it takes away the material it wants. Stripmining totally destroys the land. Gradually, the lovely island of Nauru started to look like the moon.
In 1968, Nauru became one of the richest countries in the world. Every year the government received millions and millions of dollars for its phosphate.
Unfortunately, the leaders invested the money unwisely and lost millions of dollars. In addition, they used millions more dollars for personal expenses. Soon people realized that they had a terrible problem—their phosphate was running out. Ninety percent of their island was destroyed and they had nothing. By 2000, Nauru was almost financially ruined. Experts say that it would take approximately $433,600,000 and more than 20 years to repair the island. This will probably never happen.What might be the author's purpose in writing the text?

Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers.
Their study found that theobromine, found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present.
The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. “While coughing is not necessarily harmful(有害的) it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem,” said Professor Peter Barnes.
Ten healthy volunteers(志愿者) were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicine are stopping coughs.
The team found that, when the volunteers were given theobromine, the capsaicin need to produce a cough was around a third higher than in the placebo group. When they were given codeine they need only slightly higher levers of capsaicin to cause a cough compared with the placebo.
The researchers said that theobromine worked by keeping down a verve activity(神经活动), which cause coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness.According to Professor Barnes, theobromine ______.
| A．cannot be as effective as codeine |
| B．can be harmful to people’s health |
| C．cannot be separated from chocolate |
| D．can be a more effective cure for coughs |
What was used in the experiment to cause coughing?
| A．Theobromine. | B．Codeine. | C．Capsaicin. | D．Placebo. |
We learn from the text that volunteers in the experiment _____.
| A．were patients with bad coughs |
| B．were divided into the three groups |
| C．received standard treatments |
| D．suffered little side effects |
Which of the following would be the best title for the text?
| A．Codeine: A New Medicine | B．Chocolate May Cure Coughs |
| C．Cough Treatment: A Hard Case | D．Theobromine Can Cause Coughs |
Make Up Your Mind to Succeed
Kindhearted parents have unknowingly left their children defenseless against failure. The generation born between 1980 and 2001 grew up playing sports where scores and performance were played down because “everyone's a winner.” And their report cards sounded more positive (正面的) than ever before. As a result, Stanford University professor Carol Dweck, PhD, calls them “the overpraised generation.”
Dweck has been studying how people deal with failure for 40 years. Her research has led her to find out two clearly different mindsets that have a great effect on how we react to it. Here's how they work：
A fixed mindset is grounded in the belief that talent (才能) is genetic—you're a born artist, point guard, or numbers person. The fixed mindset believes it's sure to succeed without much effort and regards failure as personal shame. When things get difficult, it's quick to blame, lie, and even stay away from future difficulties.
On the other hand, a growth mindset believes that no talent is entirely heavensent and that effort and learning make everything possible. Because the ego(自尊) isn't on the line as much, the growth mindset sees failure as a chance rather than shame. When faced with a difficulty, it's quick to rethink, change and try again. In fact, it enjoys this experience.
We are all born with growth mindsets. (Otherwise, we wouldn't be able to live in the world.) But parents, teachers, and instructors often push us into fixed mindsets by encouraging certain actions and misdirecting praise. Dweck's book, Mindset: The New Psychology of Success, and online instructional program explain this in depth. But she says there are many little things you can start doing today to make sure that your children, grandchildren and even you are never defeated by failure.What does the author think about the present generation?
| A．They don't do well at school. |
| B．They are often misunderstood. |
| C．They are eager to win in sports. |
| D．They are given too much praise. |
A fixed mindset person is probably one who ________.
| A．doesn't want to work hard |
| B．cares a lot about personal safety |
| C．cannot share his ideas with others |
| D．can succeed with the help of teachers |
What does the growth mindset believe?
| A．Admitting failure is shameful. |
| B．Talent comes with one's birth. |
| C．Scores should be highly valued. |
| D．Getting over difficulties is enjoyable. |
What should parents do for their children based on Dweck's study?
| A．Encourage them to learn from failures. |
| B．Prevent them from making mistakes. |
| C．Guide them in doing little things. |
| D．Help them grow with praise. |

Phil White has just returned from an 18,000mile, aroundtheworld bicycle trip. White had two reasons for making this epic journey. First of all, he wanted to use the trip to raise money for charity, which he did. He raised￡70,000 for the British charity, Oxfam. White's second reason for making the trip was to break the world record and become the fastest person to cycle around the world. He is still waiting to find out if he has broken the record or not.
White set off from Trafalgar Square, in London, on 19th June 2004 and was back 299 days later. He spent more than 1,300 hours in the saddle (车座) and destroyed four sets of tyres and three bike chains. He had the adventure of his life crossing Europe, the Middle East, India, Asia, Australia, New Zealand and the Americas. Amazingly, he did all of this with absolutely no support team. No jeep carrying food, water and medicine. No doctor. Nothing! Just a bike and a very, very long road.
The journey was lonely and desperate at times. He also had to fight his way across deserts, through jungles and over mountains. He cycled through heavy rains and temperatures of up to 45 degrees, all to help people in need. There were other dangers along the road. In Iran, he was chased by armed robbers and was lucky to escape with his life and the little money he had. The worst thing that happened to him was having to cycle into a headwind on a road that crosses the south of Australia. For 1,000 kilometres he battled against the wind that was constantly pushing him. This part of the trip was slow, hard work and depressing, but he made it in the end. Now Mr. White is back and intends to write a book about his adventures.When Phil White returned from his trip, he ________.
