Four decades ago a group of college students visited the mountains of Borneo to examine moth populations. Now a team of British scientists, including a member of the original trip, has returned to the same sites to repeat the survey. They have found that, due to rising temperatures, the insects now live 68 meters higher. Global warming is forcing tropical species uphill to escape the rising temperatures at a rate of nearly 2 meters a year, the new study from Borneo suggests. Since this was the only chance to repeat the original survey, the scientist did everything they could to do it exactly the same way, going at the same time of year, in July and August, using photographs to find the exact original sites of the moth traps. "While this is the first study of insects, a few other studies of tropical species are starting to appear," said Thomas. "If you look across all those studies, you'll find the same results, and it's extremely difficult to think of any other explanation for them." While some species might survive by finding places on the mountains with temperatures similar to those of their original habitats, others may run out of habitat on the rocky peaks, warns the study. In a paper in the journal Naturein 2004, Thomas and 13 other experts analyzed the habitats of 1,100 species on five continents, and estimated that on average one quarter were at risk of extinction. Last year a paper published in the Public Library of Science in the US warned that the risk of extinction in the tropics was becoming more and more serious. The authors, Jana and Steven Vamosi, estimated that 20-45% of tropical species were at risk of extinction. We can learn from the passage that _ . A) this survey of moths has been carried out many times B) some scientists have put forward other explanations for the results C) scientists tried to repeat the original survey D) 20-45% of tropical species were estimated to be at risk of extinction in 2004

One man tells of driving on a long and lonely road, the last 65 miles of it unpaved, in order to watch Indian dances in the state of Arizona.After the dances, he returned to his car only to find that it had a flat tire.He put on the spare and drove to the only service station in that town. "Do you fix flats?" he inquired of the attendant. "Yes," came the answer. "How much do you charge?" he asked. With a twinkle in his eye, the man replied, "What difference does it make?" This is what has been called a "Hobson's choice".A Hobson's choice is a situation that forces a person to accept whatever is offered or go without. According to Barbara Berliner, the phrase was inspired by sixteenth-century entrepreneur Thomas Hobson.There was no choice by the customer -- it was strictly Hobson's choice. But often we really have a choice, and the choice does make a difference.We may not always believe it.We may feel as if we have no choice, but almost always there is a choice in the matter.And when we realize that we do most things by choice, then we are taking control of our own lives. Someone challenged me to try an experiment that completely changed my perspective(,)."For the next seven days," he said, "remove the words 'I have to' from your vocabulary and say 'I choose to'.Don't say, 'I have to work late tonight'.Instead, say, 'I choose to work late'.When you choose to do it, you take control of your life.Instead of saying 'I have to stay home', try 'I choose to stay home'.The way you spend your time is your choice.You are responsible.You have control." In just seven days I was no longer saying "I have to" and I felt better about my decisions.I learned that there is very little in my life I actually have to do.You and I decide to do certain things because we believe that it will be for the best.When we remove "I have to" from our vocabularies, we take control. Try it for a week and you see what happens.I think you'll see it's a change for the better. What's the best title of this passage? A) I Have To B) I Choose To C) Hobson's Story D) Fix a Flat Tire
