People can dine out on the rudeness they have experienced," says Professor Tony Seaton of Luton University's International Tourism Research Center. Poor public transport: Trains and buses are promised to defeat the keenest tourists, although the over-crowded London tube is inexplicably popular. Lack of language: Speaking slowly and clearly may not get many foreign visitors very far, even in the tourist traps. Rain: Still in the number one complaint.

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Wind , water, fire and ice-these powerful natural forces have shaped the land of America in the past. They are still changing it today. The Colorado River slowly cut down through stone to make the Grand Canyon . Long ago, ice sheets cut Yosemite Valley and the Great Lakes, and glaciers are still on the move in Alaska. Wind and rain storm hit the land from time to time. Fires sometimes burn down forests and destroy the homes of wild animals. This happened in Yellowstone Park in 1988. Dead volcanic mountains such as Haleakala on Maui and Carter Lakein Oregon are beautiful to look at. But there are several active volcanoes in the US, especially along the Pacific Coast. There are also many earthquakes in this area. Scientists can do nothing to control earthquakes or volcanoes. This was shown clearly on May 18, 1980. At 8:32 that morning, Mount St Helens in Washington state broke out. The top of the mountain was blown off. Over 60 people -campers, scientists, journalists, forest workers--were killed. Hundreds of square miles of forests were knocked down. In towns over 100 miles away, day suddenly became night. An ash cloud hid the sun for many hours. Towns and fields in Washington, Oregon, and Idaho were covered with dirty gray ash. Scientists knew that Mt St Helens might erupt soon. But no one could say when. And no one expected the terrible strength of the eruption. Many people were surprised and unready. Harry R. Truman, 84, owned a small hotel in Mt St Helens. Scientists had asked people to move away because the volcano was becoming dangerous. But Harry Truman would not leave his home. Now _ is covered with many feet of dirty ash. A small cross stands above the place where Harry probably died. Perhaps it is better that he did not see the destruction of Mt St Helens, the once beautiful lake, and the forests. But slowly, life is returning to the dead area around the mountain. Grass and small plants are beginning to grow again. Deer and birds have been seen. The land will never be the same as it once was.... Options: A Washington and Oregon are neighboring states B Colorado River runs through Yosemite Valley C The eruption of Mt St Helens also caused trouble with the Yellowstone Park D Scientists never knew Mt St Helens was active Answer: A Washington and Oregon are neighboring states Question:

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: If you look at the night sky, you'll often see stars moving very quickly. In fact, they move much more quickly than they should according to their size and the laws of physics. Scientists do not completely understand why the speed of these stars is so high. But many believe the reason is that much of the universe is made of something called "dark matter". Groups of stars called galaxies, such as the Milky Way, might even be made up of 90 percent dark matter. How much something weighs depends on where it is. The same object weighs only half as much on Mars as it does on Earth and almost three times as much on Jupiter. So scientists prefer to talk about the mass of something rather than how much it weighs, because mass does not change. They can work out the mass of galaxies by measuring the distance between them and the speed they move at. Recently, Jorge Penarrubia, a senior academic at Edinburgh University, UK, and his team discovered something interesting: The mass of the Milky Way is only half as much as the mass of another nearby galaxy, Andromeda. This seems strange, and dark matter may explain why. Finding out more about dark matter could help us understand how the universe began, but this is not easy. Lots of scientists with different types of expert knowledge are working on the problem. We can't see dark matter, it's very difficult to measure and we can't find out its mass. Unlike stars, dark matter doesn't produce or reflect light. But we can make a good guess that it is there because of the way things move and the way light bends. Experts now think dark matter may be very different from the matter that we find on Earth. There may also be five times as much dark matter in the universe as ordinary matter. Options: A it travels at a very fast speed B we can't see where it is or measure its mass C it's hard to measure the light it produces and reflects D it is much bigger than ordinary matter in size Answer: B we can't see where it is or measure its mass Question:

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Students who say they never or hardly ever used dictionaries often speak English well but usually write poorly, because they make many mistakes. The students who use dictionaries most do not learn especially well either. The ones who look up every word do not read fast. Therefore they do not have time to read much .Those who use small two-language dictionaries have the worst problems. Their dictionaries often give one or two words as a translation of English. But one English word has many English translations in Chinese. The most successful students are those who use large college edition dictionaries with about 100,000 words but do not use them often, When they are reading these students first try to get the general idea and understand the new words from the context .Then they read and use the dictionary to look up only key words that they still do not understand. They use dictionaries more for writing. Also if they think a noun might have an unusual plural form or a verb might have an unusual past form, they check these in a dictionary. Options: A Those students should use small two-language dictionaries. B What were the effects of small two-language dictionaries? C Why students should use large college edition dictionaries? D What kind of dictionary students should choose and how to use it? Answer: D What kind of dictionary students should choose and how to use it? Question:
