Write a multi-choice question for the following article: Article: The human body has hundreds of muscles. The three types are skeletal muscles, smooth muscles and cardiac, or heart muscles. Each kind of muscle has a special job to do. The skeletal muscles are attached to the bones; they actually hold the skeleton together. Strong cords, called tendons , help connect these muscles to the bones. Skeletal muscles give us strength and allow us to move in many ways. If you look at skeletal muscles through a microscope, you will see that it has bands of fibers that look like stripes . These stripes are called striations. Skeletal muscles usually move because the brain has sent a conscious message to them telling them what to do. This is called voluntary movement. Another type of muscle is smooth muscle. Unlike skeletal muscle, smooth muscle does not have striations. This is found in organs such as the stomach, the bladder , the lungs and the eyes. Smooth muscles are smaller than the skeletal muscles and they move involuntarily. The brain tells these muscles what to do, but we aren't even aware of it. For example, we don't have to think about breathing or digesting food. The smooth muscles just do their jobs automatically. For this reason smooth muscles are sometimes called involuntary muscles. Like smooth muscle, cardiac muscle also works involuntarily. It is a very thick muscle that is found only in the walls of the heart. Its job is to pump blood out of the heart and into blood vessels called arteries . The arteries help carry the blood to all parts of the body. When the cardiac muscles relax, they let blood back into the heart. Cardiac muscles have striations, just like skeletal muscles do.
Ans: Question: Skeletal muscles and heart muscles are alike because _ .Options:A both can move voluntarilyB both are thick musclesC both are bigger than smooth musclesD both have stripes called striationsAnswer:D

Write a multi-choice question for the following article: Article: Robert Spring, a 19th century forger , was as good at his profession that he was able to make his living for 15 years by selling false signatures of famous Americans. Spring was born in England in 1813 and arrived in Philadelphia in 1858 to open a bookstore. At first he make some money by selling his small but genuine of early U.S. autographs . Discovering his ability at copying handwriting, he began imitating signatures of George Washington and Ban Franklin and writing them on the title pages of old books. To make less the chance of detection , he sent his forgeries to England and Canada for sale and circulation . Forgers have a hard time selling their products. A forger can't approach a respectable buyer but must deal with people who don't have much knowledge in the field. Forgers have many ways to make their work look real. For example, they buy old books to use the aged paper of the title page, and they can treat paper and ink with chemicals. In Spring's time, right after the Civil War, Britain was still fond of the Southern states, so Spring invented a respectable maiden lady known as Miss Fanny Jackson, the only daughter of General "Stonewall" Jackson. For several years Miss Fanny's economic problems forced her to sell a great number of letters and manuscripts belonging to her famous father. Spring had to work very hard to satisfy the demand. All this activity did not prevent Spring from dying in poverty, leaving sharp-eye experts the difficult task of separating this forgeries from the originals.
Ans: Question: Robert Spring spent 15 years _ .Options:A running a bookstore in PhiladelphiaB corresponding with Miss Fanny JacksonC as a forgerD as a respectable dealerAnswer:C

Write a multi-choice question for the following article: Article: Although English is not as 0old as Chinese it is spoken by many people around the world every day. English speakers are always creating new words, and we should be able to know where most words come from. Sometimes, however, no one may really know where a word comes from. Did you ever think about why hamburgers are called hamburgers, especially when they are not made with ham ? About a hundred years ago, some men went to America from Europe. They came from a big city in Germany called Hamburg. They did not speak good English. But they ate good food. When some Americans saw them eating round pieces of beef ,they asked the Germans what it was. The Germans did not understand the question and answered, "We came from Hamburg." One of these Americans owned a restaurant, and had an idea. He cooked some round pieces of beef like what the men from Hamburger ate. Then he put them between two pieces of bread and started selling them. Today "hamburgers" are sold in many countries around the world. Whether this story is true or not, it certainly is interesting. Knowing why any word has a certain meaning is interesting, too. The reason may be found in any large English dictionary.
Ans: Question: According to the story, the word "hamburgers" comes from _ .Options:A China because it has a long history.B England because Germans don't speak good English.C The round pieces of beef those people from Hamburg brought to America.D English speakers because they always create new words.Answer:C

Write a multi-choice question for the following article: Article: Ears are for hearing -- everyone knows that. But for a creature called the Cuvier's beaked whale, hearing starts in the throat, a new study found. The observation might help explain how all whales hear. The work might also help scientists understand how animals are affected by underwater sonar . This sonar, used by some ships, sends out sound waves to locate underwater objects. The Cuvier's beaked whale is a so-called toothed whale. Toothed whales dive deep into the ocean in search of food. As the whales hunt, they produce sounds that reach objects and then return to the whales. This allows the animals to "see" the shape, size, and location of objects, even when they're 1,000 meters under the sea, where it is totally dark. To better understand how the whale hears, researchers from San Diego State University in California took X-rays of two Cuvier's beaked whales. The whales had died and washed up on the beach. Ted Cranford and his colleagues used the images to make a computer model of a Cuvier's beaked whale's head. Then, they modeled the process of sound traveling through the head. The researchers knew that some sounds get to the ears of a toothed whale through a structure called "the window for sound". Found on the lower jaw, this structure is very thin on the outside and has a large pad of fat on the inside. When the researchers used their computer model to work out how sound waves travel in the whale's head, they were surprised to find that sounds coming from right in front of the whale actually travel under the animal's jaw. From there, sound waves move through the throat, into a hole in the back of the jaw, and finally to the pad of fat near the animal's ears. Cranford guesses that other types of whales may hear through their throats. Further testing is needed to be sure. Eventually, the insight into how whales hear might explain whether sonar testing by military ships is causing the animals to wind up on beaches.
Ans: Question: Toothed whales look for food under the sea by _ .Options:A watching the shape and size of their objectsB diving deep into the seaC sending and receiving soundsD making lots of noisesAnswer:C
