Etymology, the study of words and word roots, may sound like the kind of thing done by boring librarians in small, dusty rooms.Yet etymologists actually have a uniquely interesting job.They are in many ways just like archaeologists   digging up the physical history of people and events.The special aspect of etymology is that it digs up history, so to speak, through the words and phrases that are left behind. The English language, in particular, is a great field to explore history through words. As a language, English has an extraordinary number of words.This is partly due to its ability to adapt foreign words so readily.For example, "English" words such as kindergarten (from German), croissant (from French), and cheetah (from Hindi) have become part of the language with little or no change from their original sounds and spellings. So English-language etymologists have a vast world of words to explore. Another enjoyable thing about etymology for most word experts is solving word mysteries .No, etymologists do not go around solving murders, like the great detective Sherlock Holmes.What these word experts solve are mysterious origins of some of our most common words One of the biggest questions English language experts have _ is how English came to have the phrase OK.Though it is one of the most commonly used expressions, its exact beginning is a puzzle even to this day.Even its spelling is not entirely consistent-unless you spell it Okay, it is hard even to call it a word. Etymologists have been able to narrow OK's origin down to a likely, although not certain, source .It became widely used around the time of Martin Van Buren's run for president in 1840. His nickname was Old Kinderhook. What troubles word experts about this explanation is that the phrase appeared in some newspapers before Van Buren became well known.It is likely that Van Buren could be called its primary source Etymologists will doubtlessly keep searching for the initial source.However, it is clear that OK's popularity and reputation have... We can learn from the passage that etymologists  _  . A) discover the possible origin of words B) help detectives to solve mysterious murders C) write interesting stories for some newspapers D) explore the English language as well as the recent events

Are you carrying too much on your back to school? I'm sure lots of your age will say "Yes". Not only the students in China have this problem, but children in the United States also have heavy school bags.  Doctors are starting to worry about that younger and younger students are having problems as a result of school bags being too heavy for them. "It's hard for me to go upstairs with my bag because it's so heavy," said Rich Hammond, an 11-year-old student in the US. Rich is among students who have common school bags with two straps to carry them, but many other choose rolling   bags. But even with rolling bags, getting up stairs and houses is still a problem for children. Many of them have hurt backs and necks because of the heavy school bags. But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight. Scott Bautch, a black doctor, said children under Grade 4 should stay with 10%. But it is also important that older children don't stay with over 15%, because their bodies are still growing. "Children are losing their balance and falling down with their school bags," he said. Parents and teachers are starting to tell children to only take home library books that they will be reading at night. Some teachers are using pieces of paper or thin workbooks for students to take home.  One of the best answers is, as some children said, to have no homework at all. From the passage we can learn that  _  . A) only children in China carry too heavy school bags B) children in other countries don't carry too heavy school bags C) both children in China and the US carry too heavy school bags D) only children in the US carry too heavy school bags
