Man&39;s first real invention, and one of the most important inventions in history, was the wheel. All transportation and every machine in the world depend on it. The wheel is the simplest yet perhaps the most remarkable of all inventions, because there are no wheels in nature-no living thing was ever created with wheels. How, then, did man come to invent the wheel？ Perhaps some early hunters found that they could roll the carcass of a heavy animal through the forest on logs more easily than they could carry it. However, the logs themselves weighed a lot.

• It began with three friends searching for an easier way to share videos. One - Jawed Karim - uploaded the site&39;s first clip - a movie of himself dressed in an anorak at San Diego Zoo.

  By the end of its first year YouTube was broadcasting 25 million videos a day and it was soon bought by the internet giant Google. In 2010 24 hours of video are now uploaded every minute. The site&39;s also become an important political tool - almost a million people watched a wounded girl dying during protests in Iran in July 2009. President Barack Obama successfully used the site during his election campaign. Thousands of teenagers around the world have also used the site to upload embarrassing videos of friends and its creators have been forced to deny claims that it&39;s encouraged bullying.

• There has been, in history, a man who was swallowed by a whale and lived to tell the tale. The man&39;s name is James Bartley. The records to prove his unusual experience are in the British Admiralty.

  Bartley was making his first trip on the whaling ship Star of the East. Suddenly the lookout sighted a huge sperm whale. The whalers knew it was a huge whale by the size of the spray it blew into the air. They lowered their small boats. James Bartley was in the first longboat. The men rowed until they were close to the whale. A harpoon was thrown and it found its mark. It sank into the whale&39;s flesh. The maddened beast crashed into the boat, snapping its tail at the men and the wreckage of their boats. When the survivors were picked up, James Bartley was missing. Shortly before sunset, the whale was finally captured. The sailors tied the whale&39;s dead body to the side of the ship. Because of the hot weather it was important that they cut up the whale right away. Otherwise, the meat would begin to rot and oil would begin to spoil. When they got to the stomach, they felt something moving about wildly. They thought it would be a big fish still alive inside. But when they opened the stomach they found James Bartley. After this trip, Bartley settled in England, and never returned to sea. 1、This passage is mainly about__________. A.how to hunt whales for their oil and meat B.The hard and dangerous lives that whalers had to live C.The duties of each man on a whaling ship D.a man who was swallowed by a whale and lived James Barfley probably never went to sea again because__________.A.he wanted different kinds of adventures B.of fright and shock C.he was crippled by the whale D.he often got seasick The sailors knew that something was in the whale's stomach because__________.A.they could feel it moving about wildly B.The whale seemed very heavy C.The whale was swelling at one spot D.The captain heard Bartley yelling for help The author, in telling James Bartley's story, informs us by__________.A.narrating the plain facts B.referring to whaling in general C.comparing whaling to other fishing D.dramatically telling what happened 请帮忙给出每个问题的正确答案和分析，谢谢！

• How man first learnt to invent words is unknown; in other words, the origin of language is a mystery. All we really know is that man, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to stand for those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words.

  The power of words, then lies in their association with the things they bring up before our minds. Words became filled with meanings for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increase. Great writers are those who not only have great thoughts but also express these thoughts in words that appeal powerfully to our minds and emotions. We should therefore learn to choose our words carefully and use them exactly, or they will make our speech silly and impolite. The origin of language is ______. A．clearly explained in this passage B．a matter that can not be or has not been explained or understood C．a question that was difficult to answer D．a problem already solved

• To get a sense of how women have progressed in science, take a quick tour of the physics department at the University of California, Berkeley. This is a storied place, the 36 of some of the most important discoveries in modern science—starting with Ernest Lawrence’s invention of the cyclotron (回旋加速器) in 1931. A generation ago, female faces were 37 and, even today, visitors walking through the first floor of LeConte Hall will see a full corridor of exhibits 38 the many distinguished physicists who made history here, 39 all of them white males.

  But climb up to the third floor and you’ll see a 40 display. There, among the photos of current faculty members and students, are portraits of the 41 head of the department, Marjorie Shapiro, and four other women whose research 42 everything from the mechanics of the universe to the smallest particles of matter. A sixth woman was hired just two weeks ago. Although they’re still only about 10 percent of the physics faculty, women are clearly a presence here. And the real 43 may be in the smaller photos to the right: graduate and undergraduate students, about 20 percent of them female. Every year Berkeley sends its fresh female physics PhDs to the country’s top universities. That makes Shapiro optimistic, but also 44 . “I believe things are getting better,” she says, “but they’re not getting better as 45 as I would like.” A) circumstance B) confidence C) covers D) current E) deals F) different G) exposing H) fast I) honoring J) hope K) presently L) rare M) realistic N) site O) virtually
