Every year gray whales migrate from the Bering Sea in Alaska to the Baja Peninsula in Mexico.Eleven gray whales have died in the San Francisco Bay in the last three weeks．No one knows why the whales are dying.Last year 270 whales died along the whales'migration route．Many people think starvation is the cause．This year the dead whales seem to have more blubber(fat)on them.Twenty years ago,the gray whale was listed as an endangered species.Some scientists think that the larger number of whales makes it hard to find enough food．More whales create more pressure on the food supply,a supply that some scientists say may have dwindled as a result of the warm waters of El Nino.Most of the whales have been dead for many days before they are found and studied．This makes it hard to find the reason for death.65 whales have been seen in the San Francisco Bay Area this year compared to 17 last year．The whales could be dying from many diseases,but it may be over-population．One reason it is difficult to know why the whales are dying is that__.A.the whales travel such a long distanceB.there are more whales than there used to beC.the whale bodies are too old to study by the time they are foundD.the whales are endangered
The number of home users and small businesses that want to use the Internet is ever increasing. The shortage of addresses is becoming a serious problem. A quick solution to this problem is called network address translation(NAT).NAT enables a user to have a large set of addresses（ ）and one address, or a smallset of addresses,externally. The traffic inside can use the large set; the traffic（ ）, the small set. To separate the addresses used inside the home or business and the ones used for the Internet, the Internet authorities have reserved three sets of addresses as （ ） addresses. Any organization can use an address out of this set withoutpermission from the Internet authorities. Everyone knows that these reserved addresses are for private networks.They are （ ） inside the organization, but they are not unique globally. No router will （请作答此空） a packet that has one of these addresses as the destination address.The site must have only one single connection to the global Internet through a router that runs the NAT software.A.rejectB.receiveC.denyD.forward
共用题干What Makes a Soccer Player Great?Soccer is played by millions of people all over the world,but there have only been few play-ers who were truly great.How did these players get that way—was it through training and prac- tice,or are great players“born,not made”?First,these players came from places that have had famous stars in the past-players that a young boy can look up to and try to imitate.In the history of soccer,only six countries have ever won the World Cup-three from South America and three from western Europe .There has never been a great national team-or a really great player-from North America or from Asia.Second,these players have all had years of practice in the game.

For example,Liverpool,which produced the Beetles,had one of the bestEnglish soccer teams in recent years.Pele practiced in the street with a“ball”made of rags.And George Best learned the tricks that made him famous by bouncing the ball off a wall in the slums of Belfast.All great players have a lot in common,but that doesn't explain why they are great. Hundreds of boys played in those Brazilian streets,but only one became Pele.The greatest play-ers are born with some unique quality that sets them apart from all the others.The author attributes a soccer player's success to all the following factors EXCEPTA: his family backgroundB: his neighbourhoodC: his practiceD: his height

共用题干第二篇Protection of WildlifeDemands for stronger protection for wildlife in Britain sometimes hide the fact that similar needs are felt in the rest Europe.Studies by the Council of Europe,of which 21 countries are members, have shown that 1 percent of reptile species and 24 percent of butterflies are in danger of dying out.European concern for wildlife was outlined by Dr. Peter Baum,an expert in the environment and nature resources division of the Council,when he spoke at a conference arranged by the administrators of a British national park.The park is one of the few areas in Europe to hold the Council's diploma for nature reserves of the highest quality,and Dr. Baum had come to present it to the park once again.He was afraid that public opinion was turning against national parks,and that those set up in the 1960s and 1970s could not be set up today. But Dr. Baum clearly remained a strong supporter of the view that natural environments needed to be allowed to survive in peace in their own right.No area could be expected to survive both as a true nature reserve and as tourist attraction,hewent on.The short view that reserves had to serve immediate human demands for outdoor recreation should be replaced by full acceptance of their importance as places to preserve nature for the future."We forget that they are the guarantee of life systems,on which any built-up area ultimately depends,"Dr. Baum went on,"We could manage without most industrial products,but we could not manage without nature.However,our natural environment areas,which are the original parts of our countryside,have shrunk to become mere islands in a spoiled and highly polluted land mass."Although it is difficult nowadays to convince the public of the importance of nature reserves,Dr. Baum felt thatA:people would support moves to create more environment areasB:people would carry on supporting those national parks in existenceC:existing national parks would need to be more independent to surviveD:certain areas of countryside should be left undisturbed by man
