Before we start a voyage, we usually try to find out more or less definitely where we are bound and how we are supposed to get there. I happen to have the "Concise Oxford dictionary" on my desk and that will do as well as any other. The word I am looking for appears at the bottom of Page 344. edition 1912. "Geography: the science of the earth's surface, form, physical features, natural and political divisions, climate, productions and population." I could not possibly hope to do better, but I still stress some of the aspects of the case at the expenses of others, because I intend to place man in the centre of the stage. This book of mine will not merely discuss the surface of the earth and its physical features, together with its political and natural boundaries. I would rather call it a study of man in search of food and shelter and leisure for himself and for his family and an attempt to his background or has reshaped his physical surroundings in order to be comfortable and well nourished and happy with his limited strength. Among the two million human beings in the world, there is of course the widest possible range for all sorts of experiments of an economic and social and cultural nature. It seems me that those experiments deserve our attention before anything else. For a mountain is after all merely a mountain until it has been seen by human eyes and has been walked on by human feet and until its and slopes and valleys have been occupied and fought over and planted by a dozen generation of hungry settlers. The Atlantic Ocean was just as wide and deep and as wet and salty before the beginning of the 13th century as after, but it took the human touch to make it what it is today--a bridge between the New World and the Old, the highway for the commerce between East and West. For thousands of years the endless Russian plains lay ready to offer their abundant harvest to whoever should take the trouble to sow the first grain. But the aspect of that country today would he a very different one if the hand of a... The author mentioned the Russian plains and the island of Nippon to show that _ . A) they both feed a lot of people B) they enjoy very good natural conditions C) different people may make the same place different D) their natural conditions haven't changed for many years

Ques: Water skiing is a sport with many social, economic and health benefits to society. It is unique in that it is a sport where able and disabled persons, and people as young as 5 years and as old as 80 years of age can participate alongside each other. It is a sport that involves more than one person, and is a wonderful family activity that gathers members together for a day of fun at a favorite waterway. Anyone who has put on water skis can attest to its health benefits--it is a sport that demands and develops strength, agility and endurance. The sport includes several disciplines including slalom, tricks, cable, jump, ski racing, kneeboard, wakeboard, and barefoot, with each of these practiced for either recreational or competitive enjoyment. Safety Tips for Water-Skiers Don't take unnecessary risks while water-skiing. The following tips will help you safely enjoy this thrilling sport: ALWAYS have an observer in the boat. This is a legal requirement in many states. The boat driver cannot watch the skier and operate the boat safely at the same time. ALWAYS wear a Coast Guard approved Personal Flotation Device (PFD) designed for water skiing. Ski belts are NOT recommended. Your approved PFD will help keep you afloat. NEVER ski in rough water. High waves or a choppy sea will prevent the tow boat from maintaining a steady course and speed. NEVER ski after dark. It is dangerous AND illegal. Any boat traveling fast enough to tow a skier is traveling too fast to navigate safely at night. NEVER water-ski while under the influence of alcohol or drugs. Such activity is extremely dangerous because of the impairment to your judgment and ability to respond. A recent study conducted with expert skiers who were purposely drunk indicated that even their ability to ski was dramatically reduced. Use hand signals between the skier and observer. Agree before you start what each signal means so there is no confusion at a critical moment. Who can accompany you to go water skiing? A) A pupil in a primary school. B) A person who is disabled. C) A family member. D) All above.
Ans: D
In tests, it shrank breast tumours by 80 percent and researchers believe it could also treat prostate, pancreatic, bowel and ovarian cancers. Even tumours that resist treatment with the best medicines on the market, including the "wonder drug" Herceptin, may surrender to the vaccine. The experiments so far have been on mice - but researchers hope to pilot the drug on people within two years. If all goes well, the vaccine could be on the market by 2020. Rather than attacking cancer cells, like many drugs, the new treatment arouses the power of the immune system to fight tumours. The search for vaccines has been prevented by fears that healthy tissue would be destroyed along with tumours. Researchers from the University of Georgia and the Mayo Clinic in the US focused on a protein called MUC1 that is made in bigger amounts in cancerous cells than in healthy ones.Not only is there more of it, but a sugar that it is "decorated" with has a distinctive shape. The vaccine trains the immune system to recognise the rogue sugar and turn its weapons against the cancer. "Cancer cells have a special way of thwarting the immune system by putting sugars on the surface of tumour cells so they can travel around the body without being detected," researcher Professor Sandra Gendler said. "To enable the immune system to recognise the sugar it took a special vaccine that had three parts to it. "She said it was this that "turned out to be a winning combination". Which of the following might the writer agree with? A) The vaccine could treat nine in ten fatal cancers. B) The vaccine could be on the market within two years C) Healthy tissue might be destroyed by the vaccine. D) The vaccine could teach the immune system to recognise the rogue sugar.
