Study Says Dogs Can Smell CancerDogs are known for their sense of smell. They can find missing people and things like bombs and illegal drugs .Now a study suggests that the animal known as man's best friend can even find bladder（膀胧）cancer.Cancer cells are thought to produce chemicals with unusual odors（气味）.Researchers think dogs have the ability to smell these odors,even in very small amounts,in urine（尿）.The sense of smell in dogs is thousands of times better than in humans.The study follows reports of cases where,for example,a dog showed great interest in a growth on the leg of its owner. The mole（痣）was later found to be skin cancer.Carolyn Willis led a team of researchers at Amersham Hospital in England.They trained different kinds of dogs for the experiment. The study involved urine collected from bladder cancer patie nts,from people with other diseases and from healthy people.Each dog was tested eight times.In each test there were seven samples for the dogs to smell.The dog was supposed to signal the one from a bladder cancer patient by lying down next to it.Two cocker spaniels（短腿长毛垂耳小猎犬）were correct fifty-six percent of the time. But the scientists reported an average success rate of forty-one percent.As a group,the study found that the dogs chose the correct sample twenty-two out of fifty-four times .That is almost three times more often than would be expected by chance alone.The British Medical Journal published the research .In all,thirty-six bladder cancer patients and one hundred and eight other people took part.During training,all the dogs reportedly even identified a cancer in a person who had testedhealthy before the study.Doctors found a growth on the person's right kidney（肾）.Bladder cancer is the ninth most common cancer worldwide.The International Agency for Research on Cancer says this disease kills more than one hundred thousand people each year. Doctors say cigarette smoking is the leading cause of bladder cancer.The person who had tested healthy before the study______.A: dropped outB: passed awayC: was found to have cancerD: was found to remain healthy

Unlocking the Human Genome（基因组）1 A project to unlock secrets一what scientist could resist that challenge?This is what many scientists are doing as they work on the Human Genome Project.The aim of the project is to decode（破译）all of the some 100,000 genes in the human body. Scientists are using DNA fingerprinting techniques to do the decoding.2 DNA is the substance found in the chromosomes（染色体）of a cell. A chromosome is a chain of genes.Each gene carries a piece of genetic information.At any one moment in a cell, thousands of genes are turned on and off to produce proteins（蛋白质）.The challenge for scientists is to find out what role each gene plays in protein production.At some point this decoding will be complete.Then scientists will have a map of an ideal genome,or a picture of the total genetic nature of a human being.The ideal genome is called a consensus（交感）genome. Everything works well in a consensus genome.3 But no one in the world has a consensus genome.Everyone's genome is different from the ideal. These differences are referred to as genetic mutations（突变）.Genetic mutations in a person's genome mean that the person has a greater than average chance of suffering from health problems.Some problems are not life-threatening.These would include things like colorblindness,or mild headaches.Other problems are serious,such as heart disease,or cancer.4 It will take years to identify the role of each of the 100,000 genes.The short-term goal of the project is to find the physical and mental health problems a person is likely to encounter during his or her lifetime.The long-term goal is to have each person live a longer,healthier life.Genetic mutations in a person's genome may affect_________.A:that person's healthB:a scientific answerC:scientific researchersD:the genesE:the functionF:the size

问答题Some people think that financial disparity affects friendship. What do you think? The following article is discussing this issue. Read it carefully and write your response in about 300 words, in which you should: 1. summarize briefly the main opinion of the article; 2. give your comment. Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks. When people with money are friends with people of modest means the disparities don’t typically end with the bank accounts. One person in the friendship often feels less comfortable than the other, and it tends to be the one with less money—the friend who can’t afford to join the group at the restaurant or go on the weekend trip, the one whose share may be paid for by the others. “It doesn’t disturb the rich ones to pay,” says Horst Heidbrink, a psychology lecturer at the distance learning University of Hagen. “The rich person thinks they’re being caring. But the poorer person feels under pressure to be particularly nice.” But a lack of balance puts pressure on many friendships. Aristotelian ethics would suggest dealing with the imbalance with increased devotion by the friend with less. Friendship expert Horst Heidbrink says he wouldn’t recommend this, but his research has shown him that the give and take between friends has to be balanced. Friendships between rich and poor people are not as unusual as one might think. In a 2014 study by the Bremen-based Allensbach Institute, 1,624 people of different ages were asked about their friendships. Forty-four percent of respondents said they had friends who were considerably better off than they were. And 41% said they were friends with people who were considerably less well off than they were. And yet that old saying to the effect that money issues can put an end to friendship still holds for many. According to the study, friends helped each other out with moving house and renovation work, offered an ear when needed and doled out advice. But only 10% ever accepted significant loans from their richer friends. “Many people believe that borrowing money would weigh the friendship down,” Heidbrink says. “Most people would rather go to their parents because family relationships don’t depend on symmetry as much as friendships do.” Nevertheless, he says, “A good friendship can also withstand a credit.” Although friendships between men and women are vulnerable because they are defined by different activities. With their male friends, men play sports, for example, while women and their girlfriends often just talk when they get together. “That’s where it gets harder to leave out financial situations, and there’s more comparing,” says Heidbrink. On the other hand, when two guys play soccer together, it’s not an issue if one returns to a villa and the other to a low-rent apartment. “What counts is trust,” Heidbrink says. When trust isn’t justified—when a friend refuses to help or betrays confidences—then friendships fall apart. They don’t fall apart because one person has a lot of money in the bank and the other doesn’t. If the less well-off don’t suffer from jealousy or envy, and the better-off don’t take it too much to heart if their best friend can’t join them on that spa trip, there’s a good chance of a successful friendship.
