51 A Honesty, my mum always used to tell me, is the best policy. Of course, this didin’t include her when she told me that if I didn’t eat all my vegetables Father Cristmas would find out and wouldn’t give me any presents. Bt when it comes to medicine, I had assumed it was important to always be honest with my patients. Ater all, the doctor patient relationship is based on trust, and therefore honesty is essential, Or so I thought. I had just started working in geriatrics(老年病科). Mr. McMahon was brought in when his baby was faound very swollen. I took a medical history from his daughter would accompanied him in the ambulance. She’d been his main carer for years. I stood looking at him as she gave a detailed history. “Has he lost any weight recently?” I asked, “Well, it’s funny you should mention that, but yes.” She said slowly. There was silence for a few moments. “Why? What are you worried about?” she asked, I hesitated. She was obviously very involved in his care and it was only fair that I told her the truth. “Well, we need to prove it’s not cancer.” I said and talked briefly about some of the tests I was going to order. Half an hour later, a nurse called me: “Mr. McMahon’s daughter broke down－she said you told her he had cancer.” My heart sank. B the time I arrived at the ward, my consultant was already there, explaining that we still had to run lots of tests and that it was by no means confirmed that he had cancer. I stood silently at the end of the bed. My consultant was obviously angry with me and as we left Mr. McMahon, she turned to me. “Why on carch did you do that?” she asked to disbelief. I looked at her andbit my hp. “She asked me what I was worried about and I told her.” I said, hanging my head. “Ad give her more to worry about?” replied my consultant. “You don’t say the word ‘cancer’ until it’s confirmed. Een if you suspect it, think very carefully before you tell people.” A it turned out, it wasn’t cancer. Bt I did learn that when somecone is stressed and worried about their loved one they’re sometimes selective in what they hear－and as a doctor it’s important to be mindful of this. In being truthful, I’d made the situation worse. .The purpose of the first two paragraphs is to show that the author .

55 B Howling is a behavior commonly observed among a wolf nark. A animals, wolves work together to hunt and rely on howling was an important means of communication each other. There are different explants of a wolf’s howl and it appears that there may be more to discover. One theory is that wolves howl to bend better together. It’s almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together . Bt this theory may be wrong, explains Fred H. Harington, a professor who studies wolf behavior. Indeed, there have been tines when wolves have been seen one moment howling in a exhorts, and the next, quarreling anions each other. It appears that usually the lowest-tanking menthes of the pack may actually be “punished” for Joining in the churs at times. So is howling a way to strcagthen a social boad or just a way to reconfirm status among its members? ——Why do welves howl for sure? What is cleat, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that woloves may separate from one another at times. When this happens, howling appcars to be an ercellent means of gathering. Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occat in the morning, as if wolves were doing some sotr of “roll rall”where wolves all howl togeter to howl, very likely others will follow.

59 C In today’s throw away society, dealing with the city’s growing mountain of waste is an inereasing challenge for the city countil(市议会)。 Recently. Einburgh is faced with the problem of dssposing of(处理)about250,000 Million tons of waster a year . Dspite different ways to dispose of much of it in a green manner---largely through encouraging tecycling---its aging facilities such as the Powderhall landfill do not have the ability to deal with it. The Eropean UnionE)has issued a new policy, regulating how such mountains of waster are to hr disposed of. The five councils (Einburgh. Est Lothian. West Lothian. Midlethian and Brders) face fine around $18million a year from 2013 it they don’t inerease recycling levels and rely less on landfill. With this in mind, the coumlls got together with the idea of building a lage incinerator plant (垃圾焚烧厂)to burn half of the waste produced in their districts. Bt the plan fell apart after the change of target levels by a new UK government waste policy which required that no more than 25% of the city’s waste should be disposed of in this way by 2025. Ater the plan was abandoned, a private company which already transported millions of tons of the city’s wast by train to a landfill site near Dnbar, offered an alternative soution when it suggested opening a huge waste site near Portobello. Since Powderhall is supposed to close in 2015, it seemed necessary for the members of the Einburgh Cuncil to accept the suggestion. Bt soon they turned it down—after 700 local objections reached them—because it would have meant hundreds of lorries a day making loud noise through heavily populated areas. That still leaves eth council with a problem. B 2013,only50%of 1995 levels of waste will benllewed to be sent to landfill. Een if recveling large are met, there will still be a large amount of rubbish to be burnt up. De build an Einburgh and Midlothian councils have now decided to work together to build an ineinerator plant as time to find a solution is fast running out. . The main way of handling waste in a green manmer in Einburgh is . (A) recyeling (B) restoring (C) burying (D) burning
