At four o’ clock, P work and stepped out into the fog. She wondered if the buses would still be running. No buses toKing StreetOnce out in the street, she walked quickly towards her usual bus stop. ‘ Howfar are yougoing? ’the bus conductor asked her before he took her fare. ‘ KingStreet, said’ Polly. ‘ Sorry,Miss, ’replied the man, ‘ thetruth is that it is too foggy for the bus to run that far. Take theUnderground to Green Park. The weather might be better there and you might be able to get ataxi.’A tall manAs Polly observed the passengers on the train, she had a feeling that she was being watchedby a tall man in a dark overcoat. At last the train arrived at Green Park station. While the rest ofthe passengers were getting out, she glanced at the faces around her. The tall man was nowhere tobe seen.When Polly got to the station entrance, it was empty. Outside, wherever she looked the foglay like a thick, grey cloud. There was no one in sight. Polly set off towards Park Street. As shewalked along the narrow street, she heard the sound of footsteps approaching, but by the time shereached the corner of the street, the footsteps were gone. Suddenly Polly felt a rough hand brushher cheek, and she heard a man ’ s voice in her ear saying ‘ Sorry. ’ The man moved away. She feel her heart beating with fear.The helpful strangerThen she heard the sound again— soft footsteps behind her. A minute before, she had wishedfor someone to come along. Now she wanted to run, but fear held her still. The footsteps seemedclose now. Then a man’ s voice came out of the darkness.‘ Is anybody there?’Polly hesitated. At last she answered,‘ Hello, I think I’ m lost.’A few seconds later, a hand reached out and grasped her arm. Polly found herself staring upat the face of an old man with a beard. ‘ MaybeI can help you. Which road do you want? ’heasked.‘ I live at 86 King Street,’ Polly replied.‘ Just take my hand,’ said the man.‘ Come with me. You’ ll be all right.’ He took Poll ‘ Watch out for the step here.’In his other hand the man carried a stick. Polly heard it hit the step.‘ I can remember someterrible fogs, but maybe that was before your time. I can’ t see your face, but you sound young. How old are you?’‘ Just twenty,’ answered Polly.‘ Ah, twenty! A nice age to be. I was young once. Now wethe crossroads. Turn left here.’‘ I’ m quite lost now. Are you sure you know the way?’ Polly was beginning to feel frightened again.‘ Of course. You really shouldn’ t feel anxious.’ He held her hand more firmly.The grateful helper‘ Here we are. King Street. stopped’.He‘ Thank you so much for coming to my aid,’ said Polly in relief.‘ Would you like to comeand rest for a while?’‘ It’ s very nice of you,’ said the man,‘ but I’ ll be off. There may people lost today, and I’ d like to help them. Youfogsee,this bad is rare. It gives me the chanceto pay back the help that people give me when it’ s sunny. A blind person like me can’ t g the road without help, except in a fog like this.’雾雾警报那天早上当波莉离开家，城市已经被一层灰色的薄雾覆盖。
在午餐时间，收音机天气预报员报道薄雾在下午会变成浓雾。
四点钟，波莉离开工作，踏入雾中。
她怀疑巴士是否仍然在运行。
没有去国王街的巴士她一出来在大街上，就快速走向她以往的停车站。
“你要去的地方有多远？”巴士售票员问她。
“国王街。
”波莉回答。
“对不起，小姐。
”男人回答，“事实上，雾太浓了以至于巴士不能行驶那么远。
坐地铁列车去绿色花园，那里的天气也许会好一点，而且你也许可以在哪儿拦到一辆出租车。
”一个高大的男人当波莉观察地铁上的乘客时，她注意到她被一个穿着黑色外套的高大男人盯着。
最后，列车到达了绿色花园车站。
当其他的乘客下车，她扫视了周围人的脸，四处都找不到那个高大男人。
脚步声波莉到了车站出口，那里空无一人。
外面的雾像一朵厚厚的灰云。
在势力范围内一个人都没有。
波莉朝着公园街出发。
当她沿着街走时，她听到了脚步声，但是等到她到达街道拐角处，脚步声不见了。
突然，波莉感到一只粗糙的手轻拂过她的脸，她听到一个男人的声音在她耳边说：“对不起。
”男人离开了。
她能感觉到心脏带着恐惧的跳动声。
乐于助人的陌生人然后她再次听到了这个声音——在她后面轻轻的脚步声。
一分钟前，她希望有个人和她一起走。
现在她想要跑，但是恐惧使她一动不动。
现在脚步声似乎靠近了。
然后一个男人的声音从黑暗中传来：“有人在那里吗？”波莉顿了顿，最后她说：“你好，我想我迷路了。
几分钟后，一只手伸了出来而且碰到了她的手臂。
留在她的手臂上站立着的男人。
她看到的是一张老人的脸。
”波莉发现她自己抬头凝视着一个手停“也许我能帮助你，你要去哪里？”他问。
“我住在国王街86 号。
”波莉回答。
“只管抓住我的手。
”男人说，“跟着我走。
你会没事的。
”他抓住波莉的手：“留意这里的台阶。
”在他的另外一只手上男人拿着一根拐杖。
波莉听到拐杖敲击着台阶。
“我还记得一些可怕的雾天，但是也许那是在你出生之前。
我看不见你的脸，但是你的声音听起来很年轻。
你几岁了？”“刚满 20。
”波莉说。
“嗯， 20 岁！一个很美好的年龄。
我也曾经年轻。
现在我们在拐角处。
从这里向左拐。
”“我现在快迷路了，您确定您认识路吗？”波莉再次开始感到害怕。
“当然，你真的不必担心。
”他握住她的手更紧了。
一个感恩的帮助者“我们到了，国王街。
”他停住。
“非常感谢。
”波莉说，“你愿意进来休息一下吗？”“你真的很善良。
”男人说：“但是我要离开了。
今天也许会有更多的人迷路，我要去帮助他们。
你看，如此糟糕的雾是很罕见的。
它给了我们报答在晴天给我们帮助的人们。
一个像我这样的盲人没有帮助时不能穿过马路的，除了在像这样的雾天中。
”M3u1Project Shark attaksThere are nearly 400 different types of sharks, but only about 30 types are known to have attacked human beings. Many people know that the most dangerous shark is the great white shark, probably because they have seen the film Jaws. However, two other sharks are also rather dangerous: the tiger shark and the bull shark.To reduce the risk of a shark attack, you should follow these suggestions.?Do not swim in the dark. Sharks can still see you but you cannot see them.?Do not go swimming in the ocean if you have a fresh wound. Sharks can smell blood over a long distance.?Do not wear bright clothing or jewellery,because sharks are attracted to the flash of colours and bright objects.?Stay in groups, as sharks usually avoid large numbers of people.Recently, shark attacks have been increasing as water sports are becoming more popular. If a shark attacks you, follow the advice below.?Keep calm. Do not panic.?Hit the shark on the nose with your fist.?Stick your finger in the shark’ s eye.Don’ t be frightened by sharks: you are 30 times more likely to be hit by lightning than be attacked by a shark.鲨鱼攻击有将近400 种不同种类的鲨鱼，但我们知道只有约30 种鲨鱼攻击过人类。
