In 1977, a dead author of detective stories saved the life of a 19-month-old baby in a most {#blank#}1{#/blank#}(usual) way. The author was Agatha Christie, one of the most successful writers of detective stories in the world.

    In June that year, a baby girl became {#blank#}2{#/blank#}(serious) ill in Qatar, near Saudi Arabia. Doctors were unable to find out the cause of her illness with {#blank#}3{#/blank#}(confident), so she was sent to big hospital in London {#blank#}4{#/blank#}specialist help was available. A team of doctors hurried to examine the baby only {#blank#}5{#/blank#}(discover) that they, too, were confused by the very unusual disease. Just then, a nurse asked to speak to them.

     "Excuse me," said the nurse, "{#blank#}6{#/blank#} I think the baby is suffering from thallium(铊) poisoning. "

    "What makes you think that?" Dr. Brown asked. "Thallium poisoning is extremely rare."

"I read a detective novel {#blank#}7{#/blank#} Agatha Christie a few days ago,” the nurse explained, "and in the book, somebody suffers from thallium poisoning, and all the symptoms {#blank#}8{#/blank#}(describe). They're exactly {#blank#}9{#/blank#} same as the baby's."

    The tests showed that the baby had indeed been poisoned by thallium, a rare metallic substance{#blank#}10{#/blank#} (use) in making special glass. Once they knew the cause of the illness, the doctors were able to give the baby the correct treatment. She soon recovered and was sent back home.

    How are you getting along with your senior high school? It may be hard for you as this is the first time that you {#blank#}1{#/blank#}(leave)your parents. I know that you are now having trouble {#blank#}2{#/blank#}(communicate)with others, and you may often feel lonely. That's {#blank#}3{#/blank#}you are new here and people don't know about you. But I think you can overcome the difficulty if you can follow the advice below.

    First, you should attach great{#blank#}4{#/blank#} (important) to taking an active part in the discussions and show our own opinions about the matters, and at the same time, learn to listen to other people's views {#blank#}5{#/blank#} (careful). Second, you should learn about your classmates' likes and dislikes,{#blank#}6{#/blank#}can make you get familiar with them. Only in this way can you get to know more {#blank#}7{#/blank#} (difference)people and show them that you are just as friendly. Last but not least, I'm always here ready to help. We can take part in some {#blank#}8{#/blank#} (activity)together and I can introduce you to others.

    There's no need{#blank#}9{#/blank#} (worry)too much, people will know you more very soon and will like to make friends {#blank#}10{#/blank#}you if you can do as the above. Just remember, “God helps those who help themselves.”

    After giving a talk at a high school, I was asked {#blank#}1{#/blank#} (pay) a visit to a special student. An {#blank#}2{#/blank#} (ill) had kept the boy home, but he had expressed an interest {#blank#}3{#/blank#} meeting me. I was told it would mean a great deal to him, so I agreed.

    The thirteen-year-old, {#blank#}4{#/blank#} had muscular dystrophy（肌肉萎缩症）, wanted to meet me because I was a gold-medal power lifter, and I knew how to deal with difficulties.

    I spent over an hour talking to him. Never once {#blank#}5{#/blank#} he complain or ask, “Why me?” He spoke about going for his dreams. {#blank#}6{#/blank#} (obvious), he knew what he was talking about. He didn't mention his classmates had made fun of him because he was {#blank#}7{#/blank#} (disable). He just talked about his hopes for the future. When we had finished {#blank#}8{#/blank#} (talk), I pulled out {#blank#}9{#/blank#} first gold medal I had won and put it around his neck. He looked at it for a moment, then {#blank#}10{#/blank#} (take) it off and handed it back to me. He said, “Someday when I get to the Olympics and win my own medal, I will show it to you.”

    Iceland is a land of volcanoes. Nowhere is {#blank#}1{#/blank#}（evident） than on the Westman Islands off the southern coast of Iceland. Here, {#blank#}2{#/blank#}（century） of volcanic eruptions formed many eye-catching sea cliffs （悬崖）, among {#blank#}3{#/blank#} one stands out: A part of the volcano-formed coast on Heimaey looks exactly like the head of a large elephant {#blank#}4{#/blank#}（stick）its trunk in the water.

    In fact, it looks so much like an elephant that many people think it must have been shaped by humans. That is not {#blank#}5{#/blank#} case, however. The elephant's realistic {#blank#}6{#/blank#}（appear）is, at least partially, due to the fact that the cliff {#blank#}7{#/blank#}（consist）of a special rock. The rock gives the figure "skin" that looks wrinkled and gray, just like that of a real elephant.

    The most common theory is that the rock formations came from the Eldfell Volcano, which {#blank#}8{#/blank#}（erupt）many times since the 1940s.

    In spite of the strong resemblance to an elephant, some people {#blank#}9{#/blank#}（actual）see something different when they look at the rock formation. They see the fictional character Cthulhu, a sea beast.

    Whether you see an elephant {#blank#}10{#/blank#} a fictional beast, as one of many attractions on Heimaey, the rock does draw curious sightseers.

    Walking is the UK's most popular sport. It has {#blank#}1{#/blank#} interesting history. In April 1932, 400 people {#blank#}2{#/blank#} (leave) Manchester and Sheffield in Northern England to walk across Kinder Scout in the Pennines. They fought {#blank#}3{#/blank#} the fact that only rich people, {#blank#}4{#/blank#}went there to kill birds, could visit this beautiful area. Because of the walk, National Parks in England and Wales finally began in 1949, as well as the Pennines Way, one of twenty long, {#blank#}5{#/blank#}(wonder) paths.

    You don't have to walk the whole way if you are on one of the long paths. And there {#blank#}6{#/blank#} (be)a great number of shorter paths for you to choose. But there are afew basic {#blank#}7{#/blank#} (rule) you should follow. Don't drop paper and plastic; close gates after you; keep dogs on lead(绳索)if there are farm animals in the area; stay on the path.

    Also, remember that British weather can change very quickly, {#blank#}8{#/blank#} (especial) in the hilly north and west of the country. If you are in Wales, Scotland {#blank#}9{#/blank#} the north of England, carry plenty of food and water, as well as warm clothes. National Parks and footpaths are the best way {#blank#}10{#/blank#}(enjoy).

    Britain's glorious, varied countryside.

    Should naps(小睡) actually {#blank#}1{#/blank#} (take) during the day? Well, we certainly know from {#blank#}2{#/blank#} (evident) in the sleep center and that of many other scientists that naps can give you benefits for both your brain {#blank#}3{#/blank#} your body. But naps can actually be {#blank#}4{#/blank#} double-edged sword because while we're awake during the day, we're building up sleepiness or sleep pressure. So when you try to fall asleep at night, you'll fall asleep quickly and then you'll stay asleep. And when we sleep, we actually release that sleepiness so that we wake up the next morning feeling {#blank#}5{#/blank#} (refresh).

    So if you take a nap during the day, especially if you take it too late in the afternoon, you will actually release some of that sleepiness and it will make it much {#blank#}6{#/blank#} (hard) to fall asleep and stay asleep soundly throughout the night. So the advice would be if you don't struggle with your sleep and you can nap{#blank#}7{#/blank#} (regular), then naps are just fine.

    But if you do find it difficult {#blank#}8{#/blank#} (fall) asleep or stay asleep at night, then you should avoid naps and try to build up that healthy sleepiness in the evening.

    The ideal nap depends on {#blank#}9{#/blank#} you want from that nap. Different stages of sleep actually give you different types of brain and body  {#blank#}10{#/blank#} (benefit).
