Nobody is sure where and when the expression “apple-pie order” began. Some say that Scottish and English writers used the expression a long time ago. Others say it was first used in the northeastern American states known as New England. The housewives of New England cut their apples in even slices. Then they filled pie pans with them in an organized way, row upon row. As one writer said, the women of New England loved to have everything in its place. This perhaps explains why it generally is believed that the expression “apple-pie order” began in New England.

    Another old expression, “apple of discord”, comes from ancient mythology(神话), however. The myth says that all the gods and goddesses were sitting around the table to celebrate the marriage of Thetis and Peleus. One of the goddesses-Discord was a troublemaker. She threw away a golden apple on the table to be given as a prize to the most beautiful goddess.

    At one time, the tomato was called a love apple. That was a mistake. This is how the mistake happened: In the sixteenth century, Spain brought the tomato from South America after Spanish explorers had landed there. Spain then sold the tomato to Morocco. Italian traders carried it on to Italy. The Italian name for the tomato was “pomo di Moro” meant “d'amour” -the French word for love. And so “pomo di Moro” became the apple of love.

    People believe many things about the apple. One belief is that it has great powers of keeping people healthy. A very common expression is "an apple a day keeps the doctor away."

    Another belief is based on fact. The expression is "one rotten apple spoils the barrel." When an apple begins to go bad, it ruins all the other apples around it in the container. The expression has come to mean that one bad person in a group can cause everyone to act bad.

    Farah was sitting in the kitchen going over the party list with her mother. The exams were over and Farah wanted to invite her friends for a party.

    “Farah, aren't you going to invite Hafsa?” her mother asked. Hafsa had been her best friend since childhood.

    “Mother, you know I am now a part of Purple Girls Club and we have some rules about people we can be friends with,” Farah answered.

    “Really? And what are the rules?” her mother asked.

    “Well, only very pretty girls can be part of our group. And Hafsa is so, you know, dark.”

    “I cannot believe it.” her mother said angrily.

    As Farah left the kitchen, her father called her from the living room.

    Farah went to her father and paled when she saw the exam report in his hands.

    “Farah, what has happened to your grades? You have failed in Mathematics.” her father said.

    Farah had no answer. The truth was that the activities of Purple Girls Club left her with very little time for studies.

    “Farah, it says that you can take part in supplementary exams(补考). If your grades don't improve then, I'll cancel your trip to Spain.”

    Farah went to her room and called Gina, the leader of Purple Girls Club.

    “Gina, can you help me to complete my notes before the exams?”

    Gina laughed, “Exams? Who cares about exams?”

    One by one, she called her friends in the club but no one seemed to care or wanted to help. Farah knew Hafsa would help her. Farah also knew Hafsa had been hurt by her, but Hafsa said, “If you need any help, just let me know. We can study together till your exams.”

    Next Monday, as two friends entered the school together. Gina called out

    “Farah, you know our rules. You cannot be friends with those who do not belong to our club.”

    “Gina I have a new rule about friendship,” Farah replied.

    When I was ten years old I went to the USA to visit some family friends. I noticed something funny about the way everyone spoke English.

    One moment! I remember very clearly was at the beginning of the holiday, when my friend asked me if I wanted to order “French fries”. I couldn't imagine what they were. She was amazed that I had never tried them and she ordered a portion for us to share. When the waiter brought us some chips, I asked her where the French fries were. She pointed at the plate of chips! Later that week she said she was going to buy some “chips” from the supermarket. She came out with a packet of crisps（薯片）! How come?

    During that holiday we were also offered “biscuits” with our lunch. This was a very strange idea to me, because in England biscuits are sweet. I later realized that “biscuits” in America are salty snacks. What we call “biscuits', they call “cookies”.

    I was also embarrassed when a stranger told me she liked my “pants”. I wondered how she could see them! My mum then told me that they call “pants” what we call “trousers”, the outer clothing that you wear on your legs instead of inside clothing!

    I was disgusted when I saw an “eggplant” pizza on the menu in a restaurant. But I was puzzled how eggs can grow on plants. My dad ordered this pizza and it was covered in aubergines（茄子）. “They call aubergines 'eggplant' in America!” he told me.

    I think part of the excitement of learning a language is learning about the differences that exist in how it is spoken in different places.

    As time went on, Philip's deformity was accepted like one boy's red hair and another's unreasonable obesity. But meanwhile he had grown horribly sensitive. He never ran if he could help it, because he knew it made his limp more noticeable. He stood still as much as he could, with his badly shaped foot behind the other. Because he could not join in the games which other boys played, their life remained strange to him; sometimes they seemed to think that it was his fault if he could not play football, and he was unable to make them understand. He was left a good deal to himself. He had been inclined to talkativeness, but gradually he became silent.

    The biggest boy in his dormitory, Singer, took a dislike to him, and Philip, small for his age, had to put up with a good deal of hard treatment. About half-way through the term there was a game called Nibs. It was a game for two, played on a table or a form with steel pens. Soon nothing was seen but boys playing this game, and the more skilful acquired vast stores of nibs. But in a little while Mr. Watson made up his mind that it was a form of gambling, and forbade the game. Then he ordered all the nibs in the boys' possession be handed in. Philip had been very skilful, and it was with a heavy heart that he gave up his winning; but his fingers itched to play still, and a few days later, on his way to the football field, he went into a shop and bought a pennyworth of J pens. He carried them loose in his pocket and enjoyed feeling them. Presently Singer found out that he had them. Singer had given up his nibs too, but he had kept back a very large one, called a Jumbo, which was almost unconquerable, and he could not resist the opportunity of getting Philip's Js out of him. Though Philip knew that he was at a disadvantage with his small nibs, he had an adventurous disposition and was willing to take the risk; besides, he was aware that Singer would not allow him to refuse. He had not played for a week and sat down to the game now with a thrill of excitement. He lost two of his small nibs quickly, and Singer was jubilant, but the third time by some chance the Jumbo slipped round and Philip was able to push his J across it. He crowed with triumph. At that moment Mr. Watson came in.

    "What are you doing?" he asked.

    He looked from Singer to Philip, but neither answered.

    "Don't you know that I've forbidden you to play that game?"

    Philip's heart beat fast. He knew what was coming and was dreadfully frightened, but in his fright there was a certain exultation. He had never been swished. Of course it would hurt, but it was something to boast about afterwards.

    "Come into my study."

    The headmaster turned, and they followed him side by side. Singer whispered to Philip:

    "We're in for it."

    Mr. Watson pointed to Singer.

    "Bend over," he said.

    Philip, very white, saw the boy quiver at each stroke, and after the third he heard him cry out. Three more followed.

    "That'll do. Get up."

    Singer stood up. The tears were streaming down his face. Philip stepped forward. Mr. Watson looked at him for a moment.

    "I'm not going to beat you. You're a new boy. And I can't hit a cripple. Go away, both of you, and don't be naughty again."

    When they got back into the school-room a group of boys, were waiting for them. They set upon Singer at once with eager questions. But he did not answer. He was angry because he had been hurt.

    "Don't ask me to play Nibs with you again,' he said to Philip. 'It's jolly nice for you. You don't risk anything."

    "I didn't ask you."

    "Didn't you!"

    He quickly put out his foot and tripped Philip up. Philip was always rather unsteady on his feet, and he fell heavily to the ground.

    "Cripple," said Singer.

    For the rest of the term he tormented Philip cruelly, and, though Philip tried to keep out of his way, the school was so small that it was impossible; he tried being friendly and jolly with him; he abased himself, so far as to buy him a knife; but though Singer took the knife he was not placated. Once or twice, driven beyond endurance, he hit and kicked the bigger boy, but Singer was so much stronger that Philip was helpless, and he was always forced after more or less torture to beg his pardon. It was that which rankled with Philip: he could not bear the humiliation of apologies, which were wrung from him by pain greater than he could bear. And what made it worse was that there seemed no end to his wretchedness; Singer was only eleven and would not go to the upper school till he was thirteen. Philip realized that he must live two years with a tormentor from whom there was no escape. He was only happy while he was studying and when he got into bed. And often there recurred to him then that queer feeling that his life with all its misery was nothing but a dream, and that he would awake in the morning in his own little bed in London.

    Some spiders hunt on the ground, others build webs to trap their food, but the grass water spider catches its prey by running along the surface of the water.

    This special water spider lives on the grassy banks of streams where mosquitoes, damsel flies and other insects come to feed and breed.

    Although it is one of the largest spiders in New Zealand, it has an unusual ability. It doesn't disturb the water as it waits for its meal, and there is barely a ripple(波纹) when it skims(掠过) across the surface at lightning speed to catch its prey.

    Grass water spiders deal swiftly with larger insects like damsel flies by pulling their heads under the water and holding them there until they drown.

    After a meal, the grass water spider spends up to half an hour grooming(修饰) itself. It wipes its eight eyes, brushes its antennae(触角), and takes special care to clean the hairs on its body.

    It is the hairs that trap tiny bubbles(泡沫) of air so that the spider can run down a blade(叶片) of grass and stay underwater for up to an hour when it is frightened. The hairs also keep the spider dry, even underwater.

    It is only when the female spider is caring for the young that she does not hunt on the water. After mating, she produces a large egg sac(囊), which she carries around for five weeks. Once the eggs start to hatch, she attaches the sac to some blades of grass or a thistle. She then tears the sac open and releases the tiny spiders into the nursery web.

    Many of us think, wrongly, that the moon doesn't change. For example, the Tang Dynasty poet Zhang Ruoxu once wrote that "Generations have come and passed away; From year to year the moons took alike, old and new."

    However, a new study published in the journal Nature Geoscience shows that the moon is in fact slowly shrinking over time. For the study, a group of US scientists examined and analyzed thousands of photographs taken by the NASA orbiter Lunar Reconnaissance Orbiter Camera (月球勘测轨道飞行器照相机) . They found that there were lots of faults (断层) on the surface of the moon. These faults were formed by recent movement on the moon.

    According to NASA, the moon is made up of pieces of rocks with a hot core (核) .The moon continued to expand as it was born. But in this process, it released energy and cooled down. Then it began to shrink, in a way comparable to the shrinking of a grape into a raisin (葡萄干) . Over the past several hundred million years, it has become 46 meters "skinnier". But due to its hard and rocky crust (外壳) . the moon's surface continues to push up, "Some of these quakes can be fairly strong around five on the Richter scale (里氏震级) ," said Thomas Watters, a senior scientist at the Smithsonian's National Air and Space Museum in the US.

    But does that mean the moon is a dangerous place that human shouldn't try to explore and live on in the future? Maybe not, reported the Telegraph, "This isn't anything to worry about. The moon may be shrinking, but not by much. It's not going anywhere," Watters comforted us.

    The new discovery proves that the idea that the moon is a dead, boring place is wrong. "We have been to the moon and we've done some great science, but there is still a lot we don't know. The moon is shrinking ­ we didn't really realize that until recently. It's a much more active and interesting place than we thought and we should explore that," NASA scientist Nathan Williams said.
