When I was growing up，I was embarrassed to be seen with my father. He was badly crippled (跛脚)，and when we would walk together，his hand on my arm for balance，people would stare，I would be ashamed of the unwanted attention.

    It was difficult to walk together—and because of that，we didn't say much as we went along. But as we started out，he always said，“You set the pace. I will try to follow you.”

    Our usual walk was to or from the subway，which was how he got to work. He went to work sick，and even in bad weather. He almost never missed a day，and would make it to the office even if others could not. It was a matter of pride for him.

    When snow or ice was on the ground，it was impossible for him to walk，even with help. At such times my sister or I would pull him through the streets of Brooklyn，N.Y.，on a child's sleigh to the subway entrance. Once there，he would try to grasp handrail until he reached the lower steps that the warmer tunnel air kept ice free. In Manhattan the subway station was the basement of his office building，and he would not have to go outside again until we met him in Brooklyn on his way home.

    When I think of it now，I am surprised at how much courage it must have taken for a grown man to suffer from shame and disability. And I am also surprised at how he did it—without bitterness or complaint.

    He never talked about himself as an object of pity，nor did he show any envy of the more fortunate or able. What he looked for in others was a “good heart”，and if he found one，the owner was good enough for him.

    Now that I am older，I believe that is a proper standard by which to judge people，even though I still don't know exactly what a “good heart” is. But I know the times I don't have one myself.

    He has been away for many years now，but I think of him often. I wonder if he sensed my reluctance to be seen with him during our walks. If he did，I am sorry I never told him how sorry I was，how unworthy I was，how I regretted it. I think of him when I complain about my troubles，when I am envious of another's good fortune，when I don't have a “good heart”．

    My grandfather came from Hungary and was the only one in his family who settled down in the United States. The rest of his family remained in Europe. When World War I broke out, he seemed to have become another man, downhearted. Such obvious change was not born out of concern for his welfare, but out of fear: if his only son, my uncle, had to go to war, it would be cousin fighting against cousin.

    One day in 1918, my Uncle Milton received his draft notice. My grandparents were very upset. But my mother, at the age of 10, felt on top of the world about her soldier brother going off of war. Realizing how he was regarded by his little sister and all of her friends, my uncle bought them all service pins, which meant that they had a loved one in the service. All the little girls were delighted.

    The moment came when my uncle and the other soldiers, without any training but all in uniforms, boarded the train. “The band played and the crowd cheered. Although no one noticed, I'm sure my grandmother had a tear in her eye for the only son. The train slowly pulled out, but not about a thousand yards when it suddenly paused. Everyone stared in wonder as the train slowly returned to the station. There was a dead silence before the doors opened and the men started to step out. Someone shouted, “The war is over!”For a moment, nobody moved, but then the people heard someone bark orders at the soldiers. The men lined up in two lines, walked down the steps, and with the band playing, marched down the street, as returning heroes, to be welcomed home. My mother said it was a great day, but she was just a little disappointed that it didn't last a tiny bit longer.

    I'm Mr. Lockwood and have been to see my landlord Mr. Heathcliff today. He was standing at the gate to his farm when I arrived. His black eyes looked at me suspiciously.

    The name of Mr. Heathcliff's house is Wuthering Heights. 'Wuthering' means 'stormy' or 'windy' in the local language and it describes the place well. The house stands on the top of a hill. On one side of it there are a few trees. They all lean in the same direction, blown by the strong north winds.

    Then we went into the sitting room. The floor was made of smooth, white stone. There was a big fireplace at one end of it and a large dresser at the other end. Several large hunting dogs were lying in the dark corners of the room. I sat down in one of the chairs near the fire. But unfortunately, when Mr. Heathcliff was out for his servant, Joseph, I was attacked by his hunting dogs.

    To my surprise, I enjoyed our conversation very much, though. When it was time for me to leave, I said, 'I'll come and see you again tomorrow'. I set out after lunch the following day. But Mr. Heathcliff wasn't in, and a young man led me to the sitting room. His manner was proud and free, so I couldn't decide if he was a servant or not. He was dressed like one and spoke like one.

    A few minutes later, Heathcliff walked in. We all drank our tea in silence and there was a very tense atmosphere in the room. I thought it was my fault so I tried to be sociable.

    This is a beautiful part of the country,' I said, 'but very isolated. However, you seem very happy here, with your wife and family…'

    'My wife!' Heathcliff exclaimed looking around him. 'Where? Are you talking about her spirit?'

    How stupid of me! Of course the girl wasn't his wife! She was much too young for him. She must be married to the young man.

    'Mrs. Heathcliff is my daughter-in-law', said Heathcliff, reading my thoughts. There was hatred on his face as he spoke.

    Ah, yes,' I said. 'You are very lucky to have such a lovely wife, young man.'

    The youth went red and looked down at his plate.

    I said she was my daughter-in-law, sir. She was married to my son,' said Heathcliff.

    And this young man is…'

    Not my son.'

    My name is Hareton Earnshaw,' growled the youth angrily.

    The atmosphere began to depress me. After a long silence I asked, 'Perhaps one of your servants is free now to take me home?'

    There's only Heathcliff, Hareton, Zillah the housekeeper, Joseph and me here', said the girl.

    Then I suppose I'll have to stay until the morning.' I replied

    That night, I was arranged in a house where the master didn't usually allow people to stay. I closed the door and got into bed. I put my candle on a small shelf next to a pile of old books. To my surprise, I saw that the shelf was covered in writing. These names were scratched in the paint: Catherine Earnshaw, Catherine Heathcliff and Catherine Linton.

    I picked up one of the books on the shelf. It was a diary. On the first page I read, 'Catherine Earnshaw, her book', and a date of twenty-five years ago. Curious to know more about this Catherine, I started to read. I understand the following: Catherine Earnshaw's father was dead and she lived with her cruel older brother Hindley. Catherine and Heathcliff were close friends, but Hindley and his young wife Frances heated and abused the adopted Heathcliff.

    I had terrible dreams that night. There was a lot of noise-rapping and tapping sounds. I woke up. The branch of a tree outside was hitting the glass in the window. I got up, pushed my hand through the glass and pout out my arm. But instead of the branch my fingers closed on a little ice-cold hand. The hand held mine tightly and a sad voice sobbed, 'Let me in!'

    Who are you?' I said.

Catherine Linton' it replied. 'I've come home. I lost my way on the moor! Let me in!"

    The number of insects in the world has fallen by 45 percent in the past 35 years. Scientists say this could be dangerous for humans. A report on insect numbers has been published in the journal "Science". It says the human population has doubled since 1980 while the number of insects has nearly halved. One of the biggest reasons for this loss of insects is the act of cutting down trees or burning them. Many of the places where insects live are disappearing because of new cities and land being used for farming. Another reason is global warming. Scientists say that in the UK, the number of butterflies, bees and wasps(黄蜂) has fallen by up to 60 percent. Many countries are worried about the disappearance of them.

    Scientists say the decline in insect populations will lead to many problems for humans. One of the biggest dangers is that there will be fewer insects to pollinate flowers. This means that farmers will have problems growing food. The lead author of the report, Professor Rodolfo Dirzo, said falling numbers of insects could also lead to more diseases in humans. He said rats and mice would have less food to eat so they will move to cities and bring diseases with them. Dr. Ben from London University said we needed to stop more insects from dying. He added that scientists must understand what species(物种) are winning and losing in the fight for survival. He said this knowledge would help us to protect the "helpful" insects.

    Not long ago, a good friend of mine asked me to help him in a halfway house in Nashville. I agreed and made my way there one evening.

    When I got there, I sat with my friend and talked about how he ended up there. As we talked, another man came up, lighting up his cigarette as he sat down. He had dark, leather skin, and looked like he had endured the sun, the rain, and the wind for long, long time. I couldn't tell how old he was, but I was sure that he was younger than he looked.

    Through a bit of conversation, I found out that he had been on the streets for many, many years.

    Without my asking, he started describing life as a homeless man. How he got food; how he stayed warm; how he got money. And he told me something that caught my attention.

    He said, "You want to know how I keep my stuff safe at night?"

    "Sure," I replied.

    "I put it up in the trees."

    "Why is it safe in the trees?" I asked.

"The homeless are always looking for treasure on the ground— coins, something someone's dropped, half-smoked cigarettes. I know if I put my stuff in the trees, they'll never find it because they never look up. Never. "

    Profound words from an unexpected place. And his message is for all of us.

We all have our particular search. We're looking for treasure on this earth. But what we are REALLY looking for is right there above us. There's really nothing we need on the ground.

    In fact, it's surrounding us.
