The other day, I met an old man whose name was Ted, 91 years old. He told me about his(believable) unusual story. He had lived through the Great Depression, served in the defence force and worked onfarm. He was so knowledgeable that he knew a lot in many areas of life. He was building model carts(手推车)that day. His pale hands reached out to a folder on the table, and he(take) out some photos. In the photos I saw his collection of model carts. Ted took me through each photo and explainedwas in each photo. He started telling me about how he cut steel(build) his model carts. He seemed very(enthusiasm). He gave me some valuable life(lesson). He repeatedly kept saying that (learn) is very important in life.(impress) by his love and enthusiasm for life at the age of 91, I realized that there can't be any barriers in lifewe impose (把……强加于) those barriers on ourselves.

    The Crowne Plaza Hotel in Copenhagen is offering a free meal to any guest who is able to produce electricity for the hotel on an exercise bike linked to a generator (发电机). The idea is to get people fit and reduce their carbon footprint. Guests will have to produce at least 10 watt hours of electricity — roughly 15 minutes of cycling for someone of average fitness. Guests staying at Plaza Hotel will be given meal tickets worth $ 36 once they have produced 10 watt hours of electricity. The bicycles will have smart phones attached to the handlebars measuring how much power is being generated for the hotel.

    The plan, a world-first, will start on 19 April and run for a year. Only guests staying at the hotel will be able to take part. Frederikke Toemmergaard，hotel spokeswoman, said, “Many of our visitors are business people who enjoy going to the gym. There might be people who will cycle just to get a free meal, but generally I don't think people will take advantage of our programme.”

    Copenhagen has a long-standing cycling tradition and 36 % of locals cycle to work each day, one of the highest percentages in the world, according to the website visitcopenhagen. dk. US environmental website treehugger. com recently voted Copenhagen the world's best city for cyclists. “Because Copenhagen is strongly connected with cycling, we felt the bicycle would work well as a symbol of the hotel's green profile (形象).”

    If successful，the electric bicycle meal programme will be spread to all Crowne Plaza hotels in the UK, the hotel said in a statement.

    I had heard of the killers that helped whalers catch huge whales. When I worked at a whaling station，I  it many times. One afternoon，I heard a loud noise coming from the bay. We ran down to the shore  time to see an enormous animal throwing itself out of the water. George，one of the whalers，told me that it was Old Tom，the killer，who was telling us there's a whale. Another whaler out to  a whale hunt. We immediately headed out into the bay，with Old Tom  us the way. Using a telescope we saw that several killers the whale were throwing themselves on top of the whale's blow­hole to stop it  while others were stopping it diving or  out to sea. Then the man in the bow of the boat aimed at the whale and killed it. These killers  harmed or attacked people. Once when we were in the bay，the sea was ，for which James was carried away by waves. Worse still，there was a shark. Fortunately，Old Tom rescued James.
