Global warming is one of the most serious problems facing humans and greenhouse gases are the main cause of it. Greenhouse gases are produced not only by industry but also by individuals (个人). People use energy to drive cars, make homes {#blank#}1{#/blank#}(comfort) and grow and transport food. Finding{#blank#}2{#/blank#}(solve) to the problem of greenhouse gases is not only a political subject but an individual one as well.

    Look for ways {#blank#}3{#/blank#}(reduce) energy at home. Turn off electrical appliances (家用电器) that you are not using. Replace your light bulbs with energy-efficient light bulbs.

    Eat locally. A lot of energy{#blank#}4{#/blank#}(use) to transport food over long distances,{#blank#}5{#/blank#}burns much fuel. Much of the same food may be grown on local farms. Shop at your local farmers, market. Plant your own vegetable garden.

Make your house {#blank#}6{#/blank#}eco-friendly one. Put a sweater on to keep warm rather than turning the heating on. Plant a tree to provide shade in summer so you don't have to use an air conditioner.

    Reduce and recycle. Be careful {#blank#}7{#/blank#}the products you buy. Recycle all paper, plastic, glass and aluminum (铝) cans.{#blank#}8{#/blank#} (when) you go shopping, please choose items that come with small packaging and that {#blank#}9{#/blank#}(be) reusable. Use your own canvas bags for shopping instead of plastic or paper bags.

    Be energy-conscious of transportation. Walk, ride a bike {#blank#}10{#/blank#}take a bus instead of driving.

    One night, Mrs Riley,{#blank#}1{#/blank#} elderly woman was walking along a dark, London street. She was carrying her handbag in one hand and a plastic carrier bag in the other. There was nobody else in the street{#blank#}2{#/blank#}two youths. They were standing in a dark shop doorway. One of {#blank#}3{#/blank#}was very tall with fair hair while the other was short and fat with a beard.

    The youths waited for a few moments, and then ran quickly and {#blank#}4{#/blank#} (quiet) towards Mrs Riley. The tall youth held her from behind while the other youth tried {#blank#}5{#/blank#}(seize) her handbag.

    Suddenly, Mrs. Riley {#blank#}6{#/blank#}(throw) the tall youth over her shoulder. She crashed into the other youth and they both landed on the ground. Without {#blank#}7{#/blank#}(speak), Mrs. Riley struck both of them on the head with her handbag, and walked calmly away.

    The two{#blank#}8{#/blank#}(surprise) youths were still sitting on the ground when Mrs. Riley crossed the street towards a door, above {#blank#}9{#/blank#}there was a lighted sign. Mrs. Riley paused, turned round, smiled at the youths and walked {#blank#}10{#/blank#}the South West London Judo(柔道) Club.

    Qingdao lies in the east of Shandong Province. As we all know, it is an important port city and it is an economic and {#blank#}1{#/blank#}(culture)center. It is also home to the Tsingtao Brewery Co. Ltd. and the {#blank#}2{#/blank#}(large)international beer festival in China. Of course, Qingdao is a very beautiful city, too. Many places around the city are well worth {#blank#}3{#/blank#}(visit).Every year, the festival {#blank#}4{#/blank#}(hold)on schedule. Millions of visitors {#blank#}5{#/blank#} come from the world go to the city during the festival.

    It is very convenient to go to Qingdao. It is {#blank#}6{#/blank#}(rough)650 kilometers from Beijing with an average travel time of one hour and 10 minutes by air and five hours by high-speed train. It is about 740 kilometers from Shanghai, and it {#blank#}7{#/blank#}(take)about one hour and 25 minutes by air. There are also frequent direct {#blank#}8{#/blank#}(flight)from Qingdao to the Republic of Korea and Japan.

Warmly welcome to Qingdao!

    Now, I'd like to tell you about the development of computers. Computers began {#blank#}1{#/blank#} a calculating machine in France in 1642, it could {#blank#}2{#/blank#} (simple) difficult sums. In 1936, Alan Turing wrote a book about how a computer could be made to work as a "universal Machine" {#blank#}3{#/blank#} (solve) any difficult mathematical problem. By the 1940s, computers had grown as large as a room. As time went by, they were made {#blank#}4{#/blank#} (small). Since the 1970s computers {#blank#}5{#/blank#} (use) in offices and homes, first as personal computers and then as laptops.

    As computers' memory improved, computers became much smaller and more {#blank#}6{#/blank#} (intelligence). First the memory was stored in tubes, then on transistors and later on very small chips. Over time computer's memory {#blank#}7{#/blank#} (develop) so much that computers remember everything they have been told. In the early 1960s computers could be connected to each other by the network {#blank#}8{#/blank#} (call) the World Wide Web.

    Many new {#blank#}9{#/blank#} (apply) have been found for computers since the1970s. They have been used in communication, finance, trade, robots, mobile phones, space rockets and so the goal of computers is to provide humans {#blank#}10{#/blank#} a life of high quality.
