If you go out to the fields at night in spring or summer, you can hear frogs singing{#blank#}1{#/blank#}(joy) here and there. It seems as if they were performing a field symphony（交响乐）.

    The frog is a good and useful creature that benefits human beings. They can catch fast-moving insects. Each frog eats a large number of pests that are {#blank#}2{#/blank#}(harm) to crops. This little creature is regarded {#blank#}3{#/blank#}“the natural enemy of pests”.

    {#blank#}4{#/blank#} now frogs are getting fewer and fewer. This is{#blank#}5{#/blank#}they are killed and put on the table as a delicious dish by their chief enemy, human beings. It is a shameless and cruel act, isn't it? Another reason responsible for the rapid reduction of frogs is {#blank#}6{#/blank#}farmers use insecticides (杀虫剂) to kill pests and frogs get {#blank#}7{#/blank#}(kill)as a result of drinking poisoned water or eating poison-killed insects.

    Something must be done without delay {#blank#}8{#/blank#}(save) frogs. If we don't punish those {#blank#}9{#/blank#}sell and kill frogs to make money, then one day all of us {#blank#}10{#/blank#}(punish) by nature for failing to keep the balance of nature.

    “Mirror, mirror, which clothes suit me best?” Now, there is a magic mirror in the shopping center{#blank#}1{#/blank#} can answer the question.

    A shopping center in England is selling a magic dressing mirror. You needn't enter a fitting room and put the clothes{#blank#}2{#/blank#} by yourself. All you need to do is to stand in front of the mirror. The magic mirror can tell you{#blank#}3{#/blank#} or not the clothing you have chosen suits you.

    3D technology {#blank#}4{#/blank#} (use) for the magic mirror for you to choose and try on all kinds of clothes from different stores. When you stand in front of the mirror. With the {#blank#}5{#/blank#} (assist) of the technology, you can make its own judgement of your body type. Then you can see {#blank#}6{#/blank#}wearing the dress you have chosen in the mirror.

    It's very convenient for you to find the most{#blank#}7{#/blank#} (suit) dress. You do not have to spend a lot of time {#blank#}8{#/blank#} (walk) around in different stores.{#blank#}9{#/blank#} do you need to shut yourself into a small dressing room.

    “The mirror has worked much better with women's clothing than {#blank#}10{#/blank#} (expect), so we are now developing the software for men's and kid's clothing,” said the marketing manager of the shopping center.

    If you've ever heard of someone being in the right place at the right time, you've likely never heard it fit a story as well as this one. In 2014, a 17-year-old volunteer firefighter {#blank#}1{#/blank#}(call) Joseph Chambers heard {#blank#}2{#/blank#} loud crash outside of his sister's home. Joseph found two cars {#blank#}3{#/blank#}what appeared to be a fatal collision, one of {#blank#}4{#/blank#}was a police patrol car. He{#blank#}5{#/blank#}(immediate) ran up to the car of Officer Mark Kimsey{#blank#}6{#/blank#}(see)if he was okay. Officer Kimsey {#blank#}7{#/blank#}(trap), but Joseph sprung into {#blank#}8{#/blank#}(act), pulling Kimsey out through the window with another bystander as his patrol car burst into{#blank#}9{#/blank#}(flame). Maybe it was Joseph's firefighter training that allowed him to think, and act, so quickly, but it's certain that he saved a man's life that day without once{#blank#}10{#/blank#}(think)about his own well-being.

UK Schools Ban Students From Using Slang (俚语)

    Officials at Sheffield's Springs Academy has introduced a new policy to prevent students aged 11 to 18 {#blank#}1{#/blank#} (use) slangs and colloquial abbreviations (口语化的缩写) inside the school. Harris Academy Upper Norwood said it carried out the program to allow its students {#blank#}2{#/blank#} (express) themselves confidently and appropriately. {#blank#}3{#/blank#} we want to make sure of is that they are confident in using standard English. Slang doesn't really give the right impression of the person. Young people going to interviews for their first job need to make a good impression {#blank#}4{#/blank#}employers will have confidence in them.

    Donna Bowater at the Telegraph writes that short forms of words {#blank#}5{#/blank#} (become) popular with the rise of text messages and the social networking website Twitter in the past few years.

    "In addition to {#blank#}6{#/blank#} (give) students the teaching they need to succeed academically, we want them to develop the soft skills {#blank#}7{#/blank#} they will need to compete for jobs and university places," the school was quoted as saying in a statement by the BBC.

    {#blank#}8{#/blank#} the above-mentioned support, South Yorkshire MP Angela Smith said that the policy might cause a risk to dialects (方言) and accents. Some critics argued that slangs provided students with an environment {#blank#}9{#/blank#} they could feel both the history and development of languages.

    The widespread argument is making people wonder {#blank#}10{#/blank#} it is necessary to cut the use of slangs entirely or not. All in all, different opinions of the policy help us have a deeper understanding of the truth that language is always changing with the times.

    You may not know the name John Smith Pemberton, but you must know the name of his{#blank#}1{#/blank#}(invent):Coca-Cola.

To light the addiction, he created his own drink by{#blank#}3{#/blank#} (use) leaves of coca and nuts of kola. He named{#blank#}4{#/blank#}," Pemberton's French Wine Coca". In the same year, the local government passed a ban on alcohol. Pemberton had to change the recipe to remove the alcohol.

    In 1886, Pemberton invited Willis Venable to help him perfect his new recipe. They used carbonated water and finally invented a new drink. It had no alcohol{#blank#}5{#/blank#}could still ease pain and clear the mind. Pemberton decided to sell it{#blank#}6{#/blank#}a drink rather than a medicine. In 1887, Pemberton sold part of the stock of his company to As a Candler,{#blank#}7{#/blank#}later created the Coca-Cola Company.

    Many Americans put away their white clothes on Labor Day {#blank#}1{#/blank#} do not wear them again until the following May.

    One reason for the clothing custom relates to the season. In the United States, the {#blank#}2{#/blank#} (month) between June and September are summer. The weather is usually hot in northeastern cities. Many people there historically wore light-colored clothing in the summertime {#blank#}3{#/blank#} (keep) cool.

    Judith Martin is an expert on manners, {#blank#}4{#/blank#} spoke to Time Magazine about the history of wearing white in summer. She said Americans in the 1800s and early 1900s wore formal clothes all year long. Wearing white clothes in the summertime may make people more {#blank#}5{#/blank#} (comfort). Then, in about the 1930s, wearing white clothes in the summertime became fashionable. That is because some wealthy Americans went on vacation {#blank#}6{#/blank#} weeks or months in the summer. The white clothes then became connected with ease, {#blank#}7{#/blank#} (beautiful) and money. But at the end of summer, they put those white clothes away and {#blank#}8{#/blank#} (return) to their lives in the city, {#blank#}9{#/blank#} (wear) darker and heavier clothes. {#blank#}10{#/blank#} (eventual), not wearing white clothes after Labor Day became a bit of a fashion rule.
