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.

    Dear helpful Hannah,

    I've got a problem with my husband, Sam. He bought a smart phone a couple of months ago and he took it on our recent ski vacation to Colorado, it was a great trip except for one problem. He has a constant urge {#blank#}1{#/blank#} for next messages; he checks his phone every five minutes! He's so addicted to it that he just can't stand the idea{#blank#}2{#/blank#} there may be an important text. He can't help checking even at inappropriate times like when we are eating in a restaurant and I am talking to him! He behaves {#blank#}3{#/blank#} any small amount of boredom can make him feel the need to check his phone even when he know he shouldn't. The temptation to see {#blank#}4{#/blank#} is connecting him is just too great. When I ask him to put down the phone and stop {#blank#}5{#/blank#}  (ignore) me, he say, “In a minute.” but still checks to see if {#blank#}6{#/blank#} has posted something new on the Internet. Our life {#blank#}7{#/blank#}  (interrupted). If we go somewhere and I ask him to have the phone at home, he suffers from withdrawal symptom. May this dependency on his smart phone has become more than an everyday problem.

    I recently read an article about “nomophobia,”{#blank#}8{#/blank#} is a real illness people can't suffer from the fear of being without your phone! I am worried that Sam maybe suffering from this illness because he feels anxious if he doesn't have his phone with him, even for a short time.

Who would have thought that little devices like these could have brought so much trouble!

    During the teenage years, many young people can at times be difficult to talk to. They often seem {#blank#}1{#/blank#} (dislike) being questioned. They may be {#blank#}2{#/blank#} (willing) to talk about their work in school. This is a normal {#blank#}3{#/blank#} (develop) at this age, though it can be very hard for parents to understand. It is part of {#blank#}4{#/blank#} (become) independent. They try to be adult while they are still growing up. Young people are usually more willing to talk if they believe that questions {#blank#}5{#/blank#} (ask) out of real interest and not because people are trying to check up on them.

    Parents should do their best to talk to their sons and daughters {#blank#}6{#/blank#} their schoolwork and future plan {#blank#}7{#/blank#} should not push them to talk if they don't want to. As they try to be adult, {#blank#}8{#/blank#} (teenager) may experiment with drugs, alcohol or smoking, so parents should {#blank#}9{#/blank#} (careful) watch for any sign of unusual behavior {#blank#}10{#/blank#} may be connected with these and get help if necessary.

    There are about 100 million middle-aged women dancing in parks and on squares in China, and Deborah Roundy, {#blank#}1{#/blank#} U.S retired school teacher, is one of them. Mrs. Roundy is the only foreigner on the Shanghai dance team at Tongji University, where she is {#blank#}2{#/blank#}(current) teaching English.

    Mrs. Roundy ran upon a dozen or so middle-aged women dancing {#blank#}3{#/blank#} the tunes of Chinese songs in 2012. At the time, she didn't feel used to the new environment and wanted to have some fun in her life. She {#blank#}4{#/blank#}(invite) to join the dancing team.

    At first, Mrs. Roundy communicated with her teammates by {#blank#}5{#/blank#}(exchange) notes to help translate for her. Now she uses a translation app on her iPad.

    {#blank#}6{#/blank#} the Chinese language is not the most difficult thing for her, mastering Chinese dance is. Mrs. Roundy used to do ballet. She said {#blank#}7{#/blank#}(dance) in the U.S. always dance facing the audience. But in China, they change directions all the time, and it was very {#blank#}8{#/blank#}(confuse) for her at first.

    They have developed good personal relations. Mrs. Roundy says they also go out to eat and on field trips together, which are {#blank#}9{#/blank#}(forget) experiences for her.

    Square dancing opens a window for her {#blank#}10{#/blank#}(understand) China, Mrs. Roundy said: Besides dancing, she and her husband have been active in community life, teaching English, and helping elderly neighbors.

    Flying cars may soon become a {#blank#}1{#/blank#} (real). The rideshare service Uber has asked {#blank#}2{#/blank#} expert from NASA, the American space agency, {#blank#}3{#/blank#} (help) the company develop cars that can fly.

    Uber plans to use flying vehicles {#blank#}4{#/blank#} the future to avoid traffic in and around cities. The company wants to use small, totally electric aircraft, {#blank#}5{#/blank#} could take off and land like a helicopter on top of parking garages. Uber said its flying vehicles would be much {#blank#}6{#/blank#} (quiet), cost less to operate and produce less pollution than helicopters.

    One person in San Francisco {#blank#}7{#/blank#} (write) on Twitter, "I used to think that flying cars was a ridiculous idea. {#blank#}8{#/blank#} I changed my mind this morning when I sat in a heavy traffic." Another person added from Mumbai, India: "I'm reading about Uber {#blank#}9{#/blank#} (hire) a NASA engineer to build flying cars, while Fm stuck in traffic. There is hope."

    The expert predicts there will be several early models of cars that can't fly {#blank#}10{#/blank#} (they) but with human pilots within one to three years.
