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.

    One day a young man was walking along the road {#blank#}1{#/blank#} he heard a cry. It seemed to be coming from underneath a bridge. As he approached the bridge, the sound got {#blank#}2{#/blank#} (loud) and then he saw {#blank#}3{#/blank#} pitiful sight. There, lying in the muddy riverbed was a little dog about two months old, {#blank#}4{#/blank#} front legs were tightly tied with ropes. It had wounds on its head and {#blank#}5{#/blank#} (cover) with mud.

    The young man wanted to help the dog, {#blank#}6{#/blank#} as he approached, the dog started to bark. The young man did not give up. He sat down and started {#blank#}7{#/blank#} (gentle) talking to the dog. It took a long time but eventually the dog {#blank#}8{#/blank#} (stop) barking and the man was able to touch it. The young man carried the dog home, cared for its wounds, and gave it food and water. Even with all of this, the dog was still {#blank#}9{#/blank#} (friend) every time the young man approached. But the young man did not give up. Weeks went by and the man continued attending to the dog. Then one day, as the young man approached, the dog wagged its tail.

    It was consistent love and kindness {#blank#}10{#/blank#} won a lifelong friendship of loyalty.

    When Jennifer Lawrence tripped on her way to accept her best actress Oscar one year, her pink princess-like Dior dress {#blank#}1{#/blank#} (capture) in all its glory. The unscripted moment became hot topic throughout social media.

    That bonus air-time for a single dress at one of the world's global events is priceless for the likes of Dior, one of the {#blank#}2{#/blank#} (influential) fashion houses in the luxury marketplace.

    Success on the red carpet can earn exposure and profits for luxury brands for years {#blank#}3{#/blank#} (come). The red carpet, which will be televised live before Academy Award ceremony, presents a great opportunity for a designer to reach an audience that expands {#blank#}4{#/blank#} the fashion setting. The Lawrence dress received about 40 million mentions on various social media.

    One way of estimating the monetary benefits of having a standout dress on the red carpet is to compare how much a brand would otherwise spend on commercial advertising during the same time. {#blank#}5{#/blank#} Lawrence had only 75 seconds of solo camera time for her Oscar acceptance speech, Dior had to pay more than $4 million for a commercial spot of the same duration on similar occasions. And this didn't include the time {#blank#}6{#/blank#} (devote) to Lawrence and her dress on the pre-show televised red carpet. Lawrence, 23, had an advertising contract with Dior. {#blank#}7{#/blank#} the group's deal with Lawrence affected its sales was clearly stated in its annual financial report. That year, the group clothing section's profits {#blank#}8{#/blank#} (total)165 million euros, up 26 percent from the previous year.

    Heston, the founder of a publicity firm, {#blank#}9{#/blank#} success stories include introducing Jimmy Choo shoes and designer Saab to Hollywood, believes that the Oscar red carpet is today dominated by established luxury brands. Finding it much more difficult to compete with big brand names to dress super stars on big events, many young designers turn to {#blank#}10{#/blank#} (bet) on promising rising stars, expecting an overnight success if the young stars rise to sudden fame.
