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 Sir or Madam,

    I've learned that an art exhibition is {#blank#}1{#/blank#}(hold) and that you're collecting suggestions on its location. I'm writing this letter to share{#blank#}2{#/blank#} you my opinions.

    In my opinion,{#blank#}3{#/blank#} is more advisable to hold the art exhibition in Shanghai Museum than in community libraries. My reasons are as follows.

    On one hand, it is {#blank#}4{#/blank#}(convenient) for people to get to Shanghai Museum{#blank#}5{#/blank#}is located in the center of the city. Besides, the museum is much larger than commuity libraries, which {#blank#}6{#/blank#}(provide)visitors with more comfortable environment for{#blank#}7{#/blank#}(appreciate) art.

    On the other hand, as a well-known museum, Shanghai Museum is more professional and {#blank#}8{#/blank#}(experience)in holding art exhibitions. Its professional security guards and advanced facilities can better protect those famous {#blank#}9{#/blank#}(paint)from being damaged {#blank#}10{#/blank#}stolen.

    Therefore, I suggest the exhibition should be held in Shanghai Museum.

    Kids would love to have more money in their pockets. With the money that {#blank#}1{#/blank#}(make) by themselves they can buy the things they want. Actually, making money when you are a kid is much{#blank#}2{#/blank#}(easy) than you think. Here is a great method of making money for you, if you are a kid. It's dog walking.

    Don't try to do dog walking as a business if you are not{#blank#}3{#/blank#}(comfort) with dogs. However, if you love dogs, this can be a good {#blank#}4{#/blank#}(choose).

    Usually your customers are in the neighborhood. Ask dog owner {#blank#}5{#/blank#}(tell) you as much as possible{#blank#}6{#/blank#} their dogs and their habits. It's very important that you keep friendly with the dogs{#blank#}7{#/blank#}(bring) a treat to the dogs can help develop a friendship with them.

    You can charge 5 dollars {#blank#}8{#/blank#}a walk lasts 30 minutes. If a dog's owner wants you to walk{#blank#}9{#/blank#}(he) dog for an hour, you can charge 10 dollars or even 15 dollars.

    The only disadvantage of this method is that you have to deal with dog waste. Be sure to take{#blank#}10{#/blank#} bag and clean up after those dogs.

    Athens, the capital of Greece{#blank#}11{#/blank#}(know)as the birthplace of{#blank#}12{#/blank#}(west) civilization. Two thousand four hundred years ago, it was the world's most {#blank#}13{#/blank#}(power)city{#blank#}14{#/blank#} (build) such as the Parthenon on the Acropolis Hill were built during this period. Greece's best writers lived in ancient Athens. Their work has influenced other writers ever {#blank#}15{#/blank#}

    We use flowers as messengers, to say something we might have trouble saying {#blank#}1{#/blank#} (direct) by ourselves. Over time flowers have come to symbolize the most powerful human {#blank#}2{#/blank#} (experience): beauty, love, hope, and rebirth. Sweet flowers alone can say what one fears expressing. We've listed some of the most famous flowers {#blank#}3{#/blank#} have a special significance.

    In Mao Zedong's poem Ode to Plum Blossom（《咏梅》）, the plum blossom was used {#blank#}4{#/blank#} (praise) great soldiers who sacrificed {#blank#}5{#/blank#} (they) lives for a better life for Chinese people.

    {#blank#}6{#/blank#} great Chinese poet Li Bai from the Tang Dynasty once compared Yang Yuhuan's beautiful face {#blank#}7{#/blank#} blooming peonies（牡丹）. Flowering in May, peonie's large petals and strong colors are linked to prosperity and {#blank#}8{#/blank#} (rich) in traditional Chinese culture.

    The orchid（兰花）is well known for its delicate smell. Beautiful articles and poems {#blank#}9{#/blank#} (call) “lanzhang” by Chinese people in ancient times.

    Roses, of course, have the most colorful meaning among all the flowers. Red roses, to this day, mean “I love you.” A red rose, rather than yellow roses, acts as the traditional romantic gift {#blank#}10{#/blank#} (give) to your love on Valentine's Day. Sending yellow roses can be risky, as they represent either friendship or envy.

    When we talked about NBA, many people will think of Yao Ming. There is no doubt that Yao Ming is a Chinese hero. On October 16, 2013, Yao Ming announced he{#blank#}1{#/blank#}open the NBA Yao School. This was really{#blank#}2{#/blank#}（excite）news!

    {#blank#}3{#/blank#}（look）at the name of the school, many people would think that the school is going to train NBA{#blank#}4{#/blank#}（talent）. But the truth is not like {#blank#}5{#/blank#} they expected. The NBA Yao School provides after-school basketball training and health programs. Its students include boys and girls over 16 years old {#blank#}6{#/blank#} are very good at playing basketball. The school aims {#blank#}7{#/blank#}（teach） the importance of teamwork, leadership(领导素养) and communication in a fun basketball environment.

    Yao is quite glad to be a part of the school, because it has always been his dream to{#blank#}8{#/blank#}（positive）influence young people's life through sports.

    Now, basketball fans in China are looking forward to getting basketball training, and the NBA Yao School is a great choice. In the school, students have chances to meet NBA stars. The stars can offer {#blank#}9{#/blank#}（suggest）on how{#blank#}10{#/blank#}（play） basketball well.

    Are you sometimes a little tired {#blank#}1{#/blank#} sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time——about eight hours after {#blank#}2{#/blank#} (wake) up——your body temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits in experiments in {#blank#}3{#/blank#} there was no night or day. The people in these experiments almost always {#blank#}4{#/blank#} (follow) a similar sleeping pattern. They slept for one long period and then for one short period about eight hours {#blank#}5{#/blank#}.

    In many parts of the world, people take naps {#blank#}6{#/blank#} the middle of the day. This is {#blank#}7{#/blank#} (especial) true in warmer climates, where the heat makes it difficult {#blank#}8{#/blank#} (work) in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A {#blank#}9{#/blank#} (day) nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer less from {#blank#}10{#/blank#} (problem) such as heart disease.
