—Yes, she doesn't even have enough {#blank#}1{#/blank#} to walk upstairs.

    Mr. James owns a company. He put an advertisement {#blank#}1{#/blank#}a newspaper for a boy to work in his office. Out of nearly fifty people {#blank#}2{#/blank#}came to apply, the man selected one and dismissed {#blank#}3{#/blank#}others.

    “I would like to know,” said a friend, “the reason you preferred that boy, who brought neither a single letter, {#blank#}4{#/blank#}a single recommendation.”

    “You are wrong,” said the gentlemen. “He had many. He wiped his feet at the door and closed the door behind him, {#blank#}5{#/blank#}(mean) that he was careful. He gave his seat immediately to an old man, showing that he was kind and {#blank#}6{#/blank#}(thought). He took off his cap when he came in and answered my questions quickly, showing that he was a polite gentleman. Everyone else stepped over the book that I {#blank#}7{#/blank#}(put) on the floor purposely. He picked {#blank#}8{#/blank#}up and placed it on the table, and he waited quietly for his turn instead of pushing and crowding. When I talked to him, I {#blank#}9{#/blank#}(notice) his tidy clothing, his neatly brushed hair, and his clean finger mails. Can't you see that these are excellent recommendations? I considered them to be more significant than {#blank#}10{#/blank#}(letter).”

    Hearing the words, the friend nodded in agreement.

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

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

    But now frogs{#blank#}4{#/blank#} (get) fewer and fewer. This is because they are killed and put{#blank#}5{#/blank#} the table as a delicious dish by their chief enemy, human beings. It is a shameless and cruel act, isn't it?

    The cause that is{#blank#}6{#/blank#} (responsibility) for the rapid reduction of frogs is that farmers use insect killer to kill pests and frogs get killed as a result of drinking poisoned water while{#blank#}7{#/blank#} (eat) poison-killed insects.

    Something must be done as soon as possible {#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 them.

    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.

    Sudan is the only male northern white rhino (犀牛) left in the world. That {#blank#}1{#/blank#} (mean) Sudan, 42, is the last hope for avoiding extinction. {#blank#}2{#/blank#}(protect) him, officials have placed him under 24-hour armed guard at the OI Pejeta Conservancy in central Kenya. Sudan lives there {#blank#}3{#/blank#} two female northern white rhinos, Fatu and Najin.

    Northern white rhinos, {#blank#}4{#/blank#} can weigh up to 5,000 pounds, were once plentiful across northern and central Africa. {#blank#}5{#/blank#} (hunter) have killed thousands of rhinos because of {#blank#}6{#/blank#} high demand for the animals，horns (角). Rhino horns, believed to have medical effects, are used in {#blank#}7{#/blank#} (tradition) Asian medicines. More than 1,000 rhinos {#blank#}8{#/blank#} (kill) in 2014 in South Africa alone and fifty-four rhinos in Kenya, which has a much {#blank#}9{#/blank#} (small) population.

    Sudan, Fatu, and Najin have had their horns {#blank#}10{#/blank#} (remove) so that they will not be hunted. People hope Sudan and one of the females will be able to have a baby. Sudan is very old, but scientists will not give up hope.
