Our ancestors（祖先）made the old saying that friends{#blank#}1{#/blank#}(be) like wine-the older,the better.Because of that, many people think old friends to be{#blank#}2{#/blank#}(important) than new ones.For example,if two pieces of advice are given to solve a problem,one from a new friend and the other from an old friend,people always prefer to choose the latter one,{#blank#}3{#/blank#}the new friend's advice may be better.

    {#blank#}4{#/blank#}(disagree) with the old saying,I believe that new friends are not{#blank#}5{#/blank#}(necessary) worse than old friends. Why?Because the{#blank#}6{#/blank#}(long) of time cannot tell whether your friendship is better or not.

    Once you call someone friend,he must be a person who is{#blank#}7{#/blank#}(rely) and whose interests are in common with{#blank#}8{#/blank#}(you).Maybe a friend's outside look{#blank#}9{#/blank#}(change) all the time,but the inside characters of him and his interests won't change at all.It is just these unchangeable characters and interests that make him a friend to you.{#blank#}10{#/blank#},there is no difference between old friends and new ones on this point.

    Earth Day is an event {#blank#}1{#/blank#} (annual) celebrated on April 22.{#blank#}2{#/blank#} (found) by Senator Gaylord Nelson, an American politician and environmentalist, it was originally aimed at helping the public to know the current situation of pollution and {#blank#}3{#/blank#} (get) people to care about the earth.

    In 1962, Rachel Carson's bestseller “Silent Spring” created an {#blank#}4{#/blank#} (aware) of the dangerous effects of pesticides(农药）. Then, a fire,{#blank#}5{#/blank#}broke out in 1969 on Cleveland's Guyahoga River, revealed the problem of chemical pollution in water. Senator Gaylord Nelson dreamed of{#blank#}6{#/blank#}similar event that would get people to take environmental issues seriously. In 1969, he was inspired by protests against the Vietnam War and came up with the idea for Earth Day.

    In the fall of 1969, Nelson announced it and appealed to the entire country to get involved. Consequently, telegrams, letters and telephone calls {#blank#}7{#/blank#} all over the country poured in. Since 1970, Earth Day celebrations have grown. Later, Nelson{#blank#}8{#/blank#}(award) the Presidential Medal of Freedom because of his work.

    Today, numerous communities celebrate Earth Week, an entire week of{#blank#}9{#/blank#}(activity) focused on the environmental issues. In 2017, the March for Science {#blank#}10{#/blank#}(occur) on Earth Day and was followed by the People's Climate Mobilization on April 29.

    In an English lesson, the teacher noticed Xiao Ming busily {#blank#}1{#/blank#} (type)messages on her cellphone. To the teacher's surprise, Xiao Ming wasn't just texting her friends the{#blank#}2{#/blank#}(late) small talk. She was blogging about what she was learning in the classroom, sharing her opinions{#blank#}3{#/blank#} her classmates.

    The case caused {#blank#}4{#/blank#}heated discussion among teachers and students citywide. Miss Li, another English teacher said, “I am {#blank#}5{#/blank#} (amaze) at how creative the students can be when writing on their blogs. To me it's a great way for students to improve their writing skills while writing about personal feelings and experiences.” But {#blank#}6{#/blank#} made other teachers worried was the blog addiction which may disturb the students' study.

    A supporter and classmate of Xiao Ming said, “We love her blog! We all read it each day and can't wait to see what she writes about next. Many of her {#blank#}7{#/blank#} (suggest) on study really help to encourage us. And we can relax{#blank#}8{#/blank#} (we) while reading her blog.” Another student blogger{#blank#}9{#/blank#} (admit) that he often works late into the night, writing his blog. He said, “Sometimes I don't even have time{#blank#}10{#/blank#}(finish) my homework. I can't help myself. I really have a lot to say.”

    Senior citizens are the first to come to our mind when you think of hearing loss, but in a recent report, hearing professionals worry teenagers will soon outnumber aging adults {#blank#}1{#/blank#} it comes to living with hearing loss.

    The rise in popularity of personal audio devices from iPods to smart phones has had dangerous effect on the ears of those who use them most, teenagers! A research {#blank#}2{#/blank#} (conduct) by the World Health Organization finds that nearly 50% of teens {#blank#}3{#/blank#} (fall) into the habit of exposing themselves to unsafe levels of sound so far.

    A sound is considered unsafe when it goes beyond 85 decibels (分贝). At that level, it takes just 8 hours of listening over your lifetime to cause damage. The louder the sound is, the {#blank#}4{#/blank#} (little) time it takes to cause damage. Because hearing loss is {#blank#}5{#/blank#} (typical) considered a health problem for the elderly, it is difficult to convince already stubborn teenagers that they really are doing damage {#blank#}6{#/blank#} their ears.

    Young adults {#blank#}7{#/blank#} have been exposed to loud noise over a period of time may have some hearing loss symptoms. Their {#blank#}8{#/blank#} (able) to learn is compromised, and they may have difficulty developing social skills.

    In an effort to help teens better protect their hearing, we suggest {#blank#}9{#/blank#} (set) volume limits on personal audio devices. {#blank#}10{#/blank#} is also good to limit the amount of time exposed to noise and to take listening breaks to give the ears a rest.

Emma was on her way home when she heard a sudden scream. Looking around, she saw a little boy on the sidewalk gasping(急喘) for air, his {#blank#}1{#/blank#}(frighten) mother begging for help. Emma rushed to the boy, {#blank#}2{#/blank#} face had turned purple. "What's wrong?" "A candy! In his throat!" It was lucky that Emma had learned how {#blank#}3{#/blank#}(perform) the Heimlich maneuver(海姆利克急救法) at school. She acted quickly. Soon, the boy coughed up a piece of candy and began breathing again. He {#blank#}4{#/blank#}(save) in time.
