I first met Steve Jobs years ago at a yard pool party. I was {#blank#}1{#/blank#} excited and embarrassed by the chance to meet him in person that I could hardly whisper my name when we {#blank#}2{#/blank#}(introduce). I watched as he swam in the pool with his son, like a regular guy, a good dad {#blank#}3{#/blank#}(have) fun with his kids.

    The second time I met him was when our children started going to school together. He was sitting in the classroom while {#blank#}4{#/blank#}rest of us were pretending that having Steve Jobs in the room was {#blank#}5{#/blank#} (total) normal. It was one Halloween when I realized he actually knew my name, {#blank#}6{#/blank#} made me a little surprised. {#blank#}7{#/blank#}(dress) like a monster, he was decorating a scary house with his wife. As I walked by with my son, Steve smiled and said, “Hi, Lisen”, My son thought I was the {#blank#}8{#/blank#}(cool)mom in town when he realized Steve Jobs knew me.

    {#blank#}9{#/blank#} then on, when I saw him holding his meetings in our neighborhood, I didn't hesitate to smile and say hi. Steve always {#blank#}10{#/blank#} (return) the greetings, proving that while he may have been a genius, he was also a good neighbor.

    Is there such a thing as being "over-protective"?

    I can honestly say that my answer to that question {#blank#}1{#/blank#} (change) dramatically（戏剧性地） since I became a parent.

    Before the birth of my daughter. I taught at {#blank#}2{#/blank#} private school often viewing my students as over-protected, worrying {#blank#}3{#/blank#} would happen when they went on to middle schools.

    Some did fine, and some did not. Some needed constant pats on the back, words of {#blank#}4{#/blank#} (encourage) and extra support, which I {#blank#}5{#/blank#} (happy) gave. Others were content on their own, needing little or no interaction（互动）with their teacher. {#blank#}6{#/blank#} for the most part, graduates would go on for higher schooling.

    I'd always supposed their parents were over-protective, for they were the ones that still walked their {#blank#}7{#/blank#} (five) graders into the classroom and met them at the school gate.

    Admittedly, I laughed at those parents, {#blank#}8{#/blank#} (think) their children would never learn to be {#blank#}9{#/blank#} (independence) if they didn't let go just a little. Then I had my own daughter. The moment I looked at her little face, I {#blank#}10{#/blank#} (know) I'd do everything in my power to protect her and make sure she always felt safe!

    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.

    When I was a kid, Mom used to cook food for us. One night after {#blank#}1{#/blank#} (spend) a long hard day at work, Mom placed a plate of bread jam and {#blank#}2{#/blank#} (extreme) burnt toast（烤面包） in front of my dad, I was waiting {#blank#}3{#/blank#} (see) if he noticed it. However, while eating his toast. Dad just asked me {#blank#}4{#/blank#} my day was at school. I don't remember what I told him that night,{#blank#}5{#/blank#} I do remember I heard Mom apologizing to Dad for burning the toast. I'll never forget what Dad said, “Honey, I love burnt toast.”

    Later that night, I {#blank#}6{#/blank#} (go) to kiss Daddy good night and asked him if he really liked his toast burned. He gave me {#blank#}7{#/blank#} big hug and said, “Your mamma put in a long hard day at work today, really {#blank#}8{#/blank#} (tire). Besides, a burnt toast never hurts but cold words do!”

    What I've learned over the years {#blank#}9{#/blank#} (be) that learning to accept each other's faults is one of the most important {#blank#}10{#/blank#} (key) to creating a healthy, growing and lasting relationship.

    Dogs were first raised at home at least 150 centuries ago. Since then, the dog {#blank#}1{#/blank#} (be) humans' best friend. Now, they have another job—to assist doctors to diagnose（诊断）cancer.

    After a long-standing research of smell, a Finnish professor has said that certain {#blank#}2{#/blank#} (type) of cancer are able to be detected by their smell, making it possible to train cancer-sniffing dogs {#blank#}3{#/blank#} (help) diagnose the disease.

    A professor, Jouko Vepsalainen from the University of Eastern Finland in Kuopio, has focused {#blank#}4{#/blank#} nitrogen compounds（氮化合物）. The compounds increase {#blank#}5{#/blank#} (great) when cancer cells grow in an uncontrollable way, {#blank#}6{#/blank#} (allow) them to be detected, the Finnish newspaper Karjalainen reported. That's where the dog, man's best friend, may step in with their keen sense of smell.

    According to the news agency, researchers in Finland have tried to train dogs to do the job, but {#blank#}7{#/blank#} will take a dog months, even years, to tell the {#blank#}8{#/blank#} (different) between sick and healthy people. “Anyone {#blank#}9{#/blank#} knows how difficult early cancer detection is {#blank#}10{#/blank#} (understand) what an opportunity this is,” associate professor Anna Hielm-Bjorkman of the University of Helsinki told the Finnish media.
