Although most people believe that formal schooling is required for scientific success, a college degree is not always necessary. {#blank#}1{#/blank#}excellent example of a man who won fame as a scientist {#blank#}2{#/blank#}academic(学术的) training is Vincent J. Schaefer. His formal education ended {#blank#}3{#/blank#} two years of high school when he had to go to work in an untrained job at General Electric. Because {#blank#}4{#/blank#} his inventive mind and his skill as a model maker, he was soon allowed to try his own experiments in the company laboratory. His natural {#blank#}5{#/blank#}(curious) made him wonder about clouds. He developed, after many tries, a method of making clouds rain {#blank#}6{#/blank#}they would not normally do so. This method, {#blank#}7{#/blank#}(call) seeding, has been very {#blank#}8{#/blank#}(help) to farmers, and {#blank#}9{#/blank#}made him win much fame.

    Schaefer believes that for people{#blank#}10{#/blank#}, most of all, are interested in the world and everything in it, a college degree is unnecessary.

    I happened to be walking along the city street when I set my sight on a bakery, where a man with a tall hat is making{#blank#}1{#/blank#}cake, so I stopped{#blank#}2{#/blank#}(watch) how it was made. After watching it for several times for the next few{#blank#}3{#/blank#} (day), I decided to make one myself. With everything I needed{#blank#}4{#/blank#} (prepare), I began to carry out the whole process{#blank#}5{#/blank#} the help of the instruction book without {#blank#}6{#/blank#}(interrupt). After three times of failure, I finally made it and couldn't be more{#blank#}7{#/blank#}(excite)

    From this experience{#blank#}8{#/blank#}I have learnt is that as long as you try, God will always be on your side; on the contrary, if you just do things halfway, only {#blank#}9{#/blank#}(leave) the rest unfinished, the regrets will{#blank#}10{#/blank#}(definite) come after you.

    A boy trembled in the cold winter, wrapping his arms wound {#blank#}1{#/blank#}(he) on a bus stop bench. He wasn't wearing warm clothes and the temperature was -10℃.{#blank#}2{#/blank#} a heartbreaking scene it was! But the good deeds of the ordinary people {#blank#}3{#/blank#}witnessed the 11-year-old Johannes were both joyous and inspiring. A woman, {#blank#}4{#/blank#} (sit) next to the boy, discovered he was on a school trip and was told to meet his teacher at the bus stop. She {#blank#}5{#/blank#} (selfless) covered his shoulders with her own coat.{#blank#}6{#/blank#} (late), another woman at first gave him her scarf, and then wrapped him in her large jacket. Throughout the day, more and more people offered Johannes their gloves and even the coats off their backs.

    Actually, it was a {#blank#}7{#/blank#}(hide) camera experiment by Norwegian charity SOS Children's Village as part of their winter campaign to collect {#blank#}8{#/blank#} (donate) to help Syrian children get through the winter. Synne Ronning, the information head of the organization, also {#blank#}9{#/blank#}（note） that the child was a volunteer who was never {#blank#}10{#/blank#}any danger during the filming.

    I grew up in one of the poorest communities on the south side of Atlanta, US and was raised by a single mother who didn't finish 3rd grade. Not many people expected much of me, so I had to expect something of {#blank#}1{#/blank#}.

    On my 13th birthday, I bought a poster of Harvard and put it up in my room. Being at Harvard was {#blank#}2{#/blank#} I dreamt about all the time though many people thought it was far {#blank#}3{#/blank#} my reach. I would bum the midnight oil,{#blank#}4{#/blank#} (bury) in piles of books. I'd begin my day by asking myself these two questions, "What do I want in my life?" and "Are the things I am doing today going to get me closer to that life?"

    {#blank#}5{#/blank#} (remind) myself of my goal each made it easy to say no to the same choices I saw my peers making, because those paths wouldn't have taken me closer to my goal. Asking myself those questions gave me the courage and energy to study just one more hour on my SATs when my friends were asleep; and it gave me the determination to submit（提交）just one more scholarship {#blank#}6{#/blank#} (apply) when 180 others had already turned me down.

    On March 31st, 2011, {#blank#}7{#/blank#} email arrived from Harvard. The first word was "Congratulations!" A

    month later, Harvard invited me to visit the campus {#blank#}8{#/blank#} for the first time I got to see inside Sanders Theater, tour Widener Library and eat dinner in Annenberg Hall. I couldn't wait to start my {#blank#}9{#/blank#} (explore) here.

    Who you are today is the result of the decisions that {#blank#}10{#/blank#} (make) earlier, and who you will be tomorrow will be the result of the choices you make today. Who do you want to be tomorrow?

    The Chinese People's Liberation Army Navy turned 70 on April 23, 2019. It is a time for reflecting on its beginning and how over the past seven decades it has overcome so many difficulties to grow {#blank#}1{#/blank#} a modem naval force.

    As a major Pacific country {#blank#}2{#/blank#} has more than 18, 000 kilometers of coastline, China needs a powerful naval force that can timely respond to challenges and risks. The PLA Navy is increasingly being looked upon as an essential force {#blank#}3{#/blank#} (defend) the country's interests and protect its nationals' personal safety and {#blank#}4{#/blank#} (possession) overseas.

    Thus, the calls for China to build a blue-sea navy have become stronger, {#blank#}5{#/blank#} the PLA Navy has apparently accelerated its modernization steps trying to increase its battle abilities and readiness. Not to mention that the navy also has the duty to more {#blank#}6{#/blank#} (effective) respond to challenges to the country maritime (海上的) interests and territorial integrity (领土完整).

    However, as part of China's defense forces, the PLA Navy is a force for {#blank#}7{#/blank#} (peace) purposes, The PLA Navy has also actively participated in international humanitarian missions (使命) and {#blank#}8{#/blank#} (conduct) various exchanges with naval forces from other countries to build understanding and {#blank#}9{#/blank#} (strength) trust.

    So we have reason to believe that the PLA Navy {#blank#}10{#/blank#} (contribute) better to world peace and development.

    Maryland's Cecil County is home to many interesting parks. However, {#blank#}1{#/blank#}is more mysterious and disturbing than the Perryville Community Park {#blank#}2{#/blank#}around 100 trees are marked by strange messages left by the mentally disordered patients in a hospital decades ago.

    Before becoming a public park, the land {#blank#}3{#/blank#} (own) by the nearby hospital, and some of its former patients carved their disturbed thoughts into the trees. Over time, the words together {#blank#}4{#/blank#}the drawings carved into the tree bark have grown larger, {#blank#}5{#/blank#}(draw) the attention of curious passers-by. {#blank#}6{#/blank#}(interesting), even though the mark trees of Perryville Community Park have become quite popular among {#blank#}7{#/blank#}(tour), and even gotten their own Wikipedia entry, few residents of the Maryland town know about them and their history.

    Of all the phrases carved into the trees, the {#blank#}8{#/blank#}(strange) ones are "Christ said to police there was no Second World War," and "October 18, 1960 The City of Baltimore has not believed yet — Saint Callender — police. "

    The years carved into the trees date back to 1911, but the most {#blank#}9{#/blank#}.(mention) year is 1958, along with the name "Nelson Jonchou", which many believe belonged to one of the soldiers who {#blank#}10{#/blank#}(be) once admitted to the hospital.
