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.

    You might want to think twice before purchasing{#blank#}1{#/blank#}(conventional) grown strawberries or spinach(菠菜). According to a new report from the Environmental Working Group(EWG), these foods are the most likely{#blank#}2{#/blank#}(pollute) with the pesticide.

    Even low levels of pesticide exposure can be harmful to infants, babies and young children,{#blank#}3{#/blank#}parents and caregivers should take measures to lower children's exposures{#blank#}4{#/blank#}pesticides while still{#blank#}5{#/blank#}(feed) them diets rich in healthy fruits and vegetables.

    Just last year, the red berry knocked apples and{#blank#}6{#/blank#}(hold) the title of the most polluted. The pesticide increased in strawberries because of out-of-season demand. The most polluted strawberry had traces of 20{#blank#}7{#/blank#}(vary) pesticides.

    Also moving up on{#blank#}8{#/blank#}list this year is spinach. Spinach jumps from the{#blank#}9{#/blank#}(eight) to the second most polluted product. The study finds spinach samples contain more pesticides by weight than all other produce{#blank#}10{#/blank#}(test). In high doses, it can cause damage to the nervous system.

    People often have trouble {#blank#}1{#/blank#} (get) used to a new culture because they need a long time to adapt to it. They are usually curious {#blank#}2{#/blank#} they first arrive in a foreign country and sometimes they may get confused about what to do. However, if they stay for {#blank#}3{#/blank#} long time, they may start to feel different {#blank#}4{#/blank#} (stage) of culture shock. They can feel lonely or sad because they can't deal with the local people. How {#blank#}5{#/blank#} (quick) people get used to culture differences may depend on the way they {#blank#}6{#/blank#} (learn). That's a problem if they can't speak the language. So the first important thing is to learn to speak the local language. On {#blank#}7{#/blank#} other hand, some can study the situation and make good guesses about the culture. When they finally begin {#blank#}8{#/blank#} (understand) some of the language and make some new {#blank#}9{#/blank#} (friend), they will gradually enjoy themselves and feel {#blank#}10{#/blank#} (comfort). Then they can live an easy life in a completely new culture.
