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.

    In 1969, Armstrong {#blank#}1{#/blank#}(successful) set foot on the Moon. This was {#blank#}2{#/blank#} first time anyone had walked on the surface of another world. More astronauts（宇航员）reached the Moon later, but nobody {#blank#}3{#/blank#}(visit) it since 1972. Do you think it's time we went back?

    {#blank#}4{#/blank#}(explore) of the Moon did continue after the astronauts left, but by robots instead {#blank#}5{#/blank#} people. Satellites have helped us learn more about our neighbour and shown that there {#blank#}6{#/blank#}(be) even more exploring to do, but astronauts would be needed!

    The problem is that sending humans to the Moon is very expensive. Even with all the new technology since Armstrong's time, it would cost so much for people {#blank#}7{#/blank#}(return) to the Moon.

    ESA (European Space Agency) wants to change that. ESA's idea isn't just to make the spaceships {#blank#}8{#/blank#}(they), but also to work with businesses here on Earth. ESA also wants to help businesses on Earth develop tools and technology {#blank#}9{#/blank#} will allow people to live on the Moon. If we can use resources（资源）on the Moon, then journeys there will be much {#blank#}10{#/blank#}(cheap). For example, what if we could get to water hidden deep within Moon rocks?

    I have even wondered if money buys happiness. It seems that money will allow me to buy the things {#blank#}1{#/blank#}make me happy. But one day I sat down and made a list of the things I wanted{#blank#}2{#/blank#}(do) in my life. I realized I'd never put much thought into it. I'd written down these things —like taking a photo on the mountain and staying at a hotel in Dubai, but I didn't really plan to do it, {#blank#}3{#/blank#} (simple) because I didn't have the time.

    My life consisted {#blank#}4{#/blank#} heading to the office, running on the road, working some more …It didn't matter if my salary doubled; the life would stay {#blank#}5{#/blank#}same. Sure I'd probably drive a {#blank#}6{#/blank#} (nice) car, move into a bigger place, and have a bigger TV than my friends, but that wasn't helping me realize any of my goals. Six months after{#blank#}7{#/blank#} (create) that list, my belief has changed. I'd keep working on my list, for {#blank#}8{#/blank#} (experience) were much more important than any of the material items. It's not hard to create opportunity for {#blank#}9{#/blank#} (you). All it {#blank#}10{#/blank#} (take) is a little creative thinking.

    25 people were killed and 50 injured on Wednesday in a train accident in Cairo, which surprised local people. According to the BBC, Prime Minister Mostafa Madbouli visited the scene and he said {#blank#}1{#/blank#} cause was not yet known, but Egypt's police were conducting an investigation (进行调查) {#blank#}2{#/blank#} (find) the reason of the accident. Egypt had one of the {#blank#}3{#/blank#} (old) and largest rail networks, and crashes and other accidents were common.

    While bottled water is convenient, it is also really bad for the environment. Not only does it create rubbish, but it also uses more resources because it {#blank#}1{#/blank#} (ship) to the shore. To be more eco-friendly, make it a habit {#blank#}2{#/blank#} (carry) a reusable water bottle with you everywhere so that you can drink water on the go. Plastic bottles are usually the {#blank#}3{#/blank#} (light) and most convenient. You can also find glass water bottles that are a great choice if don't like using plastic.

For much of history, reading was a fairly noisy activity. Today, however, the majority of us bottle the words in our heads as if {#blank#}1{#/blank#}(sit) in a library.

Recent studies provide ample evidence {#blank#}2{#/blank#} the ancient art of reading aloud has a number of benefits, from helping improve our memories {#blank#}3{#/blank#}strengthening emotional bonds between people.

According to a research on the impacts of reading on memory, people consistently remember words and texts {#blank#}4{#/blank#}(well) if reading them aloud than if reading them silently. This phenomenon has been named the "production effect", which means that producing {#blank#}5{#/blank#}(write) words-namely, reading them out loud-improves our memory of them. Even just silently mouthing the words makes {#blank#}6{#/blank#} more memorable.

One reason why people remember the spoken words better is that it gives us {#blank#}7{#/blank#} additional basis for memory. We are {#blank#}8{#/blank#}(general) better at recalling events that require active involvement. For instance, producing a word in {#blank#}9{#/blank#}(respond) to a question makes it easier to remember.

In time when our interactions with others and the large amount of information we take in {#blank#}10{#/blank#}(be) all too transient (转瞬即逝的) , perhaps it is worth making bit more time for reading out loud.
