Should naps(小睡) actually {#blank#}1{#/blank#} (take) during the day? Well, we certainly know from {#blank#}2{#/blank#} (evident) in the sleep center and that of many other scientists that naps can give you benefits for both your brain {#blank#}3{#/blank#} your body. But naps can actually be {#blank#}4{#/blank#} double-edged sword because while we're awake during the day, we're building up sleepiness or sleep pressure. So when you try to fall asleep at night, you'll fall asleep quickly and then you'll stay asleep. And when we sleep, we actually release that sleepiness so that we wake up the next morning feeling {#blank#}5{#/blank#} (refresh).

    So if you take a nap during the day, especially if you take it too late in the afternoon, you will actually release some of that sleepiness and it will make it much {#blank#}6{#/blank#} (hard) to fall asleep and stay asleep soundly throughout the night. So the advice would be if you don't struggle with your sleep and you can nap{#blank#}7{#/blank#} (regular), then naps are just fine.

    But if you do find it difficult {#blank#}8{#/blank#} (fall) asleep or stay asleep at night, then you should avoid naps and try to build up that healthy sleepiness in the evening.

    The ideal nap depends on {#blank#}9{#/blank#} you want from that nap. Different stages of sleep actually give you different types of brain and body  {#blank#}10{#/blank#} (benefit).

    Since 1949 when the People's Republic of China {#blank#}1{#/blank#}(establish), and especially since 1978, China's transformation from a traditional {#blank#}2{#/blank#}（agriculture）society to a modern industrial society has been greatly accelarated by a rapid industrial restructuring. China's industrial structure developed according to the objective of industrialization, {#blank#}3{#/blank#} aimed at the proportion(比例)of agriculture declining ceaselessly, and the proportion of the industrial and service sector increasing continually. {#blank#}4{#/blank#}(current), the industrial goods produced in China all range from capital goods to consumption goods.

    China's factory outputs extend from textiles (纺织业) to railway, planes and computers. China is the largest producer of inexpensive cotton textiles in the world and exports large {#blank#}5{#/blank#}(quantity) of textiles and clothes. Food processing is very important, and much farm produce is exported. Other industrial products {#blank#}6{#/blank#}(include)television sets, bicycles, cars, trucks and washing machines are expanding in the world.

    China has become {#blank#}7{#/blank#} industrialized country to some extent. The auto and the housing industry, in the process of industrialization have developed by leaps and bounds. The most important export products are machinery and electric equipment,{#blank#}8{#/blank#} the most important import products are raw materials. In recent years, China's industry{#blank#}9{#/blank#}(compete) internationally, and as a result, the {#blank#}10{#/blank#}(develop)of the country's industry is increasingly influenced by international economic environments.

    As you know, science plays {#blank#}1{#/blank#}important role in our education. Do you want to keep up with the latest research and discoveries in science? There are many good websites {#blank#}2{#/blank#} you can check out the latest in the science world.

    One great site is Science News for Kids. This site reports science news {#blank#}3{#/blank#} (cover) a wide range of subjects. The articles are intended {#blank#}4{#/blank#} younger readers,{#blank#}5{#/blank#} adults will find this site suitable for them as well. Another wonderful site, one that I check out every day, {#blank#}6{#/blank#} (call) Science Daily. The site is {#blank#}7{#/blank#} (constant) updated with news, often about exciting {#blank#}8{#/blank#} (finding) that change how we view the world.

These sites post the latest stories and also keep all the past articles they {#blank#}9{#/blank#} (post) earlier. That way you can find just about anything that {#blank#}10{#/blank#} (be) related to the science fields your are interested in.

Invisible People

If you have the time, check out an amazing YouTube channel that I recently found {#blank#}1{#/blank#} (call) "invisible people". It's a channel with {#blank#}2{#/blank#} (hundred) of interviews of homeless people {#blank#}3{#/blank#} share their story and how they survive day to day.

The man who operates the channel {#blank#}4{#/blank#}(be) formerly homeless and has devoted his life to helping {#blank#}5{#/blank#} homeless, The name "invisible people" certainly suits the channel well. For indeed there are so many "invisible" beings who are suffering every day, both humans and animals, and yet our {#blank#}6{#/blank#} (social) either pays little for people to {#blank#}7{#/blank#} (cruel) treat and kill animals, or completely {#blank#}8{#/blank#} (ignore) those who are in desperate need.

Occasionally, someone who watches the videos posted on that channel is near one of the people interviewed and is able {#blank#}9{#/blank#} (help) in some way. Some of the videos are truly heart-breaking but it's important to see what people go through. We can't turn a blind eye or treat them as if they're invisible. We cannot behave as it's been said, "Worship a homeless man on Sunday, and then ignore a homeless man {#blank#}10{#/blank#} Monday."
