The Internet is an amazing information resource. Students, teachers, and researchers use it as {#blank#}1{#/blank#}searching tool. Journalists use it {#blank#}2{#/blank#}(find) information for stories. Doctors use it to learn more about unfamiliar diseases and the {#blank#}3{#/blank#}(late) medical development. When we are talking about it , it {#blank#}4{#/blank#} (use) by ordinary people for shopping, banking, bill-paying, and communicating with family and friends. It has the magical power to connect one with people from {#blank#}5{#/blank#} countries and cultures. However, {#blank#}6{#/blank#} the Internet has many advantages , there are also certain fears and concerns connected with it. One concern relates to a lack of control over {#blank#}7{#/blank#}appears on the Internet. On television and radio there are restrictions (限制）on what kinds of programs can  be broadcast, {#blank#}8{#/blank#} on the Internet it is not the case. Parents cannot determine what is suitable {#blank#}9{#/blank#} their children to see because the {#blank#}10{#/blank#} (appear) of any information is not under their control.

    Qiang Shuping was so busy making cloth shoes {#blank#}1{#/blank#} she didn't even rest during the Dragon Boat Festival holiday. The woman from Baipu County, Jiangsu Province, {#blank#}2{#/blank#} (make) shoes since she was 19 years old, and this year marks her 3lst year making cloth shoes.

    She spends the entire day in her tiny studio, which {#blank#}3{#/blank#}(measure) less than 10 square meters altogether, filled with cloth shoes in {#blank#}4{#/blank#}(variety) stages of completion.

    Nowadays, many stores make cloth shoes {#blank#}5{#/blank#}(use) machines, but Qiang sticks to the technique of making shoes entirely {#blank#}6{#/blank#} hand. She say the shoes {#blank#}7{#/blank#}(produce) by machine are not of the same quality as handmade ones. The handmade cloth shoes are more durable（耐用的）and comfortable, {#blank#}8{#/blank#} (soft), and absorb sweat better.

    Some people buy cloth shoes out of nostalgia（怀旧）, while others trust {#blank#}9{#/blank#}(they) quality. Making shoes isn't a profitable job, but Qiang still insists as she wants to preserve the craft and pass it down to the younger generation.

    Handmade cloth shoes are also called qiancengdi (shoes with a thousand layers), {#blank#}10{#/blank#} can date back to the ancient Zhou Dynasty. In 2009, the making technique of qiancengdi was listed as the national intangible cultural heritage（非物质文化遗产）

    I enjoy {#blank#}1{#/blank#}(climb) mountains whenever I can find the time to do so. Tom and Mike are my best friends and both of {#blank#}2{#/blank#}also like sports. Two years ago, the three of us {#blank#}3{#/blank#}(go) up to Mt. Lushan. Instead of taking a bus, which is{#blank#}4{#/blank#}(comfortable), we preferred to climb. We started from the foot of the mountain early in the morning, chatting all the way. After climbing for one and a half {#blank#}5{#/blank#}(hour), we saw two mountain paths before us. We could not decide {#blank#}6{#/blank#}to choose. In the end, we took the right path, {#blank#}7{#/blank#}(think) that might be a short cut. But we were wrong. We could not find our way out. Lost in the mountain, we had to use our hands and feet{#blank#}8{#/blank#}(make) our way. We began to cry for help {#blank#}9{#/blank#} nobody answered. It was not until darkness fell{#blank#}10{#/blank#} we found a right path leading up to a paved road.

    In the last quarter of the twentieth century, {#blank#}1{#/blank#} the 14 million foreign visitors a year are far too much of a good thing.

Color blindness is very common. It affects{#blank#}1{#/blank#} (rough) 1 in 12 men and 1 in 200 women in the world. People {#blank#}2{#/blank#} blindness can't see colors in a normal way.

There are {#blank#}3{#/blank#}(variety) causes of color blindness. For the majority of color-blind people, color blindness is genetic, although some people become color-blind as a result of other diseases, such as diabetes(糖尿病), or they have {#blank#}4{#/blank#} condition over time due to the aging process, etc.

Most color-blind people can see {#blank#}5{#/blank#} (thing) as clearly as other people, but they are unable to fully "'see" red, green or blue light. There are different types of color blindness but there are extremely rare cases {#blank#}6{#/blank#} people are unable to see any color at all. The most common color blindness is red/ green color blindness. Although {#blank#}7{#/blank#}(know) as red/green color blindness, it doesn't mean {#blank#}8{#/blank#}(suffer) will only mix up red and green. It means they mix up all colors that have some red or green as part of the whole color.

The effects of color blindness can {#blank#}9{#/blank#} (classify) into mild，moderate(中等的) or severe. About 40% of color-blind people are even unaware that they're color-blind. Statistically speaking, most people {#blank#}10{#/blank#} (have) a moderate form of red/ green color blindness can only identify 5 colored pencils from a standard box of 24 pencil crayons.
