Today I went to a conference, {#blank#}1{#/blank#} two students had a debate about the strengths and weaknesses of the Internet.

    The first speaker talked about the positive {#blank#}2{#/blank#} (effect) of the Internet on our lives. The first is its value for people who {#blank#}3{#/blank#} (look) for information. For example, with the touch of a button {#blank#}4{#/blank#} the click of a mouse, a student will find abundant information at his or her command. The second is our ability {#blank#}5{#/blank#} (relate) to others through the Internet and it is especially important for disabled people {#blank#}6{#/blank#} can't leave their homes.

    The {#blank#}7{#/blank#} (two) speaker talked about the negative effects of the Internet on our lives. For example, some experts think that the outcome of spending too much time on the Internet ii difficulty in {#blank#}8{#/blank#} (form) social bonds. They were also quite explicit about how heavy Internet users spend {#blank#}9{#/blank#} (much) time with their Internet friends than their real-life friends from school and work.

    Both sides presented lots of statistics to support their arguments. My own judgment is that though the Internet is. {#blank#}10{#/blank#} (benefit), we should use our intelligence and not be a slave to it!

    Do your family often take a trip? For most families, a trip in a car to an unfamiliar (不熟悉的) area often goes with the question about which way {#blank#}1{#/blank#}(take). This is not the case, however, in the Williams family. They never get {#blank#}2{#/blank#}(lose) when five-year-old Daniel is with them. That's because Daniel has the unbelievable{#blank#}3{#/blank#}(able) to tell them the best way to get from one place to another anywhere in England and what's more, he doesn't need a map-he can do it{#blank#}4{#/blank#}thinking.

    Daniel{#blank#}5{#/blank#}(be) interested in place names since he first learned to talk. When he was about three, he started asking his parents questions about how the roads they drove along joined up, and{#blank#}6{#/blank#}soon became obvious that he had a super memory for maps. He had no difficulty{#blank#}7{#/blank#}(remember) the roads he saw from the car window.

    Now, after school, Daniel's {#blank#}8{#/blank#}(favor) game is drawing maps of the road systems in the places he hasn't visited. His parents have no idea where his particular talent comes from{#blank#}9{#/blank#}no one else in the family has it. Although he has other{#blank#}10{#/blank#}(hobby) Daniel's greatest goal in life is to become a mapmaker.

    There's no such thing as living alone. Never mind if you're {#blank#}1{#/blank#} only person in your house and have no dog, no cat, not even fish. You still have got several billion {#blank#}2{#/blank#} (roommate) — and so do we all. Some of them are harmless, some are {#blank#}3{#/blank#} (actual) helpful and some could even kill you. They are, of course, bacteria, fungi(菌类) and viruses, and like it or not, they're on you, around you, and deeply within you. The fact that bacteria life is everywhere is not{#blank#}4{#/blank#} (surprise). It's something you {#blank#}5{#/blank#} (learn) from your childhood when your mother told you not to drink water from someone else's glass. There are lots of bacteria {#blank#}6{#/blank#} are living in your tea kettle. There are bacteria {#blank#}7{#/blank#} (sleep) with you on your bed. Scientists are beginning {#blank#}8{#/blank#} (realize) the richness of the microbiome (微生物群系) — which is as complex as the ones {#blank#}9{#/blank#} (find) in oceans, rainforests, deserts and woodlands. Your house has a microbiome and {#blank#}10{#/blank#} do you.

    As you know, science plays {#blank#}1{#/blank#} very important role in our education. Do you want to keep up {#blank#}2{#/blank#} the latest research and discoveries in science? There are many good websites {#blank#}3{#/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#}4{#/blank#} (cover) a wide range of subjects. The articles are intended for younger readers, but adults will find this site {#blank#}5{#/blank#} (suit) 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 articles just about anything that {#blank#}10{#/blank#} (be) related to the science fields you are interested in.
