Alice: Frank, have you got a hobby?

Frank: Well I don't think I have one. How about you?

Frank: How Interesting! How {#blank#}4{#/blank#} have you been collecting stamps?

Alice: 12 years so far, since I was 9.

Frank: You must have a lot of stamps then.

Alice: Sure, I have thousands of stamps from more {#blank#}5{#/blank#} 20 countries.

Frank: Wow, unbelievable! I also want to have a hobby, {#blank#}6{#/blank#} I just don't have the time.

Alice: What {#blank#}7{#/blank#} (keep) you so busy?

Alice: We read books and organize discussions.

Frank: {#blank#}10{#/blank#} (sound) great!

Franklin's life is full of charming {#blank#}1{#/blank#} (story) which all young men should know—how he sold books in Boston and became the guest of kings in Europe; how he was made General Franklin, only to quit and help to organize the army {#blank#}2{#/blank#} was better than the trained troops of England and Germany.

    This poor Boston boy, {#blank#}3{#/blank#} a day's schooling, became master of six languages and never stopped {#blank#}4{#/blank#} (study). This apprentice（学徒）received degrees and diplomas from many colleges, and became forever {#blank#}5{#/blank#} (remember) as “Doctor Franklin”, philosopher, scientist and political leader.

    Self-made, self-taught, the candle maker's son {#blank#}6{#/blank#} (give) light to all the world; the street bookseller set all men singing of liberty; the apprentice became the most outstanding man across the world, and brought his native land to praise and honor him.

    He built America, for {#blank#}7{#/blank#} our nation is today is largely due to the management, the forethought, the wisdom, and the ability of Benjamin Franklin. He belongs to the world, but {#blank#}8{#/blank#} (especial) he belongs to America. The people around the world honored him while he was living. He is still regarded as {#blank#}9{#/blank#} loftiest man by the common people today after {#blank#}10{#/blank#} death. And he will live in people's hearts forever.

    Eating organic food will not make you healthier, according to researchers at Stanford University, although it could cut your {#blank#}1{#/blank#}(expose) to pesticides（杀虫剂）. They looked at more than 200 studies of the content and {#blank#}2{#/blank#}(associate) health gains of organic（有机的） and non-organic foods. Overall, there {#blank#}3{#/blank#}(be) no difference in the nutritional content, although organic food was 30% less likely {#blank#}4{#/blank#}(contain) pesticides.

    The researchers looked at 17 studies comparing people who ate organic {#blank#}5{#/blank#} those who did not and 223 studies {#blank#}6{#/blank#} compared the levels of nutrients, bacteria, and pesticides in various foods. However, none of the human studies ran for longer than two years, {#blank#}7{#/blank#}(make) conclusions about long-term{#blank#}8{#/blank#}(outcome) impossible. And all of the available evidence was{#blank#}9{#/blank#}(relative) weak and highly variable, which the researchers said was unsurprising because of all the different variables.

    Dr Crystal Smith-Spangler, the lead researcher, said “Some believe that organic food is always healthier and more nutritious. But as {#blank#}10{#/blank#} matter of fact there isn't much difference between organic and conventional foods, if you're an adult and make decisions based simply on your health.”

    {#blank#}1{#/blank#}(eat) an egg a day may lower your risk of cardiovascular disease, a study of more than 400,000 adults in China{#blank#}2{#/blank#}(suggestion).

    Daily egg eaters had an 18% lower risk of dying from cardiovascular(心血管的) disease, {#blank#}3{#/blank#}manifests(表现，显现) as heart attacks and strokes,{#blank#}4{#/blank#}(compare) with adults who avoided eggs, according{#blank#}5{#/blank#}the research published Monday in the journal Heart.

    {#blank#}6{#/blank#}(Common) called heart disease, cardiovascular disease includes heart{#blank#}7{#/blank#} (fail), arrhythmias(心律不齐) and heart valve problems in addition to strokes and attacks. Raised blood pressure, carrying too much {#blank#}8{#/blank#}(weigh) or obesity, and elevated(提升) blood sugar all contribute to the risk of cardiovascular disease, which{#blank#}9{#/blank#} trigger (引发)by unhealthy diet, physical inactivity, smoking and{#blank#}10{#/blank#}(harm)use of alcohol.

    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.

Living in a city can be stressful. But people in Bogota, Colombia have found a place to help ease stress and get a{#blank#}1{#/blank#}(peace) break from busy life. The place is a {#blank#}2{#/blank#}(protect) park for hummingbirds(蜂鸟).

The park is at the top of Montserrat Hill. The area{#blank#}3{#/blank#} (contain) a forest which has turned into a quiet place for both people and birds. As the hummingbirds fly from flower to flower, some people take pictures with cameras or phones.

"Sometimes it doesn't seem real because we are close to{#blank#}4{#/blank#} city with the population of 8 million,{#blank#}5{#/blank#} create noise every day," said Camino Carter, a caretaker in the park. His job is{#blank#}6{#/blank#}(mix) water and sugar that is put in bird feeders.

{#blank#}7{#/blank#}(visitor) to the park can see between 25 to 35 different species of birds. But ten years ago, the hill was {#blank#}8{#/blank#} (complete) destroyed, and no trees {#blank#}9{#/blank#}(leave) on it.

Luckily, measures were taken by the government. Workers began to replant local trees and flowers to bring the forest back{#blank#}10{#/blank#} life.

Presently, there are 115 species of birds, including 18 kinds of hummingbirds in the park.
