Jane Goodall is a famous scientist. For more than 40 years, Goodall lived mostly in Tanzania in East Africa, studying chimpanzees.

    As a young child, Jane Goodall was interested in animals. She grew up in the English countryside and was always climbing trees or riding horses.

When Jane was 23, she got a chance to go to Africa even though she had never been to college，she got a job with a famous scientist named Louis Leakey.

One day Louis Leakey said he needed a volunteer. He needed someone to go to a lake in Tanzania to study a kind of chimpanzees. Jane was excited.

    On July 16,1960, she began her exploration（探索）. At first, the chimpanzees ran away from Jane. But with time passing，they got used to her being around.

    Every day，Jane would follow the chimpanzees，taking notes on their behavior. She learned many new things about chimpanzees. She watched how a chimpanzee made a tool. She learned how some chimpanzees became good leaders. She watched how mother chimpanzees raised their children. She watched animals get angry and get upset. She wrote everything down so others would understand animals as she did. She learned that if you pay really close attention to animals，you will understand what they are “saying”.

    Running a marathon (马拉松) is difficult enough. Doing it with eyes closed for 26.2 miles is more difficult. But that's exactly what Mike Bruno plans to do during the Pittsburgh marathon.

    He's doing this for his 7-year-old daughter, Cassie, who doesn't like to communicate with others and has been blind since birth. “Having a blind daughter clearly has caused me a lot of trouble,” Bruno said. “ But it doesn't matter. I love my daughter. I hope to get a better understanding of how she deals with her daily life. I hope this journey will finally make me a better father to guide Cassie through her life.”

    “When the doctor told us 'Your baby is not going to see', that was the most terrible experience we had ever had,” said Bruno.

    “Sometimes I walk around the house with my eyes closed to see what it's like for her,” said Cassie's older sister, Carly, 9 years old. “It's kind of scary. You don't know where everything is.”

    But Cassie has fought against difficulties, and her father plans to do the same. “I closed my eyes, and I got ready, and then I tried running, just to see what it is like for her,” said Mike Bruno. “I want everyone to know it's OK. It's OK to ask us questions, but it's not OK to look at us and point to us with surprise. If you'd like to ask us, we will be happy to tell you our story. ”

Traditional Chinese Medicine，also called "TCM"，is an ancient system of traditional medicine.It has developed for thousands of years and is an important part of Chinese culture.Today people in 183 countries and areas are now using TCM.Massage（按摩），Guasha，Qigong，tai chi and acupuncture （针灸） are some common kinds of treatment of TCM.Chinese massage can make you relaxed and fresh.In acupuncture，doctors put long needles（针） into the patients' heads，faces，arms...It takes away pain，though the look is funny.

The earliest medical classic is in China.Huangdi's Classic on Medicine（黄带内经） came out more than 2，000 years ago.The book is about the relationship between man and nature.In Chinese culture，yin and yang are the two parts of nature.Nature .keeps balanced if yin and yang work well together.According to TCM，imbalances（不平衡） in the human body can lead to health problems，many TCM treatments focus on restoring this balance.

To many people's surprise，for some health problems，a doctor of TCM will not give you medicine.Instead，he may give you just a food plan and right ways to eat.For example，TCM thinks it's wrong to eat on the way to school，at our desk，or in front of the TV.But here are correct ways：Sit down to eat.While eating，turn off the TV and get away from the work desk.Eat seasonal foods.Do not miss any of the three meals.

Hello, everyone. My name is Betty Smith. Betty is my 1 name and Smith is my family name. You can call(称呼) 2 Betty. I'm from America, 3 I'm in Beijing with my dad and mum now. 

I'm a 4 in Beijing No. 2 Middle School and I'm in Class 4 Grade 

7. There are 24 boys and 22 girls in my 5 . My classmates are all 6 to me and we are good friends. My Chinese is not very good and they often 7 me with it after class. The teachers are nice to me 8 . 

I like Beijing. Beijing is very 9 and there are many good places to go. But I don't like the 10 here. It's too hot in summer. 

The weather in the Northern and Southern Hemispheres(半球) is different. It is fun {#blank#}1{#/blank#} (think) that when it is cold in one place, it is hot in another. The Earth's tilt(地球轴线) is the reason for the different {#blank#}2{#/blank#} (season). This means that while one hemisphere is tilted(倾斜) towards {#blank#}3{#/blank#} Sun, the other is tilted away from it.

{#blank#}4{#/blank#} it's winter in the North, it's summer in the South. Students in the Southern Hemisphere look forward to {#blank#}5{#/blank#}(sperd) summer vacation at the beach, while those in the Northern Hemisphere enjoy building snowmen during {#blank#}6{#/blank#} (they) winter holidays.

There {#blank#}7{#/blank#} (be) holidays in both hemispheres, but the weather makes them different. For example, {#blank#}8{#/blank#} special nights like New Year's Eve, people all over the world get together. Because of the different weather, fireworks might go off over {#blank#}9{#/blank#} (snow) places or near the beach, making each {#blank#}10{#/blank#} (celebrate) special.

So, the Earth's tilt not only gives us different weather but also makes our traditions unique.
