Humans' Greatest Achievements

    The Earth is 4. 5 billion years, old, but the human race has lived on it for just 200,000 years. In that short time, we have achieved some amazing things.

    . The list is almost endless. The invention of the airplane has changed our lives. The discovery of antibiotics (抗生素) has saved the lives of millions of people. Can you imagine living without electricity? What about the printing press(印刷术)? Without the printing press, you wouldn't be reading this. In the last 50 years, there have been great achievements in communication, such as radio, TV, computers, the Internet, and smartphones (智能手机). . What about the arts? The arts have brought pleasure to many people, but are the Beatles and Bach more important than antibiotics? ?

    Finally, we must not forget humans' early achievements. ， We can't imagine modern life without cooked food and cars.

    What are humans' greatest achievements? To answer the question, we need to decide what we mean by" great" . ? Or is it just something that makes us say "Wow", like the Great Wall? What do you think?

    I bought a jasmine plant for my office. When I bought it, I was told it would bloom(开花) and the sweet smell would fill my office. I had the plant for two months, and every day I looked at it, but there weren't any flowers or pleasant smell. I was not happy, so I gave the plant to my friend Linda.

    One day, another friend Mary called and invited me to her office. When I walked in, her jasmine flowers surprised me. I reached out to touch the flowers. Mary cut some and gave them to me. I couldn't help smelling them. Surrounded by the sweet smell of only a handful of these flowers, I suddenly understood something.

    Mary bought her plant the same time I did. It took a year for her jasmine to bloom. I was so impatient for mine to bloom; regretfully, I gave it away.

    In a way my life is like the jasmine plant. I need to be patient and let things happen.

    Last Sunday Linda told me that she was going abroad the next week. Before she left, she returned the plant to me. This time I am going to wait. I have learned that when we want something in our life, we have to be patient. I am slowly learning to 6 have; that patience to wait for my jasmine to bloom.

    What should you do if you want to have a nice photo taken? Whether it's work or fun, the most important thing is lighting. If you get bad lighting, you will look bad, too. Know where the light is. You don't want it below you or above you; you want it to shine directly at you.

    The key thing is no shadow(阴影). If you are being photographed outside, do it in the morning, or wait till the 2 o'clock shadow has passed. Also don't let pictures in the magazines stress you out all the pictures are taken by great photographers. And all the faces have had pimples (丘疹;粉刺) taken out by computers.

    Tip your head and learn what angles(角度) work with your face. Everyone is different. So you have to learn what suits you. You can practise in Photo Booth for as long as it is your turn, to learn what angles suit your face. Tip. Your neck to make it look longer, make eye contact with the camera. No one can look bad if they smile.

    For long legs, point one leg into centre of the frame and get the photographer to shoot looking up your body. For just leg shots, lie upside down and raise legs in the air for the best angle. And your legs will look thinner and be in better shape.

    Keep shoulders back.

    Always have the mouth slightly open, enough to put a penny between your lips, as this will make your lips look fuller.

    Lower your eyes and then look up just as the shutter (快门) is clicked for full eyes.

    Try to catch every perfect photogenic moment!

    In America, students in high school must take certain subjects like English, social studies, math, PE and science. And they also choose among elective subjects(选修课) to complete their high school education. .

    Each student in the school has their own locker(锁柜) for books. and students can own a small space they can decorate with posters and favourite things.

    Most high schools have at least one sports team. Schools often offer football, baseball, softball, basketball, volleyball, tennis and soccer. .

    Many high school students have part-time jobs by the age of 15 or 16, some even earlier. , but later they will probably get a job at a fast food restaurant, video store, or clothing shop.

    Sixteen is the legal(法定的) driving age in most states, and students usually want to own a car as soon as they can. . Others would like their children to earn enough money to afford a used vehicle. Many teenagers feel it's necessary to own one, and will do whatever it takes to be able to drive.
