【題目】
You're not the same person you were as a child. You're not even the same personyou were five years ago. We don't just mean your personality. While we'd love tostart a never-ending discussion over the “true self”,we're here to talk about thecells(細(xì)胞)in your body.
Do you know how your fingernails and hair are constantly growing and replacingthemselves? The same thing happens almost everywhere in your body. Your outerlayer of skin makes way for fresher skin, and inside your veins(血管),blood cells turn over to make wayfor fresh blood. It's probably no surprise that these types of cells are short-lived, even some of the mostseemingly permanent(永久的)parts of your body replace themselves over time-including your bones.
Strong as your bones might seem, the cells they're made of won't last a lifetime. Bones are masters at rebuilding themselves, which is why most broken bones can heal on their own into the right shape.
Bones have special cells called osteoclasts(破骨細(xì)胞)whose job is to break down bone, even if itisn't broken, and send the minerals into the blood stream. This may sound frighteningly like your bonesare wearing away, but your body knows what it's doing. As osteoclasts break down bone, osteoblasts(成骨細(xì)胞)build up new bone to replace the old. By the end of each year, about 10 percent of yourentire adult skeleton will have been rebuilt through this process.
If 10 percent of your bone breaks down every year, it must take about ten years to renew 100percent of your skeleton. That would be a great guess, and it lines up nicely with the medical myth thatthe human body's cells are fully replaced every seven years, but the body is a bit more complex. That10 percent is just an average-some bone grows faster than that, and some grows slower. While someparts of your bone will turn over quickly, other parts will stick around for decades. In fact, most bonecells could live as long as 50 years.
So before you get wrapped up in an identity crisis(危機(jī))about the cells in your body disappearingon you, know that you can lose some hair and you can cut your nails, but the bones of you aren't goinganywhere-at least not very soon and not all at once.
【1】Which of the following is TRUE according to the passage?
A. All the cells in our body are the same ones that we were born with.
B. Our blood cells are constantly growing and replacing themselves.
C. It must take about 10 years to rebuild 100 percent of our skeleton.
D. Osteoblasts can break down skin and also rebuild it over time.
【2】The underlined words "wearing away" probably mean“__”.
A. building upB. taking offC. dying outD. turning on
【3】What does the passage mainly talk about?
A. Our skeleton seems permanent but renews itself over time.
B. It is not surprising that some cells in our body are short-lived.
C. There are two types of cells in our bones: osteoclasts and osteoblasts.
D. We are not the same person we were five years ago because of personality.

【題目】
China, with Four Great Inventions, in ancient times, has once again showed its ability to change the world with its “new four great inventions”: high-speed railways, electronic payments, shared bicycles and online shopping.
The four innovative ways of life are most popular among young people, according to a survey by the Belt and Road-Research Institute(一帶一路研究院) of Beijing Foreign Studies University.
“The ‘new four great inventions’ are all related to China’s high-tech (高科技), which made the lives of people easier in China,” said Wu Hao, the director of Beijing Foreign Studies University.
“My wallet is no longer in use. I can buy and eat whatever I want simply with my phone,” said Lin Jinlong, a foreign student from Cambodia, adding that “Even pancake sellers are using Alipay (mobile payment). We can also order food at home, which is super convenient. If I were at home in Cambodia, I would have to go outdoors.”
As a big fan of bicycles, he also showed his love for China’s shared bicycles, saying that “shared bikes are bringing cycling (騎單車) back to people’s lives---and they are making public transport(公共交通) more convenient and less crowded, and encouraging people to be more active.”
Rebacca Fannin, the founder of Silicon Dragon(硅谷之龍), noted that China is beginning to lead in innovation in some ways.
“It is increasingly clear that China is inventing and no longer copying western ideas. It is also increasingly clear that China is leading in many ways such as social messaging app WeChat,” she said.
