What do you do if you are hit in the mouth and one of your teeth is knocked out? A dentist(牙医)may be able to put the tooth back in for you, but you have to get to the dentist first．In the meantime, you have to store the tooth so that it will stay healthy．
The simplest thing to do is put the tooth back into your mouth, or you could put it in milk．Frank Courts, a dentist at the University of Florida, worked with other researchers to find the safest way of keeping knocked-out teeth．He tried putting teeth into milk, into water, and into cell-culture medium(细胞培养液)．He also tried, just drying the teeth in the open air．He used teeth that had to be removed from people’s mouths for various reasons．The teeth were put into one of the solutions(溶液)or stored in the air for one hour．Then cells from the root of the teeth were scraped-off the teeth．Dr．Courts and the others then studied how healthy these cells were．
The cell-culture medium worked best to keep a knocked-out tooth healthy outside the mouth．However, few people keep cell-culture medium handy at home or in school．
The next best thing was milk．But Dr．Courts said that the best thing of all was to wash the tooth and put it right back into its socket(牙槽)in the mouth．For some people, though, this is just too painful or upsetting．So milk will do, until you get your tooth (and your mouth)to a dentist．
1.This passage is mainly about ．
A. how a dentist can save a knocked-out tooth
B. how to keep a knocked-out tooth healthy
C．how Dr．Courts and other researchers made their experiments
D．how to put a knocked-out tooth back into its socket
2.The best way to keep a knocked-out tooth healthy outside the mouth is to store it .
A．in cell-culture medium B．in milk C．in water D．in the open air
3.Milk can be used instead of cell-culture medium to put a knocked-out tooth in because ．
A．milk works better to keep the tooth healthy B．milk causes less pain
C．cell-culture medium is not usually handy D．cell-culture medium is more expensive
4.“Dr．Courts said that the best of al1 was to wash the tooth and put it right back into its socket in the mouth．”In the sentence, the word “best” means .
A．cheapest and healthiest B．least painful and cheapest
C．quickest and least painful D．easiest and healthiest

Have you ever imagined what human beings will look like in the future? Well, now you don’t have to.
According to AsapScience, a Canada-based video channel that touches on many different science topics, humans will be very different creatures 1,000 years from now.
Artificial intelligence, genetic engineering and climate change will work together to change our bodies greatly, according to a video recently published by the channel.
We could, for instance, develop red eyes as our DNA changes, and have darker skin because of global warming.
The video painted a picture of a future world in which our bodies are part human, part machine. Nanobots, or tiny robots, will be put into our bodies, improving our abilities.
“No longer will we be limited by our own physiology. We will truly become a mixture of biology and machine on the inside,” says the video.
Meanwhile, designer babies will cause future generations to grow into intelligent, attractive people. As global warming takes hold, humans will also be skinnier and taller, as this body shape deals with heat better.
In fact, Cadell Last, a researcher at the Global Brain Institute located in Belgium, believes change may happen even faster than this.
As he said in a paper recently published in Current Aging Science, mankind is already going through a major evolutionary change. In less than four decades, Last claims, we will live longer, have children in old age and need artificial intelligence to finish daily tasks.
“Your 80 or 100 is going to be so radically different than your grandparents,” Last said. Instead of living fast and dying young, he believes humans will live slow and die old.
“The biological clock isn’t going to be around forever,” he added, and said that people could pause it for some time using future technology.
Just a few hundred years ago, most humans were working in the fields, while nowadays more and more are getting an education. These are just predictions, and no one can be sure how human beings will evolve in the future. But with such large changes in our environments, it seems likely that we will all look very different one day.
1.Which of the following factors could play a role in the appearance of future humans, according to the text?
A. Advanced technology and global warming.
B. Medicine that fights aging and genetic engineering.
C. The Internet and artificial intelligence.
D. The cold weather and the dangers of machines.
2.The video released by AsapScience said that .
A. humans will be thinner and shorter
B. future humans’ bodies will be part machine
C. humans will develop red eyes that will enable them to see clearly at night
D. tiny robots will be put in humans’ minds and will give them super abilities
3.Which of the following would Cadell Last probably agree with?
A. Future babies will be designed according to their grandparents’ wishes.
B. Our increasing dependence on artificial intelligence will threaten our survival one day.
C. Future technology will pause our biological clocks so that humans live slower and longer.
D. In less than four decades, humans will have a sudden genetic change that will make us rely on artificial intelligence.
4.The main purpose of the article is to .
A. tell us about a prediction of how humans will look in the future
B. offer us different theories on how humans will evolve in the future
C. encourage us to be imaginative about how humans will look in the future
D. inform us what kinds of factors Could influence how humans will look in the future

The measure of a man's real character is what he would do if he knew he would never be found out. ---Thomas Macaulay
Some thirty years ago, I was studying in a public school in New York. One day, Mrs Nanette O'Neill gave an arithmetic 36 to our class. When the papers were 37 she discovered that twelve boys had made exactly the same mistakes throughout the test.
There is nothing really new about 38 in exams. Perhaps that was why Mrs O'Neill didn’t even say a word about it. She only asked the twelve boys to 39 after class. I was one of the twelve.
Mrs O'Neill asked 40 questions, and she didn't 41 us either. Instead, she wrote on the blackboard the 42 words by Thomas Macaulay. She then ordered us to 43 these words into our exercise-books one hundred times.
I don't know about the other eleven boys. Speaking for 44 I can say:it was the most important single 45 of my life. Thirty years after being introduced to Macaulay's words, they 46 seem to me the best yardstick(准绳), because they give us a way to _47____ourselves rather than others.
48 of us are asked to make 49 decisions about nations going to war of armies going to battle. But all of us are called 50 daily to make a great many personal decisions. 51 the wallet, found in the street, be put into a pocket or turned over to the policeman? Should the 52 change received at the store be forgotten or 53 ? Nobody will know except 54 . But you have to live with yourself, and it is always 55 to live with someone you respect.
