Just as mankind has always had a desire to fly, the human race has wanted to swim under the water since prehistoric times. Pictures of primitive devices to enable people to breathe underwater have been found dating from 3000 years ago, but our dream of moving freely beneath the ocean waves for long periods of time was only realized about 60 years ago, when French diving legend Jacques Cousteau developed the first practical Self Contained Underwater Breathing Apparatus(SCUBA). Since then the sport of SCUBA diving has gone from strength to strength.
Lovers of SCUBA diving like the feeling of weightlessness, the peace and quiet under the water, the ability to move in three dimensions and the sense of adventure they get while on a dive. SCUBA divers often travel to some of the most beautiful and remote places in the world in the search for rare underwater flora and fauna(动、植物). Palau, The Red Sea, The Maldives and Hawaii have many of the most popular diving sites, but recreational divers often have to make do with less exotic local destinations, like the North Sea in Britain.
SCUBA diving is not without its dangers, however. The mixture of nitrogen and oxygen divers breathe underwater, combined with the pressure under the water can be deadly if a diver rises too quickly to the surface, causing a condition called ‘the bends’. Divers can also get lost or trapped when diving on wrecks, and fatalities(死亡)are particularly common in cave diving, where divers add to the dangers of diving by swimming through underground caves filled with water. Diving can also be harmful to the underwater environment. However with proper precautions diving can open up a whole new world, far from the stresses of daily life.
63. What is the writer trying to do in the text?
A. Advertise some popular diving sites.

For thousands of years, mankind has produced plants and animals to create more desired and useful plants and animals. For example, modern com has been produced to such a large size that it is no longer able to reproduce without man’s assistance. Modern dairy cows produce too much milk and if they are not often emptied of milk, they could leak, burst, become infected, and possibly die. Besides, most dogs raised by people can not survive in the wild even with special training.
Since natural evolution is extremely slow and mankind’s selective production programs only take a few generations to produce a completely new species, natural evolution has already taken a back seat to mankind’s production programs. In addition, mankind has successfully killed off several species all together. For example, there are no more European wolves in existence and mammoths (猛犸象) probably died out because of mankind. Even certain diseases have been permanently got rid of from the planet, and dozens of other diseases will soon be too. Again, natural evolution did i»t cause most of the destruction during man’s rule of the world.
Currently, scientists are creating new species with desired characteristics in the lab significantly faster than natural evolution creates new species. In a single generation, new species can be created and destroyed by mankind, while natural evolution could take thousands of years to do the same but only accidentally. Scientists are even able to replace defective (有缺陷的) or damaged genes with different genes to attempt to cure genetic defects. This is something that natural evolution could possibly never correct.
Eventually scientists will even be able to improve the quality of people. For example, imagine not only correcting your eyesight with gene treatment, but also ensuring that all of your children do not receive your old genes of poor eyesight too. Scientists will one day be able to improve the memory and intelligence of your children, so that they will do better in school and achieve more in life. Doctors and scientists will be able to customize (订制) babies before they are born just like picking options at a car store.
1.According to the first paragraph,______ .
A. man-made evolution has improved all species
B. man-made evolution has weakened some species
C man-made evolution can make up for all natural losses
D. natural evolution won’t happen without man’s assistance
2.What does the underlined part “taken a back seat to” in Paragraph 2 mean?
A. Become powerful assistance to.
B. Become a huge barrier to.
C Speeded up the process of.
D. Played a less important role than.
3.What does the third paragraph mainly talk about?
A. Why natural evolution happens so slowly.
B. The way scientists adopt to have genetic defects repaired.
C. The advantages of man-made evolution over natural evolution.
D. How scientists make use of man-made evolution to create new species.
4.What can we infer from the passage?
A. Near-sighted parents will be able to produce babies with good eyesight in the future.
B. Doctors and scientists will be responsible for mass production of babies in the future.
C. It is natural evolution that is to blame for the destruction of European wolves and mammoths.
D. Children can now have their memory and intelligence improved with the help of gene treatment.

The disease malaria(疟疾) has caused trouble to mankind throughout history. In the 1860s as the drug called chloroquine began to lose its effectiveness, malaria began to appear again in Southeast Asia. Every country in the world then poured huge amounts of human resources into discovering another anti-malaria drug In 1964, China put forward the plan to seek a breakthrough from among traditional Chinese medicinal drugs. There was no great discovery until 1981. When Chinese scientist Tu Youyou gave a speech titled" Chemical Research into Artemisinin(青蒿素)”. at an international conference of the WHO. The speech was regarded as a lifeline for malaria sufferers.
Tu Youyou graduated from the Medical College of Peking University. In 1969, just as the research into treating malaria had reached dead end, the 39 year-old Tu, in order to overcome this terrible problem, took on the job as head of a research team into this problem. The first thing Tu did was interview experienced doctors of Chinese medicine. Then she and her colleagues conducted various kinds of experiments on hundreds of kinds of Chinese medicinal herbs, including artemisinin. However, the results were disappointing: even those involving artemisinin, which had been universally well regarded, were less than satisfactory.
But later, when Tu found a relevant passage written by Ge Hong of the Eastern Jin Dynasty (317-420), it occurred to her that high temperatures destroy artemisinin's effectiveness: it needs a low temperature to work properly. The discovery pointed to a brand-new direction for Tu and her research team. Finally, in 1972, an extract(# R40) of it was found to be one hundred percent effective against the disease!
In 2000 the WHO announced artemisinin was a leading anti-malarial drug, and promoted it worldwide. So far, it has been playing a great role in the battle against malaria. Beginning at the age of 39, Tu devoted her fife-te-her reseach. In 2015, at the age of 85 and as the first Chinese scientist, she received a Nobel Prize in Physiology or Medicine. How did Tu manage to accomplish such a great achievement? You probably have the answer to that already.
1.What can be learnt about “chloroquine”from paragraph1?
A.It contributed to Tu’s great discovery.
B.It was discovered by experts in Southeast Asia.
C.It was a breakthrough out of Chinese medicine.
D.It used to be effective against the disease of malaria.
2.What did Tu Youyou do after reading a passage by Ge Hong?
A.She interviewed doctors to collect their experience.
B.She attempted to heat the extract at a low temperature.
C.She made necessary adjustments in each stage of her research.
D.She expanded access to the anti-malarial drug around the world.
3.Which of the following can best summarize the main reason for Tu's success?
A.You reap what you sow.
B.Actions speak louder than words.
C.Don't claim to know what you don’t know.
D.Live and learn through your mistakes or experience.

Just a couple of hours ago, I was on the plane, ready to fly home from London. The flight had been delayed by a few hours so it felt good to be so close to take-off. I had my iPod in place and a new book to read. Then, over the loudspeaker came the pilot’s voice: "The ground crew has found a metal instrument in one tire. We regret that we must cancel this flight."
The passengers’ reactions that announcement led to were interesting. One man close to me began to argue with a flight attendant. A couple in another row complained loudly. A businessman in a black suit actually kicked the seat in front of him. Yet some passengers responded differently. An elderly gentleman smiled as he helped others take their bags down from the overhead compartments (隔间). A teenager, rather than trying to rush off the plane like most of the other passengers, stopped to help a woman with a disability. The lady sitting next to me laughed and said: "Hey, it’s not the end of the world..." before she made a call to her kids and shared her adventure with them. The wisest among us have a remarkable ability to maintain grounded when times get tough.
No life is perfect; mine certainly isn’t. We all must face challenges, both large and small. You and I have the power to choose to rise above the external circumstances. We always have the choice to be strong and kind when things fall apart.
That’s grace under pressure. My seatmate was right — things could have been so much worse. Anyway, I am safe. I have my health. I have two wonderful children. I have work I love and so much to be grateful for. Sure I now have to wait a few hours to catch the next flight home.
1.What caused the passengers’ different reactions directly?
A.The loudspeaker. B.The delay of the flight.
C.The ground crew’s fault. D.The pilot’s announcement.
2.Who turned his anger on the seat?
A.The teenager helping the disabled. B.The old man taking bags down.
C.The man in a dark suit. D.The man close to me.
3.What did the woman sitting next to the author do?
A.She assisted a disabled woman.
B.She made a phone call to her family.
C.She helped others carry their luggage.
D.She told moving stories to her children.
4.What can we learn from the story?
A.Our life is full of ups and downs.
B.It is natural to be scared under pressure.
C.We should help each other in times of difficulty.
D.We should be positive and calm when life is hard.

As a young girl growing up in the 1930s, I always wanted to fly a plane, but back then it was almost unheard of for a woman to do that. I got a taste of that dream in 2001, when my husband arranged for me to ride in a hot air balloon for my birthday. But the experience turned out to be very dull. Around that time, I told my husband that I wanted to skydive. So when our retirement community announced that they were having an essay competition and the topic was an experience of a lifetime that you wanted to have, I decided to write about my dream.
In the essay, I wrote about my desire to skydive, stating George Brush Sr. did it at age 80. Why not me? I was just 84 and in pretty good health. A year went by and I heard nothing. But then at a community party in late April 2009, they announced that I was one of the winners. I just couldn’t believe it. Inspired by this, I decided to realize my dream, even though some of my family members and my doctor were against it.
On June 11, 2009, nearly 40 of my family and friends gathered in the area close to where I would land while I headed up in the airplane. My instructor, Jay, guided me through the experience. The plane was the noisiest one I had ever been in, but I wasn’t frightened—I was really just looking forward to the experience. When we reached 13,000 feet, Jay instructed me to throw myself out of the plane. When we first hit the air, the wind was so strong that I could hardly breathe. For a second I thought, “What have I gotten myself into?” But then everything got calmer. We were in a free fall for about a minute before Jay opened the parachute(降落伞), then we just floated downward for about five minutes. Being up in the clouds and looking at the view below was unlike anything I have ever felt—much better than the hot air balloon. I was just enjoying it.
Skydiving was really one of the greatest experiences of my life. I hope other people will look at me and realize that you don’t stop living just because you are 84 years old. If there’s something you want to experience, look into it. If it’s something that is possible, make it happen.
1.The author mentioned George Bush Sr. in her essay to ________.
