26、 There are many places to go on safari in Africa, but riding a horse through the flooded waters of Botswana’s Okavango Delta must be one of the world’ most exciting wildlife journeys.
Several safari camps operate as the base for this adventure(冒险经历), providing rides twice a day to go deep into the delta. The camps have excellent horses, guides and lots of support workers. They are famous for providing a great riding experience.
The morning ride, when the guides take you to beautiful, shallow lakes, is more active. It is unlike any other riding experience. With rainbows forming in the splashing water around you and the sound of huge drops of water bouncing off your body and face, it is truly exciting. You are very likely to come across large wild animals, too. On horseback it is possible to get quite close to elephants, giraffes and many other animals. The sense of excitement and nervousness rise suddenly though, as does your heartbeat, as you move closer to them.
In the evening, rides are usually at a less exciting and unhurried pace, with golden light streaming across the grassy delta and the animals coming out to eat and drink. Though they are peaceful and slow, rides at this time of day are still unforgettable. As the sun’s rays pass through the dust kicked up by the horses, the romance of Africa comes to life.
Back at the camp you can kick off your boots and enjoy excellent food and wine. Looking back on your day, you will find that a horseback Safari is as close as you will ever come to answering the call of the wild.
【1】What does the underlined word “They” refer to?
A.Flooded waters B.Safari camps
C.Wildlife journey D.Special rides
【2】What does the writer find most exciting about a horse safari?
A.Seeing and feeling the real African life.
B.Enjoying good food and wine at the camp.
C.Hunting large animals just as our ancestors did.
D.Being part of the scene and getting close to animals.
【3】Compared to the morning ride, the evening ride is ________.
A.wild B.relaxed
C.fast D.active
【4】The author introduced the riding experience in the Okavango Delta mainly by________.
A.Following time order B.Following space order
C.Giving answering questions D.Giving examples
27、My wife and I went to this vegan(严格的素食主义的) restaurant to give it a try. As we were eating our pepper and salt tofu, a young lady named Debra walked in. She wasn't aware that the place is vegan and was looking for some meat. My wife and I talked up the place and invited her over to try some of our tofu. Debra tried it, nodded and went out.
After a few minutes, she and her mother both walked back in. We were having the rest of our meal at that time, so we told her what we had ordered. Debra then asked the waitress to just repeat our order for them. Next , Debra said. "And we want to pay for their meal", pointing to my wife and me. We tried to say no, but Debra wouldn't listen.
That was not the end ofit. Hugs were in order. Debra came over to our table and my wife got up to hug her. Debra hugged my wife and put $ 100 into her hand. My wife firmly said NO, but Debra insisted. Debra kept talking about our kindness, and we did the same about hers and her mother's.With tears in the eyes, the workers were blown away by this whole exchange between four strangers.I left the waiters and waitresses a tip that would cover all ofour meals and we were on our way.
I've been witnessing so much kindness, especially over the last few years, as I began to pay more attention. We now have a new favorite restaurant and every time we go there my plan is to pay for someone else's meal.

28、 Recently, a scientist did some experiments. He left a group of 4-year-olds in a room with a bell and a candy. If they rang the bell, he would come back and they could eat the candy. If, however, they didn’t ring the bell and waited for him to come back on his own, they could then have two candies.
In the videos of the experiments, he can see the children hiding their eyes, trying to exercise self-control so they can wait and get two candies. The results are different. Some broke down and rang the bell within a minute. Others lasted 15 minutes.
The children who waited longer went on to get higher academic scores. They got into better colleges and had better adult success. The children who rang the bell quickest were more likely to have received worse teacher and parental evaluations (评价) 10 years later and were more likely to have drug problems at age 32.
The experiments are worth noting because people spend a lot of time thinking about how to improve education, and how to become rich. But when the result is not good, they will come back to ask “How do we get people to get the sort of self-control that leads to success?” This is to enter the world of human nature.
So these experiments, along with everyday experience, tell us that self-control is most important. Young people who can sit through sometimes boring classes to get a degree can work hard in order to learn a language well. They can avoid drugs and alcohol. For people without self-control skills, however, school is a series of failed and painful experience. No wonder they drop out and their later life is a group of foolish ideas, such as drug use, stealing and so on.
【1】The scientist did some experiments to ________.
A. find good ways of training children to learn
B. show that children’s education is important
C. test children’s self-control and later success
D. test children’s intelligence of ringing the bell
【2】What do the underlined words “broke down” probably mean?
A. failed to wait. B. kept waiting.
C. hid the candy. D. ate the candy.
【3】How long did the scientist’s experiments last according to the text?
A. Just 15 minutes. B. Within 10 years.
C. Less than 14 years. D. About 28 years.
【4】What will the children without self-control do at school according to the text?
A. They will improve their education.
B. They will suffer a lot from boring lessons.
C. They will become very rich and successful.
D. They will work hard to catch up with others.
29、 Scientists have discovered a “monster black hole” so massive that, in theory, it shouldn’t exist. It’s a stellar (恒星) black hole — the type that forms after stars die, collapse, and explode. Researchers had previously believed that the size limit was no more than 20 times the mass of our sun because as these stars die, they lose most of their mass through explosions that expel (排出) matter and gas swept away by stellar winds.
This theory has now been toppled by LB-1, the newly discovered black hole. Located about 15,000 light years away, it has a mass 70 times greater than our sun, according to a press release from the Chinese Academy of Sciences.
The findings were published by Chinese researchers in the journal Nature on Wednesday. “Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution,” said Liu Jifeng, head of the team that made the discovery.
“LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation.”
Scientists are now scratching their heads at how LB-1 got so huge.
The Chinese team has proposed a number of theories. LB-1’s sheer size suggests that it “was not formed from the collapse of only one star,” the study said — instead, it could potentially be two smaller black holes orbiting each other.
Another possibility is that it formed from “fallback supernova.” This is when a supernova — the last stage of an exploding star — ejects (排出) material during the explosion, which then falls back into the supernova, creating a black hole.
This fallback formation is theoretically possible, but scientists have never been able to prove or observe it. If this is how LB-1 formed, then we may have “direct evidence for this process” for the first time, the study said.
There are several types of black holes and stellar black holes like LB-1 are on the smaller side, according to NASA. Supermassive black holes are much bigger — they can be billions of times the mass of our sun.
Scientists believe supermassive black holes may be connected to the formation of galaxies, as they often exist at the center of the mass star stems but it is still not clear exactly how, or which form first.
【1】Why does the writer write the article?
A.To report the great achievement Chinese scientists have made in black hole theory.
B.To inform the readers of the basic knowledge about the black hole.
C.To share with the readers the new development of the black hole discovery.
D.To demonstrate the significance of discovering new black holes for science.
【2】What does the underlined word “toppled” mean in the second paragraph?
A.overturned B.supported C.suspected D.tested
【3】Which of the following about LB-1 is true to the passage?
A.It is the biggest black hole ever discovered.
B.It lost only a small part of its mass through explosion.
C.It couldn’t have been formed from the collapse of one star,
D.Its discovery may lead to some breakthrough in the “fallback formation theory”.
【4】Which of the following is right according to the passage?
A.If the sun in our galaxy dies some of its mass will be taken away by stellar winds.
B.A massive supernova will be formed and then exploded if the sun in our galaxy dies.
C.“The Milky Way” was formed after a supermassive black hole collapsed and exploded.
D.If “the Milky Way” dies, a supermassive black hole will be formed after its death.
