AUnsolved Mysteries About Planet Earth♦Mystery 1 ： Where did all the water come from?Water covers 70 percent of Eart h’s surface and earns it the nickname “the blue planet”. And where did it come from? The most popular scientific theory states that the H2() arrived in the form of several violent asteroids (小打星〉filled with ice. Another suggests that the water actually has been around since Earth's formatioa However it happened, though, it ^certainly worked out well for Earth’s life forms.♦Mystery 2 ： What about all the oxygen?Another thing is the planet s oxygen. Tiny creatures released oxygen as a waste product, filling the atmosphere with it After that, the level of oxygen in Earth’s atmosphere went wildly up and down until it finally calmed down around 540 million years ago. Since then, it's remained at about the breathable level we experience today. But what caused it to be suddenly steady?♦Mystery 3： What caused the Cambrian (寒武纪）Explosion?The Cambrian Explosion refers to the explosion of complex life that occurred on the Earth about 540 million years ago. Before then，life had consisted mostly of bacteria. But at the be-ginning of the Cambrian period, complex creatures began developing at a rate never before seen* Suddenly» life forms had brains» eyes, and bones. Most creatures alive today can trace their blood back to the Cambrian period♦Mystery 4： Will we ever be able to predict earthquakes?We still haven't been able to come up with a way to accurately predict earthquakes. We can certainly try, but our current technology cannot predict them exactly. We know that earthquakesstart when rocks crack underground and send earthquake waves toward the sur- face，but we haven’t figured out why that happens，or how to predict it.21. What was created later by creatures on the Earth?A.Water.B.Oxygen.C. Bacteria.D. Ice.22. Which of the following tal ks about the Earth’s advanced species?A. Mystery 1.B. Mystery 2.C. Mystery 3.D.

Yet, while this image has become an unforgettable part of our pop cul- ture，few people knew that the same sort of response applied to service dogs.Once a blind man fell flat on his face, which was awful but finally harmless. His service dog，however, was trained to get an adult if the owner had a seizure (癒痫），and it was sure this was a seizure. However, while the dog did what it was taught, the woman it found was merely annoyed but not alarmed. Thankfully* the dog’s owner was not in the situation of a medical emergency. However, the experience inspired him to share this information on social media，“If a service dog without a person approaches you, it means the person is down and in need of help，” the owner explained “Don’t get scared, don't get annoyed, follow the dog! If the first person doesn’t cooperate, it moves on. ”Referring to the accident, a TV presenter asked a dog trainer, Olivia, some basic questions about service dog etiquette (规矩），including how humans should react if an unaccompanied service dog should approach them.“What the/re going to do is take their nose and gently push your leg,” the trainer ex plained, specifically noting that service dogs are not usually trained to jump or bark, “If you see adog in vest without a person attached to it, follow it. ” When asked if one should say something to ind icate theyVe prepared to follow the dog, Olivia said there’s no clear command. “The spoken language is not going to be a secret password,” she said. “You can say, ‘What?’ or ‘Where?’ or just start walking wherever the dog leads. ”Olivia concluded the TV show by adding that those who rely on service dogs CAn train their companion to move along to someone else，should the first person they come upon react negatively to the dog’s request. Doing so could finally save the owner’s life.24. What do we know about service dogs?A. They can’t understand others' spoken language.B. They are seldom known by most people.C. They often make people annoyedD.They only exist in the pop culture.25. In the owner’s emergency, a service dog will generall .A. ask the nearby person for helpB. run home for help from familiesC. jump or bark to draw humans' noticeD. stay beside the owner until he or she recovers26. How should people react to a separate service dog?A.Take it to the nearest police station.B. Communicate with it through commands.C. Keep it home until finding its owner.D. Follow it to anywhere it leads.27.What is the author s purpose of sharing the story?A. To encourage everyone to help disabled people.B. To introduce a talk show about service dogs.C. To spread knowledge of dealing with service dogs.D.To teach how to train service dogs well.CA child s early years of language development are important for the basics of school readi- growth. In a recent study, Perry and a team of fellowness, such as literacy (读写）skills and social and emotional University of Miami Assistant Professor of Psychology Lynn researchers who examined child speech communications over the course of a year found that children benefit from conversations with their peers (同龄人）and their teachers. The study examined how language use and development in 2-and 3-yearold children was influenced by what they heard from their teachers and their peers.“Previous research on language development looked mostly at the role of parent-child communication within a home setting or a lab environment, which means we’re missing a big part of a child’s everyday lif e-the classroom，” said Perry. “We know that parent language is important for children’s development and their academic achievement, but we don’t have much research on what happens in the kindergarten or preschool setting. ”Using a device (设备) called a language Environment Analysis (LENA) recorder, Perry collected hundreds of hours of audio recordings. Children wore the LENA recorder once a week. LENA then assessed whether the recorded audio was speech or not, andwhether the speech came from the child wearing the recorder or from an adult or another child talking to them.After studying the audio data, Perry found that the speech children heard from other chil-dren was positively related to their own language use, meaning children who heard the most from their peers learn more new words and vocalize more during the course of the year. Addi- tionally，there was a positive association between a teacher talking and children's language use and development—but only when that teacher talked to the child in a back-and-forth conversation, rather ,han iust talking to the child with no opportunity for the child to respond.“One importan t aspect of the study that stands out to me is how important it was to see those conversational turns with teachers, and that back-and-forth conversation with the child is very beneficial. We talked to the teachers about the results, and they are very excited about this finding and currently brainstorming additional opportunities to have conversations with children," adds Perry.28.What does the new study focus on?A.The basics of school readiness for preschool children.B.The parent-child communication at home or in the lab.C. The influence of talking in the kindergarten on children.D. The ways to improve preschool childrens healthy growth.29.How did the researchers perform their new study?A. By observing the children in class.B. By recording the child ren’s speech in class,C. By communicating with the children.D. By conducting a survey of teachers.30.

But many orgdnisms there produce poisonous chemicals to hunt Divers are now collecting such poisons as drugs for human medicine.Sharks aren’t the scariest things in the ocean for scientists who dive to work. Powerful currents, creating where the ocean floor drops away, can be just as deadly. But the scientists who work underwater train to deal with these dangers. The rewards of research and underwa-ter adventure are greater than the risks.The sea may seem like a strange place to look for new drugs. But organisms in the ocean have had to adapt to a tough environment. The chemicals they make for survival might help people* too. More than 50 years ago，scientists discovered a new anti-cancer drug in a sea sponge. Since then, researchers have been hunting the seas for more of such useful natural products.With the help of underwater robots and small submarines, scientists are searching the seas—from shallow reefs to the oceans' great depths.Bacteria living in the Arctic's cold waters break down their food using more different ways than organisms on land do. This process of turning food into energy for growth, activities and reproduction is called metabolism (新陈代谢）.These pathways also produce chemicals called “secondary metabolites”. One day they also might help people.During a four-year project called Pharma Seas, scientists made thousands of extracts (提取物）from those seafloor samples. In about a dozen of them，researchers found mixtures that can kill bacteria t hat some of today’s antibiotics (抗生素）cannot. Three other newfound chemicals reduce epileptic seizures (electrical storms in the brain) in mice. Yet another compound may reduce the symptoms of Alzheimer’s disease.32. Why do sea organisms produce chemicals?A.To struggle for survival.B.To benefit other creatures.C.To change their environment.D.To warn themselves in the sea.33.In whnt way does Arctic bacteria differ from organisms on land according to the text?A. Medicinal value.B.The way of hunting.C. Importance to humans.D.The way of breaking down food34. What is special about the mixtures from seafloor samples?A. They have the same effects as today’s medicine.B.They can treat most diseases.C.They have unique functions.D. They can kill all bacteria.35. What can be a suitable title for the text?A. Threats from the OceanB.Diving for New Medicines.C. Future Sources of BacteriaD. Danger of Diving in the Sea第二节（共5小题;每小题2分，满分10分）根据短文内容,从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。
