26、 Earlier research had suggested we're best at learning grammar in early childhood. Then we hit a dead end around age 5. It's supposed to be much harder for older kids. The time when people can learn the rules and structure of a language well appears to last until around age 17 or 18. “But that's not so, ”says psychologist（心理学家）Joshua Hartshorne.
Hartshorne asked friends to take an online English grammar test. After completing the test, volunteers answered questions about where they had lived, the languages they had spoken from birth and the age at which they first started learning English. Hartshorne also asked how long they had lived in an English-speaking country. As he had hoped, people shared the test widely online. This let Hartshorne's group study the answers from 669, 498 native and non-native speakers of English. The researchers used statistics to find out when people with different English-speaking experiences reached their top grammar ability.
If people moved to a new country and began speaking English by age 10 to 12, they finally spoke it as well as folks who had learned both English and another language from birth. But both groups scored a little worse than people who spoke English only, the researchers found. The test results showed that around age 17, people's ability to learn grammar took a sharp drop. And those who started learning English after age 10 or 12 never reached the same level of English skillfulness as people who started younger. Why？The researchers think it's because they had fewer years to practice before their skills dropped off at surprise：Language learning did not end at 17. People's English skills kept improving a little until around age 30, the new study found. And this was true among both native speakers and those who learned English as a second language. Still, most language learning happened by age 20, the new study decided.
【1】What age period is best for grammar learning according to earlier research？
A.From 17 to 20. B.From 5 to 12.
C.Before age 5. D.From 20 to 30.
【2】How did Hartshorne get his study statistics？
A.By experimenting in the lab. B.By making an online survey.
C.By studying historical records. D.By collecting earlier study results.
【3】Which of the following agrees with Hartshorne's study results？
A.Language learning needs much practice.
B.Language learning ends at the age of 17.
C.The more languages you learn, the better.
D.It is best to learn language after 20 years old.
【4】What is the best title for the text？
A.How native speakers learn English？
B.What's the best age to learn a language？
C.What's the best way to learn a foreign language？
D.Why non-native speakers can never master a second language？
27、 Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy (星系).The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world. It was captured by the Event Horizon Telescope (EHT).
The announcement was made in Washington, Brussels, Santiago, Shanghai, Taipei and Tokyo. Details have been published today in Astrophysical Journal Letters.
Prof Heino Falckc, of Radboud University in the Netherlands, who suggested the experiment, told BBC News that the black hole was found in a galaxy called M87. "What we see is larger than the size of our entire Solar System," he said. "It has a mass 6.5 billion times that of the Sun. And it is one of the heaviest black holes that we think exists. It is an absolute monster, the heavyweight champion of black holes in the Universe."
The image shows an intensely bright "ring of fire", as Prof Falckc describes it, surrounding a perfectly circular dark hole. The bright halo is caused by very heated gas falling into the hole. The light is brighter than all the billions of other stars in the galaxy combined - which is why it can be seen at such distance from Earth. The edge of the dark circle at the center is the point at which the gas enters the black hole, which is an object that has such a large gravitational pull (万有引 力）,not even light can escape.
"It is remarkable that the image we observe is so similar to that which we get from our theoretical calculations. So far, it looks like Einstein is correct once again." said Dr Ziri Younsi, of University College London -who is part of the EHT cooperation.
Chinese scientists were involved in the observation through a telescope in Hawaii. They were also highly involved in follow-up data processing and theoretical analysis, said Shen Zhiqiang, head of the Chinese Academy of Sciences' Shanhai Astronomical Observatory and a member of the EHT international team.
Shanghai and Taipei were selected as two of the cities to hold news conferences, together with Washington, Brussels, Santiago and Tokyo, a recognition of China's contribution.
"In the fields of astronomy, radio astronomy, and space astrophysics, China has made a significant contribution to this global project," Falcke said.
【1】What is the best title for the passage?
A.First Image of a Black Hole Taken
B.How Einstein Discovered a Black Hole
C.How a Black Hole Is Formed
D.A Book about Black Holes
【2】Who first got the idea for the project?

【5】What does Dr Ziri Younsi tell us about black holes in Paragraph 5?
A.Black holes can swallow up everything in the Universe.
B.Scientists knew about black holes before they see them.
C.Einstein has been proved wrong many times.
D.Black holes might be some make-up stories.
28、Elephants might be the most well-known and well-loved animal in African wildlife. But conservation (保护) of the African elephant still faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That’s why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.
Years ago, overhunting and the ivory trade were the biggest threats to elephants’ survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.
The 21st century brings a different challenge to elephant conservation—land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.
Successful conservation strategies must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.
AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.
The AWF is helping elephants by protecting their habitats. And they also work with local farmers to improve their life in order to encourage them to protect rather than destroy elephants.
【1】The first paragraph of the text is mainly to tell readers ________.
A．African elephants are endangered now.
B．there remains a lot to do to protect African elephants.
C．African elephants are popular animals.
D．the number of African elephants has increased over the years.
【2】What is the biggest difficulty in protecting African elephants now?
A．They are still being killed.
B．Their habitats are being destroyed.
C．They don’t have enough food.
D．They can’t live in peace with farmers.
【3】To protect elephants, the AWF does all the following EXCEPT ________.
A．feeding elephants
B．protecting elephants’ habitats
C．doing research on elephants
D．helping farmers improve their life
【4】Which is TRUE according to the passage??
A．Overhunting and the ivory trade were the biggest threat to elephants’ survival.
B．AWF scientists are doing researching on farmer.
C．It’s no challenge to protect elephant conservation
D．Now African elephants are safe.
29、 The Children's Groundwater Festival, first organized by the Groundwater Foundation 19 years ago, is celebrated every year in Nebraska, a state of the central United States in the Great Plains. After organizing the festival for 16 years, the foundation passed the program on to the local community of Grand Island, Nebraska. The festival is an annual event for fourth and fifth graders of Nebraska. It is an interesting and energetic day filled with handson education. Water magic, folk singers and musicians, storytellers, and bird shows add to the happy atmosphere during the festival. There are also some educational activities:
Gooey Garbage: Children build a landfill (废物填埋场) and learn how a properlybuilt landfill can protect groundwater.
Water Races: Children learn about water pollution by racing a drop of water through a model.
Well in a Cup: By building a small aquifer (蓄水层) in a cup, children learn about aquifers and drinking water wells.
Taster's Choice: Children drink different types of water, from tap water to bottled water. Then they are taught about the treatment process of each type of water.
There's No New Water: Students are taught to make a special glass container and learn about the water cycle.
The Children's Groundwater Festival not only has a great influence on Nebraska's people. So far, similar festivals have been held in nearly 40 American states, Mexico City, several provinces in Canada, and New Delhi, India. People everywhere are realizing the importance of educating young people to learn and care about groundwater.
