My uncle set up a small business in our city four years ago. He is known as using iron from old cars to make beautifully art pieces. Last summer vacation, I visit him and he showed to me many of his works. Some are larger pieces looked like animals and humans, and others are smaller pieces you can put at home. He often encourages me to be creative like himself. The art tells people the important of environmental protection. What’s more, it shows that even irons can be brought back to life with little creativity.

“Leave a place better than you found it.” is a simple philosophy that I hold dear. I led 20 volunteers to help clean up the Great Wall in April. Tile Great Wall is one of the 1. (great)structures in the world. Everyone has a responsibility to protect it.
I first went to China to visit the Great Wall in 1986. Since 1990, I 2. (stay)in China with my family, 3. (spend)more than 2,700 days on the Great Wall. I have written several books on the subject, and also fronted documentaries.
I am credited with arousing China’s 4. (nation) consciousness to protect the Great Wall and its environment and I have held several exhibitions. 5. (protect) the Great Wall and assume the role 6. its international ambassador, I got permanent residency（居住权） in China. I live in a village below the Great Wall.
It’s a good thing that people are going out to enjoy 7. (they) and to discover tire great heritage and history, but 8. is also quite dangerous if they don’t understand 9. fragile the environment is. Every person can make a 10. (different). If we can get everybody to protect the environment, the world will be more green, beautiful and healthy.
Last week, a thing occurred in the classroom of a 4th-grade at Chino Valley Unified School.
It was Autism ( 自闭症) Awareness Month and every ________ had been asked to have each student ______ a paper puzzle piece and hang it on their classroom doors. When Ms. Lisa Moe____ the puzzle pieces, most of her students were familiar with the ______ of autism and they were ____ of the reason for doing so. However, they did not know autism was ________ within their own classroom in their _____ classmate: Jackie.
With ______ , Jackie raised his hand and said, “May I please say something?” Moe nodded but never could she have imagined what was to _____.
She explained in a blog post: “Jackie has ______ challenges and barriers beyond what any of us will ever be able to fully _______ . But today, he stood in the front of the classroom with full _____ and showed us that no challenge or barrier can ________. He brought to life the meaning of “Yes, I Can!”
Both the teacher and students were hanging on his every word. For a(n)______ time, Moe never thought of getting out her phone to ______ this moment, but finally she ______ it. Without any of the students knowing, she recorded the ______ moments of Jackie’s, along with the ______ of the other students as they raised their hands to ask questions.

Vitamin D is necessary for bone-building, immune function, blood sugar control, positive mood and more. 1. The lower your vitamin D level is, the higher your risk of death from ally cause will be. However, it’s not a great idea to just take a supplement (补品) off the drugstore shelf and start taking it.
Since many of us have an inadequate amount vitamin D, also known as the “sunshine vitamin”, doctors will often give us high levels of D supplements, with doses ranging from 2,000 to 10,000 IU (International Units) per day, up to 50,000 IU per week and sometimes even more. 2. Very big doses ( 剂量) of vitamin D can cause a build-up of calcium ( 钙) in the blood, which leads to poor appetite, weakness, weight loss or other diseases. Here’s the bigger issue: 3. A build-up of stored vitamin D cart cause avoidable problems, leading to problems such as kidney stones.
4. The National Institutes of Health set the Recommended Dietary Allowance for vitamin D at 600 IU daily for babies, children, and adults up to 70 years old. Adults aged 71 and older need 800 IU, since the ability to absorb vitamin D drops with age. Because the fat cells take vitamin D up, making it less available for use by tile body, 5.
Though you’ll get a bit of vitamin D from foods—including fatty fish, beef liver, cheese, milk and so on—the amounts are so small that there’s little need to worry that they’ll put you over the daily dose.
A.It can help prevent many diseases.
B.We can actually reduce the risk of death.
C.people who are fat may also need more vitamin
D.any extra intake of vitamin D can get stored in the body.
E.But like all good things, it’s possible to get too much of it.
F.The average daily recommended amounts vary based on your age.
G.Vitamin D should be supplemented carefully despite its importance.
A global group of scientists have reduced the time it takes to find and introduce disease-resistance genes from wild plants into domestic crops such as rice, wheat and potato, a research revealed on Tuesday.
Scientists from the John Innes Center in Britain, along with colleagues from Australia and the United States, have created a database known as AgRenSeq, where researchers can easily search for resistance genes already discovered in wild relatives of modern crops.
The study was co-authored by a global expert Professor HarbansBariana from the University of Sydney, who said that this technology will support the discovery and characterization of new sources of disease resistance in plants. Once researchers have identified resistance genes using AgRenSeq, they can clone them and introduce them to domestic crops to protect against diseases and pests,
“We have found a way to scan the genome(基因组)of a wild relative of a crop plant and pick out the resistance genes we need and we can do it in record time,” Dr. Brande Wulff, a project leader from the John Innes Centre, said.
“This used to be a process that took l0 Or 15 years and was like searching for a needle in a haystack(干草堆),” Wulff said. “We have perfected the method so that we can clone these genes in a matter of months and for just thousands of dollars instead of millions.”
The team are highly optimistic about their work, predicting it to be utilized in protecting many crops with wild relatives including soybeans, pea, cotton, potato, wheat, rice, banana and cocoa. “Using speed cloning and speed breeding we could deliver resistance genes into the best varieties within a couple of years, like a phoenix(凤凰) rising from the ashes,” Wulff added.
1.How have the researchers developed the resistance genes?
A.By reducing the research time.
B.By introducing them to wild plants.
C.By cloning them from domestic crops.
D.By getting resistance genes from wild plants.
2.What will be the use of the study in the future?
A.It will protect crops from being damaged by pests.
B.It will create a database for researchers to search.
C.It will protect domestic crops for 10 to 15 years.
D.It will contribute to reducing the wild plants.
3.Which of the following best explains “utilized” underlined in Paragraph 6?
A.Produced. B.Made.
C.Used. D.Studied.
4.What can we infer from what Brande Wulff said?
A.The resistance genes cost millions of dollars.
B.The resistance genes were found in a haystack.
C.It took the researchers ten years to find the resistance genes.
D.Disease-resistance genes will be put into practice soon.
