If you want to travel from Xi'an to Chengdu by train, it will take about 16 hours. But starting this month, the new Xi'an-Chengdu high-speed railway will shorten this travel time to three hours.
The 643-kilometer line is China's first high-speed railway to run through the Qinling
Mountains, which form a natural boundary(·Ö½çÏß) between China's north and south. With a speed of 250 km per hour, it's also the first mountain-heavy train line to provide a 4G network.
Along the way, the train passes through two areas for rare(Ï¡ÓÐ) wild animals ¡ª one for pandas and the other for crested ibises(Öìûq).
To reduce the railway's influence on the animals, workers and experts have designed and built the railway to be environmentally friendly, China Daily reported.
In September, there were 345 wild pandas living in the Qinling Mountains. China now has l,864 wild pandas in total, according to the Xinhua News Agency.
To avoid disturbing the pandas, the railway was designed to run through tunnels(ËíµÀ)
within the area. Protective shields(·À»¤ÆÁ) are placed near the entrance of each tunnel to stop animals from going in.
To avoid hurting the thousands of crested ibises that fly near one part of the railway, protective nets have been set up along the tracks to make sure the birds will not fly into a train.
The nets are about 32 km long and 4 meters high. Experts tested different shapes and materials for building the nets before making their final choice.(A report in December, 2017)

On Monday, I stopped my car in front of my daughter Juliet's middle school. She jumped in
the front seat, feeling down. She asked me to help her study for her science test.
¡°Dad I need to memorize a unit about the Reproductive Cycle of Plants. And I can hardly make it.¡±
"You know memorizing seems like the best way to study, but in fact you can do better in tests if you work on trying to understand the material.¡±
Juliet was open to my advice. It was Monday afternoon and we had two nights to study before the test on Wednesday. I suggested a plan. "Tomorrow night, you are going to teach the material to me. Tonight, read the unit. Prepare to teach.¡±
Asking her to teach me was an unusual idea but I was determined to do it. Studies show teaching somebody else is a very useful way to lean, Even if you don't do the teaching. the act of preparing to teach leads to more learning than just trying your best to memorize the material.
On Tuesday afternoon, Juliet sat down with her Science book facing me said, ¡°Okay Dad, let¡¯s study.¡± I wanted her to teach me. But false starts happened. I couldn¡¯t be too hard on her. So instead we starred with me asking her some simple questions. She knew some but not other. When she didn't know the answers. I encouraged her to check the book.
She started checking things that didn't make sense. And she was actively seeking to test her understanding. I was happy to see it. She wasn't memorizing, she was trying to make sense of things, which was exactly what I had hoped she would do.
1.Why did Juliet feel down?
A. Because she failed her science test.
B. Because she had trouble memorizing a unit.
C. Because she knew nothing about planting.
D. Because she couldn't follow her teacher.
2.In the writer¡¯s opinion, which was the key to best learning?
A. Memorizing
B. Testing
C. Questioning.
D. Understanding
3.The underlined word "it" in paragraph 5 refers to ¡° ¡°.
A. making her check the book
B. using simple questions to test her
C. encouraging her to read the unit
D. asking her to teach me the unit
4.When false starts happened, the writer was .
A. patient
B. worried
C. nervous
D. embarrassed
5.Which can be the best title for the passage?
