Beijing, together with Zhangjiakou, succeeded in getting the chance to host the 2022 Winter Olympic Games,     1     speeds up the development of Zhangjiakou City. Word came that the Beijing- Zhangjiakou high-speed railway,     2     (locate) in North China, is now     3     construction, and is expected to be completed by 2020 in preparation for the cities to host the 2022 Winter Olympic Games.

Starting from Beijing North Railway Station and heading west through the Great Wall, the project is     4     (probable) the biggest challenge ever. Its designers say that the explosions needed to dig the tunnels will not have     5     negative effect on the structure.

The railway line has a     6     (long) of 174 km as a double-track passage line, with ten stations along its route. Enjoying a total investment of 31.17 billion yuan, the train will travel at an average of 250 km/h，     7     the trip between the two cities will only take 40 minutes.

According to the plan, the high-speed railway will have two branch     8     (line) —   one is to Yanqing Station, the other is to Taizicheng of Chongli, where the Olyimpic village lies. The full railway,     9     (include) a 70-kilometer section through Beijing,     10     (complete) in four and a half years.

A 56-year-old enthusiastic backyard bird watcher named Stuart Dahlquist spent years     1    (leave) out food for a family of crows(乌鸦) and was left     2    (astonish) when he found a gift from them. He first became familiar with the bird family after he rescued two chicks that had come     3     their nest in his front yard five years ago.

Dahlquist had always considered     4     delightful to listen to the baby birds chirp(鸟叫）to their parents during feeding time. When he found the tiny crows     5    (lie) on the ground, he went to help. Despite the squawks of alarm from the adults, Dahlquist managed to pick up the chicks and put them back in the nest. He even left out food and water at the base of the tree in case they fell     6    second time. He then began regularly throwing bird food into his front yard, and the crows     7     (obvious) took notice.

One day Dahlquist was preparing for his daily feeding routine     8     he found a fir sprig （枝）decorated with a soda can tab, which was left in the exact spot       9    he fed the crows. The next day, he     10    (offer) another one and he was amazed by the discovery.

“This isn’t only generous, it’s creative, it’s art," Dahlquist wrote on social media."My mind is blown."

More students than ever before are taking a gap year (间隔年) before going to university. It used to be called the “year off”     1     school and university .The gap-year phenomenon originated (起源) with the months left over to Oxbridge applicants between entrance exams in November and the start of the next academic year.

This year, 25310 students     2     have accepted places in higher education institutions have put off their entry until next year, according to statistics on university entrance     3     (provide) by the University and College Admissions Service (UCAS).

That is a record 14.7% increase     4     the number of students taking a gap year. Tony Higgins from UCAS said that the statistics are good news for everyone in higher education. “Students who take a well-planned year out are more likely to be satisfied with, and complete, their chosen course. Students who take a gap year are often more mature and responsible,” he said.

    5     not everyone is happy. Owain James,     6     president of the National Union of Students (NUS), argued that the increase is evidence of student hardship—young people     7     (force) into earning money before finishing their education. “New students are now aware that they are likely to leave university up to￡15,000 in debt.     8     is not surprising that more and more students are taking a gap year to earn money     9     (support) their study for the degree. NUS statistics show that over 40% of students are forced to work during term time and the figure increases to 90% during vacation     10     (period),” he said.

Ten years ago, Sir Richard Branson launched an exciting challenge. A reward of $25 million would be offered to anyone if he/she     1    (come) up with an achievable and sustainable way to remove greenhouse gases from the air. He thought such an innovation would soon come true, and that    2    (power) people like him would carry out a top-down solution in one fell swoop (一下子).

No such situation appeared, not even with the massive reward. But all is not lost. Branson believed everyone could participate in    3     (save) humanity; it wouldn't be a task for just a few superheroes. It was the spirit    4     inspired Paul Hawken and a network of researchers to come up with the book, Drawdowns.

Drawdown focuses on small, practical steps, not    5    (possible) solutions. Hawken's researchers collected data, information and practical knowledge, creating what is something of an encyclopedia (百科全书) of solutions    6    the climate risk. One section of the book, “Coming Attractions”,     7    (look) at solutions that we are close to getting a handle on, and they are likely to be useful ones for the near future. Not a daydream, in other words,

Just as it says in this book, we can't just build a piece of big equipment    8    (make) the air cleaner. We can make small    9    (contribute) like reducing food waste, changing the lightbulbs to LED, installing solar panels and so on.

We are living in     10    interconnected world, so we need to think about the community, about the common interests of many individuals inhabiting a single planet.

In early December this year, Zhang Guimei was named a national outstanding(杰出的) member of the Communist Party of China for her    1     (devote) to education in rural China.

About 20 years ago, while on the way to visit a student's house, Zhang Guimei, then a teacher in Huaping, Yunnan province, noticed a girl     2    (sit) on the hillside. The girl, 13, told Zhang she was about to get married. It was decided by her parents. "But I want to go to school." the girl said. Zhang went to her house and tried     3     (persuade) her parents to let the girl return to school and promised to pay for the school     4     (fee) herself. However, they didn’t agree.

From then on, Zhang dreamed     5    building a free high school for girls. After years trying to raise money,     6    (final) in 2008, Huaping High School for Girls, a free public high school, was founded at the foot of the Shizi Mountain in Huaping,     7    Zhang is the headmaster. Her efforts have been worth it. Since 2008, more than 18,000 students     8    (admit) to college, which is considered a “miracle” in that distant area.

Zhang plays     9     active part in local education. It is reported that shewill be given(give) the honor of the country's “role model for teachers”in February, 2021. Her     10    (move) stories encourage thousandsof people.
