完形填空。

                                            eBooks still some way away from students
     Twelve-year-old Tang Yin is one of the earliest students to test a digital textbook in China. The boy said he
was a little   1   when he received the monochromatic (单色的) flat device in April, 2010, because he thought
it should be a "  2   cool" laptop. But Tang still cherishes (珍爱) his new equipment like "protecting my   3 ,"
said the fifth grader. After all, not every student has the opportunity to   4   the eBook, which is worth 2,000
yuan, he said.
     The 50 eBooks,   5   by Taiwan eBook manufacturer Chuanqi Photoelectric Technology in Yangzhou, Jiangsu
Province, enable one class at Yangzhou Sanyuanqiao Elementary School to be the   6   group of students in the
Chinese mainland to replace their regular textbooks with electronic ones. Out of l,000 students, Tang' s class
was the lucky   7  .
     "Our school could not   8   the project without the company' s donation," said Yuan Shishan, vice-headmaster
of the primary school   9   the digital book is considered environmentally friendly, because it replaces paper
books and saves money in the long run, the price is much higher than most Chinese  10  can afford. Also, some
technical defects, the  11  of taking notes and monochromatic display, make the eBook fail to meet the
expectations of students and teachers.
     "There's still a(n)  12  way to go before the eBook really plays an important role in education," said the
headmaster.
     According to Yuan, the annual average income of a  13  family in Yangzhou is about 20,000 to 30,000 yuan,
and neither the parents nor the school can afford the 2,000 yuan  14  book.
     The school doesn't allow the students to take their eBooks to their homes. The devices are  15  after class,
and are locked in the headmaster's office.
