一篇英语文章，帮忙翻一下吧。

[二]Educational pressure rises for Chinese children

It was Saturday afternoon. The “darkest moment” was coming for 11-year-old Xu Xiangyu. At 6 pm, Xu was sitting with other children of his age in a classroom of Beijing. He was given a list of 16 math problems. He was asked to solve them in one hour.

But Xu didn’t. In the following hour, he sat silently, listening to a class about the answers to those difficult math problems. Now and then, he could feel his mother’s watchful eyes looking at him from several rows behind.

His mother was taking notes. So were other parents and grandparents, who were listening to the class with their children.

Xu was attending the “Olympic math class” which focuses on math that is far above the level of primary school. Such after-school classes, along with others which focus on English or Chinese literacy, are here and there across China.

“Almost all the kids in his class are attending such classes,” Xu’s mother said. “I am afraid he would not catch up with others if he didn’t. The competition for a good middle school is so hard.”

China’s nine-year compulsory education covers primary and secondary school. No entrance（入学）tests are necessary for the students to enter public middle schools, according to the law.

But in fact, if a student is good at math or English or has some special music or sports talent（才华）, it is easier for him or her to study in a top middle school.

The nine-year compulsory education aims to provide equal（平等的）educational chances for every child. However, competition for good middle schools has increased Chinese children’s burden（负担）, harmed their health and made inequality in education.

Childhood in China is becoming an unhappy time. A lot of surveys have showed that China’s primary and secondary school pupils are slaves to homework and after-school classes. They don’t have enough sleep time or sports time.

Xu spent one year in a London primary school from 2007 to 2008 when his mother studied there. Xu said that he missed his school in Britain, where he found all the classes interesting and his only after-school class was football. “I miss the school, too. At least I was more relaxed and confident there.”

以上。拜托了！！谢谢。

一个星期六的下午。对十一岁的徐翔宇来说是灰暗的时刻。下午六点，徐翔宇和他同龄的孩子一起坐在北京的一间教室里。他被请求在一小时内完成16数学问题。

但是徐翔宇没有完成，在接下来的时间，他静静地坐着，听着关于这些困难的数学问题的答案。时不时的，他可以感受到他母亲从后面几排看着他。

他的母亲在记笔记。因此，一些其他的父母和祖父母同样也在记笔记。

徐翔宇参加的“奥林匹克数学班”，着重于数学，其远远高于小学水平。这些课后培训班，与一些英文或中文的培训班一样，在中国遍地开花。

“几乎所有在他的班上同学都参加这样的培训班，”徐翔宇的母亲说。 “我怕他会落后，如果他不上培训班。因为进一所好的中学非常困难。”

中国的九年制义务教育包括小学和中学。入学考试对学生要进入好的公立中学非常重要，虽然法律上没有明确的规定。

但事实上，如果一个学生擅长数学，英语或是有一些特殊的音乐或体育才能，对这样的学生来说，更容易进入一流中学读书。

9年义务教育的目标是为每一个儿童的提供平等教育机会。然而，对一流中学的竞争增加了中国儿童的负担，不利于他们的健康，从教育上看也不公平。

童年时光对于中国的孩子们来说并不快乐。很很多调查表明，中国的小学和中学的学生，成为了家庭作业和各类补习班的奴隶。他们没有足够的睡眠时间或运动时间。

从2007年到2008年当他的母亲在那里学习时 ，徐翔宇在伦敦的小学学习了一年。徐翔宇说，他怀念在英国的学校，在那里他觉得所有的课程都非常有趣，他课后要上的课也只是踢足球。 “我想念学校。至少我在那里更轻松和更自信。”
