There are about seven ____    students in Grade Eight in Chezhan Middle School.

The first English week at our school started on May 4th, 2010. The whole school was filled with an English learning atmosphere(氛围). A lot of activities were held. There were handwriting activities, story writing, English songs, role playing in English, and so on. All the teachers and students were very happy. They spoke English, sang English songs and enjoyed all the activities.
Handwriting was for the students in lower grades. Although most of them couldn’t write so well, they were all very careful about it. In the show window, there were a lot of colorful handwritten papers. They copied some articles from books or newspapers. And then they decorated（装饰）them with pictures in different colors, and some even put their own photos on them. How cute and lovely they looked!
Story writing was for students in Grade 7 and Grade 8. These students always like cartoons, so they got interested in this activity. Reading the stories they made up, all the visitors couldn’t help speaking highly of them.
The most important event was the English show on the last day. The students and teachers performed a lot of English songs and English operas. Each program won a lot of applause.
One week is not very long, but all the students and teachers learned a lot. Just as the headmaster said, “It is a helpful week. It will certainly lead us to enjoy and learn more from our English studies.”
【小题1】In this passage, the English week is described as__________.

A study finds that not enough morning light causes teenagers not to get enough sleep at night. “As teenagers spend more time indoors, they miss necessary morning light. Day light is needed to keep the balance of the body’s 24-hour biological system (生物系统), which regulates (调节) body temperature and sleep styles,” reports Dr. Mariana Figueiro. “These teenagers who receive little morning light are going to bed later, getting less sleep and doing badly in tests. They are more likely to fail in their exams.”
In the study, Dr. Figueiro asked 11 students in Grade 8 to wear special glasses to prevent blue morning light from reaching their eyes. At the end of the 5-day study she found that they fell asleep 30 minutes later than usual.
Throughout her research, Dr. Figueiro has been very worried about teenagers going to bed too late. The problem is that today’s schools require teenagers to be in school very early in the morning. These students are likely to miss the morning light because they often go to school before the sun is up or as it’s just rising.
Furthermore (此外), the schools are not likely to provide enough electric light to keep the balance of this biological system. Our biological system is much more sensitive (敏感的) to blue light. Therefore, having lots of light in the classroom does not make sure that there is enough light to keep our biological system balanced.
