Project.They represented the usual range：two were close to dropping out before they started the project，while others were honors students.Their guidance teacher was their adviser，consulting with them when the group encountered difficulties.Though they sought advice from English，math and science teachers，they were responsible for monitoring one another’s work and giving one another feedback.There were no grades，but at the end of the term，the students wrote evaluations of their classmates.The students also designed their own course.In addition to some regular courses，they each took on an “individual project”，learning to play the piano or to cook，writing a novel or making a video about domestic (国内的) violence.At the end of the term，they performed their new skills in front of the entire school.The last part of their self-designed course was to do a “collective project” that had social significance.Because they felt the whole experience had been so life-changing，they ended up making a film showing how other students could start and run their own schools.The project was a success.After returning to their traditional study，the students have high motivation and are doing well.One student who had failed all of his previous math courses spent three weeks teaching the others about probability.The lesson learned here is that if students are given the opportunity to take control or contribute significantly to their own learning they will become more accomplished，more engaged and more knowledgeable.The students in the project are remarkable because they demonstrate the kinds of learning and personal growth that are possible when teenagers feel ownership of their high school experience，learn things that matter to them and learn together.1．Which of the following statements is TRUE?A．Some students might drop out of high school.B．The teachers monitored the students’ homework.C．The students themselves solved all their problems.D．The teachers evaluate the students’ performances.2．The students involved in the Independent Project ________.A．didn’t need to learn common lessonsB．tended to escape from the whole societyC．were unwilling to share their experiencesD．focused on self-study and working together3．According to Paragraph 4，we know that ________.A．the traditional study is better than the projectB．all the students had failed their math coursesC．the students have freedom to design their lessonsD．the project was mainly concerned with math courses4．The project made the students outstanding because ________.A．they are unusually talentedB．they have better backgroundsC．they have supportive teachersD．they are owners of their education5．What would be the best title of the text?A．Structure the kids’ days to the minuteB．Let kids rule their own school within a schoolC．Offer students few opportunities to do anythingD．Provide traditional education to the studentsUnit 4Astronomy：the science of the stars课时达标检测Ⅰ.语法和词汇知识1．【解析】选C。
