答案　B

解析　细节理解题。根据"Students who are successful in an on­line course are usually...capable of working independently..."可知，学生需要独立完成作业，与B项相符。

Step Two　信息句与长难句分析

1．(1题信息句)Benefits of e­Learning

Include：access to courses that may not be available at his or her TDSB school.

翻译　在线学习的好处包含：可以接触到他或她在TDSB学校无法接触到的课程。

分析：关系代词that引导定语从句，修饰先行词courses。

2．(2题信息句)Students who are successful in an on­line course are usually：able to plan，organize time and complete assignments and activities；capable of working independently in a responsible and honest manner；and，able to regularly use a computer or mobile device with Internet access.

翻译：在线课程学习优秀的学生通常能够规划，利用好时间并且能够完成任务和活动；能够以负责的心态和诚实的态度独立工作；能够定期地使用计算机和移动设备上网。

分析：who are successful in an on­line course是一个定语从句，修饰先行词students；三个形容词短语able to...，capable of...，able to...作并列表语。

3．Students need to spend at least as much time with their on­line course work as they would in a face­to­face classroom course.

翻译：学生们需要花至少和他们上传统课程一样的时间来完成在线课程。

分析：本句含有由两个as构成"as＋adj.＋a(n)＋n.＋as..."(与......一样)的句型。一般来讲，形容词、副词原级的比较结构为"...(not) as (so)＋adj./adv.＋ as..."，表示前者与后者一样/不一样。如果中间有名词，要把冠词和名词放在形容词的后面，构成"...as＋adj.＋a(n)＋n.＋as..."的结构。
