1. In sentence fill-ins, always read the whole sentence up to its end, understand the context, and only then address the grammar point at hand. 在做填空题的时候,要记住先通读句子,理解句中情景,然后敲定语法点。
2. There are meant to be substitutes who can fill in for missing colleagues but this means that teaching lacks continuity-and there may not be enough stand-ins to go around. 的确有些老师可以在他们的同事旷课后代课,但这使得教学缺乏连续性——而且代课老师也不够。
