与本课相关的趣味知识及可选用的习题
吃蔬菜的4大好处
好处1 纤维质对人体有益。 蔬菜中的纤维质不能被人体的肠胃所吸收,但本身会吸收大量的水分,来增加粪便形成的软度,有益排便。多吃纤维质可以促进身体的代谢功能,达到控制体重的目的。
好处2 维生素的最佳来源。 蔬菜含有丰富的维生素,其中以维生素C和维生素A最为重要。不过维生素C在烹煮时会大量流失,蔬菜颜色越深绿或深黄,含有的维生素A和维生素C就越多。另外,有一些蔬菜含有丰富的钾、钙、钠、铁质等碱性矿物质,不仅能平稳血液中的酸碱值,也是小朋友生长需要的营养素的重要来源。
好处3 增加饱食感。 蔬菜中的纤维质能增加咀嚼,使饱食感增加,从而减少食物的摄取量,并进而减少热量的摄取。
好处4 整肠健胃,调整体质。 蔬菜中的纤维质能有效促进肠与胃的蠕动,减少食物在肠道停留的时间,减少营养素的吸收并及早协助排出对人体无益的废物。现代人的饮食,摄取加工制品太多,因此更应该多吃蔬菜,健胃整肠,调整血液品质及身体素质。

教学反思
本课主要学习问答句型:What
are
these?Are
they
tomatoes?为了让学生能将所学的语言知识运用好,我设计了“摸一摸”“全班总动员”等活动。在明确的任务目标的驱动下,学生主动参与,对本课的重点句型的理解不断加深,运用起来也越来越得心应手。通过这种活动,学生合作学习的能力与综合运用所学语言知识的能力都得到了提高。此外,学生经过了一段时间的学习,英语有了一定的基础,而且口语也有所提高,这是值得欣慰的地方。不足的地方是,有的学生仍然不能很好地进入学习的状态,对单词和句型掌握得不准确,在今后的教学中,对他们要特别关注。
