Unit 4 Lesson 12 Healthy Bones 重难点知识讲解 1.状语从句 (1)so引导结果状语从句，意为“所以，因此”；because引导原因状语从句，意为“因为”。但和中文不同的是，so 和 because 不可同时在一个句子中使用。 例如： Bones help us move freely, so they are important. 骨骼帮助我们自由地移动，所以它们很重要。 I didn't plan the work well, so I didn't finish it on time. 我没有好好计划工作，所以我没有按时完成。 Bones are important because they help us move freely. 骨骼很重要，因为它们帮助我们自由地移动。 He went to bed because he felt ill. 他上床睡觉了，因为他生病了。 (2)although 引导让步状语从句，意为“虽然”，但不能和 but 同时在一个句子中使用。例如： Although bones are hard on the outside, they are soft on the inside. =Bones are hard on the outside, but they're soft on the inside. 虽然骨骼外表坚硬，但是它们里面很柔软。 Although it rained, we enjoyed our holiday. 尽管下雨了，我们仍然愉快地度过了假期。 2. 反义词记忆 我们可以将互为反义词的形容词成组记忆。在日常的学习中，也要有意识地总结已学过的互为反义词的形容词。 例如：sick—healthy，weak—strong, tall—short, fast—slow 3. ...bones are strong enough to support our weight.（…骨骼很结实，足够支撑我们的体重。 【解析】sb./sth+be动词+形容词+enough to do，表示“某人/某物足够…可以做某事”。例如： He is old enough to decide by himself. 他足够大了，能自己做决定。 The policeman was fast enough to catch the thief. 这位警察足够快，能够抓住这个小偷。 一、短语互译。 1. on the inside______________ 2. carry nutrients_______________ 3. the soft part_______________ 4. waste materials_______________ 5. make it a habit_____________ 6. 支撑我们的身体____________ 7.自由地移动_______________ 8. 将⋯⋯移走__________________ 9. 使骨骼坚固______________ 10. 有更健康的骨骼___________ 11. 日常活动__________________ 二、用括号内所给词的正确形式填空。 1.
