答案

参考答案:D

解析: 本题考查涉水渡河的注意事项。水深在0.6m以内、流速不超过3m/s,或者流速虽然较大但水深在0.4m以内时允许徒涉。水深过腰,流速超过4m/s的急流,应采取保护措施涉水过河,禁止独自一人涉水过河。骑牲畜涉水时一般只限于水深0.8m以内,同时应逆流斜上,不应中途停留。

The best way of learning a language is using it. The best way of learning English is talking in English as much as possible. Sometimes you'll get your words mixed up(混合) and people will not understand you. Sometimes people will say things too quickly and you can' t understand them. But if you keep your sense of humor(幽默感),you can always have a good laugh at the mistakes you make. Don't be unhappy if people seem to be laughing at your mistakes. It's better for people to laugh at your mistakes than to be angry with you,because they don't understand what you are saying. The most important thing for learning English is:"Don't be afraid of making mistakes because everyone makes mistakes."
