水,与我们的生活联系紧密.这些以水为背景的题目不但贴近生活,而且有助于我们节约用水,保护环境的意识.现以中考试题为例说明. 1.数式型 例1 据《2003年宁波市水资源公报》报道,2003年末我市大中型水库蓄水总量仅为293500000m3,比2002年末蓄水总量减少341900000m3,用科学记数法表示2002年末蓄水总量为_______m3. (04年宁波)
Water is closely linked with our lives. These topics with water as their background are not only close to life, but also help us to save water and protect the environment. Now we take the exam questions as an example to illustrate. 1. Numerical model 1 According to "2003 The Ningbo Water Resources Bulletin reported that at the end of 2003, the total storage capacity of large and medium-sized reservoirs in our city was only 29,350,000 m3, which was 34,190,000 m3 less than the total amount of water stored at the end of 2002. The total amount of water storage at the end of 2002 was _______m3 in scientific notation. (Ningbo in 2004)
