But usually people would accept tame(温顺的) and loyal(忠诚的) animals as pets rather than dangerous ones such as a lion，a tiger or a snake.People love pets and take good care of them. The owners usually regard pets as good friends and some even consider them as members of the family. Although they are not human beings(人类), their behavior sometimes is better than human beings, for they are always loyal to their owners. There are always many stories about brave and smart pets. We often hear that a pet dog saved the owner's life or traveled thousands of miles to return home. Such stories often make pets more lovely.Some pets can also be trained to help people with some special work. For example, trained dogs can help the blind to walk and trained dogs and pigs can even help police to find where drugs are easily.But pets are sometimes trouble-makers. Some pets like dogs or snakes may hurt people without any warning. Some people may become ill after being hurt because of the virus carried by the pets. If they are not taken good care of, they will become very dirty and easily get ill. So pets are helpful to us but keeping pets is not an easy job.51.

（1）已知红热的铜丝能在氯气中燃烧，推测红热的铁丝也能在氯气中燃烧。
（2）已知铁粉和硫粉加热条件下能发生反应，推测铜粉和硫粉在相同加热条件下也一定能发生反应。
（3）从二氧化硫通入Ba(OH)2溶液能产生白色沉淀的事实，推测二氧化硫通入BaCl2溶液也能产生白色沉淀。
7、为了测定不同电解质的水溶液的导电能力是否相同，设计如下图所示的实验，请回答下列问题：（1）本实验取了盐酸、CH3COOH溶液、NaOH溶液、NaCl溶液和氨水五种溶液，若要再增加一种溶液，你认为选取下列哪种溶液最为合适？（A）硫酸钠（B）硝酸钙（C）氢氧化钡（D）氯化钾（2）为了排除无关因素的干扰，本实验应控制多种实验条件，如烧杯的规格相同、烧杯内溶液的体积相等、相同的电极材料、各电极间的距离相等、溶液的温度相同、灯泡的功率相同等，除此外，你认为还应控制的最关键的条件（或因素）是。
（3）本实验通过观察到现象，间接说明不同电解质溶液导电能力是不同的。
（4）通过本实验，证实了在相同的条件下，不同的电解质溶液导电能力是不同的，从而可直接推出的结论是。
