关于我国土地资源的叙述,正确的是( ) A.土地利用类型齐全,林地所占比重最大 B.耕地主要分布在东部季风区的丘陵地区 C.各地区土地资源的生产力差别很大,东部远大于西部 D.人均耕地面积小,为解决粮食问题可以把草地开垦为耕地 答案:C.6、In cities with rent control, the city government sets
the maximum rent that a landlord can charge for an apartment. Supporters of
rent control argue that it protects people who are living in apartments. Their
rent cannot increase; therefore, they are not in danger of losing their homes.
However, the critics say that after a long time, rent control may have negative
effects. Landlords know that they cannot increase their profits(赢利). Therefore, they invest(投资)in other
businesses where they can increase their profits. They do not invest in new
buildings which would also be rent controlled. As a result, new apartments are
not built. Many people who need apartments cannot find any. According to the
critics, the end result of rent control is a shortage of apartments in the
city.
Some theorists argue that the
minimum wage law can cause problems in the same way. The government sets the
minimum that an employer must pay workers. The minimum helps people who
generally look for unskilled, low paying jobs. However, if the minimum is high,
employers may hire fewer workers. They will replace workers with machinery. The
price, which is the wage that employers must pay, increases. Therefore, other
things being equal, the number of workers that employers want decreases. Thus,
critics claim, an increase in the minimum wage may cause unemployment. Some
poor people may find themselves without jobs instead of with jobs at the
minimum wage.
