下列对电子数字式计算机工作电路的说法哪一个是不正确的（ ）。
①
数字式电路中信息载体往往采用的是电的某一方面的属性，比如电平高低范围
②
数字式电路中的开关元件不具备信息存储功能，所以往往要将电信号转换为其它比如磁信号进行信息存储

阅读理解：阅读下列短文，回答文后问题，选择最佳答案Trees mainly serve man in three important ways: They provide him with wood and other products; they provide him shade; and they help to prevent droughts and floods.Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important．In his eagerness to make money from trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And besides, he is usually too careless to plant and look after new trees. So the forests slowly disappear.This does not only mean that man will have fewer trees. The results are even more serious: for where there are trees, their roots break up soil allowing the rain to sink in and also bind(固定) the soil, thus preventing it from being washed away easily；but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When the top-soil is gone, nothing remains but worthless desert.Two thousand years ago，a rich and powerful country cut down its trees to build warships, with which to gain itself an empire．It set up the empire, but, without its trees, its soil became poor and grew weak. When the empire fell to pieces, the home country found itself faced by floods and starvation(饥荒)．4. Why did the country mentioned in the passage suffer from floods and starvations?
①
A. Because it set up an empire.
②
B. Because it fell to pieces.
③
C. Because it turned its trees into warships.
④
D. Because it spent too much money on wars.
