问题 单项选择题

期货交易主要是以( )为保障,从而保证到期兑现。

A.行业规则
B.法律制度
C.保证金制度
D.市场制度

答案

参考答案:C

解析: 期货交易具有高信用的特征,这种高信用特征集中表现为期货交易的保证金制度。期货交易需要交纳一定的保证金。交易者在进入期货市场开始交易前,必须按照交易所的有关规定交纳一定的履约保证金,并应在交易过程中维持一个最低保证金水平,以便为所买卖的期货合约提供一种保证。保证金制度的实施,不仅使期货交易具有“以小搏大”的杠杆原理,吸引众多交易者参与,而且使得结算为交易所内达成并经结算后的交易提供履约担保,确保交易者能够履约。

     "What would you do if you were the mayor (市长) of your city?" We asked some students from different

cities. Here's what they said:

Deng Chuan,15, from Dazhou

     With the development of modern industry (工业), more and more waste water is being poured into the

Zhouhe River, It has caused serious pollution. The river is becoming so dirty that few living things can live

in it. So, if I were the mayor, I would order all the factories that pour the waste water into the river to close

down. As we all know, water is the source (根源) of our lives. It is very important to protect water.

Zhang Yan,14,from Chengdu 

     Our city is more and more beautiful. But sometimes it's not convenient for the blind. There are not enough

pavements (人行道) in our city. Some of the old ones are broken. They may not be safe to walk on! If I were

the mayor of our city, I would build more pavements for the blind.

Wang Lili, 16,from Chongqing

     There are more and more old people in our city. And there are not enough places for them to relax and

enjoy themselves. So, if I were the mayor, I would build an activity center in each residential (住宅) area for

the old. So old people can play cards or chess. This will make old people not feel lonely any more and spend

remaining years comfortably.
