hedging 关于语法的,怎么解释?我要将一节课英语是关于language reference : hedging .
Hedging 显然是动词 hedge的动名词或现在分词,因此应该从动词说起.
1、动词 hedge 本意表示“用树篱之类的东西把…围起来使之被隔离或受到保护” ,引申义是“(赌博)两面下注、(在交易所)做套头交易、推诿或说话做事留余地”.例如:
◎ John hedged his bets for the purpose of hedging against loss.约翰为了免受损失而两面下注.
◎ It is hedging its bets in the all-important diplomatic poker game.在这场十分重要的外交赌博中,它在两方面都下了赌注.
◎ You are hedging again ; have you or have not you got the money .你又在闪烁其词,你到底有没有钱.
2、hedging 常用作动名词,表示“规避、躲闪、限制、闪烁其词”等的行为.例如:
◎ Stop hedging and answer my question!不要规避,快回答我的问题!
◎ People are happy because they have succeeded in hedging the king in.人民非常高兴,因为他们成功地限制了国王的权力.
3、期货专业术语中,hedging表示套头交易、对冲买卖或套期保值(即在期货市场上买入(或卖出)与现货市场交易方向相反、数量相等的同种商品的期货合约,进而无论现货供应市场价格怎样波动,最终都能取得在一个市场上亏损的同时在另一个市场盈利的结果,并且亏损额与盈利额大致相等,从而达到规避风险的目的)的行为.例如:
◎ Such bet-hedging is sensible.这种两面下注的方法是合理的.
◎ This is called hedging slippage.这种情况被称为对冲打滑.
◎ The effectiveness of hedging can be reliably measured.套期有效性能够可靠地计量.
◎ Hedging in futures markets is synonymous with shifting risk.期货市场上的套做交易实际上就是转移风险.
◎ Hedging in futures markets in synonymous with shifting risk.期货市场上的套期保值交易实际上就是转移风险.
再问: 我要的是语法,不是解释hedging是什么意思?
再答: 我在词法分析中已经部分涉及到了 hedging 的如下的语法问题: 1、hedging 是动词 hedge 的动名词(the word “hedging” is a gerund form the verb “hedge”)。 2、作为动名词,它有以下的语法功能(as a gerund, it can be used in a sentence as follows): a) 主语(subject “hedging” with verbs), e.g.: ◎ Such bet-hedging is sensible. 这种两面下注的方法是合理的。(hedging with link verb be) ◎ Hedging in futures markets is synonymous with shifting risk. 期货市场上的套做交易实际上就是转移风险。(“Hedging” with link verb be) ◎ Hedging in futures markets should be carried out to shift risk. 为转移风险应该运作期货市场上的套头交易。 (“hedging” with the passive voice) b) 宾语(object “hedging” following transitive verb or preposition) ◎ They should carry out hedging in futures markets to shift risk. 我们应该在期货市场上运作套期保值以转移风险。 c) 表语(predicative “hedging” following a link verb) —— 例句略(examples omitted) d) 定语(attributive “hedging” with noun phrases) : ◎前置定语 (prepositive attributive: “hedging” modifies a noun phrase before it) ——例句略 (examples omitted) ◎后置定语 (postpositive attributive: “hedging” modifies a noun phrase after it) ——例句略 (examples omitted)
再问: 虽然不是我确确要的答案,不过,辛苦你了。
