3Pollutedwaterlessenscropyields.4Hisbusinessyieldsverybigprofits.

那位英勇的军人宁死也不肯屈服于这样的敌人。这座矿已生产了3714吨煤。受污染的水源会降低农作物产量。他的企业获利很大。翻译下列句子Today,itisestimatedthatabout60percentofdomesticriceconsumptioninChinaiscomprisedofcropsgeneratedfromYuan’shybridstrains,andhisstrainshaveallowedChina’sfarmerstoproducearound200milliontonsofriceperyear.句意：据估算，现在中国国内消费的稻米有大约60%来自袁隆平的杂交水稻品种形成的作物，这些品种（形成的作物）让中国农民每年能够生产出大约两亿吨稻米。此句的真正主语是从句thatabout60...peryear。因为真正的主语太长，为了避免句子头重脚轻，所以用形式主语it。英语中还有许多类似Itisestimatedthat...

这样的结构，用来将真正主语后置。如：Itissaid/believed/reportedthat...domestic

可用作介词，表示“只要是；考虑到；假定；已知”等意思。farfromthecase

远非如此，也可以说farfrombeingthecase。其中，case表示“情况；情形”。farfromsth

远远不；绝非例2：Givenhisage,heisverystrongandhealthy.

考虑到他的年龄，他可以说是非常健康强壮了。Deepdown,Yuanisstillverymuchafarmeratheart.
