fromtheoperation,Icouldn’tkeepupwithyou.【误区警示】（1）现在分词表示结果时，指自然而然的结果。（2）不定式也可以表示结果，是出乎意料的结果，且多与only或just连用。Hehurriedtothestation,onlytofindthetrainhadleft.他匆忙赶到车站，结果却发现火车已经开走了。[即学即练]

单句语法填空1.Acityistheproductofthehumanhandandmind,________(reflect)

curesb.ofsth.治愈某人的疾病robsb.ofsth.抢某人某物

profit获利[即学即练]

单句语法填空1.Onceheearned

profitbysellingelectricappliances.2.Wetriedtoprofit

ourmistakes.afrom6.[教材原句]Thegovernment,however,doesnotintendtostoptheprotectionprogrammes,sincethethreatstotheTibetanantelopehavenotyetdisappeared.然而，政府并没有打算停止这些保护项目，因为对藏羚羊的威胁依然存在。【归纳拓展】intendtodo/doingsth.打算/想要做某事intendsb.todosth.打算让某人做某事beintendedfor专为准备/设计的【误区警示】hadintendedtodosth.意为“本打算做某事”，表示过去未曾实现的愿望。有这种用法的词还有plan,hope,think,expect,mean等。e.g.Peterhadintendedtotakeajobinbusiness,buthegaveup

tosellforhadintended7.[教材原句]Onlywhenwelearntoexistinharmonywithnaturecanwestopbeingathreattowildlifeandtoourplanet.只有学会和自然和谐相处，我们才不会成为野生生物和地球的威胁。【句式分析】该句中only后接when引导的时间状语从句，此时主句应使用部分倒装。【归纳拓展】“

only+状语（从句）”位于句首引起部分倒装

“only+状语（副词/介词短语/从句）”提至句首以示强调时，后面的句子或主句要用部分倒装，即把助动词、情态动词或be动词提到主语前面。e.g.OnlythendidIrecognize

him.直到那时我才认出他。e.g.Onlyinthiswaycanwecalm

thelittlegirldown.只有用这种方式我们才能让这个小女孩冷静下来。【误区警示】（1）only修饰的状语可以是副词、介词短语，也可以是状语从句。如果only修饰的是状语从句，主句用倒装，从句本身不倒装。Onlywhenheisseriouslyilldoesheeverstayinhospital.只有当他病情严重时他才住院。（2）“only+状语（从句）”如果不放在句首，则不用倒装。Theboywasrescued

onlywhenhisfatherarrivedinahurry.那个男孩在父亲匆忙赶到后才获救。[即学即练]
