Stonehenge,arockcircle,isnotonlyoneofBritain’smostfamoushistoricalplacesbutalsooneofitsgreatestmysteries.巨石阵，一个岩石圈，不仅是英国最著名的历史遗迹之一，而且是英国最神秘的事物之一。notonly…butalso…意为“不但……而且……”，在运用时要遵循以下三个原则：①并列原则：notonly…butalso…并列连词，连接两个并列成分，其中also可以省略。②主谓一致原则：notonly…butalso…连接两个并列主语时，谓语动词在人称和数上要与butalso的主语保持一致。Languagepoints【学以致用】1)不仅是他而且我也对流行音乐感兴趣。____________________________________________2)我不仅感到帮助别人很好，而且我开始把时间用在我喜欢做的事情上。____________________________________________NotonlyhebutalsoIaminterestedinpopmusic.NotonlydoIfeelgoodabouthelpingpeople,butalsoIgettospendtimedoingwhatIlovetodo.③倒装原则：notonly…butalso…连接两个并列分句时，notonly置于句首，表示强调，其引导的句子要用部分倒装，即把谓语动词的一部分(如情态动词、助动词等)放在主语的前面，而butalso后的句子用正常语序。Everyyearitreceivesmorethan750,000visitors.每年它会接待超过75万的参观者。receive及物动词，此句中意为“接待；招待”。receive还可以表示“接到；收到”，与get同义，其后可接介词from。receive和accept区别：receive"收到"，强调客观上收到这一事实，不表明是否愿意接受。accept“接受”，主动地或自愿地接受，带有“满意；同意；认可”等意味，其反义词为refuse【学以致用】1)Laura_________someflowersyesterday,butshedidn’tknowifsheshould________them.2)Dick_________lotsofsupportfromhisparents.3)Everyyearthehotel________guestsfromallovertheworld.receivesreceivedreceivedacceptTheythinkthestonescanpreventillnessandkeeppeoplehealthy.他们认为这些石头可以预防疾病并使人保持健康。prevent作及物动词，可以直接带宾语，表示“阻止，阻挠”的意思；常构成：prevent...from...表示“保护……不受……侵袭”；preventsb.fromdoingsomething.阻止某人做某事，在主动语态中from可以省略，被动语态中不行。同样的表达还有stopsb.(from)doingsth.和keepsb.fromdoingsth.。【学以致用】1)
