wasatemplewhereancientleaderstriedtocommunicatewiththegods.

多年以来，历史学家们认为巨石阵是古代首领用来与神灵沟通的一座神庙。

此句中的whereancientleaderstriedtocommunicatewiththegods是由关系副词引导的一个定语从句，用来修饰名词temple。2.Thelargestoneswereputtogetherinacertainway.这些大块的石头以某种方式被摆放在一起。

inacertainway表示“以某种方式”其中certain表达“某，某一，某个，某些，一些”等意思，仅限于名词之前。

eg：①那位医生只有在特定的日子才在医院里。

Thedoctorisonlyatthishospitaloncertaindays.②图书馆仅在一天的某些时间段开放。

Thelibraryisonlyopenatcertaintimesoftheday.③把某个特定年龄以下的孩子独自留在家中是不对而且危险的。

It’swronganddangeroustoleavechildrenunderacertainagealoneinthehouse.3.Asyouwalkthere,youcanfeeltheenergyfromyourfeetmoveupyourbody.当你走到那儿，你能感觉到一股能量从你的双脚上升到你的身体里。此句中feel是感官动词，其后可接宾语（名词）和不带to的动词不定式充当宾语补足语，用法与see,hear,watch等词一样。

eg：我们感到房子在晃动。

Wefeltthehouseshake.4.短语

notonly…butalso…不仅……而且……

neither…nor…既不……也不……

either…or…

或者……或者……

以上短语是并列连词，可以连接相同的句子成分或并列分句。当连接两个主语时，谓语动词的单，复数形式与其最接近的主语保持一致，即临近原则。

eg：NotonlyyoubutalsohelikesEnglish.

both…and…两者都，既……又……连接两个主语时，谓语动词用复数形式。

eg：BothheandIaregoodstudents.1.有人能解释它为什么在那儿吗？Cananyoneexplain________
