hundredsofpeople复数形式表概数，“数以......计的”与of连用，作名词的修饰语，其后面的名词必然是复数形式。4.toseeourtownandtowalkthroughthewoods.来参观我们的小镇并在树林中散步。不定式短语作目的状语。由and连接的两个动词不定式。介词through，“穿过”，强调纵深向，如：walkthroughtheforest：而across强调横向，如：walkacrossthestreet5．visitorshavebeenaskedtokeepthewoodscleanandtidy．游客已被告知要保持树林的整洁。现在完成时的被动语态，说明需求的行为应为游客所知。tokeepthewoodscleanandtidy是动词不定式短语，作主语visitors的补足语。cleanandtidy是宾语thewoods的宾语补足语。

cleanandtidy“整洁的”常见的类似结构还有：blackandblue青一块紫一块；happyandgay高高兴兴heartandsoul全心全意，一心一意6．whatisawmademeverysad．我所见到的一切使我非常难过。

句中的主语whatisaw主语从句例如：

whatthelittleboydidsurprisedhismother.

小男孩所做的一切使他母亲十分惊讶。

whatyoudomakesmehappy.

你所做的使我愉快。

7.thelitterbasketswereemptyandgroundwascoveredwithpiecesofpaper，cigaretteends，oldtyres，emptybottlesandrustytins.

句中and连接的并列句，“thelitterbasketswereempty”与“groundwas...分别为两个并列分句，becoveredwith...被......覆盖。如：thedesksarecoveredwithdust.桌子上布满了灰尘。anyonewholeaveslitterinthesewoodswillbeprosecuted！

凡在此树林丢垃圾者，将依法处置。这是一个主从复合句，who引导定语从句，修饰先行词anyone。willbeprosecuted为将来时的被动语态。
