一般现在时:I make love with her everyday.
一般过去时:I made love with her yesterday.
一般将来时:I will make love with her tomorrow.
现在进行时:I am making love with her.
过去进行时:I was making love with her at this time yesterday.
将来进行时:I will be making love with her at this time tomorrow.
现在完成时:I have made love with her by now.
过去完成时:I had made love with her before yesterday.
将来完成时:I will have made love with her by tomorrow.
现在完成进行时:I have been making lovewith her for two hours.
过去完成进行时:I had been making love with her for two hours when her husband came in.
将来完成进行时:I will have been making love with her for two hours when her husband wakes up tomorrow morning.
還可以學介詞。。make love with her, make love to her, make love in our room, make love on the couch, make love under the table, make love from behind...等等等等
少了过去将来的一组时态，不过这其实不能算作一种时态吧， If possible, I would make love with her at any time. If you were her, I would be making love with you right now.
I wouldn't have made love with her if you had not introduced me to that place.
Had the police not broken in, I would have been making love with her, uninterrupted, the whole afternoon.
一英语基本句型-1主系表结构/S (主）+ V（谓）（lv)( 系动词）+ P（表） The cake tastes delicious.
二英语基本句型-2主谓结构/S(主）+ Vi（不及物动词）（谓）
本结构是由主语加不及物的谓语动词构成, 常用来表示主语的动作。 如：The sun rises. Tom has already left. 主语可有修饰语-定语，谓语可有修饰语-状语。 如：1. The red sun rises in the east.
三英语基本句型-3主谓宾结构/S (主）+ Vt （及物动词）（谓）+ O（宾） 本结构是由主语+及物的谓语动词+宾语构成。宾语成分的多样化使得这一结构异常复杂。
如：1. Tom made a hole in the wall.
四英语基本句型4 双宾语结构/S (主)+VT（谓）+ InO（间接宾）+ DO（直接宾） 说明：此结构由“主语+及物谓语动词+间接宾语（人）+直接宾语（事物）”组成。 如：He brings me cookies every day.
但若要先说出直接宾语（事物），后说间接宾语（人），则要借助于介词to或for。
如：He brings cookies to me every day.
五英语基本句型5 复合宾语结构/S (主）+ VT（谓）+ O（宾）+ O C（宾补） 说明: 此结构由“主语+及物的谓语动词+宾语+宾语补足语”构成。宾语与宾语补足语之间有逻辑上的主谓关系或主表关系，若无宾语补足语，则句意不够完整。可以用做宾补的有：名词，形容词，副词，介词短语，动词不定式，分词等。 如：The sun keeps us warm.
六英语基本句型6 There be 句型
说明： 此句型是由“there+be+主语+状语”构成，用以表达存在关系可以称“……有……”。 它其实是倒装的一种情况，主语位于谓语动词 be 之后，there 仅为引导词，并无实际语意。
此句型有时不用be动词，而用 live, stand, come, go, lie, remain, exist, arrive等。
如：There stands a hill in the middle of the park.
