s.这要严重得多。本句much意为“......得多”，修饰形容词的比较级。如：muchmorebeautiful漂亮得多muchstronger强壮得多Heismuchbettertoday.他今天好多了。Thefoo

dhas__________.（已经变质）2.Myfoodhasgonemissing.我的食物不见了。go在这里做连系动词,意为“变成,处于…状态”(go表变化时一般指事情向消极、不好的方面转化)。如：gonebad拓展gone表示“丢了,

没了”,含一去不复返的意思,也可以表示“死了”,作表语或宾补,不可以作定语。Myfeverisgone,butIstillhaveacough.发烧消退了,但我仍然咳嗽。lost表示“丢失”,含难以找回的意思,可作定语、表语或宾补。Thepare

ntsfoundthelostchildatlast.家长终于找到了迷路的孩子。missing意为“缺少的，丢失的”Thereisapagemissingfromthisbook.此外，missing还有“失踪的，行踪不明的”之意。Theyarelookingforthemis

_forever.Lostmissinglost3.IguessJimmyWhiteislying.lying为lie的现在分词,这里表示“说谎”Itwasverydishonestofyoutolieto

themaboutyourscores你向他们谎报分数是很不诚实的。Itisnotrighttolieaboutyourhealthtogetcheapinsurance.虚报你的健康状况以获取廉价的保险是不对的。lie还可作名词tellalie说谎拓展lie作动词，还有“平躺

；位于”的意思。Helaydownonthesofaandsoonfellasleep.他在沙发上躺下很快地睡着了。TaiwanliesinthesouthofChina.台湾位于中国南部。词义原形过去式过去分词现在分词说谎lieliedliedl

ying躺；位于lielaylainlying放置；下（蛋）laylaidlaidlayinglie的第一个意思是说谎，它的过去式和过去分词是规则变化的，加d，lied、lied。如：Healwaysliedtohisfatherlastsummerholid

ay.去年暑假他总是向爸爸撒谎。我们在向父母撒谎的时候总是尽量避免被揭穿，我们的目的都是一样—骗人！从这个方面说我们撒谎是规则的。我们可以用口诀法来记忆，第一句是：规则的去说谎。巧记lie和laylie第二个意

思是“位于”，第三个意思是“躺”。我们可以想象，晚上睡觉时躺的姿势是格式各样的，更有甚者180度大变换，所以躺是不规则的。也就是说“位于、躺”这两个意思过去式和过去分词是不规则变化的：lie、lay、lain。可以用这一句口诀记忆：不规则位于、躺。lay不仅是lie的

过去式，它又是下蛋、放的原型。我们再用一句口诀来记忆：躺过去下蛋。这句的意思是躺的过去式下蛋的原型。例如：Thehenlaysanegginthebasket.母鸡在篮子里下了蛋。lay做原型时是“下蛋；放”的意思，而且它的过去式和过去分词也是

不规则变化，最后一句口诀随之出现：下蛋放一起，就是说他们的过去式和过去分词一起变化，一样的：lay、laid、laid。例如：ThehenlaidaneggyesterdayandIlaiditintothebasket昨天鸡下了一个蛋，我把它放到篮子里。四句口诀：规则的去

说谎，不规则位于、躺，躺过去下蛋，下蛋放一起。Justafterputtingthebabyontobed,Mrs.Whitesuddenlycaughtsightofthepetcatanddidn'tknowhowlongit_____

：表示“躺、在、位于”的不及物动词lie---lay---lain---lying;表示“放置、下(蛋)”的及物动词lay---laid---laid---laying。第一空是“躺”的过去完成进行时;第二空是“摆放
