述语序，先排除B、C两项；主句中谓语动词用的是一般过去时，宾语从句的时态要与主句时态相呼应。含宾语从句的复合句，主、从句的时态呼应包括以下三点内容:(1)如果主句是一般现在时，从句可根据需要,选用相应的任何时态。考点3宾语从句的时态Idon’tknowwhenhewillcomeback.我不知道他将何时回来。Hetellsmethathissistercamebackyesterday.他告诉我他姐姐昨天回来了。(2)如果主句是过去时，宾语从句只可根据需要选用过去时,即一般过去时、过去进行时、过去将来时或过去完成时中的某一种形式。Thechildrendidn’tknowwhohewas.孩子们不知道他是谁。Heaskedhisfatherhowithadhappened.他问他父亲那件事是如何发生的。(3)如果宾语从句所表示的是客观事实、普遍真理等,不管主句用什么时态，从句都用一般现在时。

Theteachersaidthattheearthgoesaroundthesun.老师说过地球绕着太阳转。中考在线3：Johntoldhislittledaughtertheearth________fromthewesttotheeast.A.movedB.movingC.movesD.moveC【点拨】本题用语法判定法。考查宾语从句。句意：约翰告诉他的小女儿地球从西向东转动。该句为含有宾语从句的复合句，其中从句内容为客观真理，不管主句为什么时态，从句都为一般现在时。速记小法：宾语从句用法歌诀：宾语从句三注意,时态、语序、引导词。主句若是过去时,主、从时态要一致；宾从表达是真理,一般现在代过去。引导词也不难,陈述要用that连。语法讲解一般问句表“是否”,if或whether来引导。特殊问句作宾从,疑问词引导就可以。还有一点要说明,陈述语序要记清。用Whynot...,Whydon’tyou...,What/Howabout...,Let’s...和Shallwe...来提出建议。考点Whynot与Whydon’tyou后面接动词原形，What/Howabout后接名词、代词或动词的-ing形式，Le
