4、If teens see that their physical condition is causing them to perform badly, they may _(motivate) to do other activities to get healthy.【答案】1.considered/should consider。在“It is high time that”句式中，从句用虚拟语气，即：谓语动词用过去式或“should+动词原形”。2.had happened。由was 可知，此处表示对过去的虚拟，故从句用过去完成时。3.(should)be sent。表示建议、要求、命
5、令等的名词后的宾语从句、同位语从句中谓语动词用“(should+)动词原形”。4.wouldnt be。句意：如果我没有面对过那么多的障碍，我就不会是今天的我。根据语境可知，该句为错综虚拟条件句，从句是对过去的虚拟，主句是对现在的虚拟。故填wouldnt be。5.had been put。句意：如果新的安全系统被投入使用，这起事故就不会发生了。根据题干中的主句谓语部分“would never have happened”可知，语境是对过去发生的事进行虚拟，因此if引导的从句谓语部分应为had done。再结合语境，可知用被动语态。6.came。“would rather”后面接从句时，从句中
6、的谓语动词通常要用一般过去时，表示对现在或将来的假设。7.must。句意：既然没人给他帮忙，那他肯定是自己做的研究。主句是对从句表达的原因的一种猜测，must have done意为“想必/准是/一定做过某事”,符合主从句之间的逻辑关系。8.be chosen。主语he和动词choose之间是被动关系，空格前有would,故用“be+及物动词的过去分词”。9.had been。句意：我真希望上周二参加了妹妹的婚礼，不过我当时正在纽约出差。根据句中的but可知，“我参加了妹妹的婚礼”只是一种假设，根据空格后的时间状语“last Tuesday”可知，动作发生在过去，此处表示与过去事实相反的假设，
7、故谓语用“had+过去分词”结构。10.be motivated。分析句子结构可知，本句中的主语they与动词motivate之间构成被动关系，且情态动词may后需要跟动词原形，故填be motivated。.语法填空Tom and Peter are twins.They look as if they 1.
