●Theweathermaybeveryhotanddryoritmaybeverycoldandwet.天气可能会非常炎热干燥,或者可能会非常寒冷潮湿。◎观察思考:1.Afterthesedrydays,everyonehopesforrain.干燥的天气之后,人人都希望下雨。2.Thebreadwilldryoutifitisleftonthetable.如果把面包放在桌子上,它会变干的。3.Dryhaircanbedamagedbywashingittoofrequently.干性头发洗得太频繁可能会受损。◎用法总结:1.dry可作形容词,意为“干燥的,雨少的”。2.dry作形容词,还可译为“干性的”。3.dry还可作动词,意为“使……干,擦干”。对点自测把下列句子翻译成英语1.我用毛巾擦干了双手和面部。______________________________________________________________2.我们应该为更干的天气做准备。______________________________________________________________【答案】1.Idrymyhandsandfacewiththetowel.2.Weshouldpreparefordrierweather.[命题点二]eventhough的用法
