17、句】There are thousands of birds in the forest.There are 2 thousand birds in the zoo. 原因状语从句1 because, since 和 as 的区别（1）because：语气最强，表示直接原因，可用于回答 why 提出的问题、引导表语从句、用于强调句等，而其余三者均不行：“Why didnt he come?” “Because he was ill.” “他为什么没来?”“因为他病了。” We must stay at home because it rained. 我们必须呆在家，因为下雨了。（2）since
