2、time?_2.Write down the main idea for each paragraph.Paragrapg1_Paragrapg2_Paragrapg3_Paragrapg4_3.句式点击：At first my new surroundings were difficult to tolerate.开始的时候，新的环境让人难以忍受。本句型为“主语+be +adj.+ to do”不定式用于形容词后作状语，其逻辑宾语为句子主语，但不定式要用主动形式表示被动含义。若其中的动词为不及物动词，则应在其后加相应的介词。如：These programs are usually easy
3、to receive.这些节目通常容易接收到。The box is heavy to carry.这个箱子搬起来很重。注意：该句型的主语可以是人，也可以是物。用于此句型的形容词有 easy, hard, comfortable, difficult, heavy 等。However , I lost sight of Wang Ping when we reached what looked like a large market because of too many carriages flying by in all directions.然而，当我们到达一个看上去是大市场的地方时，由于

Out rushed the children. 孩子们冲出去了。In front of the house stands a tall tree. 在房子的前面有一棵大树。三语法分析：过去分词作定语和状语1. 过去分词作定语 过去分词作定语时，和所修饰的中心名词之间存在被动关系，可以转化成一个定语从句。eg. I like the boo
