It took about two weeks to arrive, and it was a bit damaged, but it was so nice to get some sweets and jam from home; I’ve been dying to have some of my favouriste sweets, and it’s always nice to get mail! Para.1 3月8日 我刚收到一个从家里寄来的包裹！大约花了两周的时间包裹才到达，而且有点破损，但是真高兴能收到家里寄来的糖果和果酱我一直非常渴望吃一些我最喜欢的糖果，而且收到邮包总是令人开心不已。 1. get a parcel from sp从某地收到一个包裹 2.

It took about two weeks to arrive, and it was a bit damaged, but it was so nice to get some sweets and jam from home; I've been dying to have some of my favourite sweets，and it's always nice to get mail！ 【分析】 (1)句中but连接表示转折关系的并列句，其中最后一个and连接表示顺承关系的并列句. (2) It took about two weeks to arrive it was so nice to get some sweets... it's always nice to get mail it为形式主语，真正的主语为后面的动词不定式短语。 it takes/ took sb.+时间 +to do sth 花费...做某事 it be + adj. + to do sth.，做某事是...的， Para.1 长难句分析和仿写 I've been dying to have some of my favourite sweets，and it's always nice to get mail！ 【分析】(3) be dying to do 极想做，渴望做 同义词： long/desire to do... = be eager/anxious to do... 渴望做…… be dying/thirsty/eager/anxious for... = long for... = have a desire for... 渴望得到…… We’re dying to visit Hainan Island，located in the south of China. 我们非常想去位于中国南部的海南岛。 Para.2 到现在我已经在丛林里待了大约一个月了。我所在的中学是一所丛林学校。教室是用竹子搭建的，黏土夯的地面，茅草搭的屋顶。沿着杂草丛生、尘土飞扬的小路，我几分钟就能走到学校。 6.secondary school中学 7.be made of用……造成 8.down a dusty track沿着尘土飞扬的小路 9.be covered in sth.盖满了... So I’ve been here in the jungle for about a month now.
