8、e too. I cant wait to see everyone. It should be lots of fun.答案与解析语篇解读这是感恩节当天，中国留学生Steve和美国学生Alice的英语口语对话。美国的圣诞节和感恩节就像中国的春节一样，全家会吃团圆饭。Alice详细地对Steve介绍了在美国常见的感恩节食物。1friends被all修饰， friend是可数名词，需用复数形式。2going to do对话中说的是要过感恩节，因此是感恩节的时候会做什么，因此用be going to表将来。误解分析：此处如果没有结合语境及语法常识，就容易出错。3If此处是表条件含义，因此用if引导
9、条件状语从句。4to comewould like/love后需接动词不定式。5wonderful此处表达“好极了”，因此用wonderful作表语。6how依据语境可知，此处表示去看看其他家庭如何过感恩节，因此用how。7a此处表“一次大型的家庭聚会”之意，因此用a。8like/such as前面提及lots of delicious food，此处举例，因此用like或such as。9sounds本段对话是现在的事情，且主语是第三人称单数形式，用sounds。10it此处表示“想到感恩节大餐就饿了”，因此用it代指。语 篇 提 能.阅读理解In early October, thousa
