1. be+名词,译为:“......是......”

2.be+形容词,译为:“......怎么样”

注意:一定要分v-ing是现在分词还是动名词!
be+动名词是“系表结构”,
e.g. Our task is building a new TV tower.我们的任务是建造一座新的电视塔。
因为task是不能发出“正在建设”的行为,所以从逻辑上可以判定谓语不能构成进行时态。
4.be+状语,表示地点,位置。
He is from Japan.他来自日本。
The ticket is here.票在这儿。
The apples are on the table.苹果在桌子上。
5.be+不定式,表示计划、安排或约定要实行的行为。

注意:
1.“is/are to be +过去分词”这种结构含有can be,must be的意思。
e.g. These rules of the roads are to be strictly observed.=These rules of the roads must be strictly observed.这些交通规则必须严格遵守。
2.“is/are not to be +过去分词”含有“禁止”的意思。
e.g. The magazines are not to be taken out of the reading-room.杂志不准带出阅览室。
3.用逻辑判别法把上述用法和be后的不定式作标语的情况区分开
e.g. The main aim is to get good results.主要的目的在于取的好成绩。
"to get good results"作表语。
6.be+going+不定式,表示:“打算,计划,准备做......”
