【分析】
本题考查被动语态的用法，解题思路为：先判断句子主语与括号内动词的主被动关系（主语是动作承受者则用被动语态），再结合句中时间状语、语境确定被动语态的具体时态，最后写出对应结构的正确形式。
【解析】
1. 主语the long bridge是build的承受者，时间状语in two months表将来，用一般将来时被动语态，结构为will be +过去分词，故填will be built。
2. 主语where to have the meeting是discuss的承受者，时间状语now表现在进行，用现在进行时被动语态，结构为is being +过去分词，故填is being discussed。
3. 主语which language是speak的承受者，表客观事实用一般现在时被动语态，结构为is +过去分词，故填is; spoken。
4. 主语the lost boy是find的承受者，时间状语so far表现在完成，否定形式用hasn't been +过去分词，故填hasn't been found。
5. 主语a large number of trees是cut的承受者，时间状语last year表过去，复数主语用一般过去时被动语态，结构为were +过去分词，故填were cut。
6. 主语the students是tell的承受者，频率副词often表一般现在时，复数主语用被动结构are +过去分词，故填are; told。
7. 主语he是send的承受者，情态动词must的被动结构为must be +过去分词，故填must be sent。
8. 主语Vegetables, eggs and fruits是sell的承受者，表客观情况用一般现在时被动语态，复数主语用are +过去分词，故填are sold。
9. 主语knives和答语中的they都是make的承受者，表客观事实用一般现在时被动语态，复数主语用are +过去分词，故填are; made; are made。
10. 主语the magazine是take的承受者，情态动词can的被动结构为be +过去分词，故填be taken。
【答案】
1. will be built 2. is being discussed 3. is; spoken 4. hasn't been found 5. were cut 6. are; told 7. must be sent 8. are sold 9. are; made; are made 10. be taken
