10个句子,帮我检查下语法错误

1。正确2。正确3。We have to get assistance from (the) government,otherwise,we will fail。government前面要加the4。Steve has tried to fix the connector since two hours ago。最好这样改Steve has been trying to fix the connector since two hours ago (或者 for two hours)。5。Steve cannot enter the laboratory because he is not belonging here。后面有误,belong为动词,因此前面不能用助动词is,而要用does,修改如下：Steve cannot enter the laboratory because he does not belong here。6。Last night,my parents and I went to watch the performance in city centre,but both of us didn’t like it。后半句有错：but none of us liked it或者none of us enjoyed it7。The government announced a command that all of the citizen should not attack animal。8。When my girlfriend kissed I felt embarrass because my parents stood in front of me。kiss为及物动词,因此后面要有宾语,而embarrass也应该用ed形式,感觉如何,不能用原形,再有stood应该改成过去进行时态When my girlfriend kissed me,I felt embarrassed because my parents was standing in front of me。9。When we face dangers,our first reaction calls 911。danger没有必要用s,后面也有错误：When we face danger,our first reaction is to call 911。10。The commander gave a warning that all of the army should withdraw from the mountain last night。这里感觉时态有问题The commander gave a warning that all of the army should have withdrawn from the mountain by last night。
