问题描述：
the boy has performed excellently -----he was a bit nervous
a,except that b,in that c,except for
答
是这样的。
except that后面+句子；
except for+名词或动名词；
in that也是+句子，意思是“是因为...”
因为he was a bit nervous是一句明显的主谓宾句子，所以排除C，B句意不对。
所以选A
翻译：这个男孩的表现很优秀，除了有一点点紧张。
答
a,except that
答
那个男孩儿表现的很优秀,除了有点儿紧张.except for 后面只能跟介词不能跟句子,in that 是因为的意思,不符合句意.选A .
