However[usage-however]

However。当意思是"nevertheless"（然而）时，避免用它来开头一句。这个词在不出现在句首时通常更合适。

• 误：The roads were almost impassable. However, we at last succeeded in reaching camp.
• 正：The roads were almost impassable. At last, however, we succeeded in reaching camp.

当however位于句首时，意为"in whatever way"（无论以何种方式）或"to whatever extent"（无论到什么程度）。

However you advise him, he will probably do as he thinks best. However discouraging the prospect, they never lost heart.
