|
| to spend and waste extravagantly |
|
| downhearted
lax and low-spirited
unable to restore |
|
| cannot find any ways to slove the problem |
|
| at the critical moment of crisis |
|
| to be bright and comprehensive |
|
| |
|
| to understand thoroughly |
|
| subtle and tiny |
|
| to seek to survive afte hazards |
|
| all alonea lonely guy |
