dont feel I can trust him.不知怎么地，我觉得不能信任他。【即时应用】用anyhow/anyway/somehow填空(1)There is little chance that we will win the game._，we are still in very high spirits.(2)He could have finished the task on

以信号词语辨析：symbol/signal/sign/marksymbol指符号，象征，标志等。signal指信号，暗号或警告等。sign表示“记号、符号”时，同“symbol”；表示“告示、牌示”时，侧重指用图画、文字表达的告示、图示，此外还可以理解为“迹象、征兆”。mark普通用词，含义广泛。既可指为便于辨认而有意做的标记，又可指自然形成的标记或有别于其他事物的特征。【即时应用】
