Based on the working characteristic of Schmitt circuits which have two detection thresholds to input signals, this paper proposes that Schmitt circuits have the same sequential characteristic as flip flops which are used as memory units.

From the second experiment,similar facilitation effects of the gaze cue for both single feature and feature conjunction search was found,which revealed that gaze cue affected feature extraction as well as later processing stages (decision and response processes),but it did not influence feature integration directly.

Within the framework of the grammatical blending theory, this paper investigated the Clausal-Object Constructions, based on which their blending features are discussed and hopefully this will provide some insights into L2 grammar teaching.
