  • 第1题:

    Many things __________impossible in the past are common today.

    A.to consider

    B.being considered

    C.considering

    D.considered


    正确答案:D
    considered impossible in the past是过去分词短语作定语,具有被动的意义。A.to consider是不定式的主动式,不对。B.是现在分词的被动式,表示“正在被考虑中的”,不对。C.是现在分词,表示主动,不对。

    下列Moore型状态机采用Verilog语言主控时序部分正确的是:

    A.always@(posedge clk or negedge reset) begin if(!reset) current_state<=s0; else current_state<=next_state; end

    B.always@(posedge clk ) begin if(!reset) current_state<=s0; else current_state<=next_state; end

    C.always@(posedge clk t) if(reset) current_state<=s0; else current_state<=next_state;

    D.always@(posedge clk or negedge reset) if(reset) current_state<=s0; else current_state<=next_state;
