試卷答案如下

一、單項(xiàng)選擇題

1.A

解析思路：Now()函數(shù)返回當(dāng)前日期和時(shí)間，Today()返回當(dāng)前日期，Date()返回系統(tǒng)日期，Time()返回系統(tǒng)時(shí)間。

2.A

解析思路：Caption屬性設(shè)置窗體的標(biāo)題欄文本，Title屬性不適用于窗體，Name屬性設(shè)置控件的名稱，Text屬性設(shè)置文本框的內(nèi)容。

3.B

解析思路：TextBox控件用于輸入和顯示文本，Label控件用于顯示文本信息，Button控件用于響應(yīng)用戶點(diǎn)擊，ListBox控件用于顯示列表。

4.B

解析思路：Click事件在用戶點(diǎn)擊按鈕時(shí)觸發(fā)，Load事件在窗體加載時(shí)觸發(fā)，DoubleClick事件在用戶雙擊控件時(shí)觸發(fā)，KeyPress事件在用戶按下鍵盤按鍵時(shí)觸發(fā)。

5.B

解析思路：Erase語句清除數(shù)組中的所有元素，Clear方法用于清除對(duì)象的內(nèi)容，Dim語句用于聲明變量，ReDim語句用于重新定義數(shù)組的大小。

6.A

解析思路：Const關(guān)鍵字用于定義常量，Dim關(guān)鍵字用
