"【C4】______, play is under-valued and lot of that is because of top-down【C5】______over standards and testing." "Their work is often framed in trying to【C6】______out whats wrong with these kids. Its very【C7】______and not at all what I【C8】______as a classroom teacher. " "I found the children【C9】______to learn, and their families were supportive and curious," she adds. "So when I got to academia, I thought it was【C10】______to read all these studies about kids not being【C11】______, or not being able to solve problems." So she【C12】______her own research project with a different approach. She is【C13】______the same minority group of 14 young children for three years, starting in【C14】______, to see how they learn mathematics, both in the【C15】______classroom setting as well as informally in school, and at home. "Just sitting there, looking at what is happening in their【C16】______surroundings, you can find things that【C17】______you," she says. She hopes her research will prove how important play is to【C18】______problem-solving skills, and in other critical ways. 【C19】______there is something else, just as important for Parks. "It is the equity piece of trying to change the conversation in the research community about what kids can do generally, and what minority kids can do【C20】______," she says.

Last but not least is the delicate meat to be found in the smaller limbs just behind the claws. This part of the lobster offers a relatively large amount of easily obtainable meat with relatively little effort. How to eat a lobster, then, is fairly simple.

A、The technique for eating a steamed lobster is relatively simple.

B、This part of the lobster offers a relatively large amount of easily obtainable meat with relatively little effort.

C、How to eat a lobster, then, is fairly simple.

【单选题】作为一名TestKing的软件开发人员，你正在创建一个在可更新DataGrid控件中给用户提供数据的ASP.NET应用程序。用户在网格中更新数据。你的代码使用System.Data命名空间和System.Data.OleDb命名空间。数据改变保存在ADO.NET DataTable对象中。你想当用户完成修改时用户的修改数据保存在数据库中，写了以下程序来完成任务： Public Shared Sub UpdateTestKData(_ ByVal sql As String,_ ByVal connectionString As String,_ ByVal dataTable As DataTable) Dim da As New OleDb.OleDbDataAdapter() Dim cnn As New OleDb.OleDbConnection(_ connectionString) dataTable.AcceptChanges() da.UpdateCommand.CommandText = sql da.UpdateCommand.Connection = cnn da.Update(dataTable) da.Dispose() End Sub 当用户编辑数据时，代码运行完成，但没有数据改变出现在数据库中。你测试代码中的更新查询和连接字符串，但都正常运行。你需要修改代码来确保数据更改在数据库中出现，该怎么做？

A、在调用Update方法之前添加以下两行代码： Dim cb As New OleDb. OleDbCommandBuilder(da) cd.GetUpdateCommand( )

B、在调用Update方法之前添加以下代码： da.GetUpdateCommand.Connection.Open( )

C、删除这行代码： dataTable.AcceptChanges( )

D、删除这行代码： da.Dispose( )

【单选题】你的应用程序将允许用户从一个名为Widgets的表中删除记录. 这个表含有一个名为ComponentsID的主键，Widgets表中的每一行都跟ComponentsTable表中的若干行相关联，ComponentsTable表也包含一个名为ComponentsID的列.当你从Widgets表中删除一行后，你希望ComponentsTable表中与此相关联的行也自动的被删除掉. 你已经写了如下的一些代码（行号只是作为参照作用）： 01 Dim columnOne As DataColumn 02 Dim columnTwo As DataColumn 03 Dim myRelation As DataRelation 04 columnOne = MyDataSet.Tables("Widgets").Columns("ComponentsID") 05 columnTwo = MyDataSet.Tables("WidgetDetails").Columns("ComponentsID") 06 07 MyDataSet.Relations.Add(myRelation) 下列的哪一行代码该放在第6行？（选择一个最佳答案）

A、myRelation = New DataRelation(MyDataSet.Tables("Widgets"), columnOne, columnTwo)

B、myRelation = New DataRelation("WidgetsWithComponents", columnOne, columnTwo)

C、myRelation = New ForeignKeyConstraint(MyDataSet.Tables("Widgets"), columnOne, columnTwo)
