问题 填空题

在窗体上加上一个文本控件PCSTextBox,画一个命令按钮,当单击命令按钮的时候将显示 “打开文件”对话框,设置该对话框只用于打开文本文件,然后在文本控件中显示打开的文件名。请填空。  Private Sub Command1_Click()    CommonDialog1.Filter=【 】     CommonDialog1.ShowOpen    PCSTextBox.Text=【 】   End Sub

答案

参考答案:"Text Files(*.txt)|*.txt"

解析:要设置通用对话框只用于打开文本文件,需要设置通用对话框的Filter属性值,在这里我们应该填写的是"Text Files(*.txt)| *.txt";在使用了对话框控件的 ShowOpen后出现的打开文件对话框中的文件类型只有Text Files(*.txt)|*.txt,选择了需要打开的文本文件后,应该让文件的文件名显示在文本框中,因此需要将通用对话框中选择的文件赋给文本控件,即将对话框的FileName属性值赋给文本框的Text属性。

完形填空

With the development of modern science and technology, the functions of cellphones have changed greatly.  小题1:  The only difference may be that they fit in your pocket and you pay by the minute to use them. Some of the things a cellphone can do for you will be available this year:

Surf at speed

Cellphones that let you use the Web have been around for years. So, what's new? Well ,  faster third-generation (3G)  networks that let you surf at anywhere. 小题2:Possible choices are from IJG Electronics VX 8000 and Motorola V1150.Listen as you go.

小题3:  There is no doubt that it is about to change. Sony Ericsson’s new W8001 can hold around 150 songs in its 500 MB memory. And Samsung's SPH-V5400 even comes with a l. 5 GB hard drive. Mobile phones may eventually replace miniMP3 players, especially for teens. Say cheese.

Camera cellphones are not new either but most of them have limitations: around l- megapixel  (百万像素 ) .  However new technology has made 2-megapixel units more common ,and 3-megapixel units are showing up soon. Some 2-megapixel models, like Sony Ericsson's K7501, offer limited zoom and focus controls.   小题4:Portable TV.

You say you like "watching TV"? That’s what Samsung MMA700 wants to give you. The new model lets users watch popular TV programmes~ for a fee. Other choices are Nokia's 6620, Sanyo's MM740 and NEC's N940.   小题5:The above are just a handful of what you ' ll see in the coming months.  Further down the road, your mobile phone may play a host of other roles, such as mobile credit card, position locator and so on. So what is there that a cellphone can't do?

A.The NEC model lets you watch public TV - no fee.

B.Without a cellphone, you can do nothing in your daily life.

C.Nowadays, new cellphones are much cheaper than old ones.

D.Today's do-it-all mobiles have a lot in common with the computer.E. This then allows a carrier to send video, music, and games to your phone.

F. Others, like LG's recent A7110, can even capture 30 minutes of full-motion video.

G. The problem with most cellphone MP3 players is that they hold only a handful of songs.

低碳生活处处可为

冯 云

       ①面对环境的恶化,科学家都鼓励人们过低碳生活。那么,什么是低碳生活呢?

       ②低碳生活涉及碳足迹,碳足迹表示一个人或者一个团体的碳耗费量,是测量某个国家和地区的人口因每日消耗能源而产生的二氧化碳排放对环境影响的一种指标。第一碳足迹是因使用化石能源而直接排放的二氧化碳,比如一个经常坐飞机出行的人会有较多的第一碳足迹,因为飞机飞行会消耗大量燃油,排放出大量二氧化碳。第二碳足迹是因使用各种产品而间接排放的二氧化碳,比如消费一瓶普通的瓶装水,会因它的生产和运输过程中产生的碳排放而带来第二碳足迹。碳足迹越大,说明你对全球变暖所要负的责任越大。碳足迹越小,说明你对环境的保护做出的贡献越大。

       ③就个人而言,每个人可以从自我做起,从生活中的细节做起,尽量减低碳足迹,选择低碳生活。例如,少开一天车,少吃一顿肉食大餐,少用一次性筷子,少开一盏灯等等,都可以减少碳足迹;甚至用餐做菜时选择烹饪方式也可以减少碳足迹。以土豆为例,用烤箱烘烤土豆产生的二氧化碳比用锅煮的要多,而用锅煮产生的二氧化碳又比微波炉做产生的多。所以,用微波炉做土豆就是一种更好的低碳生活。

       ④另外,棉布衣服与化纤衣服,爬楼梯与坐电梯,走路与开车等等,都是前者是低碳生活,后者是高碳生活。生产化纤衣服要消费更多的石油和能源,排放更多的二氧化碳,所以应当选择棉布衣服。在家居用电上,使用风电或水电等清洁能源产生的碳排放会比使用热电低。在交通出行方面,小排放量汽车在同距离时碳排放量较少,应大力推广小排量节能环保型汽车。

       ⑤尽管低碳生活值得提倡,但是,由于工作需要或其他原因,人们不时会进入高碳生活。这时就应当对自己的高碳生活进行补偿。这种补偿就是所谓的碳中和。这种补偿就是碳中和。碳中和指的是,人们可以计算自己日常活动(生产)直接或间接制造的二氧化碳排放量,如果过高,则可以通过植树等方式把这些排放量吸收掉,或者计算抵消这些二氧化碳所需的经济成本,然后个人付款给专门企业或机构,由他们通过植树或其他环保项目抵消大气中相应的二氧化碳量,以达到降低温室效应的目的。可以说,碳中和就是人们对自己高碳生活的补偿。

       ⑥因此,人类的低碳生活处处可为。(摘自《百科知识》,2009年第12期,有删改)

     答:                                                                                                                                              

2.“生产化纤衣服要消费更多的石油和能源,排放更多的二氧化碳”一句中为什么连用两个“更多的”?

     答:                                                                                                                                               

3.第③段画线部分运用了什么说明方法?有什么作用?     答:                                                                                                                                             

4.从全文看,文章主要内容是介绍“低碳生活”,但为什么还要谈“高碳生活”?

     答:
