题目:

(6分)如图所示,一根张紧的水平弹性绳上的a、b两点相距14.0 m,b点在a点的右方,当一列简谐波沿此绳向右传播时,若a点位移达到正向极大,b点的位移恰为零且向下运动,经过1.00 s后,a点的位移为零且向下运动,而b点的位移恰好达到负向极大,则这列简谐波的波速可能等于________。

A.14.0 m/s

B.10.0 m/s

C.6.00 m/s

D.4.67 m/s

任务型读写。

     阅读下面短文,根据所读内容在表格中的空白处填入恰当的单词。

     注意:每个空格只填一个单词。

                                                      Robot (机器人) revolution

     The day that a robot wakes you up, cleans your room and walks your dog might still be a few decades

off. But increasingly, engineers are saying that robots are going to make the leap (跳跃) from the factory

floor to your family room.

     Companies like Sony and General Electric are working on designs for small robots. Products like the

Roomba, a robot that can clean floors, are flying off the shelves. On the cover of a recent issue of Scientific

American magazine, Bill Gates predicted the "Dawn of the Age of Robots".

     What's behind this new era (时代)? It's partly a matter of technology. Devices that can recognize and

respond (回应) to a human voice have been developed. There are now a few different ways for robots to

move around. They can walk, crawl (爬行) or ride on wheels. They are being made smaller and smaller.

They are also becoming more and more energy efficient.

     A bigger part of the story is on the demand side. From the day Robert Adler invented the television remote

control in the 1950s, people around the world have tirelessly searched for ways to get lazier.

     Also take into consideration the increasing wealth of rich people, the time appears ripe to introduce robots

to ease our daily lives.

     To be sure, robots that walk on two legs and talk like people are still too complex for our present

engineering abilities. Today's robot revolution is to make them for everyday use. Robots will do basic

housework such as cleaning or gardening, or just help you have more fun on the basketball court.

     What makes a robot different from an ordinary cleaning machine is not the presence of computer chips

(芯片). Nowadays even your microwave has a computer chip. It is the ability to sense and make changes

to the environment (环境) in real time.

     For example, a floor-cleaning robot should be able to sense your scared cat and move out of the way.

Today's computing ability is, for the first time, able to make machines that could "think", at least in certain

limited ways.

案情:神码电子公司欠连发生物技术公司120万元债款,连发生物技术公司欠广宁公司150万元债款。这两笔债款均已到期。广宁公司向连发生物技术公司讨要欠款时,连发生物技术公司还款30万元给广宁公司,并向广宁公司表示无力偿还余下的120万元,但同时连发生物技术公司一直不向神码电子公司主张自己的到期债权120万元。于是,2004年10月7日,广宁公司以自己的名义以神码电子公司为被告向法院提起诉讼,要求把神码电子公司欠连发生物技术公司的债款120万元拨到广宁公司的账上。在诉讼过程中,神码电子公司的另外两家债权人甲、乙两公司得知情况后,于2004年11月9日,也起诉到法院,要求与广宁公司均摊120万元的债款。广宁公司在诉讼过程中,申辩说自己具有优先权,因为这120万元的债款已经打到自己的账上。
问题:

广宁公司以自己的名义以神码电子公司为被告所提起的诉讼中,连发生物技术公司的诉讼地位如何法院可否把连发生物技术公司追加为当事人
