They （excite) ______ about seeing their parents again.

inations on the World Wide Web, for about $6.7 billion in stock in one of the largest Internet company deals. The deal announced today would surpass America Online Inc. 's $4.2 billion acquisition of Netscape Communications Corp. last year. Based on closing stock prices Friday, Excite is worth about $ 3.4 billion, which would mean that At Home would be paying a huge premium. The deal could eventually give telecommunications giant AT&T Corp. control of one of the highly sought after portals that serve as entry points onto the Internet.

At Home is owned by Tele-Communications Inc. , Cox Communications and several other investors. TCI is in the process of merging with AT&T Corp. in a $39 billion deal that is expected to be completed by spring. AT&T Corp. chief executive Michael Armstrong has stated he wants to use At Home as a conduit tor delivering a wide range of communications services, including electronic commerce. Control over Excite, which has a search engine and links to several online shopping sites, would certainly enhance that goal. Excite, which has lagged behind other Web site companies, such as Yahoo!, has been looking for a larger partner in the rapidly consolidating Internet portal market, especially in wake of the AOL-Netscape deal. Several other companies had been rumored to be interested in Excite, including Yahoo! Inc. and Microsoft Corp. Negotiations between Yahoo! and Excite broke off this weekend, according to published reports.

Excite, eager to extend its reach and market power, was attracted by an alliance with AT&T and TCI. Excite's shareholders are expected to own about 30% of the combined company, which would be known as At Home Networks. Excite chief executive George Bell would take a position on the new company's executive board, reporting to At Home chief executive Tom Jermoluk. At Home, which delivers high-speed Internet service over cable TV lines, has more than 330,000 customers. The deal would give it access to Excite's more than 20 million registered users and to the company's content development capabilities. Both companies are located in Redwood City, Calif. At Home, whose stock has risen nearly 300% over the past year, has the money to make a deal, Michael Harris, president of Kinetic Strategies Inc. told MSNBC. "With At Home's existing stock valuation (of about $11.7 billion), it's been surprising they haven't done more deals. They've certainly got a huge war chest built up."

Neither company has yet made a profit. In the three months ended Sep. 30, Excite lost $6.8 million on revenue of $44 million, including acquisition and amortization expenses. In the same period, At Home lost $9.7 million.

Why does At Home want to buy Excite？

A．Because Tom Jermoluk wants to control his strongest competitor.

B．Because it wants to expand its business through Excite's present resources.

C．Because both companies are based in Redwood City, California.

D．Because it has lost $9.7 million in the last three months.

Australian researchers have discovered electroreceptors

(sensory organs designed to respond to electrical fields)

clustered at the tip of the spiny anteater’s snout. The

researchers made this discovery by exposing small areas of

(5) the snout to extremely weak electrical fields and recording

the transmission of resulting nervous activity to the brain.

While it is true that tactile receptors, another kind of

sensory organ on the anteater’s snout, can also respond to

electrical stimuli, such receptors do so only in response to

(10) electrical field strengths about 1,000 times greater than

those known to excite electroreceptors.

Having discovered the electroreceptors, researchers are

now investigating how anteaters utilize such a sophisticated

sensory system. In one behavioral experiment, researchers

(15) successfully trained an anteater to distinguish between

two troughs of water, one with a weak electrical field

and the other with none. Such evidence is consistent with

researchers’ hypothesis that anteaters use electroreceptors

to detect electrical signals given off by prey; however,

(20) researchers as yet have been unable to detect electrical

signals emanating from termite mounds, where the favorite

food of anteaters live. Still, researchers have observed

anteaters breaking into a nest of ants at an oblique angle

and quickly locating nesting chambers. This ability quickly

(25)to locate unseen prey suggests, according to the researchers,

that the anteaters were using their electroreceptors

to locate the nesting chambers.

According to the passage, which of the following is a characteristic that distinguishes electroreceptors from tactile receptors？

A．The manner in which electroreceptors respond to electrical stimuli

B．The tendency of electroreceptors to be found in clusters

C．The unusual locations in which electroreceptors are found in most species.

D．The amount of electrical stimulation required to excite electroreceptors

E．The amount of nervous activity transmitted to the brain by electroreceptors when they are excited
