Task Overview
Reading Passage
Underwater, whales produce loud noises, known as songs. Scientists use whale songs to study the movements, or migrations, of groups of whales. Recently, scientists discovered something unusual: a single, solitary whale whose song is unlike that of all other known whales. The most notable difference between this unusual whale’s song and those of other whales is its high pitch or frequency. This unique whale is called the 52-hertz whale because it sings at the unusual frequency of 52 hertz, a much higher pitch than normal. When the 52-hertz whale was first detected, the cause of its uniquely high-pitched song was unknown; however, scientists now have several theories to explain it. One theory holds that the 52-hertz whale may be a hybrid: the offspring of two different whale species. Whales of different species are known to interbreed and produce hybrid offspring that combine characteristics from each of their parents’ species. As a hybrid, the whale may have a unique song, different from that of either of its parents because it resulted from a combination of the two. A second theory is that the 52-hertz whale may have a damaged sense of hearing. Just as people learn to speak by copying the sounds they hear, whales may learn to sing by listening to the sounds of other whales’ songs. When people are born deaf, their speech may sound different from that of people born hearing. Similarly, the 52-hertz whale’s songs may sound different simply because it cannot hear the songs of other whales. A third theory holds that the 52-hertz whale may be the only known member of a rare species. Perhaps there were once many more whales of this species, but most are now gone. It seems to be entirely unique only because most of its species has died out.

The passage gives three plausible explanations for the uniqueness of the high-frequency sound. In contrast, the professor rebuts each explanation and concludes the cause of the strange sound still remains mysterious. First and foremost, the reading suggests the peculiar species may be a hybrid, which was combined with two different species. However, the professor points out a common scenario that a hybrid whale will follow, they will chase those non-hybrid species. What the researchers have observed is the contrary, the 52HZ whales didn't follow certain type of species, instead they developed their own unusual pattern. This evidence highly contradicts the theory that claims that the 52HZ whale is a hybrid species. Secondly, the passage emphasizes the common reason why certain humans can't produce a normal-they have a damaged sense of hearing. So this can be a reasonable analogy to explain why certain whales produce 52HZ sounds. The professor highlights the fact that the unique sounds have a high pitch, which only can be produced with a physical structure in the throat, and this structure has no connection with the hearing system. Therefore, this theory failed to elaborate an entire event. Thirdly, the passage infers the 52HZ species may be the only known species in which many of the same species have died, distincting the unique species, but the professor contends this assumption by questioning why researchers didn't detect this species' parents. They had used technology to find peculiar sounds in recent years, but they never heard before this one.

示例1: 原文:"What the researchers have observed is the contrary, the 52HZ whales didn't follow certain type of species, instead they developed their own unusual pattern." 修改后:"What the researchers have observed is contrary to this theory, as the 52-hertz whale does not follow any specific species but instead has its own unique migration pattern."
示例2: 原文:"The professor highlights the fact that the unique sounds have a high pitch, which only can be produced with a physical structure in the throat, and this structure has no connection with the hearing system." 修改后:"The professor emphasizes that producing such high-pitched sounds requires a unique physical structure in the whale's throat, which is unrelated to its hearing system."

Section Title: 6.文章修订
The passage presents three possible explanations for the unique high-frequency song of the 52-hertz whale, while the lecture refutes each theory and asserts that the cause of this unusual sound remains a mystery.
Firstly, the reading posits that the 52-hertz whale may be a hybrid, resulting from the combination of two different species. However, the professor counters this by stating that hybrid whales typically follow non-hybrid species during migration. Contrary to this pattern, researchers have observed that the 52-hertz whale does not follow any specific species but instead has its own unique migration pattern. This evidence significantly undermines the theory that claims the 52-hertz whale is a hybrid species.
Secondly, the passage draws an analogy between humans with damaged hearing who cannot produce normal speech and whales producing high-frequency sounds due to impaired hearing. The professor refutes this theory by emphasizing that the unique high-pitched sound can only be produced with a specific physical structure in the throat, which has no connection to their hearing system. Consequently, this explanation fails to provide a comprehensive account of why these whales produce such unusual sounds.
Lastly, the passage suggests that perhaps the 52-hertz whale is part of a rare species where most members have died out, leaving only this unique individual. The professor disputes this assumption by questioning why researchers have not detected any other members of this supposed rare species, such as its parents. Despite using technology to search for unusual underwater sounds in recent years, scientists have never encountered any similar songs before discovering this particular whale's song. (261 words)
