11.12 綜合 TPO24 改
橘色建議 紅色錯誤
In the lecture, theprofessor is skeptical about the ideas of the idea of the reading passage that the 70-million-year-old fissile fossils of T.redx might still contain remains ofthe actual tissues of the animal. The professor argues that the materialsrevealed inside the T.rex’s leg bone might not be the remains of blood vessels, red blood cells,and collagen matrix.
In the reading passage, the presence of a soft, flexible organicsubstance inside the channels of fossilized leg bone may very well represent the remainsof the actual blood vessels of T.rex. On the contrary, the professor says thatthe soft, flexible organic substance is not necessary the remains of the actualblood vessel, but it may be somethingelse. For example, the bacteria will live in the hollow and empty the boneafter the animal die. What's more, the bacteria will leave behind the trace oforganic tissues. Hence, the soft substance may be left by bacteria. 前辈记得好多听力的details喔!!赞!!
The professor then opposes the reading's idea that the presence of sphere could be the remain of red blood cellsby stating that the sphere are also found in some other animals, include those without bloodcells (and some of these animal lives without read blood cells). 为了让文章看起来漂亮,建议每段篇幅尽量扯到差不多字数,可以用些转承词重述教授的论点,这样在时间内也能让篇幅变长. 这段少提到教授认为T-rexsphere可能只是reddishmineral.
Finally, the professor disapprove the reading's idea that collagen foundin the leg bone is exactly the kind of biochemical material that one wouldexpect to find in association with bone tissue. The professor points out thatthe collagen cannot last more than one hundred thousand years, ; however, the T-rex fossil is70-million-year-old, therefore the collagen may come from other resource,; for example, it may come fromthe human who touched it(the fossil) 第一段听力的detail足够,但二三段的细节稍嫌不足,再接再厉,会越写越好的! |
