閱讀: 菊石( Ammonites ,軟體動(dòng)物門(mén)頭足綱的一個(gè)亞綱)是因?yàn)樾⌒行亲矒艉蟮囊幌盗?影響而滅絕的。
1. 酸雨。小行星撞擊后的酸雨,使漂浮在海平面上的菊石幼體死亡,所以導(dǎo)致了其滅絕。
2. 浮游生物( zooplankton )的死亡。小行星撞擊使大量浮游生物死亡,而浮游生物是菊 石的主要食物來(lái)源,菊石因食物匱乏而滅絕。
3. 氧氣缺乏。小行星撞擊造成氧氣缺乏,所以菊石無(wú)法生存。
聽(tīng)力:這三個(gè)理論都是不可信的。
1. 酸雨雖然會(huì)對(duì)菊石造成影響,但當(dāng)時(shí)還有另一種生活在海里的frog ,這種frog 至今還 在地球上存在,如果酸雨對(duì)菊石造成影響的話,這種frog 也應(yīng)該會(huì)滅絕,但是并沒(méi)有。
2. 浮游生物( zooplankton )只是菊石食物的一小部分,在所有菊石種類(lèi)中,只有個(gè)別種 類(lèi)以浮游生物為食,所以浮游生物的滅絕不會(huì)對(duì)大部分的菊石造成影響,所以該理論不成 立。
3. 菊石有特殊的身體組織,可以讓它在低氧的環(huán)境下也能夠呼吸生存,所以氧氣缺乏也 不是導(dǎo)致菊石滅絕的可靠原因。
The reading and listening both talk about whether the Ammonites died out due to asteroid apocalypse. However, the lecturer lists three reason to contradict what the passage indicates.
First, according to the lecturer, if the acid rains had killed off the ammonites on the surface of the water, another kind of frog, which also lived near the ocean, would become extinct as well. However, they still exist till now. Thus, the acid rain caused by asteroid impact mentioned in the reading passage was not the main reason.
Secondly, the reading passage indicates that the disappearance of zooplankton, which was the main food of ammonites, directly cause the extinction of them. However, zooplankton was just a small part of their food supply, according to professor, only a part of ammonites lived on zooplankton. Therefore, zooplankton didn't account for that.
As to the third reason of absence of oxygen, the professor claims that the special physical structure allowed ammonites to live with hypoxia, which means that the statement in the reading that the impact taking away oxygen from the atmosphere killed all of ammonites is not correct.

Do you agree that it is better to work for business owned by someone else than to work for the business of one,s own family It is better to work for business owned by someone else than to work for the business of one's own family.
Fresh graduates are facing the challenge of job-seeking and a large amount of them try to take the short cut that their family can offer some job opportunities for them, whether they suit these position or not. However, they are too shortsighted to realize the opposite consequence. Given the choice, I wouldn't take this kind of job which is under the influence of my family.
Firstly, they can't be sure whether what their family do is their own favorite. If not, the rest of their career lives will very likely be a suffering. My cousin, who was worried about finding job after graduation and eventually employed by the company owned by his uncle, suffers from the depression due to boring and hopeless working day. I don't th ink there is anyone who would sit idly by while their offsprings are all but dead in workplace. Thus, for the true meaning of work, don't compromise and choose the job just to avoid being a temporary “ loafer ”.
Even if the job fit their interest like a glo ve, it's hard for them to make achievements due to the limitation from stereotype of their family. People always expect more from those who have built- in advantages but when those people don't perform well enough, the great disappointment appear. Similarly, when all others think you should be the first because of the so-called relations of family bond, you are not allowed to make any mistake, otherwise you will be regarded as a failure. Since there are double difficulties to be successful than working in other companies, they are not supposed to be the prisoners in a small jail with no top.
As a rule, everyone dreams to work in a company whose boss is your father, and because of this, he or she can get rid of the office rules and behave freely. However, a company with unfair leaders will stop to go because of the unfair management and suspicious working relations. Would anyone like to stay in a sinking ship without expectation and hope? Accordingly, whether their father provide them with “ convenience or not , I don't think it is the job that they truly want.
In conclusion, in view of the own interest, unlimited working place and bright career lives, young people should be vigilant when they are thinking of the company where the family members work.
