13号刚期末考完,28号就要考T了。感觉时间很紧张。前一阵过了一遍OG的听力和阅读,现在开始主攻作文和口语。这两天在练DELTA上的integrated writing,感觉听的lecture的major points都能抓住,但是在具体写每一段的时候总觉得没话可说。是不是因为还是作笔记的能力不够,不能把其中的可以用来develop my writing的detail也记下来?那应该怎么提高呢? 另外附一篇今天写的integrated writing,是严格掐着时间写的,希望高手指点。//bow 题目是DELTA 409页 关于马尔萨斯人口论的。 The lecture states that Malthus's population theory is dead wrong, which is contrary to the proposition of Malthus about the relationship between population and economy discussed in the passage. The lecturer argues that though Malthus has carefully used statistics in his theory, still he left out some important factors.
The first flaw of Malthus's theory is that he did not take into account the advances in technology of food production. Today in North America and Europe, the food output is growing much faster with the aid of new techniques, which causes the real wage to increase so that the living standard is actually improving. This directly refutes the claim of Malthus that food production can only increase at an arithmetic rate.
Another factor Malthus didn't think of is the development in population control and education. With stricter control on birth giving and higher level of education, population is not growing as quickly as Malthus supposed. This also contradicts the point in the passage that if all the offspring survive, the population would double every generation.
Thus, the two assumptions of Malthus's theory, arithmetically growing food production and geometrically growing population, are both false. So the lecturer completely refutes the theory discussed in the passage. |
