GRE argument

题目：A recent study of eighteen rhesus monkeys provides clues as to the effects of birth order on an individual's levels of stimulation The study showed that in stimulating situations (such as an encounter with an unfamiliar monkey), firstborn infant monkeys produce up to twice as much of the hormone cortisol, which primes the body for increased activity levels, as do their younger siblings. Firstborn humans also produce relatively high levels of cortisol in stimulating situations (such as the return of a parent after an absence). Write a response in which you discuss one or more alternative explanations that could rival the proposed explanation and explain how your explanation(s) can plausibly account for the facts presented in the argument.

  According to the letter, the study demonstrated the relationship between rhesus monkeys' birth order and individuals' stimulation levels.But there're still alternative explanations accounting for the illustrated phenomenon against that argument.

    At the beginning, such assumption should be established on a large size of representative sample in statistics. Due to the experiment in this argument, the sample size of those eighteen chosen rhesus monkeys is too small to represent their entire species. I


    Secondly, the original explanation isn't persuasive to verify comparing two species under the same circumstances. The argument mistook human infants' explanation for the reference to rhesus monkeys' similar situation without a controlled experiment, whose result is supposed to be based on keeping all the other variables fixed except for the crucial hormone cortisol level condition.Moreover, the argument didn't explain the physical mechanism related to firstborn humans and firstborn infant monkeys. If there are any differences between those two species, the original explanation will be incorrect. The author should dwell on the cohesion between the human race and rhesus monkeys.

Last but not least, other elements like rhesus monkeys' age, their habitat's environment quality and individuals' differences should also be taken into consideration to the explanation. For example, different age results in various levels of metabolism which will influence an individual's levels of stimulation instead of the birth order. Another instance is the quality of their environment. A terrible habit threatening rhesus monkeys' survival will also increase the hormone cortisol level as a stimulus. Finally, the situation varies from individual to individual. Individuals' difference should also be taken into the explanation. Some individuals incline to be sensitive to the changing environment and react dramatically to the stimulus.

    In summary, the argument should explicate relevant experimental statistics, methods and environment. The author had better revaluate the original explanation by excluding all the other critical influential factors before drawing the final conclusion.

类型:托福大作文
题目:
Some people believe that university students should be required to attend classes. Others believe that going to classes should be optional for students. Which point of view do you agree with? Use specific reasons and details to explain your answer.
正文:
      Although there is a debate about whether attending classes should be optional, I agree with the point that students should attend classes to achieve their academic goals.
    To begin with, students need high GPA to prove their qualifications when they plan to find jobs or apply for graduate schools. No one can deny the truth that students attending classes tend to become more clarified about the requirements of those curriculums and usually have better average academic performance than those who do not, let alone in some cases the attendance itself can be a part of assessment when academic performance is valued. In many professors' view,  students incline to abuse their time and energy if they are absent from their classes.
    Moreover, students attending classes will benefit from face-to-face communication. When students feel puzzled about the lectures, they can propose their questions on the spot when professors want some instant feedbacks asking "Any questions?". Another case is when professors organize discussions in groups on certain topics, students will learn a lot from brain storming in mutual talks. Compared with studying alone with learning materials, you will gain prompt response from experts to settle your problems, as well as inspiring yourself and learning from others in a group discussion in a live lecture. Isn't that amazing?
    Last but not least, students will know better about discipline if attending classes is required. They are assumed to attend classes with no excuses according to the school rules. They should learn to follow the discipline which will make them accustomed to similar occasions after school no matter how much reluctant they truly are.
    In conclusion, students will benefit in many aspects if they are required to attend classes. Attending classes is a better choice for students to gain knowledge rather than a compulsory requirement to finish school.
