参考范文：According to the reading article, there are three reasons available to explain why humans’ brains get smaller. However, the professor casts doubt on these three explanations respectively by elaborating details.
Firstly, the passage refers that the unpredictable climate change is the one to blame for the the smaller size of people’s brains. In terms of this factor, the professor presents her opposite opinion by asserting that dating back to 20000 years ago when the climate change was frequent, brains were not shrinking. In this sense, even though the current climate is changeable, it cannot illustrate why humans’ brains become smaller in this phase.
Secondly, in the author’s opinion, the prevalence of grains which are rich in low-protein causes people’s brains to undergo shrinkage. Likewise, this theory is also contradicted by the professor. To illustrate, some countries like Australia did not start eating grain until recent centuries. Yet, like the brains of people from others countries, those of these areas also reduced in size.
Lastly, the lecturer admits the decrease of muscles. Nevertheless, it should not be responsible for brain shrink. It is easy to note that the rate of muscle shrink is lower that that of brain shrink. Thus, muscle shrink does not hold water.
考题回忆：People can solve important problems in their daily life on their own or with the help from families. The help from the government is not necessary. Do you agree or disagree?
参考范文：Problems are inevitable in everyone’s life so that support, no matter practical aids or spiritual encouragement, is by no means dispensable. It is noticeably seen that in the face of difficulties, people are more likely to resort to themselves or acquaintances. However, this does not mean than the help from government is negligible. In other words, it is definitely important for the government to provide help for its citizens.
First of all, the efficiency of solving problems can be substantially boosted by official assistance. To be specific, the government possesses absolute authority in legislation, supervision and regulation. Besides that, it can work collectively with different departments to support activities that benefit the public. For example, if pollutants caused by a given factory contaminate rivers, residents in the vicinity can report this case to the local government. It takes little imagination to predict that the government is bound to take measures to prevent the factory from releasing something less environment-friendly. Needless to say, the intervention of governments is more deterrent to the factory than the complaints from the public. In this sense, governments are well positioned to solve tricky public affairs.
In addition, the society will be more harmonious with the availability of the aids given by the government. Obviously, it is unwise for the government to create an image that it is far more superior to other social organizations. Otherwise, the gap between governments and common citizens will be widened, which will further distance the authorities from people. As a matter of fact, official are public servants, which means that they ought to work diligently and productively to assist people when harsh time arrives or help disadvantageous people. Presumably, such dedication is also supposed to stimulate the public to be wholeheartedly devoted to city construction and economic development.
In a nutshell, the government definitely plays an irreplaceable role in building social harmony and easing people from anxiety. From the angle of the authorities, they are supposed to show people that they are always there to save them from troubles. After all, every individual deserves the right to gain official aids.
