For this part， you are allowed 30 minutes to write an essay on how to balance academic study and extracurricular activities。 You should write at least 150 words but no more than 200 words。
It is generally agreed that academic study has been playing a crucial role in students’ life。 Nevertheless， we should not neglect the equal importance of extracurricular activities which can help us to build confidence and enhance overall abilities。
A number of factors might account for participating in both academic study and extracurricular activities。 With respect to academic study， one of the most common factors is to facilitate our academic competence。 There’s no doubt that study is the priority to students， and the academic performance， to a large extent， determines whether we can enter a prestigious school and get a decent job。 As for extracurricular activities， it is worth mentioning that it can supplement what we cannot learn from schools，
such as the ability of critical thinking， problem-solving and addressing interpersonal relationship。
In view of how to balance academic study and extracurricular activities， effective measures should be taken into consideration。 In my perspective， the most useful technique is to promote our efficiency。 Only if can we manage our time well， we can have more time to do the both things。 To be more specific， a to-do list is highly recommended so that we can draw a clear picture of what we are going to do and distribute time to academic study and extracurricular activities in a more effective and balanced way。 With the efforts concerned， the imbalance will no longer be a problem

Along with the development of society， more and more problems are brought to our attention； one of the most serious problems is how to reach the balance between work and leisure。 People have different attitudes towards the problem。
It is generally agreed that work has been playing an increasingly important role in our life， because we need to work to earn money for life。 But if people put too much time on work， their health conditions will be damaged and suffer from kinds of diseases。 The sub health among workers has attracted extensive attention of the society， which can be found in TV programs， newspapers， university classes and many aspect of our everyday life。 Thus， when people has a completed the work responsibility， they should spend some time on personal leisure。 Then， they could get some rest both physically and mentally， and have better conditions for tomorrow’s work。 However， if people invest too much time on leisure， their career developments may be affected and lost opportunities for a better life。
From what has been discussed above， we may safely draw the conclusions that people should ensure their leisure time after work。

mental conditions will be damaged and suffer from kinds of diseases。 The sub health of workers has attracted extensive attention of the society， which can be found in TV programs， newspapers， university classes and many aspect of our everyday life。 Thus， in addition to work responsibility， people should develop personal interests using spare time。 Then， they could enjoy the life and get rest both physically and mentally。 However， if people invest too much time on personal interests， their career developments may be affected and lost opportunities for a better life。
From what has been discussed above， we may safely draw the conclusions that people should focus on work responsibility during work time and develop personal interests on spare time。
In what is probably the craziest headline I have ever written， actual advances in livestock protection are happening by scientists painting eyes on the butts of cows。 The experiment is based upon the idea that farmers who are protecting their herd from lions， would shoot and kill lions in the efforts to protect their livestock。 While this makes a lot of sense， it resulting in many lion deaths that otherwise would have been unnecessary。 Researchers in Australia have been devising and testing a method of trickery to make lions think they are being watched by stamping eyes on cow butts。
This idea is based on the principle that lions and other predators are far less likely to attack when they feel they are being watched。 As conservation areas become smaller， lions are increasingly coming into contact with human populations， which are expanding to the boundaries of these protected areas。
Efforts like painting eyes on cow butts may seem crazy at first， but they could make actual headway in the fight for conservation。 “If the method works， it could provide farmers in Botswana – and elsewhere – with a low-cost， sustainable tool to protect their livestock， and a way to keep lions safe from being killed。”
Lions are primarily ambush hunters， so when they feel their prey has spotted them， they usually give up on the hunt。 Researchers are currently testing their idea on a select herd of cattle。 They have painted half of the cows with eyes and left others as normal。 Through satellite tracking of both the herd and the lions in the area， they will be able to determine if their psychological trickery will work to help keep farmers from shooting lions。
