Climate change. Small body can adjust to hot temperatures, so human brain shrinks in accordance with the body. |
过去温度也在变化，但人脑持续变大，所以人脑大小和气温无关 The size of human brain has nothing to do with temperatures. The brain keeps getting larger and large no matter temperatures go up or fall down. |

Changes of agricultural lifestyle. Smaller brain fits the diet when people start eating grain, with protein and vitamin in it. |
有些地区最近才有生活方式的改变，但人脑变小在全球几乎是同一时间发生，所以不可能。 Lifestyle appears in different times. There was no such trend in Australia and South Africa until recently. Yet the decline of human brain occurs at the same time around the world. So this assumption cannot be true. |

Changes in human muscle mass Human muscles have shrunk, which leads to the decline of muscle-controlling brain. |
肌肉群知识略有缩小，而人脑变小了很多，所以这不可能是主要原因。 The size of human muscle mass only decrease slightly, yet brain size gets much smaller. So this cannot be the major reason. |

Sample Answer:
Preference in methods of relaxation varies from person to person. Among these methods, staying indoors and reading or watching a movie is more popular than going outside and doing physical exercise. As for me, I prefer relaxing by reading a book and watching a movie.
Reading books or watching movies helps me relax physically. My days are busy with finishing all of my work, commuting to my office on the other side of the city, , and doing household chores that I do not have much time or energy to exercise. However, opening a book or playing a movie helps me slow down and restore my vitality. For example, when I read or watch a movie, I can sit back on a sofa or recline in bed. In this way, my muscles can rest. In contrast, when I exercise, I by no means rest or relax my body. In addition, I have to add washing my workout clothes to my already long list of chores.
Reading books and watching movies also helps me relax mentally. The tedious meetings, repeated routines and limited new tasks of my job makes me mentally exhausted. At these moments I like to enjoy an interesting story from a book or a famous movie. Then, all of the disturbing feelings, like boredom and depression, go away and I come away feeling inspired. For instance, I recently read the Biography of Steve Jobs and learned how this leader conquered adversity. In one of my favorite movies, The Shawshank Redemption, the main character Andy shows that no matter what difficulty we may confront, as long as we keep hope in our hearts, all the pressure will pass and the sun will still shine tomorrow.
Admittedly, exercising can help us relax to some degree. Football matches with co-workers, playing badminton in the backyard with family, and even a basketball game with some strangers could provide an escape from daily stress. However, viewed from a different perspective, doing physical activity has some potential risks. For instance, it is not uncommon to hear that people get physical injuries during physical exercise. What is worse, even some people have died suddenly from overstress their already tired bodies during exercise.
In conclusion, even though doing sports sometimes makes me feel more relaxed, I prefer reading a book or watching a movie when I want to relax.
