The Cost of Thinking

Though humans have many differences，they share several typical characteristics（特征），such as large brains and the ability to walk upright on two legs.

The first human characteristic is humans' large brains. Mammals（哺乳动物）weighing sixty kilos have an average（平均）brain size of 200 cm'. Modern man has a brain averaging 1，200~1，400 cm3. The larger，the better？Unluckily，that is not the case.

The bigger our brain is，the more energy is needed. It's not easy to carry around，especially when boxed inside a large skull（颅骨）. It's even harder to provide energy. In modern man，the brain is about 2-3% of total body weight but it needs 25%of the body's energy when the body is at rest. But the brains of apes（类人猿）require only 8% of rest-time energy. How did early humans pay for their large brains？Firstly，they spent more time in search of food. Secondly，their muscles（肌肉）grew smaller and weaker.

Another human characteristic is that we walk upright. Standing up，it's easier to find food or enemies. In addition，their arms that are unnecessary for moving around are freed for other purposes，like throwing stones or showing body languages. As a result，humans can perform very different tasks with their hands.

Yet walking upright has its downsides. The bones（骨头）have to support a large skull. That causes backaches and painful necks. A large brain makes many advantages. It seems that these have made humans the most powerful animal on earth. But humans enjoyed all of these advantages for a full 2 million years during which they were weak，small and not important.

A: Hi！What are you doing？Is it a diary？

B: No. Recently I haven't kept diaries any more. I'm listing something when we choose a future career（职业）. You know, we are in Grade 9, we'll go to senior high school（高中）this year. Taking future career【1】makes me think about this earlier.

A: Let me see. Wow, you think Salary（工资）should, come first. There's no【2】that making money should be considered. But don't you think【3】is more important? For example, if you have a job that you don't like, you will get tired of this job quickly.

B: That sounds reasonable. I still think how much money you make shows how much your work is【4】

A: As for me, the sense of achievements in the job will be the happiest thing. People's choice may be influenced by their 【5】too. Choosing a job that you are not good at is not wise.

B: That's to say I should choose science in senior high school. I am good at chemistry and I always want to be a pharmacist（药学师）. What do you choose？

A: I'm not sure. I haven't decided yet. My dad【6】studying architecture major（建筑学）in the future, but I am not interested in that. I love a kind of life【7】is full of the unexpected tasks. I hate the life that we can predict what will happen tomorrow.

B: Wow, it's not like you. You seem quiet in your【8】life.

A: That's not true. I am much stronger than what I look like. I am ready to face all happenings in the future. 【9】we choose,we will probably achieve it as long as we take action right now and【10】to it.

B: You're right.

There was once a famous scientist who made several important discoveries. Once he was asked how he was able to be so creative. He replied that it all came from an experience he had with his mother at the age of 2. He was trying to take a bottle of milk out of the fridge. But the bottle was too slippery and he dropped it. The kitchen was covered in milk.

When his mother came into the kitchen，instead of shouting at him or punishing him，she said，"Robert，what a great and wonderful mess you have made！I have never seen such a huge puddle（水坑）of milk. Would you like to play in the milk for a few minutes before we clean it up?"

So he did. After a few minutes，they cleaned it up together. Then his mother said，"This was a failed experiment（实验）in how to carry a big bottle of milk with two small hands. Let's go out in the backyard and fill the bottle with water and see if you can find a way to carry it without dropping it.”

The little boy learned that if he held the bottle at the top near the mouth with both hands，he could carry it without dropping it. What a wonderful lesson！

The scientist then added that it was at that moment that he knew he didn't need to be afraid to make mistakes. He learned that mistakes are just chances to learn something new which is after all, what scientific experiments are all about. Even if the experiment doesn't "work", we can still learn something valuable from it.
