     On October 23, 2011, David Pologruto, a high school physics teacher, was stabbed (刺) by his

smart student Jason Haffizulla. Jason got straight A's and was determined to study medicine at Harvard,

yet this was his downfall. His physics teacher gave Jason a B, a mark Jason believed would undermine (损害) his entrance to Harvard. After receiving his B, Jason took a butcher knife to school and stabbed

his physics teacher.

     How can someone as smart as Jason do something so dumb? Studies show there is little or no

correlation between IQ and emotional intelligence.

     During my early university years, I regarded myself as an intelligent guy. I got good marks in

mathematics, physics, and other subjects. I thought such skills would surely give me a bright future.

After one year of study with decent marks, I began to see two major classes of students. The first

category of students turned up to few lectures, partied every weekend, enjoyed a great social life,

and did minimal work to pass courses. The second category of students were intelligent and hard

workers who got good grades and were very focused on their studies. Surely would these intelligent

and hard-working students find the great jobs before the other lazier class of students?

     Not so. Students are often shocked upon graduation that their qualifications are not as important as

they once thought. Graduates enter the workforce only to realize that co-workers hate them and less

intelligent people are the ones receiving promotions.

     Educational skills are useless in some industries when interpersonal skills are absent. You can have

great ideas, theories, and solve complex problems, but if you cannot effectively communicate in a

persuasive and exciting manner by relating to your fellow humans, you will face an uphill battle in

whatever challenges you encounter. It's not that people dislike you because of your intelligence; it's

that people dislike you because you're rude and not understanding. The intelligent person with poor

communication skills is insensitive or unaware of others' emotions.

1. Jason Haffizulla stabbed his physics teacher because _____  .

A. he was unfairly treated by his teacher

B. he was disappointed with his downfall  

C. he was not smart enough at studies

D. he got a worse mark than usual

2.We can infer from the third paragraph that the author  ____  in his early university years.

A. didn't think communication skills were as important as intelligence

B. didn't work hard

C. belonged to the first category of students

D. could keep a balance between social life and studies

3. Intelligent people are hated because _____   .

A. they can solve more complex problems

B. they can't settle the challenges they meet

C. they are envied for their intelligence

D. they are not understanding enough

4. The main purpose of the text is to tell us ____  .

A. the relationship between IQ and emotional intelligence

B. what kind of students can succeed in college

C. smart people may have poorer communication skills

D. intelligent students will meet more challenges at work
