Each year，half a million people die from brain aneurysms(动脉瘤)—when a blood vessel bursts in the brain.An aneurysm is a bulge in a blood vessel that can burst.If that happens in the brain，it can be deadly.For survivors，physical disabilities are often severe.They may include memory problems，loss of balance，trouble speaking and even blindness.But new technologies are increasing survival rates and reducing disabilities.
Beaumont Bacon is a survivor who makes light of her experience because she is a comedian.She uses humor to make others laugh.Now she's working on a new show.Michael Alexander is her doctor.He operated on Beaumont Bacon after her attack.“She had bleeding in the frontal area of her brain，so right above the eyes.The part that was in the brain was about maybe the size of an egg.So，that's a fairly large bleed.”
Ms.Bacon had a better chance at survival than most people because of Dr.Alexander.He directs the Neurovascular Center in Los Angeles.The center offers new technologies that include placing a catheter(导管) into an aneurysm，then threading wires to promote blood clots(血栓)．This technique reduces the chances of another burst blood vessel.“You don't have to open up the skull or open up the brain to do surgery.It's all done from inside the blood vessels.So it reduces the amount of blood loss，and the recovery is much faster.”
For Beaumont Bacon's recovery，the hospital worked to prevent problems commonly found in patients with a burst aneurysm.The problems include brain swelling that can shut down blood vessels.She spent a month in a coma(昏迷)—unable to communicate with doctors，friends and loved ones.But with a year of treatment，she recovered.Now，she is making people laugh. 1．What is the purpose of the text?
A．To give some practical advice. B．To tell an interesting story. C．To introduce a treatment technology. D．To present a research result.
答案 C [推理判断题。本文说明了一项治疗大脑动脉瘤的新技术，所以本文的写作目的是介绍一种新的治疗技术。故选项C正确。] 2．What do you know about aneurysms?

答案 C [细节理解题。根据短文第二段中的Now she's working on a new show.以及最后一段最后一句Now，she is making people laugh.可知，Beaumont Bacon在治疗后又重返工作岗位了。故选C。]

There were about 70 scientists working on a very important project.All of them
were really tired because of the pressure of work and the demands of their boss but everyone did not think of stopping their job.
One day，one scientist came to his boss and told him，“Sir，I have promised my children that I will take them to the exhibition so I want to leave the office at 5：30 pm.” His boss replied，“OK. You're permitted to leave the office early today.”
The scientist started working.He continued his work after lunch.He devoted himself to his work and when he finished his work，it was 8：30 pm.Suddenly he remembered the commitment he had made to his children.
He looked for his boss but he was not there.He closed everything and left for home.He was feeling guilty for having disappointed his children.When he reached home，he found the children were not there.
His wife was sitting in the hall and reading magazines.His wife asked him，“Would you like to have coffee or shall I serve dinner if you are hungry？” But the man asked，“Where are the children？” His wife replied，“You don't know? Your boss came here at 5：15 pm and has taken the children to the exhibition.”
The boss found him working seriously at 5：00 pm.He thought to himself，this person will not leave the work，but if he has promised his children they should enjoy the visit to the exhibition.So he took the children to the exhibition instead of the scientist.The scientist was deeply moved.
Do you know who the boss was? He was the leader of India's successful nuclear weapons and missiles(导弹) program and the former president of India—Dr.APJ Abdul Kalam.

5．The underlined word “commitment” in Paragraph 3 means ________． A．explanation C．expression
