Task 1
Directions: After reading the following passage, you will find 5 questions or unfinished statements, numbered 36 through 40. For each question or statement there are 4 choices marked A, B, C, and D. You should make the correct choice.
Today almost everybody is using a cell phone. Now people are able to carry their phones wherever they go. They are making phone calls, regardless of the time, place and situation. ',It is tree that technology is making our lives easier and more practical. For example, today parents like their children to carry cell phones so that they can reach them at any time.
From my point of view, the cell phone is necessary for emergency(紧急情况) situations and for business. It's also practical to avoid stress. Unexpected problems are always cropping up(突然出现), and using a cell phone can get rid of the stress they cause. For example, if you are in a traffic jam and know you will arrive late to work, you can call your boss and in form. him of the situation, overcoming this unexpected problem. Or, if you have a small car accident, you can call people to inform. them of your situation.
The widespread use of this device is amazing. It has become an important part of our daily lives. Whenever people forget their phones at home, they feel uncomfortable or unable to function. Another advantage of having a cell phone is that you can connect to the Internet and check your e-mail. In addition, you can access information such as news or movie theater schedules. Life is now fast and busy, and this high tech communication device has become a must. We need cell phones to keep up with the fast pace of life and the new demands of life in our ever changing world.
Cell phones can make our life ______.

A.easier
B.busy
C.fast
D.uncomfortable


【参考答案】

Task 2Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.Sparks created in a lab give off X-rays, scientists announced Monday.X-rays are a byproduct(副产物) of high-energy electron discharges in the Sun, in exploding stars, and even in lightning. Many scientists did not expect sparks alone to do the trick.Researchers at Florida Institute of Technology brought their equipment, which had detected X-rays in lightning, into the lab. Half the team expected to see X-rays and the other half did not.In sparks of 1.5 million to 2 million volts, the researchers indeed recorded X-rays that were remarkably similar to those produced by lightning.'This amazed us, It opens the door to answering really big questions about lightning by generating it in the lab,' said team member Hamid Rassoul. 'It also tells us that we have a lot'to learn about how even small sparks work.'X-rays are a form. of electromagnetic radiation, on a spectrum(频谱) that runs from radio waves on the low end to gamma rays on the high end and includes visible light, too.Scientists don't know why lightning spawns X-rays. They theorize it involves a 'runaway breakdown' of the air, in which electrons escape their normal connections and gain very large energies.'We didn't think X-rays could be made so easily in the air,' said study leader Joseph Dwyer. 'The results should allow for the detailed laboratory study of runaway breakdown, a mechanism that may play a role in thunderstorm electrification, lightning initiation and propagation, and terrestrial(地球的) gamma-ray flashes.'
