Dear Customers,
I feel quite pleased to announce Amazon Prime, our latest membership program, which provides “all-you-can-eat” express shipping. It’s simple: for a directly yearly membership fee, you get unlimited two-day shipping for free on over a million in store items. Members also get overnight shipping for only $3.99 per item—order as late as 6:30PM ET.
Amazon Prime takes the effort out of ordering: no lowest purchase and no combining orders. Two-day shipping becomes an everyday experience rather than an occasional excitement.
We are offering Amazon Prime membership at the introductory price of $79 per year, which includes sharing the benefits with up to four family members in your household. Considering that we normally charge $9.48 for two-day shipping on a single book and $ 16.48 for overnight, many of our customers will find the program very rewarding. It works across books, DVDs, music, electronics, kitchen, tool, health, personal care, etc, etc.
We expect Amazon Prime to be expensive for Amazon.com in short term. In the long run, we hope to earn even more of your business, which will make it good for us too. We hope you enjoy our latest transformation(转变).
You can sign up for membership with one click HERE.
Sincerely,
Jeff Bezos
Founder & CEO

Psychologist George Spilich and colleagues at Washington College in Chestertown, Maryland, decided to find out whether, as many smokers say, smoking helps them to “think and concentrate.” Spilich put young non-smokers, active smokers and smokers deprived (被剥夺) of cigarettes through a series of tests.
In the first test, each subject (试验对象) sat before a computer screen and pressed a key as soon as he or she recognized a target letter among a grouping of 96. In this simple test, smokers, deprived smokers and nonsmokers performed equally well.
The next test was more complex, requiring all to scan sequences of 20 identical letters and respond the instant one of the letters transformed into a different one. Non-smokers were faster， but under the stimulation of nicotine (尼古丁), active smokers were faster than deprived smokers.
In the third test of short-term memory, non-smokers made the fewest errors, but deprived smokers committed fewer errors than active smokers.
The fourth test required people to read a passage, then answer questions about it. Non-smokers remembered 19 percent more of the most important information than active smokers, and deprived smokers bested those who had smoked a cigarette just before testing. Active smokers tended not only to have poorer memories but also had trouble separating important information from insignificant details.
“As our tests became more complex.” Sums up Spilich, “non-smokers performed better than smokers by wider and wider margins” He predicts, “smokers might perform adequately at many jobs until they got complicated. A smoking airline pilot could fly adequately if no problems arose, but if something went wrong, smoking might damage his mental capacity.”
1.The purpose of George Spilich’s experiments is _______.
A. to test whether smoking has a positive effect on the mental capacity of smokers
B. to show how smoking damages people’s mental capacity
C. to prove that smoking affects people’s regular performance
D. to find out whether smoking helps people’s short-term memory
2.Which of the following statements is true?
A. Active smokers in general performed better than deprived smokers.
B. Active smokers responded more quickly than the other subjects.
C. Non-smokers were not better than other subjects in performing simple tasks.
D. Deprived smokers gave the slowest responses to the various tasks.
3.We can infer from the last paragraph that _______.
A. smokers should not expect to become airline pilots
B. smoking in emergency cases causes mental illness
C. no airline pilots smoke during flights
D. smokers may prove unequal to handing emergency cases
