Dear iPhone 4 Users,
The iPhone 4 has been the most successful product in Apple’s history. It is the best smartphone ever, and most users have told that they love it. So we were surprised when reading reports of reception (信号接收) problems, and we immediately began researching them.
To start with, holding tightly（紧紧地）almost any mobile phone in certain ways will reduce its reception by 1 or more bars of signal strength. This is true of iPhone 4, iPhone 3GS, as well as many other phones. But some users have reported that iPhone 4 can drop 4 or 5 bars when tightly held in a way. This is a far bigger drop than normal, and as a result some have said the iPhone 4 has a faulty antenna(天线) design.
Upon research, we find that the formula（公式） we use to calculate how many bars of signal strength to display is totally wrong. Our formula usually mistakenly displays 2 more bars than it should for a given signal strength. The big drop in bars is because the high bars were never real in the beginning.
We will give a free software update to correct the formula. This software update （软件升级）will also be available for iPhone 3GS. If you are not fully satisfied, you can return your undamaged iPhone to any Apple Retail Store or the online Apple Store within 30 days of buying and get all your money back.
Thank you for your patience and support.

Eddie Morra, the main character in the movie Limitless can do all these things. But he isn’t Superman or Harry Potter. Eddie has taken pills called NZT.
Thriller Limitless came out in China on October 13. In the movie, Eddie is faced with “writer’s block”. He hasn’t written a single word of a novel, and his deadline has passed. And there’s more bad news: his girlfriend breaks up with him. By chance, Eddie runs into a relative who is a drug dealer. He gives Eddie some pills called NZT that allow people to make use of 100 percent of their brains. With the magic pills, Eddie’s life changes completely. He can recall everything he has ever read, seen or heard. He gains a sixth sense that allows him to predict future events. He even becomes a kungfu master by simply memorizing actions in Bruce Lee’s movie.
Before long he has finished his novel, won back his girlfriend and stepped into the financial world. He becomes rich incredibly quickly and is soon employed by a powerful Wall Street company. However, bad side effects are just around the corner. The effects of the pill last for only one or two days, and Eddie has to find more supplies of the pills. Meanwhile, the pills start to have other effects on him. Eddies’ mind loses the ability to control the actions of his body. What does destiny hold for him? Will he be able to go back to his normal life?
“Eddie’s fate turns out to be a barbed （讽刺的） joke… a sharp-eyed comic fable for an age of greed (贪婪)and speed.” writes A. O. Scott, a movie critic with the New York Times.
The drug isn’t real-----yet, some researchers say such memory-enhancing drugs might not be far off. Would you take such a pill despite its side effects? Is the ability to remember everything a blessing or a curse?
【小题1】Which of the following happened to Eddie after he took the pill?

  Environmental protection is frequently talked about nowadays. The authorities are doing their best to arise the public awareness of the vital importance of the environmental protection. This issue is, indeed, worth following up.
Environmental protection is closely related not only to our personal life, but also to the entire human race and the world’s further development. For one thing, the environment, in a narrow sense, determines the quality of our individual life. The air we breathe, the water we drink, the food we eat, etc. , all come directly from the environment. If they continue to be contaminated, we may have neither clean water, nor healthy food. For another thing, in a broader sense, the environment plays a decisive role in fate of mankind. As is known to all, the earth, up to now, is human being’s only dwelling place. We can expect that some day we will live on another planet, but I doubt that this day will come earlier than the day when the earth becomes a globe of waste, if we keep damaging the environment. Finally, the environment is essential to the further development of the world. Extensive industrialization, which has brought about all the convenience and facilities we enjoy today, has been depending on the comprehensive exploitation of the earth’s natural resources found in the environment. If we do not protect the environment properly, further development cannot be guaranteed. In a word, to protect the environment is an urgent task.
Nevertheless, environmental protection is indeed a demanding task. Many people are still, either unconscious of the urgency of the task or deliberately damaging the environment for the interests of their own. Hence, we should adopt severe measures to prohibit people from doing more harms to the environment. Meanwhile, we need to make the gravity of the present situation known to all. In other words, punishment and instruction should be equally emphasized. Only in this way can we look forward to a cleaner and greener world.
