"Indeed"George Washington wrote in his diary in 1785, "some kind of fly,or bug,had begun to eat the leaves before I left home." But the father of America was not the father of bug.When Washington wrote that, Englishmen had been referring to insects as bugs for more than a century, and Americans had already created lightning-bug(萤火虫). But the Enlish were soon to stop using the bugs in their language, leaving it to be the Americans to call a bug a bug in the nineteenth and twentieth centuries.
The American bug could also be a person, referring to someone who was crazy about a particular activity.Although fan became the usual term, sports fans used to be called racing bugs, baseball bugs and the like.
Or the bug could be a small machine or object, for example, a bug-shaped car. The bug could also be a burlar alarm, from which comes the expression to bug, that is, "to install(安装) an alarm". Now it means a small piece of equipment that people use for listening secretly to others' conversations.Since the 1840s,to bug has long meant "to cheat",and since the 1994s it has been annoying.
We also know the bug as a flaw n a computer program or other design.That meaning dates back to the time of Tomas Edison.In 1878 he explained bugs as "little problems and difficulties" that required months of stdy and labor to overcome in developing a successful product. In 1889 it was recorded that Edison "had been up the two previous nights discovering′a bug′ in his invented record player."
We learn from Paragraph 1 that
What does the word "flaw" in the last paragraph mean？
The passage is mainly concerned with
A group of 1,309 passengers boarded the MS Balmoral on Sunday, in Southampton, England, on a voyage to retrace (重走) the path of the Titanic. The Titanic was the biggest ship in the world when it sailed on its ill-fated first voyage on April 10, 1912. Of the 2,227 passengers and crew aboard, more than l,500 died. The ship, which was headed for New York City, carried the rich and famous on its first voyage. It also carried immigrants who were seeking a better life in America.
Relatives of people who sailed on the Titanic, historians, authors and people fascinated by the story of the unsinkable ship were on the Balmoral. They wanted to remember the Titanic and those who died on her first and last voyage.
The Balmoral was following Titanic’s original route from Southampton. First, the modern-day cruise liner docked (进港) in the port of Cherbourg, France, where the Titanic had picked up more passengers. On Monday afternoon, the Balmoral stopped in Cobh, Ireland, the Titanic’s last port of call before sailing to New York.
The Balmoral then sailed the North Atlantic Ocean to the location where the Titanic hit an iceberg. On Sunday, April 15, at 2:20 a.m. — the time the Titanic went down － passengers and crew held a memorial service. The next two days were spent in Halifax, Canada, where many victims of the Titanic are buried. Then, the Balmoral reached its final destination in New York City, where the Titanic was supposed to dock — but never did.
So far, several teams of divers have explored the site. They have recovered items such as dishes and silverware and put them on public display. And the Titanic and its passengers and crew have been remembered in books, movies and TV programs. But there’s a much more important contribution that the Titanic has given us. After she sank, lawmakers and ship builders made ships safer. It took a terrible tragedy to make ship travel safer for all.We learn from the first paragraph that _____.
| A．the Titanic sank on its second voyage |
| B．about 700 passengers of the Titanic survived |
| C．less than 2,000 passengers boarded the Titanic |
| D．all the passengers’ hopes of the Titanic lay in America |
Which of the following shows the correct route of the Balmoral?
a. Halifax b. New York City c. Cobh d. Southampton e. Cherbourg
| A．d-e-c-a-b | B．e-d-a-b-c | C．e-c-a-b-d | D．d-c-e-a-b |
What might be the most important contribution of the Titanic?
| A．Its site attracts many exploration teams. | B．It has made later ships more secure. |
| C．Some of its items are on public display. | D．More trips are planned to its site. |
What would be the best title for the text?
| A．The unsinkable ship | B．The Titanic today |
| C．The Titanic’s route | D．Sailing through history |
Maybe you’ve just invented something better than the iPhone or a solar-powered car. You don’t want anyone to steal your design. What should you do? Patent (申请专利) it! Patents are the best way to get credit for your work and help others continue advancing in that field. Here’s what you need to know.
A patent gives you the right to an invention. The patent protects its owner, which means the invention can’t be copied or sold without their agreement. In exchange, the owner must reveal information about the invention. This contributes knowledge that helps other inventors improve on their own research. A patent usually lasts about 20 years.
The first step to getting a patent is the application. The person applying must name the invention, explain its use and describe it clearly. The invention must be practical and contain some new characteristic — something that hasn’t been seen or used before. But not everything “new” can be patented. Many countries don’t allow patents on things like new concepts, scientific theories, medical procedures or substances already found in nature.
You may not be able to see patents, but they’re connected to nearly everything. There are patents on things you use every day, like plastic, medicine and your computer. There are patents on things that are unavailable on the market, too. Apple is well-known for its patents on potential products, such as the “iBike” or the “iKey”.
Of course there are also patents on inventions like this. Take the anti-eating face mask for example. This device locks around your head with a metal cage covering your mouth. You can breathe and speak, but you can’t eat!
Although many patented inventions can be failures, there’s plenty of room for success. So if you have a cool invention, try to patent it.Which of the following is NOT true according to the text?
| A．A patent can last for around 20 years. |
| B．Everything new can be patented. |
| C．Your invention is protected after you have applied for a patent. |
| D．Some patents are on the things that we use every day. |
We can infer that Apple’s iBike is _____.
| A．a popular product | B．a mere new concept |
| C．a famous brand in the world | D．a practical bike on the market |
The underlined word “device” in Paragraph 5 can best be replaced by “_____”.
| A．weapon | B．medicine | C．equipment | D．strength |
The purpose of writing this passage is to _____.
| A．advertise | B．persuade | C．warn | D．inform |

In so many ways, cyberspace(网络空间) mirrors the real world. People ask for information, play games, and share hobby tips. Others buy and sell products. Still others look for friendship, or even love.
Unlike the real world, however, your knowledge about a person is limited to words on a computer screen. Identity and appearance mean very little in cyberspace. Rather, a person’s thoughts—or at least the thoughts they type—are what really count. So even the shyest person can become a chat-room star.
Usually, this “faceless” communication doesn’t create problems. Identity doesn’t really matter when you’re in a chat room discussing politics or hobbies. In fact, this emphasis on the ideas themselves makes the Internet a great place for exciting conversation. Where else can so many people come together to chat about their interests?
But some Internet users want more than just someone to chat with. They’re looking for serious love relationships. Is cyberspace a good place to find love? That answer depends on whom you ask. Some of these relationships actually succeed. Others fail miserably.
Supporters of online relationships claim that the Internet allows couples to get to know each other intellectually first. Personal appearance doesn’t get in the way.
But critics of online relationships argue that no one can truly know another person in cyberspace. Why? Because the Internet gives users a lot of control over how others view them. Internet users can carefully craft their words to fit whatever image they want to give. And they don’t have to worry about what their “faceless” communication is doing for their image. In a sense, they’re not really themselves.
All of this may be fine if the relationship stays in cyberspace. But not knowing a person is a big problem in a love relationship. With so many unknowns, it’s easy to let one’s imagination “fill in the blanks.” This inevitably leads to disappointment when couples meet in person. How someone imagines an online friend is often quite different than the real person.
So, before looking for love in cyberspace, remember the advice of Internet pioneer Clifford Stoll: “Life in the real world is far richer than anything you’ll find on a computer screen.”
(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)We learn about a person in cyberspace only through _________________.
Why is the Internet a great place for exciting conversation?
What makes online love relationship often fail?
From the passage we can learn that the writer __________________________ looking for love on the Internet.
Holding a cell phone against your ear or storing it in your pocket may be dangerous to your health. This explains a warning that cell phone manufacturers include in the small print that is often ignored when a new phone is purchased. Apple, for example, doesn’t want iPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry’s manufacturer, recommends 2.5 centimeters.
If health issues arise from cell phone use, the possible effects are huge. Voice calls - Americans chat on cell phones 2.26 trillion(万亿)minutes annually - earn $109 billion for the wireless carriers.
Devra Davis, an expert who has worked for the University of Pittsburgh, has published a book about cell phone radiation, “Disconnect.” The book surveys scientific research and concludes the question is not settled.
Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
“Most cancers have multiple causes,” she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable（易受伤的）to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid（易吸收的液体）. No studies have yet been completed on cell phone radiation and children, she says.
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiation had damaged DNA in their brains.
Ms. Davis recommends using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen（腹部）.According to Ms Davis, brain cancer increase ____.
| A．among children | B．among old people |
| C．in the twenties | D．among pregnant women |
Why do children easily be affected by radiation?
| A．Because they haven’t grown up. |
| B．Because they are too young to protect themselves. |
| C．Because they use cell phones more often than adults. |
| D．Because their skulls are thinner and their brains are easily hurt. |
What can we conclude from the last paragraph?
| A．Pregnant women should keep cell phones away. |
| B．People should use cell phones in the correct way. |
| C．If you are a child, you’d better text than make phone calls. |
| D．When you use a cell phone, use a wired headset or the phone’s speaker. |
What does the passage mainly talk about?
| A．Be careful when using cell phones. |
| B．Don’t hold your cell phone against your ear. |
| C．Rats exposed to radiation have damaged DNA in their brains. |
| D．Low-energy radiation could damage cells that could lead to cancer. |
