Malaysia Airlines Flight MH370, after its shocking disappearance, has caught the attention of millions around the world as the search for the airplane and its passengers and crew continues. What happened to the flight’s 239 passengers and crew after the plane left Kuala Lumpur on Saturday? It is becoming an increasingly desperate question as the days pass.

But it’s hardly the first mystery of its kind. Here are some half-solved and unsolved airline mysteries that kept investigators clueless for years.

Air France Flight 447: An Airbus A330 flight from Rio de Janeiro to Paris plunged into the Atlantic Ocean in 2009, killing all 228 passengers and crew on board. But it took a full five days for search and rescue teams to find the wreckage（殘骸）and another three years for investigators to report that ice crystals had caused the autopilot (自動(dòng)駕駛儀) to disconnect. The bodies of 74 passengers remain unrecovered.

Amelia Earhart: Top pilot Amelia Earhart disappeared in her twin-engine monoplane Electra over the Pacific Ocean in 1937 in an attempt to travel around the globe. No sign of her plane was ever found even after a multi-million dollar search effort, and Earhart was officially declared dead in 1939. m.e-deep.com.cn考后首發(fā)

Flying Tiger Line Flight 739: A U.S. military flight left Guam in 1962 with more 90 personnel headed for the Philippines, but it never arrived. The pilots never issued a distress call, and 1,300 people involved in the U.S. military search never found any sign of wreckage.

British South American Airways: It took more than 50 years to find any trace of the 11 people aboard a 1947 flight that disappeared in the Andes Mountains. A pair of Argentineans rock climbers discovered engine wreckage in the Andes in 1998, and an army expedition later found human remains as well.

Uruguayan Air Force Flight 571: A flight headed to Santiago, Chile carrying 45 passengers and crew crashed into the Andes Mountains in poor weather in 1972, killing twelve people. In the meantime, eight were killed in an avalanche (雪崩) that hit the plane’s wreckage where they were taking shelter, and the rest stayed alive by eating the flesh of the dead before they were finally found more than two months after disappearing out of the sky.

C

A couple of days ago, as the test results came out, my son and a group of his 13-year-old friends piled into the back seat of my car, ready for the last-day-of-school party at McDonald's. “Jack got a laptop for getting straight A's, and Laurie got a cell-phone,” one boy said. “Oh, yeah, and Sarah got an iPad, and she's only in third grade,” said another. “And how about Brian? He got $10 for each A.”

I suddenly became concerned. These payoffs might get parents through grammar school, but what about high school and beyond? What would be left after the electric guitar, the cell-phone, and the DVD player?       

I saw the road ahead: As the homework load increased, my income would decrease. I saw my comfortable lifestyle disappear before my eyes — no more of those $5 bags of already-peeled organic carrots. No more organic anything!            

I started to feel surprised and nervous. Would every goal achieved by my two children fetch a reward? A high grade point average? A good class ranking? Would sports achievements be included in this reward system: soccer goals, touchdowns? What about the orchestra? Would first chair pay more than second? I'd be penniless by eighth-grade graduation.

“We never paid anything for good grades,” said my neighbor across the street, whose son was recently accepted at MIT. “He just did it on his own. Maybe once in a while we went out for pizza, but that's about it.”

Don't you just hate that? We're all running around looking for the MP3 player with the most updates, and she’s spending a few dollars on pizza. She gets motivation; we get negotiation. And what about the primary grades? What do these students get? “When the teacher asked if anyone got rewards for good grades, everyone in my class raised their hands and said they got ice cream cones ,” said one third-grader.

28. What’s the best title for the passage?

　A. Tips on Paying Kids for Good Grades

　B. New changes in Paying Kids for Good Grades

　C. Good Grades Mean Good Rewards

　D. Don't Pay Kids for Good Grades

29. What does the underlined sentence in the third paragraph probably mean?

　A. Taking care of my children would influence my work.

　B. I would spend less money on my children's good grades.

　C. More rewards would be needed as my children grow up.

　D. Reducing my children's homework load would cost me a lot.

30. It can be inferred from the passage that ________. 

　A. if you buy children pizza as a reward, they will work harder

　B. if you pay kids for good grades, they will take it for granted

　C. children will not ask for rewards when they enter high school

　D. good grades won't help kids make great progress in the future

31. The author takes her neighbor as an example to show _______.

　A. pizza is the best way to motivate children

　B. it is necessary to reward children for their good grades

　C. getting rewards for good grades is common nowadays

　D. rewards are not the only way to encourage children

Since American students have been introduced into the era of the Massive Open Online Course, the opportunity for cheating appears greater than ever. The all-knowing Google search engine is within easy reach. So how can a teacher handle such a large number of examinees so far away, let alone searching out cheaters taking tests across the Internet?

Using technology, of course. While special services via webcam (攝像頭) and cheating detecting software have been developed now, Mettl, an online company, has developed advanced techniques for netting cheaters, which the company claims are even more reliable and easier to use. Whatever small attempt to cheat, he or she will be found out.

Mettl has adopted a mass of technologies on its test-taking platform, creating a mini monitoring state in an exam. Here’s how it works: A test-taker signs on to Mettl and selects his／her exam from the site’s library of pre-loaded tests. Facial and keystroke recognition technology confirm the person that has signed in is the very person, and the system records both the test-taker (through the webcam) and the test-taker’s screen throughout the test.

Mettl’s technology uses the test-taker’s webcam to detect how many people are using the computer. Soon, it will track eye movement well enough to sense whether the test-taker is looking away from the screen, perhaps to consult a smart phone or a friend in secret. Mettl also monitors the test-taker’s screen and can detect when the test-taker has changed a computer or moved from the test. The system will soon be able to record sound, detecting whether the test-taker is talking or being talked to.

   If any wrongdoings are detected, the system flags the incident and reports it back to the test’s administrator. This can bring any number of things, depending on the test-giver’s wishes: a complete shutdown of the exam, a warning message that appears on the test-taker’s screen, even human instructions from the control center. 

  Mettl is hoping its technology will help it break into the country’s big MOOC markets.

32. From the first paragraph we can infer that         .

A. MOOC has replaced the traditional form of education

B. Teachers should be stricter in dealing with cheating

C. Preventing online cheating is a harder job

D. Google is a software designed for cheating

33. How can Mettl help to get rid of cheating online?

A. By equipping teachers with cameras.

B. By asking test-takers to sign in.

C. By providing different tests at a time.

D. By recording the test-takers’ behaviors.

34. We can conclude from the passage that the technology of Mettl is    in the MOOC era.

A. unreliable B. promising C. wastefulD. instructive

35. Which part of a newspaper does the article come from?

A. Health       B. Entertainment  C. EducationD. Culture

               How to Write A Good Letter

Do you want to write a good letter? Here are two main secrets. Don't try to be fancy. Don't try to impress your reader. You will be successful if you follow these seven Cs.

     Clear. Use short, direct sentences.    36    Talk as if the reader were right there with you. Above all, don't use an introduction.

     Complete. Don't leave your points loose.    38    This is good organization too.

     Courteous. Be friendly rather than overly casual. Present your information nicely even if you are complaining about something. In all letters, treat others as you want them to treat you.

     Concise. Make each point as clearly and briefly as you can.

     Conversational. This is really the secret of good writing.    39    Such a letter has a natural, friendly tone. Let your personality come through naturally.

     Considerate.     40    Write about what you believe the reader needs or wants to know. Try to be helpful. This will build good feeling toward you.
