Hartley got to Central Station nearly an hour before his train was due to leave. A lifetime in the theatre had given him a healthy—indeed excessive(过分的)—sense of punctuality; a lifetime of unwanted cups of coffee, constant checking of the time, yet another turn around the clock before that all too often pointless, tiresome audition(试镜)．

Hartley was 75—pretty fit for his age, legs holding up, memory still ticking over nicely—though the occasions for punctuality were now rather fewer. But he was a creature of habit and couldn't change now.

He repaired to the restaurant, purchased a coffee and a blueberry muffin, tried and failed to find a litter-free table. The coffee was awful, the muffin was stale

—but the coffee was always awful, the muffin always stale. Hartley refused to let himself be annoyed. His visit to the city had not been without its pleasures. Lunch with an old actor-chum(好友), then a film—regrettably not utilizing(利用) his own talents—had rounded out an agreeable day.

Hartley was a good actor, although the calls on his talents were now infrequent. But really, he thought draining his awful coffee, he'd had a reasonably good career. Something to be proud of. But he'd never had that break-through part.

He headed for his platform. Just as the train was about to pull out a man ran down the platform, jumped aboard as the door slammed shut and sank into the seat next to Hartley.

“Cutting it a bit fine”， he said.

“Indeed”， Hartley replied. “A close run thing”．

The man—forty-ish, amiable looking—gave him an amused glance.

This brief exchange served as an adequate ice-breaker and they chatted their way through the outer suburbs and into the countryside. Having satisfactorily disposed of the sad state of the railways, country versus city living, his neighbour asked Hartley what he did—or had done—for a living.

Hartley hated telling people he was an actor. He was not ashamed of his job. Not in the least, but he had long tired of reactions ranging from “what have I seen you in” to “how do you learn all those lines”．

So in situations like this he simply selected an occupation from a former role. Bit risky, of course. You say you're a doctor and find yourself meeting the quizzical(疑问的) gaze of a heart surgeon. But he'd never been caught out and it was a harmless enough game, Hartley felt. It amused him, and he'd given some damn good performances too.

“I'm a lawyer”， he replied. “Retired several years ago. Property law. Bit of criminal stuff”．

The train was slowing down. The man glanced out of the window. “My station. I_had_you_quite_wrong_then”．

He stood and took down his briefcase from the overhead rack.

“Yes, I'd have said you were an actor. The voice especially. Still, lawyers are actors in a way, don't you think? Plenty of drama in a courtroom.”

The train drew into the station.

“I'm a film director. Casting a feature at the moment. You study faces. On the train. Everywhere. Always on the lookout. Anyway, enjoyed our chat. Bye.”

( )66. The writer refers to Hartley's sense of punctuality as “excessive”. Which of the following phrases fails to describe his sense of time?

A. Nearly an hour before his train. B. A lifetime of unwanted cups of coffee.

C. Another turn around the clock before that audition. D. A creature of habit that couldn't change now.

( )67. What did Hartley think of his not telling his occupation? A. Harmful to his acting career. B. Amusing despite the risk. C. Helpful to protect his identity. D. Upsetting when caught out.

( )68. What can we learn about Hartley's travel companion from the underlined sentence “I had you quite wrong then”？

A. He assumed Hartley had given another answer. B. He understood Hartley's profession was acting. C. He thought Hartley practiced a different profession. D. He mistook Hartley for another person.

( )69. The use of the word “Bye” at the end of the story ________． A. shows the readers how unexpectedly Hartley's career ends B. describes Hartley's shock on finding the man is a director C. confirms Hartley's lack of luck in spite of his acting skills D. proves the man will reconsider giving Hartley a chance to act ( )70. Which of the following can be the best title of the story? A. Acting up B. Employing Talents

C. Selecting an Occupation D. Casting a Feature

A backpack-carried digital nose that sniffs out simple explosive devices(IEDs) and other threats promises to ease checkpoint duty for troops stationed in hot spots around the world.

Developed by Scent Detection Technologies(SDT), a small privately owned company based

the

militarized

mininosc—trademarked

MN2000-MIL—detects and identifies IEDs, rigged vehicles(伪装的车辆) and other hazards by the vapors or traces particles(微粒) left on skin, machinery and personal belongings.

Soon to enter mass production, the MN2000-MIL is a ruggedized(强化的) version of the firm's MiniNose2000 designed for use by law enforcement and security personnel. It is a second-generation version of the firm's MN1000, which has been purchased by several Asian countries, including China, which introduced the system for the Beijing Olympics.

Like its former products, the system is based on company-patented High-Frequency Quartz Crystal Microbalance(HFQCM) technology that digitally imitates mammalian olfactory(嗅觉的) sense capable of learning to recognize new substance.

It works like a supersensitive digital nose able to detect very low nanolevel(纳米级) amounts of any source substance，” SDT Chief Executive Ofer Bengal said. “We then teach it to identify substances by matching them with a library of threats we've programmed into the machine.”

The entire analysis process, Bengal said, takes 8 to 26 seconds, depending on the substances.

Unlike other trace detection systems on the market, which are based on radioactive-source Ion Mobility Spectrometry technology, SDT's QCM-based system contains no radioactive parts.

“Ion Mobility Spectrometry systems are essentially radioactive，” Bengal said. “You need special licensing to sell them and specially trained personnel to service them. But we're using essentially green technology. You don't need trained
