There’s a trend that more city people decide that they want to grow crops and raise some live-stock (家禽). After all, there are few things more satisfying than biting into a bunch of tender, red carrots you grow yourself, or a fresh egg from the backyard.

Most gardeners understand that the soil in big cities is often polluted with lead and know to get their soil tested. But most are pretty clueless about how to prevent other types of pollutants, like heavy metals and asbestos(石棉)from getting into their vegetables.

Part of the problem is that “there might be pollutants that gardeners can’t test for,” says Brent Kim, a program officer. Most soil tests look for lead, cadrniunt(镉)and arsenic(砷). But they don’t test things like chemicals left behind by cars, which might have escaped into the soil.

So if you’re thinking of staring an urban garden, Kim says, once you’ve found a plot of land, you should learn what’s now an empty plot or a backyard might once have been a parking lot, a gas station or a chemical ground. “Knowing its past will give you some idea about what might be in that soil,” he says.

“People tend to think raised beds are going to solve their pollution problem,” Kim says. But polluted soil could easily kicked onto your plants, especially if the beds are low to the ground.

“Another consideration is that you have to be careful about the materials that you’re using to build a raised bed,” Kim says. Recycling wood from an old construction site might seem like a good, eco-friendly idea. But that wood could be treated with chemicals you don’t want touching your fruits and veggies, Kim says. And it’s always a good idea to use gloves while gardening, and wash all your produce thoroughly.

“I see these urban growing spaces as these oases(绿洲)in the middle of these urban environments,” Kim says. “They bring communities together, and they help people save money on fresh produce. Urban growing spaces are amazing. Let’s keep doing this, but let’s do it safely.”

1.What does the underlined word “clueless” in Paragraph 2 mean?

A. unaware B. careless

C. helpless D. considerate

2.What should you do when starting an urban garden?

A. Build it on a parking lot B. Keep it low to the ground

C. Know the history of the ground D. Use recycled wood to build it

3.What do we know about the raise beds from the text?

A. They are free from some tests B. Their plants can be poisoned

C. They are environment-friendly D. Their materials are all recycled

4.What is the main idea of the text?

A. More fresh vegetables are produced by urban gardeners

B. Growing vegetables become a fashion in big cities

C. Big cities are short of soil for growing fresh produce

D. Urban gardeners may not realize the seriousness of polluted soil

Imagine that you’re looking at your company-issued smartphone and you notice an e-mail from Linkedln: “These companies are looking for candidates like you!” You aren’t necessarily searching for a job, but you’re always open to opportunities, so out of curiosity, you click on the link. A few minutes later your boss appears at your desk. “We’ve noticed that you’re spending more time on Linkedln lately, so I wanted to talk with you about your career and whether you’re happy here,” she says. Uh-oh.

It’s an awkward scene. Attrition (损耗)has always been expensive for companies, but in many industries the cost of losing good workers is rising, owing to tight labor markets. Thus companies are intensifying(增强)their efforts to predict which workers are at high risk of leaving so that managers can try to stop them. Tactics (策略)range from electronic monitor to sophisticated(复杂的)analyses of employees’ social media lives.

Some of this work may be a reason to let employees to quit. In general, people leave their jobs because they don’t like their boss, don’t see opportunities for promotion or growth, or are offered a higher pay; these reasons have held steady for years.

New research conducted by CEB, a Washington-based technology company, looks not just at why workers quit but also at when. “We’ve learned that what really affects people is their sense of how they’re doing compared with other people in their peer group, or with where they thought they would be at a certain point in life, says Brian Kropp, who heads CEB’s HR practice. “We’ve learned to focus on moments that allow people to make these comparisons.”

Technology also provides clues about which star employees might be eyeing the exit. Companies can tell whether employees using work computers or phones are spending time on (or even just opening e-mails from) career websites, and research shows that more firms are paying attention to these things. Large companies have also begun tracking badge swipes(浏览痕迹)---- employees’ use of an ID to enter and exit the building or the parking garage---to identify patterns that suggest a worker may be interviewing for a job.

1.From the first paragraph, we can infer Linkedln is___________.

A. an e-mail B. a job from the Internet

C. a professional social network D. a world-famous company

2.What’s the main idea of the second paragraph?

A. The cost of losing good workers is rising.

B. Companies are stricter with workers than before.

C. Measures have been taken to find the potential workers who want to quit.

D. Finding new jobs has been a trend for most workers.

3.According to the research by CEB, which of the following might be the most probable reason for workers to quit their jobs?

A. They don’t like their bosses. B. Workers are always doing comparisons.

C. Not seeing opportunities for promotion. D. To find a higher-paid job.

4.What is the author’s purpose in writing the text?

A. To make a review on a phenomenon. B. To tell us the leader’s concerns.

C. To show a new trend in the job market. D. To stress the role of new technologies.

Training for a marathon (马拉松) requires careful preparation and steady, gradual increases in the length of the runs. 1., buy the best-fitting running shoes you can find. No one can say which brand will work best for you or feel best on your feet, so you have to rely on your experience and on the feel of each pair as you shop. When you have found shoes that seem right, walk in them for a few days to double-check the fit. 2.. As always, you should stretch (伸展) at least ten minutes before each run to prevent injuries.

During the first week, do not think about distance, but run five minutes longer each day. 3., it is wise to take a day off to rest. But during the next week, set a goal of at least a mile and a half per run. 4.. After two weeks, start timing yourself. 5.. Depending on the kind of race you plan to enter, you can set up a timetable for the remaining weeks before the race.

A. After six days

B. For a good marathon runner

C. Before you begin your training

D. With each day, increase the distance by a half mile

E. If they still feel good, you can begin running in them

F. Time spent for preparation raises the quality of training

G. Now you are ready to figure out a goal of improving distance and time
