Perhaps at one point in time, it was acceptable to start any letter or e-mail with “To Whom It May Concern.” 【小题1】 Starting your cover letter or e-mail for a job this way might give off the impression that you didn’t do your research on who you’re writing to. 【小题2】 After all, people who address other people by their names when writing and speaking to them tend to be more pleasant.

【小题3】 It can be used in letters of recommendation or reference, formal complaints（抱怨）made to a company, letters of introduction, and letters of interest.

Grammarly uses the example of needing to write a letter of recommendation, for a colleague who will have to make several copies to distribute to interviewers, 【小题4】 “In most cases, though, try to narrow your focus rather than cast a broad net,” notes Grammarly.”Ask yourself. Who does this e-mail concern? If you can honestly answer ‘Anyone, ‘then feel free to use “To Whom It May Concern.” （These are the things you should never say in your cover letter.）

If you do happen to find that using “To Whom It May Concern” is appropriate, don’t make grammar mistakes, for example, letters or punctuation. 【小题5】

Jobs that use both technical and creative thinking are among the fastest-growing and highest-paying ones, according to a new report from Burning Glass Technologies, a job market analytics (分析) company in Boston.

It studied millions of job postings to better understand the skills companies require. What they discovered was that many want workers with experience in such new abilities as big-data (数据) gathering and analytics, or design using digital technology.

Burning Glass came up with the term “hybrid jobs” to describe these kinds of positions, which require skills not normally found together. For example, these hybrid jobs might require people with skills in data science and advertising, or engineering and sales. “The jobs of the future don’t involve just one skill,” says Matt Sigelman, chief manager of Burning Glass.

The company expects general job growth of about 10% between 2018 and 2028, but the hybrid jobs by 21%. What’s more, hybrid jobs pay more than positions that call for a traditional set of skills. For example, a marketing manager mastering a database program gets paid 41% more than a traditional one, with an average yearly salary of $100, 000. Moreover, an engineer who improves her sales skills and becomes a consulting engineer for a software company can more than double her pay from $180, 000 to $400, 000.

While data shows that workers who fail to update their skills will be able to find fewer jobs, people in hybrid jobs are less likely to become out of date, with only 12% possibility of being replaced by machine, compared with 42% for general jobs, says Burning Glass. Hybrid jobs are mostly not beginner roles, so they mainly go to workers with years of experience and, most importantly, more training after leaving college. That means workers, bosses and educators will have to think about how to better prepare people for these roles.

In the fog of uncertainty about how new technology will change the way we work, policymakers around the world have flocked to the same idea. No matter what the future brings, they say confidently, we will need to upskill the workforce in order to cope.

The view sounds reassuringly sensible. If computers are growing smarter, humans will need to learn to use them to humans’ advantage. Otherwise, they may run the risk of being replaced by computers. 【小题1】 .

Research published by the Social Mobility Commission shows that workers with degrees are over three times more likely to participate in training as adults than workers with no qualifications. That creates a virtuous circle for those who did well at school, and vicious circle for those who did not. If the robots are coming for both the accountants and the taxi drivers, you can bet the bean counters will be more able to retrain themselves out of danger.

【小题2】 In the UK, the government introduced an “apprenticeship levy” a few years ago in an attempt to force employers to spend more on training. A surprising number have responded by sending their senior managers on “apprenticeships” at business schools.

It is no good criticizing employers for directing investments at their highly skilled workers. They are simply aiming for the highest return they can get. And, for some types of lower-paid work, it is not always true that technological progress requires more skills. The UK’s latest Employment and Skills Survey, which is performed every five years, suggests the use of literacy and numeracy skills at work has fallen since 2012, even as the use of computers has increased. The trouble is, when the computer makes your job easier one day, it might make it unnecessary the next. Many of those affected by automation will need to switch occupations, or even industries. 【小题3】

It is time to revisit older ideas. The UK once had an energetic culture of night schools, for adults to attend after their day jobs. These institutions have been disappearing due to funding cuts. But a revival of night schools could be exactly what the 21st century needs. 【小题4】 They can also explore interests they never had a chance to nurture before.

It is still not clear whether the impact of new technology on the labour market will come in a trickle or aflood. But in an already unequal world, continuing to reserve all the lifeboats for the better-off would be a dangerous mistake.
