Michael Jackson, the American pop legend, died of a cardiac arrest(心脏骤停) in a Los Angeles hospital last night, just weeks before he hoped to resurrect(复活) his four-decade long career with a series of sold-out shows in London. The pop superstar was taken to the University of California at Los Angeles medical centre last night, and doctors tried resuscitation(使苏醒,使复活) in the ambulance. He did not regain consciousness and was reported dead about three hours later.

"My brother, the legendary King of Pop, passed away on Thursday 25 June at 2.26pm," his brother Jermaine said, "We believe he suffered a cardiac arrest at his home, however the cause of his death is unknown until the results of the autopsy(验尸) are known. The personal physician who was with him at the time attempted to resuscitated him."

A spokesman for the UCLA medical centre said, "When he arrived at hospital at approximately 1.14pm, a team of doctors attempted to resuscitate him for a period of more than one hour, they were unsuccessful." Police said they were investigating, which is standard procedure in such cases.

Jackson's death brought a tragic end to a long decline from his peak in the 1980s when he was music's greatest all-around performer, a uniter of black and white music who shattered the race barrier on MTV. His 1982 album Thriller, which included the blockbuster hits Beat It, Billie Jean and Thriller is still the best-selling album of all time, with an estimated 50m copies sold worldwide.

The world famous entertainer had planned a series of 50 concerts in London from 12 July. Although in the last two decades his reputation was destroyed by charges of child molestation(骚扰) and his fantastic public behavior, all tickets were sold within hours, proving the King of Pop had enduring appeal.

49.   Where did Michael Jackson die?

C. On the stage in London.                  D. In an ambulance to hospital.

50. What caused Michael Jackson to die according to Jermaine?

A. Heart disease.                        B. It’s unknown before the results of the autopsy.

C. Working too hard.                         D. His personal physician’s improper treatment.

51. Why were the police involved in investigating the death of Michael Jackson?

A. Because they believed he was murdered.

B. Because it was standard procedure in such cases.

C. Because Michael Jackson died suddenly.

D. Because his brother was suspicious of the truth of his death.

52. It can be inferred that Michael Jackson was ___________.

A. a King of Pop with good reputation.

B. a King of Pop still playing on the stage before death.

C. indeed a bad man with fantastic public behavior.

单项选择题

Congress began 2010 with a bad case of legislative deja vu. Last year, it approved a $ 787 billion stimulus package meant to "create or save" millions of jobs. President Obama says the stimulus has saved or created as many as 2 million jobs so far. But even if that highly optimistic figure is true, in the real world, over 3 million jobs have been lost since the stimulus was signed into law--a dismal feat all financed with enormous debt. Now Congress is working on another stimulus package, but they’re calling it a jobs bill. In December, the House passed a $174 billion "Jobs for Main Street Bill" that would use federal dollars to fund job-creating infrastructure projects, while extending unemployment benefits. Sound familiar

Unemployment remains at about 10% and state unemployment insurance funds are running out of money. While the Obama administration works to artificially inflate the number of jobs, the unemployed face diminished opportunities and income security. By 2012, 40 state unemployment trust funds are projected to be empty, requiring $ 90 billion in federal loans to continue operating Normally, state unemployment benefits pay jobless workers between 50 and 70% of their salaries for up to 26 weeks. But during this recession, what would be wrong with that Everything. The state-federal unemployment insurance program (UI) is an economic drag on businesses and states. And it’s a poor safety net for the unemployed.

UI, a relic of the Depression, fails workers when they need it most. UI trust funds depend on a state- levied payroll tax on employers. During boom years, these funds are generally flush. But during recessions, they can get depleted quickly. The bind is that to replenish their UI fund, states have to raise payroll taxes. That hurts the bottom line for most businesses. Passed on to workers as a lower salary, high payroll taxes discourage businesses from hiring. During steep recessions, states face a fiscal Catch- 22: Reduce benefits or raise taxes. To date, 27 states have depleted their UI funds and are using $ 29 billion in federal loans they’ll have to start repaying in 2011. Other states are slashing benefits. While federal guidelines recommend that states keep one year’s worth of unemployment reserves, many states entered the recession already insolvent. When federal loans are exhausted, the only option left is higher payroll taxes--a move sure to discourage hiring and depress salaries.

The increasingly small and uncertain payouts of UI are the opposite of income security. The effect of UI’s eight-decade experiment has been to condition workers to save less for a "rainy day" and instead rely on a system that provides no guarantee. UI limits personal responsibility to save; gradually, individuals find themselves in financial peril. Real reform requires putting employees in charge with individual private accounts and getting the government out of the business of creating illusionary safety nets.

Unemployment Insurance Savings Accounts (UISAs), by contrast, give workers control of their own income, eliminating the negative effects of the UI program on businesses and budgets. Adopted by Chile in 2003, UISAs are also financed via a payroll tax on individual workers and employers. The difference is the money is directly deposited into the individual worker’s account. Basically a form of forced savings, UISAs allow individuals to draw on their own accounts during periods of unemployment and roll unused funds into their savings upon retirement. With the burden reduced on employers, wages rise, leading to greater contributions to the individual’s fund. The federal government is removed from the picture. And all workers are guaranteed a savings account upon retirement.

UISAs liberate workers from uncertainty and improve incentives. When unemployed workers must rely on their own funds rather than the common fiscal pool, they find jobs faster. Congress’s repeated extensions of the current UI program may be well intended, but they may also be counterproductive. Like any deadline extension, additional jobless benefits diminish the job seeker’s urgency, all at taxpayers’ expense.

Today, expanded UI benefits mean higher state payroI1 taxes, which make it harder for employers to expand hiring or raise wages. UISAs, on the other hand, make the payroll tax on business part of the employer’s investment in an individual worker, rather than a penalty for doing business. In 2010, it’s time to say goodbye e to the problems created by broken policies. Congress should start this decade with a promise for true economic freedom: Let businesses create jobs and let workers keep what they’ve earned.

According to the passage, UI ().

A. was established in the most recent economic crisis

B. has been mainly funded by payroll tax on employees

C. would not be exhausted even during steep recessions

D. would not motivate the unemployed to seek jobs urgently
