When and how much Those are the questions on the lips of investors, bondholders, and other Federal Reserve watchers. The Fed kept interest rates on hold at its Mar. 19 meeting. But the accompanying statement, in which the Fed abandoned its view that economic weakness was the greatest risk in the outlook, makes it clear that policymakers are thinking about the timing of rate hikes in order to bring monetary policy back to a neutral stance.
Even so, there are other factors that argue for some rise in short-term rates——perhaps as early as June, as Wall Street expects. While the Fed’s words lessen the chances of a rate hike at the May meeting, they do not set the criteria for a possible hike at the June 25-26 meeting.
The latest data seem to come down on the "evenly mixed" scenario. Businesses are backing off from last year’s feverish pace of stock-cutting, but domestic demand is holding up. Factories are busier in response to rising orders. In particular, the makers of tech equipment are boosting output at a rapid clip. At the same time, the wider trade gap in January suggests that some of the inventory swing is benefiting foreign producers. Keep in mind that a bigger trade gap subtracts from economic growth, but a rise in U. S. imports is necessary to give rise to a global rebound. That will eventually boost exports as well and help to better align monetary policy around the world.
The Fed’s decision to shift to a neutral stance was probably made easier by the latest good news on industrial production. Output at factories, utilities, and mines increased 0. 40% in February on top of a 0.2% January gain, which was first reported as a 0.1% loss. Manufacturing output rose 0.3% in each month, the best showing since mid-2000.
Surprisingly, the long-ailing tech sector is leading the charge. Tech production is growing at a double-digit annual rate in the first quarter, vs. almost no gain in the rest of manufacturing. But even that small rise in nontech manufacturing is a vast improvement from the steep declines of the previous six quarters. Just as tech is fueling the rebound in U.S. factory activity, tech imports are leading the import rise. Incoming shipments of tech goods jumped 14.6% in January, suggesting stronger capital spending.
As demand picks up, the Fed will want to remove itself from the equation of economic pluses and minuses. Step One was the shift in its view of the outlook. Step Two will be a series of rate hikes that will bring policy more in line with sustainable economic growth.
A:may fail to reflect the true state of U.S. economy. B:is necessary to give rise to a global rebound. C:may make it clear that the Fed changed its outlook. D:falls short of the expectations of businesspeople.

Face Masks May Not Protect from Super-Flu If a super-flu strikes, face masks may not protect you. Whether widespread use of masks will help, or harm,during the next worldwide flu outbreak is a question that researchers are studying furiously. No results have come from their mask research yet. However, the government says people should consider wearing them certain stations anyway, just in case. But it’s a question the public keeps asking while the government is makingpreparations for the next flu pandemic （大流行）.So the Centers for Disease Control and Prevention （CDC） came up with preliminary guidelines. "We don’t want People wearing them everywhere," said the CDC. The overall recommendation really is to avoid exposure.” When that is not possible, the guidelines say you should consider wearing a simple surgical mask if you are in one of the three following situations. First, you’re healthy and can’t avoid going to a crowded place. Second, you’re sick and think you may have close contact with the healthy, such as a family member checking on you. Third, you live with someone who’s sick and thus might be in the early stages of infection, but still need to go out. Influenza pandemics can strike when the easy-to-mutate （变异）flu virus shifts to a strain（菌株）that people never have experienced. Scientists cannot predict when the next pandemic will arrive, although concern is rising that the Asian bird flu might trigger one if it starts spreading easily from person to person. During the flu pandemic, you should protect yourself. Avoid crowds, and avoid close contact with the sick unless you must care for someone. Why aren’t masks added to this self-protection list? Because they can help trap virus-laden droplets flying through the air with a cough or sneeze. Simple surgical masks only filter the larger droplets （飞沫）. Besides, the CDC is afraid masks may create a false sense of security. Perhaps someone who should have stayed home would don（戴）an ill-fitting mask and hop on the subway instead. Nor does flu only spread through the air. Say someone covers a sneeze with his or her hand, then touches a doorknob or subway pole. If you touch that spot next and then put germy hands on your nose or mouth, you’ve been exposed. It’s harder to rub your nose while wearing a mask, so your face may get pretty sweaty under masks. You reach under to wipe that sweat, and may transfer germs caught on the outside of the mask straight to the nose. These are the problems face masks may create for their users. Whether people should or should not use face masks still remains a question. The general public has to wait patiently for the results of the mask research scientists are still doing. One of the concerns the CDC has is that
A:masks may give people a wrong assumption of being safe. B:the sick may not wear masks and go out. C:flu virus may spread via public transportation. D:healthy people may not know how to protect themselves.
