The U.S. Postal Service (USPS) continues to be in the red. It reported a net loss of $5.6 billion for 2016 alone, the 10th straight year its expenses have exceeded revenue. Meanwhile, it has the debts of more than $120 billion, mostly for employee health and retirement costs. There are many bankruptcies. Fundamentally, the USPS is in a historic squeeze between technological change that has permanently decreased demand for its bread-and-butter product, and a regulatory structure that denies management the flexibility to adjust its operations to the new reality.
Interest groups ranging from postal unions to postcard makers exert self-interested pressure on the USPS’s final supervisor—Congress (参议院), insisting that whatever else happens to the Postal Service, aspects of the present legal situation they depend on get protected. This is why repeated attempts at reform legislation (立法) have failed in recent years, leaving the Postal Service unable to pay its bills except by postponing vital modernization.
Now comes word that everyone involved—Democrats, Republicans, the Postal Service, the unions and the systems heaviest users—has finally agreed on a plan to fix the system. Legislation is moving through the White House that would save USPS an estimated $28.6 billion over five years, which could help pay for new vehicles, among other survival measures. Most of the money would come from a penny-per-letter permanent rate increase and from shifting postal retirees into Medicare. The latter step would largely reduce the financial burden of annually pre-funding retiree health care, thus addressing a long-standing complaint by the USPS and its union.
If it clears the White House, this measure will still have to get through the Senate—where someone is bound to point out that it amounts to the bare, bare minimum necessary to make the Postal Service stay afloat, not comprehensive reform. There’s no change to collective bargaining at the USPS, a major mistake considering that personnel accounts for 80 percent of the agency’s costs. Also missing is any discussion of getting rid of Saturday letter delivery. That common-sense change enjoys wide public support and would save the USPS $2 billion per year. But postal special-interest groups seem to have killed it, at least in the White House. The emerging consensus around the bill is a sign that legislators are getting frightened about a politically embarrassing short-term collapse at the USPS. It is not, however, a sign that they’re getting serious about transforming the postal system for the 2lst century.

The latest discovery in cat research reveals that the lovely animal seems to have a basic grasp on both the laws of physics and the ins and outs of cause and effect.
According to a newly published study, cats seem to be able to predict the location of hiding prey (猎物) using both their ears and an inborn understanding of how the physical world works.
In a recent experiment, Japanese researchers taped 30 domestic cats reacting to a container that a team member shook. Some containers rattled; others did not. When the container was tipped over, sometimes an object fell out and sometimes it didn’t.
It turns out that the cats were remarkably smart about what would happen when a container was tipped over. When an object did not drop out of the bottom of a rattling container, they looked at it for a longer time than they did when the container behaved as expected.
“Cats use a causal-logical understanding of noise or sounds to predict the appearance of invisible objects,” lead researcher Saho Takagi says in a press release. The researchers conclude that cats’ hunting style may have developed based on their common-sense abilities to infer where prey is, using their hearing.
Scientists have explored this idea with other endearing creatures: babies. Like cats, babies appear to engage in what’s called “preferential looking”—looking longer at things that are interesting or unusual than things they perceive (认知) as normal.
When babies’ expectations are violated in experiments like the ones performed with the cats, they react much like their animal friends. Psychologists have shown that babies apparently expect their world to obey the laws of physics and cause and effect as early as two months of age.
Does the study mean that cats will soon grasp the ins and outs of cause and effect? Maybe, Okay, so cats may not be the next physics faculty members at America’s most important research universities. But by demonstrating their common sense, they’ve shown that the divide between cats and humans may not be that great after all.
1.What do we learn from a newly published study about cats?
A.They can be trained to understand the physical world.
B.They have a natural ability to locate animals they hunt.
C.They know what kind of prey might be easier to hunt.
D.They are capable of telling which way their prey flees.
2.What may account for the cats’ response to the noise from the containers?
A.Their command of cause and effect. B.Their unusual sense of direction.
C.Their special ability to perceive. D.Their inborn sensitivity to noise.
3.What can we conclude about cats from the passage?
A.They have higher intelligence than the majority of animals.
B.They display outstanding abilities in hunting and hearing.
C.They can aid physics professors in their research work.
D.They interact with the physical world much like humans.

I learned about life from an ant farm. When I was seven years old, my family ____ an ant farm at home. First, we put clean sand in a thin glass box, and then we brought some ants from the backyard and placed them into the ____ home.
Shortly after the new ____ were dropped into the glass structure, they got to work making tunnels. I was amazed that each one knew ____what to do. After hours of staring, I realized that the ants had assigned jobs. With my mom ' s help, I kept a diary of what happened each day and ____ the ants. My favorite was the biggest , Cinderella. I drew a picture of her in my diary, which I still have .
One day a tragedy ____ the ant farm.While I was observing the ants , I had put my face so close to the structure that I accidentally ____ it over. Unfortunately, my carelessness caused all the tunnels to ____. Although the ants ____ their earthquake, one by one they began to die. I was ____ as I watched them give up their tunnel-building to carry the bodies to a corner of the farm. My mother reported that the ants were actually dying of "frustration"--- the feeling annoyed and disappointed as they couldn’t control the situation . They simply could not ____ the reality that their tunnels had been destroyed. Cinderella was the last to die ---she did so while carrying a dead ant on her back .
Although much time has passed, I still think of that ant farm. Mom had hoped it would teach me about the natural world, ____ it taught me much more.____ the years, I came to realize the ants were a study in the benefits of ____. Working together, they were able to create a(an) ____ world for themselves. I also learned that they should be____ for their hard work. Day in and day out, each labored at their task. The ant farm showed that teamwork and perseverance are indeed two key ____ for success. But there was an even larger lesson that I did not ____until recently: Disaster is a natural part of life, and must be ____. Unlike the ants, humans cannot give up when they face ____. Unlike the ants, we have to realize that if a tunnel caves in , we just have to build another.
