Initial efforts focused on the exterior of the tower, but in the next few months, other, more radical techniques will be tried to halt the tower’s lean. There methods will be applied directly to the soil, modifying the tower’s footing. Large-scale filed trials are now under way at the Miracle Square, where the tower stands, but all work is being done far from the monument itself to guard against the possibility that altering the ground too close to the tower could eventually damage the building.
    The ultimate goal is not to straighten the tower. Because the structure tilted in different direction during the early stages of construction, it became curved like a banana and will never stand truly upright. Instead, the experts and engineers hope to ease its top back some 10 or 20 centimeters. With luck, their efforts will keep the landmark standing into the next century, when a new generation of scientists will tackle the 800-year-old problem of the leaning tower of Pisa.

1．Should College Students Be Allowed to Get Married?
There is no denying the fact that it is a hotly debated topic today whether college students should be allowed to get married. Some time ago, the ban was lifted by some universities on students getting married. To this people’s attitudes differ sharply. Some hold the positive view. They say that most college students are adults and that it is a basic right for those who have reached the appropriate ages to get married.
Many others, however, hold the opposite view. They claim that the university or college is a place to study instead of a community to lead a family life. Allowing college students to get married would adversely affect their study. For instance, they would spend too much time attending their family and love, unable to concentrate on their school work.
As far as I am concerned, I believe that it is OK to allow college students to get married. Anyway, this is their freedom. Actually, we don’t have to worry too much because facts have shown that most college students would choose not to get married in the face of such fierce competition and heavy school work. 
(或 As far as I am concerned, I believe that college students should not be allowed to get married. Though mostly adults, they are actually immature psychologically. Their wish to get married is, more often than not, impulses. Besides, as students, they are not ready to support a family financially.

2. Preferable Work
Some people prefer to work with people. Working with people usually makes one feel interesting and efficient. At the same time, it can give people power and competition and provides rivalry which can be a very effective motive in improving one's ability. In addition, people can get better ideas by way of consultation and conference with other people.
On the other hand, other people like jobs which mainly involve with objects or machine. They probably think that working with objects or machine will provide more peace and quiet. Under such peaceful conditions, one can do more practical work, improve one's skill and make technical renovations.
