The crash made the papers. April Brown was charged with drunken driving and driving without a license. The wake began on Nov. 6. The next day Christine was to run with the Post cross-country team at the regional meet. Rich Degnan, the Post coach,"and Post officials offered a car service and tickets on the last flight-to Boston for Christine and Toscano. When they arrived at the hotel, the entire team was waiting up for her.
Everybody knew about it at the regional meet. Degnan had to arrange for the flexibility of an alternate, just in case Christine could not go. Several times during the race, Christine felt she could not continue. But then she heard her friends and all those other people, those strangers from other colleges, calling her name. She thought about Jennifer. And she ran. She finished fourth in 22 minutes 58 seconds, breaking the Post record for the 6-kilometer distance by 15 seconds. And although the Post team didn t qualify for the nationals, Christine did.
59. The efforts Christine s Post team made for her include the following EXCEPT ____________.
A. offering car service and flight tickets to Boston

C. taking care of her food and uniforms
D. cheering for her during the race
60. We can learn from the passage that ____________.
A. Christine s two sisters were killed in the accident
B. Christine s athletic performance stood out in the race
C. Christine flew to Boston after her sister s funeral
D. Christine broke the Post record in national meet in Boston
61. What is the crucial factor contributing to Christine s success in the race?
A. Diligent practice. B. Excellent coaching.
C. Good relationships. D. Firm determination.
C
The most complex object known to humanity is the human brain — and not only is it complex, but it is one of the few natural phenomena that science has no consciousness of. To try to replicate (复制) something that is so poorly understood may therefore seem like pride. But you have to start somewhere, and International Business Machines (IBM) and the Ecole Polytechnique Federale de Lausanne (EPFL), in Switzerland, propose to start by replicating “in silico”, one of the brain s building blocks.
In a partnership announced, the two organizations said they would be working together to build a simulation (模拟) of a structure known as a neo-cortical（新大脑皮质的）column on a type of IBM supercomputer that is currently used to study the molecular functioning of genes. If that works, they plan to use more powerful computers to link such simulated columns together into something that mimics（模仿) a brain.
In a real brain, a neo-cortical column is a cylindrical（圆柱形的）element about a third of a millimeter in diameter and three millimeters long. It is these columns, arranged side by side like the cells of a honeycomb, which make up the famous “grey matter” that has become shorthand for human intelligence. The Blue Gene/L supercomputer that will be used for the simulation consists of enough independent processors for each to be programmed to mimic an individual nerve cell in a column.
The EPFL s contribution to the Blue Brain Project will be to create a digital description of how the columns behave. The database from its Brain Mind Institute will provide the raw material for the simulation. Biologists and computer scientists will then connect the artificial nerve cells up in a way that mimics nature. They will do so by assigning electrical properties（电能）to them, and telling them how to communicate with each other and how they should modify their connections with one another depending on their activity. 10,000 connections with others. And nerve cells come in great variety—relying, for example, on different chemical transmitters to carry messages across those connections. Eventually, however, a digital representation of an entire column Should occur.
Assuming that the growth of computing power continues to follow Moore s Law, the leader of IBM s side thinks it should be practical to mimic an entire human brain in silico this way in ten to fifteen years. Such an artificial brain would, of course, be a powerful research tool. It would allow neurological experiments that currently take days in a “web lab” to be conducted in seconds. The researchers hope that their simulated brain will reveal the secrets of how certain psychiatric and neurological, disorders develop. But that is probably not the real reason for doing it. The most interesting question, surely, is whether such an artificial brain will be intelligent, or conscious, or both.
