Several recent studies have found that being randomly (随机地) assigned to a roommate of another race can lead to increased tolerance but also to a greater likelihood (可能性)of conflict.
Recent reports found that lodging with a student of a different race may decrease prejudice and force students to engage in more ethnically diverse friendships.
An Ohio State University study also found that black students living with a white roommate saw higher academic success throughout their college careers. Researchers believe this may be caused by social pressure.
In a New York Times article, Sam Boakye – the only black student on his freshman year floor -said that "if you're surrounded by whites, you have something to prove."
Researchers also observed problems resulting from pairing interracial students in residences.
According to two recent studies, randomly assigned roommates of different races are more likely to experience conflicts so strained that one roommate will move out.
An Indiana University study found that interracial roommates were three times as likely as two white roommates to no longer live together by the end of the semester.
Grace Kao, a professor at Penn said she was not surprised by the findings. "This may be the first time that some of these students have interacted, and lived, with someone of a different race," she said.
At Penn, students are not asked to indicate race when applying for housing.
"One of the great things about freshman housing is that, with some exceptions, the process throws you together randomly," said Undergraduate Assembly chairman Alec Webley. "This is the definition of integration."
"I've experienced roommate conflicts between interracial students that have both broken down stereotypes(模式化形象) and strengthened stereotypes," said one Penn resident advisor (RA). The RA of two years added that while some conflicts "provided more multicultural acceptance and melding (融合)," there were also "jarring cultural resistance."
The RA said that these conflicts have also occurred among roommates of the same race.
Kao said she cautions against forming any generalizations based on any one of the studies, noting that more background characteristics of the students need to be studied and explained.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Hospital emergency rooms treat injured fingers all the time．Without treatment, a bad cut can lead to permanent damage．But how should a person know when a bleeding cut is serious enough to require medical attention?
Here are some tips from Dr．Martin Brown, chairman of the department of emergency at Inova Alexandria Hospital in Virginia．
1．Laceration （裂口）
The medical term for a cut or tear in the skin is a laceration．【小题1】 A long cut on a finger can likely be treated without a visit to a doctor if the wound is not very deep．However, if you have a short but deep laceration, you will need professional attention,
2．Fingertips cut off
Some injuries, like a fingertip that gets cut off, might even need surgery （外科手术） to repair．【小题2】 More often, cutting down the bone is what is done because reattaching a fingertip is often not successful．
3．Bleeding
【小题3】 Small cuts usually produce what is known as venous （静脉的） bleeding．This means the blood flows steadily from the injury．The bleeding will often stop when pressure is put on the wound．In most cases holding direct pressure with a clean cloth for four to five minutes would do. But if a cut appears to be pumping blood out with some force, this may be a sign of arterial （动脉的） bleeding．__【小题4】_
Finally, always keep this in mind: even a cut that does not require medical attention must be kept clean to prevent infection．Small cuts should be cleaned gently with clean water．_【小题5】 Then cover it with a clean, dry bandage．
| A．How a wound bleeds can be a sign of how serious it is． |
| B．That requires a specialist to either cut down the bone or reattach the fingertip． |
| C．This kind of injury should be treated by a medical professional as soon as possible |
| D．The first signs of this disease include difficulty opening the mouth． |
F．With a cut finger, holding the hand above the heart can reduce the loss of blood．
G The length is usually not as important as the depth．
__【小题1】___ Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.
The ridge （隆起） structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original pattern.【小题2】 Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.
Finger-prints can be made very easily with printer's ink. They can be recorded easily.
___【小题3】___ Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. ___【小题4】___ .
When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. ___【小题5】___ . Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.
| A．Special techniques are used to "develop" them. |
| B．A fingerprint is an impression of the friction ridges of all part of the finger. |
| C．It is only when the inner skin is injured that the arrangement will be destroyed. |
| D．With special methods, identification can be achieved successfully within a short time. |
F. His finger-prints can prove who he is even if his appearance has been changed by age or accident.
G. Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable.
