第二部分 阅读理解（共25小题；每小题2分，满分50分）
阅读下列短文，从每题所给的四个选项(A、B、C和D)中选出最佳选项，并在答题卡上将该项涂黑。
A
Kenji Croman has broken his bones, his shoulder and elbow, and nearly drowned several times. He's also had three close encounters with sharks over the years. A 10-foot wave landed directly on top of him five years ago, bending his body to the point that he actually kicked himself in the head. "I literally heard every bone in my body crack, " he said.
Croman has been photographing ocean waves since 2008, sometimes risking his life to get that perfect shot at the surf break. Despite the risks and certain injuries that come with wave photography, the Hawaii resident, body surfer and former competitive swimmer wouldn't do anything else. The 36-year-old photographer loves the thrill of meeting breaking waves head on, shooting waves as his interest and shooting surfers to pay the bills.
The process of photographing waves requires more than just swimming out to where the surf breaks and waiting, he says. The night before a photo shoot Croman checks Surfline. com, a website and the coastal camera network that provides live and predicted ocean weather information, to see what the winds, waves and tide will be like at certain times. Croman has both a primary camera and a backup for emergencies. He goes without a wetsuit and uses heavy duty underwater housing to protect his camera. There is no great way for him to protect himself. He admits there are probably protective clothes he should be wearing, but there is little he could have done to decrease the impact of the lo-foot wave that crashed on top of him.
The hardest part of Croman's job is staying calm in the face of breaking waves when his initial reaction is to panic and swim away. At most, Croman will take two to three shots of a single wave. "I've shot waves for so many years now that I see the wave in slow movement, " he said.

A San Diego boy Kristoffer Von Hassel has the gaming world' s attention after he exposed a security weakness that let him log into his dad's Xbox Live account, without permission.
Kristoffer's father, Robert, noticed soon after Christmas that his son was logging into his account and playing games that weren’t appropriate for his age. When he asked how, Kristoffer showed him a hack that seems simple but is fairly impressive considering a 5-year- old found it.
Kristoffer would go to his dad's account and type in an incorrect password. That would take him to a password verifications (确认) screen, where he would simply tap the space bar repeatedly and then press "enter. "
"How awesome is that?" asked Davies, who works in online security himself. "just being 5 years old and being able to find a vulnerability I ty and getting attached to that I thought that was pretty cool." He told KGTV that Kristoffer has figured out three or four other "hacks", including getting past the lock on a smartphone by holding down the "home" key for long enough.
Davies reported the vulnerability to Microsoft. And Microsoft acted, issuing a fix for it. "We' re always listening to our customers and thank them for bringing issues to our attention," the company said in a written statement. "We take security seriously at Xbox and fixed the issue as soon as we learned about it. "
The company has even included Kristoffer's name on a list of security researchers who have helped make online Microsoft products safer. For his discovery, or more accurately, for reporting it with his father's help, Kristoffer will receive four games. $50 and a year's subseription to Xbox Live from Microsoft.
