From July to October every year, about a quarter of the world's blue whales feed in the Pacific Ocean off the coast of California. But the whales currently face a major threat in their favorite feeding area. Ships carrying cargo (货物）sail in the same area at the same time. All too often, the whales' paths and the ships' travel lines overlap (重叠), and a ship will hit a whale.

    According to a new study, these ship strikes have become a serious threat to the overall population of the world's blue whales. Only about 10,000 of the creatures still exist worldwide. Blue whales are the largest known animals ever to live on Earth. Even so, if hit by a container ship, a blue whale will likely die from its injuries.

    In 2007 alone, large ships killed five blue whales in the waters off San Francisco and Los Angeles, California. The National Oceanic and Atmospheric Administration (NOAA) says that because there are so few whales already, losing three to five from the California whale population every year is a significant loss. “The estimated population of blue whales in this part of the Pacific is 2,500”, says Sean Hastings, a NOAA analyst. “So every whale counts toward this species moving off the endangered-species list.”

    Now, marine scientists must figure out how to protect the whales from the giant container ships. One very simple program is already under way in the Santa Barbara Channel, a waterway that separates mainland California from the nearby Channel Islands.

    The Channel Islands National Marine Sanctuary has asked large container ships passing through the area to voluntarily slow down. Sailing slower will allow the ships‟ crew (船员）more time to change course before hitting a whale.

    Several of the world's largest shipping lines are set to participate in the new program. For every ship that passes through the Santa Barbara Channel at or below the reduced speed of 12 knots (海里/小时）, the company that owns the ship will be paid $2,500.

    Mobile Safety App Powered by LiveSafe

    The Mobile Safety App powered by LiveSafe, manage by the USC Department of Public Safety and the USC Department of Emergency Planning, is a free downloadable app that that mobile users can use to initiate contact with emergency responders around the campus. Features include: immediate “push button” calls to DPS, easy reporting for suspicious activity or crimes in progress, and location services to notify friends of your route through campus.

    Blue Light Phone Locations

    The University Park has multiple blue light phones that are strategically placed throughout campus. Take note of where the closest ones are on your route. They come in handy in case you lose your phone or in an emergency. These phones are directly connected to USC's Department of Public Safety's 24-hour communications center. Besides emergency needs, it can also be used to report suspicious activity, request for an escort (护送) if you feel unsafe and to report a crime.

    Trojans Alert

    Trojans Alert is an emergency notification system that allows university officials to contact you during an emergency by sending messages via text message or email. When an emergency occurs, authorized USC senders will instantly notify you with real-time updates, instructions on where to go, what to do (or what not to do), whom to contact and other important information. All members of the USC community, as well as parents and regular visitors to campus, are strongly encouraged to sign up for Trojans Alert.

    What's the meaning of "dark horse"? It's someone who wins when no one expects it.Han Xiaopeng took China's first gold on snow. He became an Olympic "dark horse" by winning the gold medal in men's freestyle aerial skiing(自由式滑雪空中技巧) at Turin in Italy. He made two almost perfect jumps for the highest score. Han had never won a world gold medal before, let alone(更不用说) in the Olympics!

    "I never thought this would happen," said the 23-year-old. "I feel like I'm in a dream." It's China's second gold medal at the Turin Olympics. But more important, Han's gold was the country's first ever in a snow sport. In 2002, China's Yang Yang won the gold for speed skating at the winter Olympics in Salt Lake City, US.

    That Han's win was unexpected doesn't mean that he didn't work hard.

    Han grew up in Jiangsu Province. Before he started his training on snow, he used to be an acrobat(杂技演员) at a circus. In 1995, a coach found his talent(才能). The coach, Yang Er'qi, said Han had the agility(灵活性) and courage to be a ski jumper. When Yang first took the 12-year-old to northern China, the boy couldn't swim, skate or ski. But he wasn't afraid of the high platform(跳台) and kept on training.

    Han almost left the sport after hurting his knee months before the Salt Lake Games. In that Olympics he only got 24th. "I was hopeless at that time, but my family and the coach stood firmly(坚强地) behind me, helping me through," he recalled.

    Han Xiaopeng worked so hard that he won the gold medal in the Olympics at last. Because of his success, more and more people in China are becoming interested in skiing. We are proud of him and we hope he will have another big success in the next winter Olympics.

Fishy Weather Conditions

    Laj amanu, Australia, is a dry little town, sitting right on the edge of the Tanami desert. Can you imagines how surprised were people when live fish rained down on them from a dark gray cloudy. It happens that there are similar cases in England and Honduras.

    How do clouds make fishy. The simple answer is that they don't. There is a particular weather phenomenon(现象)called a waterspout. A waterspout is just like a tornado, only it forms above oceans, lakes, or rivers. Like a tornado, a waterspout moves in a circle at high speeds. When it moves above the water, it tends to carry the fish with it, as well as frogs or other small plants or animals.

    Scientists couldn't work it out at first. To make matters stranger still, the fish in Honduras were very much alive when they rained down to the ground, but they were all blind. In England and Australia, it rained fish and snakes, and none were blind. It was difficult to puzzle out, but the blind fish gave them a place to start.

    Scientists knew that some fish that lived in deep, underground caves with no light sources often lost their eyesight. So when blind fish rained down on Honduras, scientists began to connect some dots. Clearly, these particular fish were pulled from an underground water source by force.

    It has rained fish on every continent, and each time, people have tried in various ways to explain this strange phenomenon. Historically, villagers thought the “fishes from the heavens” might be answers to prayers for food.  Others suggested that floods overran river banks and oceans, leaving the fish on the city streets. No scientist had actually seen the rain as it occurred, only the fish left on the ground. But in 1990, a National Geographic team happened to be in Honduras when the Rain of Fishes began. They recorded what was happening and made history by finally proving that the fish really did fall from the sky.

    This huge breakthrough wasn't just a spot of good luck. It changed thousands of years of myths and legends into true stories and provided scientific explanations for how fish came to live in deep caves. It explained ancient cave paintings and shed new light on how species have spread over time. It turned out to be a lot more than just a little fishy weather.

    We are currently on a camp site near Calais, on our way to the UK, and it is pouring with rain. As if gods want to prepare us for the UK at all costs. As if we don't know what rain is… Our ferry to the green isles will leave tomorrow at 10: 30 and despite the rain, I am really looking forward to it.

    It has taken us a while to get here, as we already left EI Chorro on 4 April. After rushing through Spain in two days, however, we came to an inevitable slow-down when we entered France. Inevitable, as France has simply too much to offer for us, so as soon as we crossed the Pyrenees, our driving sequence became something like driving a few kilometres, visiting a castle, driving a few kilometres, taking pictures of a nice church, driving a few kilometres, having a quick peek at a flea market, driving a few kilometres, visiting a museum etc. When we entered Brittany the real sightseeing started, in Vannes, in Lorient, in Brest and then on to Normandy: Le Mont St Michel, Bayeux and finally, finally the D-Day beaches. I always wanted to visit these, for obvious reasons I would say, but my father, realistic as he was, calculated the chances that it would rain a considerable amount of days of a three-week holiday and always decided against it. But a few days ago I finally stepped onto Gold Beach (where the Brits landed) and I was greeted by the Norman sun. A beautiful day.
