A group of swimmers has described how a group of dolphins protected them from a group of white sharks （食人鲨）off the coast of New Zealand. The lifeguards were on a training swim when they came across a group of great white sharks before the dolphins raced in to help.

The swimmers were surrounded by the dolphins for forty minutes before they were able to make them safety back to the beach. It was an uncomfortable experience as they were circled by a group of white sharks, which came within a couple of meters of them. Lifeguard Rob Howes was in the water with a colleague and his teenage daughter. He said around half a dozen dolphins suddenly appeared and forced them to gather together. The mammals swam in tight circles to create a protective wall between the white sharks and the lifeguards as the great white sharks were under the surface.

The swimmers said the dolphins were extremely upset and repeatedly slapped (拍打) the water with their tails as if to try to prevent the white sharks from attacking them. It’s a day they’ll never forget, especially for one who was on her first day as a volunteer. They have no doubt that the dolphins acted on purpose to protect them. Researchers have said that they’re not surprised. A marine biologist insisted that dolphins, which are considered to be one of the most intelligent mammals, “like to help the helpless.”

Carrot juice, because of its many healthy benefits, is commonly called the "magic juice". It has been found that adding carrot juice to people’s diets greatly improves their health. And its delicious taste makes it popular with all members of the family as a beverage.

Carrot juice is one of the richest sources of vitamin A that can be used in the daily diet. Lack of vitamin A can cause dryness and damage to the skin, nails and hair. Drinking carrot juice to increase the vitamin A in the diet is said to be good for many parts of the body, including the bones and teeth.

Drinking carrot juice is thought to be extremely helpful to the liver (肝脏), because vitamin A helps to clean the liver and reduce fat in it. And it is suggested that drinking carrot juice should be done regularly, rather than just from time to time.

Drinking carrot juice is also thought to improve the eyesight because of the vitamin A in the juice. Lack of vitamin A can lead to night blindness, which can be very dangerous, especially when the person is driving a car. An easy way to find out if you are lacking in vitamin A is to walk from a bright room into a dark room. Your eyes may have some trouble in getting used to the change of light if you are lacking in vitamin A.

How can you make carrot juice? Wash some carrots well in cold water. Scrape (刮) them lightly, but do not peel them, as this will take away valuable vitamins and minerals that lie close to the skin.

UFO stands for "unidentified flying object"(不明飞行物). Many people reported having seen UFOs in the sky. A lot of countries tried to research into them and in 1952 they got the name of UFO.

There were several reports published in the 19th century which were related to UFOs. Denison Daily News in its report of 25th January, 1878 wrote that a farmer, Martin saw a flying object in the sky and it was just like a plate. This was the first time that the word plate had been related to the UFO.

First reports on UFOs came during the World War II. In 1947 the pilot Kenneth Arnold said while he was flying near the Mount Rainer he saw a very bright object in the sky. He told that it was like a plate, too. The information given by Kenneth got lots of attention from the media and people.

Several research organisations gave their reports on the UFOs. They showed direct or indirect physical evidence of UFOs, and sometimes UFOs’ appearance was found in the radar (雷达) screen. Many people try to take video tapes or photos of UFOs as proof. Most UFOs are in plate shape while many UFOs are like cigarettes or half balls.

Many films and TV shows are made about UFOs. There are two famous movies which are created on the topic of UFOs and aliens (外星人), War of the World and Star Wars. UFOs have created a new field in science which is known as Ufology (飞碟学).
