2.Many teachers believe that hands-on experiences is the (61)best (good) way to learn.A group of students in the United States are putting that belief to the test.They (62)successfully(success) designed and built a robot for discovering unexploded mines(63)at the bottom of the sea.Students made the robot (64)to answer  (answer) a challenge from the U.S.Department of Defense.
The students recently tested the underwater vehicle (65)called (call) Perseus II in a 95-meter-long tank of water at the Stevens Institute of Technology.
The robot costs about 15,000to build.The students use a video game controller to direct its(66) movements (move) in the tank.What's more,devices know as Japters (67)enable (able) the robot to go up,down and toward its target in the water.Video cameras on the robot send images back to a computer through a 13-meter-long cable.Perseus II also has (68)aset of lasers(激光),which are used to measure the size of an object.
The robot is the creation of five undergraduate students.For over six months,they worked up(69)to20hours a week to design and build Perseus II.
DeLome supervised the project from the(70)beginning(begin) to the end.He says the specialized requirements of robot were demanding.

A healthy amount of sunshine may be the secret to staying young. British scientists have discovered.

Vitamin D is produced naturally by the skin in response to (对…的反应) sunlight and may help to slow the ageing process and protect against heart disease, according to the study.

Researchers from King's College London studied 2,160 women aged between 18 and 79, looking at their telomeres-a biological marker of ageing found in DNA. As people get older, their telomeres get shorter and they become more susceptible (易受伤害的) to certain illnesses.

But the study found women with high levels of vitamin D had comparatively longer telomeres-a sign of being biologically younger and healthier.

The study suggests vitamin D may help to slow down the ageing process of DNA, and therefore the ageing process as a whole.

Lead researcher Dr Brent Richards said, "These results are exciting because they show for the first time that people who have higher levels of vitamin D may age more slowly than people with lower levels of vitamin D." This could help to explain how vitamin D has a protective effect on many ageing related diseases, such as heart disease and cancer."

Professor Tim Spector, a co-author of the report, added, " Although it might sound absurd(荒唐的), it's possible that the same sunshine which may increase our risk of skin cancer may also have a healthy effect on the general ageing process.

Vitamin D made by the action of sunlight on the skin accounts for 90 percent of the body's supply, but lower levels can also be got through food such as fish, eggs and breakfast cereals(粥).

Other studies have suggested the vitamin plays a key role in protecting against cancer and heart disease.
