7 . With more people concerned about the environment, you can expect to see many more electric vehicles( EVs电动汽车) on the road in future.
Since they’re powered by electricity, EVs also apply full power as soon as the driver hits the accelerator (加速器).
Of course, there are also disadvantages. Most EVs can drive over 200 miles on one full charge.
A.There are many benefits of owning an EV. |
B.At that point, though, they need to be recharged. |
C.Many drivers also report that EVs feel more secure. |
D.This may help them speed up faster than gas-powered cars. |
E.As the name suggests, electric vehicles rely on electricity alone. |
F.Many people prefer EVs because they can reduce their stress. |
G.So what is it like to drive an electric vehicle instead of a gas-powered car? |
8 . Counting stars is pretty difficult in areas with lots of light, like major cities. A study says even in the clearest skies, you’re still seeing turbulence (涡流) in the atmosphere that makes stars twinkle. Want a truly perfect view of outer space? An international research team has found the spot, but you’ll need to wrap up warm. It’s in Antarctica!
According to the University of New South Wales, turbulence causes light coming from stars to bend as it reaches the Earth’s surface. That instability( 不稳定) in the air makes stars twinkle.
The location in Antarctica, however, has so little turbulence that it hardly interferes (干扰) with the light from stars, making the view extraordinarily clear. The Chinese-led research team built a system of telescopes on the top of a plateau(高原), named Dome A, which sits 4,000 feet above sea level.
“Dome A is the highest point in the central plateau of Antarctica, and the atmosphere is extremely stable here, much more so than anywhere else on Earth,” says UNSW Professor Michael Ashley. “The result is that the twinkling of the stars is greatly reduced, and the star images are much sharper and brighter. In fact, this special place even has advantages over the famous Hubble Space Telescope.”
“Satellites are a lot more expensive,” the astronomer explains. “But another advantage of making Earth-based observations is that you can always add the latest technology to your telescope on the ground. In space, everything is delayed (延迟). So you end up with technology in space lagging that on the ground by 10 years or more.”
One of the biggest advantages Dome A’s location has is that winter nights in Antarctica are very long. In fact, scientists will be able to track stars continuously since some nights in midwinter last for almost 24 hours.

9 . There have been so many improvements in detecting cancer from blood tests to virtual devices that can detect tumors(瘤) painlessly. Now, a new visual technology will allow doctors to detect skin cancers in just 10 seconds.
Researchers from Tel Aviv University (TAU) have come up with a new visual technology that can find out skin cancer without ever cutting into the patient’s body. Skin cancer detection has always been a long process of doing a traditional examination of harmful changes and then waiting for the results. But this new method is so fast that you can know the results instantly.
Early detection of melanomas (a kind of tumors) can save lives according to the researchers. If a melanoma is detected early, and removed right away, the chances for a full recovery are very good. This new technology is built upon the knowledge that harmful changes give off different colors when placed under special light that shows if they are fatal (致命的)and what type of cancer is present. Instead of removing the harmful changes for examination, the research team pioneered a way to check them on the body.
The research was published in the journal Medical Physics, saying the optical technology was tested on 90 patients and it accurately identified the 5 patients with melanoma and 10 with other skin cancers. In addition, 75 other patients that had harmful changes were correctly identified as cancer-free.
The next stage involves testing the technology on many more patients in the hope that it can be used to create an easy-to-use machine that will be able to find out harmful changes on a screen. The visual technology will have the potential to cause an immense change in the field of detecting and treating skin cancer, which increases survivability and the quality of life.
