分析過(guò)量使用化石燃料例如煤和油，引起了很多嚴(yán)重的環(huán)境問(wèn)題，科學(xué)家正在盡力找新的不會(huì)污染環(huán)境的能源，太陽(yáng)能就是其中之一．下文介紹了太陽(yáng)能．科學(xué)家還在致力于更多的實(shí)惠的太陽(yáng)能系統(tǒng)．

解答 37-40 BADC
37．B．細(xì)節(jié)題，根據(jù)第二段Solar power is a kind of electricity which is produced by taking energy from the sun，using solar panels可知太陽(yáng)能是一種來(lái)自太陽(yáng)的能源，故選B．
38．A．詞意理解題，結(jié)合It helps to reduce waste and pollution，which is great for the environment可知對(duì)環(huán)境有好處，也就是減少垃圾和污染，故選A．
39．D．段意理解題，結(jié)合However，the power is not as widely used as expected．可知下文是在說(shuō)太陽(yáng)能廣泛使用的困難，故選D．
40．C．推理題，結(jié)合The power is clean and renewable．It helps to reduce waste and pollution，which is great for the environment．In the areas that are too far away to send electricity to or not easy to build electric power plants，solar power is especially necessary．It enables the people there to use lights，TVs，computers，washing machines，fridges and many other things．可知太陽(yáng)能是一種干凈的有用的能源，故選C．

點(diǎn)評(píng) 本文有一定的難度，文章稍長(zhǎng)，出現(xiàn)了一些生詞需要自己結(jié)合文章來(lái)理解，本文的問(wèn)題大部分是細(xì)節(jié)理解題，可以直接從文中找出，剩下的是主旨大意題只要理解文章意思也可輕松解答．

Amy Youn9：About Classroom Safer7

17．A Nepalese teenager had made a£23solar panel （太陽(yáng)能電池板） using human hair．
Milan Karki，who is 18 years old and lives in a village，used human hair to replace （代替）silicon，which is a common but expensive part of solar panels．By using hair as a replacement，Karki says that solar panels can be produced for around£23．
Karki got the idea from a Stephen Hawking book，which explained how to create energy from hair．The device （設(shè)備） that Karki has showed can produce 18w of energy--plenty to charge a mobile phone．
"Half a kilo of hair can be bought for only 16p in Nepal and last a few months；but a pack of batteries （電池） would cost 50p and last a few nights，"according to The Daily Mail．The solar panel is easy to service as the hair is easy to replace．Karki has now sent out several devices to other places near his home for testing．He said，"First I wanted to provide energy for my home，then my village．Now I am thinking for the whole world．"

2．What do you think of black cats？Are they unluckier than cats of other colors？Many people in Western countries think so．Scientists at the University of California，Berkeley （UC Berkeley），did a study on cat colours and people's understandings of cat personalities．
The study found that people do judge（判斷） cat personalities by color．Scientists did a survey on the Internet．There were 49statements（描述） matching five cat colorings with 10personalities．People think orange and bi-coloured （雙色的） cats are friendly，tri-coloured （三色的） cats are not generous，and white cats are calm，lazy and shy．As for black cats，people think they don't have special personalities．
But why do so many people dislike keeping black cats as pets？People think black cats have less special personalities，which might be because of their bad reputation（口碑）．They think black cats may bring bad luck，especially at Halloween．Movies and television shows also make people believe that．
Although people have these ideas，UC Berkeley scientists give another reason：people don't think black cats are pretty enough．After all，nothing can show black cats are unluckier than other cats．"You can't judge a cat by its colour，because it's the personality of the cat，not the colour，that will let you know if the cat is right for you，"Cathy Marden，a scientist said．
