【题目】Music lessons may improve memory and learning ability in your children by promoting different patterns of brain development, a study shows．
After a year of musical training, children aged between 4 and 6 performed better at a standard memory test than did children who were not taught music．The findings suggest that music could be useful for building the learning capacity of your minds．
Earlier studies have shown that older children given music lessons become better at IQ tests than those who are musically untrained, but this is the first to show such a benefit in children so young．
Professor Laurek Trainor, of McMaster University in Hamilton, Ontario, also found clear differences in the ways in which children's brains responded to sound after a year of musical training．'This is the first study to show that brain responses in young, musically trained and untrained children change differently over the course of a year," she said．"These changes are likely to be related to the cognitive（ 认知的 ）benefit that is seen with musical training．"
Professor Trainer's team looked at 12 children, 6 of whom had just started extra-curricular （课程外） music lessons and 6 of whom were not being taught any music except that included as a standard part of their school curriculum （课程标准） ．
During the year all 12 children had their brains examined four times using magneto-encephalography （MEG）, and each child was played two types of sound —white noise and a violin tone．The MEG measurements showed that all children responded more to violin sounds than to white noise, reflecting a preferable for meaningful tones, and their response times fell over the course of the year as their brains matured．
【1】This passage is mainly about ____．
A．why music lessons are good for the memory
B．the benefit from extra-curricular training for younger children
C．a study on twelve young children's brains
D．new technology to examine children's brains
【2】It can be concluded from the text that ____．
A．the study is the first one on the effect of musical training on children's brains
B．scientists got no valuable results from the earlier studies on the topic
C．children musically trained remember things better than those untrained
D．older children get more benefit from musical training than younger ones
【3】What do we know about the twelve children tested in the study?
A．None of them had been musically trained before．
B．Only 6 of them had a knowledge of music before．
C．Not all of them had been taught some music in school．
D．All of them were required to learn some music in school．
【4】We know from the MEG measurements that ____．
A．the older a child is, the more quickly he/she responds to sounds
B．human brains prefer musical sounds to white noise
C．children of different ages respond to sounds at the same speed
D．all the twelve children like to learn to play the violin very much

【题目】E
Small endangered animals are often hard to find in their natural habitats, making it difficult for scientists to monitor them and develop conservation plans. But new technologies can help. Australian researchers have equipped flying drones with infrared cameras so they can spot koalas hiding high in trees.
Koalas spend most of their lives in eucalyptus trees, whose leaves are their favorite food. Since the leaves are low on calories and nutritional content, koalas are not very active - they sleep up to 20 hours a day. Curled-up in high branches, they are not easy to spot from the ground, and they have few natural predators. The greatest threat to this iconic symbol of Australia is logging.
“Every single tree in Australia right now, needs to be protected and unless that happens I can promise you the koala is going to go to extinction,” said Deborah Tabart, Australian Koala Foundation.
Scientists studying koalas say one of the keys for saving the animals is to know where they live and how many of them are left.
Using drones fitted with infrared cameras to conduct a census was an untested concept. Queensland Institute of Technology technician, Gavin Broadbent, said they were skeptical at first. “But when we saw the images come through, we saw the koalas were very distinct compared to the trees and the environment. So we thought, yes this is absolutely a proof of concept that could work,” he said.
The images beamed back to a computer clearly show the animal’s position, even from a distance far enough away not to disturb its sleep.
“We have tested at 20 meters and 80 meters. At 20 meters we get really good resolution,” stated Felipe Gonzalez, project leader.
The remotely controlled camera pivots and swivels, so scientists can scan the trees from all angles, picking out koalas even in the most dense areas, not visible to researchers on foot.
“So this will drastically reduce the manpower," said Amber Gillett, a veterinarian with the Australia Zoo. "Will greatly increase the area that can be covered to survey koalas and in areas where people may not be able to walk through because of dense undergrowth.”
Scientists say it is now clear that drones with infrared cameras can be used for spotting, and perhaps saving, other animals in the wild.
【1】What is an important factor in protecting the animals according to the passage?
A. To know how they live and how many of them are left.
B. To protect the place they live in.
C. To learn their positions and their number.
D.To stop killing them by educating people.
【2】What is the meaning of the underlined word “logging”?
A. cutting B. hunting C. killing D. destroying
【3】Which is not the advantage of drones with infrared cameras?
A.They can take photos of animals from a distance far away.
B.They can help reduce the manpower.
C. They can scan the trees from all angles.
D. They can send the images back to a computer.
【4】What is the main idea of the passage?
A. Koalas in Australia have been found by drones with infrared cameras.
B. New technologies can be used in drones to set up environment suitable for endangered animals.
C. Drones with infrared cameras can be used to save small endangered animals.
D. The functions of the remotely controlled camera are proved.
