At just 18 years old, Canberra student Lochie Ferrier has already conducted research in a frontier field — aerospace engineering. Aerospace engineering is the primary of engineering concerned with the science and technology of aircraft and spacecraft.
In 2014, he was one of 80 high school students worldwide who a six-week science and engineering program at MIT. During the program, he was by the institute’s scientists, and developed a method to identify inactive satellites. This method, called OASIS, is designed a way to help manage space debris(碎片), which operating satellites.
“One solution to this problem is a robot that can gather pieces of space debris and store them in orbit,” he says. “These pieces could be to new satellites later, thus the costs and launch weights of new satellites.” However, satellite identification technology would be needed for this solution, and that’s what Lochie is working on. “I hope this method would be put into practice in the near future, in the next 10 years,” he says.
Lochie has made the of the Young Innovators category of the Australian Innovation Challenge Awards with his OASIS. This category is open to students aged 21 years or and carries a $ 5,000 prize. If he won, he would use the money to help fund research into OASIS. “My plan for using the money would be to try to use materials which could stand up to the environment of space,” he says.
He is also considering how to the technology to organizations such as NASA and satellite manufacturers.
Lochie’s in aerospace engineering was aroused by the big dish antenna(碟形天線)at NASA’s tracking station near Canberra,which he visited in his early teens. He said his software design and development teacher at Canberra Grammar School him, too. “He taught me valuable project management and skills which I applied to OASIS.”
Lochie has been attending Canberra Grammar School and will soon exams for admission to universities. He his time between schoolwork, his personal projects such as OASIS and the development of apps, rock climbing, and playing classical violin. The teenager is well on his way to realizing his sky-high ambition.

The World Wildlife Fund (WWF) says more than half of the world’s wildlife population has been lost, which the conservation group says has placed the health of the planet at risk.
The WWF recently released its 10th Flagship Living Planet Report. The group warns the condition of the world's animals is worse than its earlier reports showed, indicating worldwide action is needed.
The WWF is worried about the loss of and damage to Earth’s environment. The report provides information about more than 10,000 animal populations from 1970 to 2010. These populations are called “vertebrate species,” or animals with backbones — like fish, birds, mammals, amphibians and reptiles. The report shows these populations have dropped by 52 percent in just 40 years. It warns freshwater species have fallen by 76 percent, which is almost twice the loss of land and ocean species. Most of these losses are in the tropics, with the biggest drop in Latin America.
Marco Lambertini, the WWF’s International Director-General said, “This is about losing natural habitats. This is about converting forests, grasslands, and wetlands into agriculture mainly, and it is about unsustainable use of wildlife. Illegal hunting has been actually increasing over the last 10 years, which definitely a driving force for extinction, particularly of large species.”
The report also notes what it calls the world’s “Ecological Footprint”, that is, the effect of human activities on the planet. Mr. Lambertini says there has been an increase in carbon dioxide gases and the pouring of nitrogen into oceans and rivers from fertilizers used in agriculture, which certainly cannot continue.
“We are consuming on average every year about the equivalent of about 1.5, one and a half times the resources available to the planet. That means we are cutting trees more quickly than they can be restored. We are fishing the oceans more quickly than fishing stocks can reproduce, and we are emitting in the atmosphere more CO2 than the natural systems can actually absorb, which is clearly not sustainable.”
Mr. Lambertini warns climate change affects almost everyone on the planet and that whole species may disappear if the world does not reduce the effects of humans on the climate.
1.According to the passage, what kind of species faces the biggest drop in population?
A. Land and ocean species.
B. Animals with backbones.
C. Freshwater species in Latin America.
D. Freshwater species in the tropics.
2.All the following can contribute to the loss of world’s wildlife population EXCEPT ________.
A. turning wildlife habitats into agriculture land.
B. making sustainable use of wildlife.
C. hunting illegally.
D. emitting CO2 gases and pouring nitrogen.
3.Which does the underlined word “converting” in paragraph 4 mean?
A. Conserving. B. Conveying.
C. Exchanging. D. Transforming.
4.It can be inferred from the passage that _______.
A. Marco is much concerned about human’s current behaviors towards wildlife.
B. what the planet provides now can satisfy human’s sustainable development.
C. more than half of the world’s wildlife population has been lost.
D. if humans reduce the effects on the climate, the whole species will not disappear.

Why do young adult children become independent so much later than they did in 1970,when the average age of independent living was ? Why have reduced class sizes and increased per-pupil expenditures (花銷(xiāo))not 36 higher academic achievement levels? Why is the mental health of today’s kids so poor when with that of children in the 1960s and before? Why do today’s become defensive when told by teachers that their children have misbehaved in school?
The answer in two words: parental . Those two words best summarize the between “old” child raising and new, post-1960s parenting. Then, the overall philosophy was that parents were not to be involved with their kids. They were available crisis, but they stood a (an) distance from their kids and allowed them to experience the benefits of the trial-and-error process. It was the child’s , back then, to keep his or her parents from getting involved. That was children learned to be responsible and determined.
Today’s parents help their kids with almost everything. These are parents who are when it comes to an understanding of their purpose in their kids’ lives. Their involvement leads them to personalize everything that happens to their kids; , the defensiveness. But given that schools and mental health professionals have been pushing parent involvement for nearly four decades, the confusion and defensiveness are .
University researchers analyzed three decades of data relating to parent participation in children’s academics. Their conclusions what I’ve been saying since the 1980s: parental help with homework a child’s academic achievement and is not reflected on standardized tests.
Parents who manage a child’s social life interfere with the of good social skills. Parents who manage a child’s after-school activities grow kids who don’t know how to their own free time. Parents who get involved in their kids, with peers grow kids who don’t know how to avoid much less trouble.
These kids have anxieties and fears of all sorts and don’t want to leave their . And their parents, when the time comes, don’t know how to being parents. You can imagine what will become of their fu ture.
