2 . Jane Goodall is a famous animal behaviorist and has spent many years observing the behavior of chimps in their native habitat. Jane Goodall was born on April 3rd, 1934 in London, England. Her childhood dream was to spend time with animals in the wild. In particular, she was drawn to Africa and the dream of seeing wild animals in their native habitat. It was an unusual dream for a girl at the time, but her parents said to her, “We know it’s different, but we are at your back.”

In 1956, Jane jumped at the opportunity to travel to a friend’s farm in Kenya. It was there that Jane met the famous anthropologist, Dr. Louis S.B. Leakey. Leakey was impressed with Jane’s passion and knowledge of Africa and wildlife.

In 1960, Leakey and Jane began an important study of wild chimps by Lake Tanganyika. The chimps showed some fascinating habits to the group. These included meat eating, which is completely different from the previous opinion about chimps. Also, Jane saw chimps making tools to catch insects. This was an important discovery because, at the time, it was assumed only humans made tools.

The study of chimps in their native habitat was a significant event, leading to many new observations. Jane’s first article My life among wild chimpanzees was published in National Geographic in 1963. Some aspects of the study were challenged. For example, some feared her decision to feed the animals might have distorted their behavior and made them more aggressive (好斗的).

In 1977, Jane set up the Jane Goodall Institute which promotes plans to look after chimps and their environment. The institute has many networks and programs all over the world.

December 5th is the International Volunteer Day. It    1     (establish) by the UN in 1985. It has two aims: first, to thank volunteers around the world for    2     (give) their time to help others; second, to encourage other people to do voluntary work. Without volunteers, many people around the world would be much    3     (bad) off. In fact, the whole world would be    4     darker place. Volunteers help other people and help animals, the countryside, the environment and many more things    5     are important to us. The UN urges governments around the world    6     (take) measures to heighten awareness of the important    7     (contribute) of volunteering.

There are thousands of volunteer organizations around the world. A search    8     the Internet will give you a volunteer group on anything or anyone you want to help. You don’t need to join a worldwide group to be a volunteer. Most voluntary work that takes place around the globe is done by    9     (individual) helping their neighbors. We have probably all gone out of our way to help someone less fortunate. Most    10     (important), volunteering makes you feel like a useful person. So, on this International Volunteer Day, think about how you can help, and offer your services.

7 . Saving money, even if only a little, can have a significant effect if done consistently every month.     1     Actually, everyone can spend money wisely by following the tips below.

Prepare a budget

This way, you don’t spend too much or don’t always follow your desires. However, it doesn’t mean you sacrifice your desire to have fun. You can make a budget for each need including the need to have fun.     2     If you have set a certain amount for self-indulgence (享乐),the amount should not increase until the end of the month.

Have a clear goal

Saving money has many purposes. What is your motivation for saving money? Do you want to buy a house 5 years from now? Do you want to have enough capital to start your own business? If you have a clear goal, you will be motivated to save money.     3    

Compare prices

When you want to buy something, such as food, clothing, medical supplies or anything,you can compare prices first.     4     But, if by comparing prices and then buying from a seller who offers a lower price, you can save more money, why not?

Learn various DIY techniques

What can you do yourself? There’s a lot. By learning various DIY techniques, you can save money for other needs. For example, if you find a hole in your T-shirt, you can sew it yourself instead of going to a tailor.     5    

8 . No one can resist the temptation (诱惑) of snacks. But at the same time, you may be underestimating how many calories a snack contains. What would happen if you had a bag of crisps (炸薯片) a day? Eating an extra packet of crisps a day could lead to a weight gain of 6. 35 kg after a year, The Times reported.

People underestimate the number of calories in their snacks, with experts warning that eating a bag of crisps every day could lead to a stone of weight gain in a year. A survey of around 2 ,000 adults found that about three quarters underestimated the impact of what a small reduction could have. One in ten believed that cutting 200 calories a day would not affect weight. At the same time, many people didn’t seem to know exactly how many calories were in their snacks. When it came to snacks, people struggled, with 95 percent guessing that half a sharing bag of tortilla chips had 214 calories on average, almost half the true figure of 447.

Can’t we resist buying snacks? The food environment is to blame. Even though we all know snacking is bad for our health, we can’t help but fill our shopping carts with snacks.Don’t always blame yourself for poor self- control, and supermarket shelves also have to carry this “pot” half.

Hugo Harper, head of Nesta’s health team, said the pressure to resist high-calorie snacks should not be put on consumers and that our food environment needed. to be changed, He said,“Our environment has a real impact on what we eat, from advertisements and supermarket promotions to what ‘s available in our local corner shops.

Hugo added,“If we had fewer cues to snacks, or were pushed to buy fewer high calorie snacks, we should be able to see real change.”New rules coming into force next month will restrict promotions on foods high in fat, sugar and salt in big shops.

9 . A do-it yourself device could help to unlock the next generation of solar energy, including advanced technology for space missions. Dr Jamie Laird, a research fellow at the ARC Centre of Excellence in Exciton Science, has invented a new device for testing the shortcomings of perovskite (钙钛矿) solar cells, the first of its kind anywhere in the world.

Perovskite solar cells that can match silicon (硅) for efficiency are cheaper to manufacture and more flexible, but they haven’t become commercially available yet, because they are still too unstable when exposed to heat, light and oxygen. That’s where Jamie’s device comes in. With a combination of a microscope and a special laser (激光器)，it produces pictures and maps of the drawbacks within solar cells and tells scientists where the cells are losing power or efficiency over time and use. It also provides data to indicate why.

The innovative technique starting life as a personal project for Jamie was originally intended to analyse minerals. When he joined Exciton Science, Jamie realized his device would be a perfect tool to help his colleagues and other leading solar cell researchers around the world to better understand the frustrating issues that have kept perovskite from meeting their exciting promise.

“We use a laser beam and we focus on a spot and scan across the device to measure the quality of the solar cell. This new method allows us to do imaging analysis of the whole or complete solar cells and look at how they perform, how they change with time and aging, and how good a solar cell it is,” Jamie said.

“You can’t have a solar cell that decomposes quickly when it’s meant to last 20 years in the field,” Jamie added.“This is a missing link in the whole of techniques we have to throw at that problem.”
