Diligence is a must for us to reach our goals. I never realized it until I tried every efforts to win the English speech competition last year.

It was quite a big challenge for me because I was not that confident about your oral English and I was shy to speak in public. To give a better performance, I made fully use of my spare time to prepare for it. I recorded my lines and ask my foreign teacher to correct my pronunciation. Then I kept practise day and night. Besides, I seized every chance to speak in the front of my family or friends. The more I practiced, the much confident I became. In the end, I won the competition but got a prize.

It was such great that all my efforts paid off. I was so proud myself.

6 . AQUILA Children’s Magazine is the most intelligent read for curious kids. Full of enthusiastic articles and challenging puzzles, every issue covers science, history and general knowledge. AQUILA is a quality production, beautifully illustrated with contemporary artwork throughout.

 Intelligent reading for 8-12-year-olds

 Cool science and challenging projects

 Inspires self-motivated learning

 Exciting new topics every issue

AQUILA is created and owned by an independent UK company. It has 28 pages, printed on high-quality paper and there are no advertisements or posters. Instead it is full of well-written articles, thought-provoking (令人深思的) ideas and great contemporary artwork. Each monthly issue is centred around a new topic.

AQUILA works as a superb learning extension to current primary (or KS2 and KS3) curriculum (课程), but it is much more than that! Entertaining and always surprising, AQUILA is recommended because it widens children’s interest and understanding, rather than encouraging them to concentrate only on their favourite subjects. It gives children a well-rounded understanding of the world, in all its complexity.

The concepts in AQUILA can be challenging, requiring good comprehension and reading skills. Eight years is usually a good age to start. Some gentle interest from an adult is often helpful at the start.

In 2021 AQUILA will have been in publication for 29 years, but it has never appeared in newsstands or shops. We are subscription only.

7 . A new study recently found that elephants in central African forests can encourage the growth of slow-growing trees and increase the ability of the forest to store carbon.

“As a tree, there’s a trade-off you can’t have it all,” explained Fabio Berzaghi, who led the study. “You either invest in growing fast, or in building a lot of structure with carbon to be more resistant.” Elephants prefer to eat fast-growing trees in more open spaces. As they feed and walk, they cause damage to these species, knocking over trees or breaking off branches, which results in an ecosystem that favors large, slow-growing hardwood trees. “As the elephants thin the forest, they increase the number of slow-growing trees and the forest is capable of storing more carbon, ” said Stephen Blake, one of the paper’s authors.

Scientists collected field measurements in the Congo Basin and used a computer model to predict how elephants would affect forest structure, and carbon storage potential in the long term. The data confirmed that when elephants are present, the forest contains larger trees and higher abundances of species with high wood density. Conversely (相反地)，should forest elephants go extinct, leaving those slow-growing trees struggling to compete with fast-growing species, it would result in a 7 percent loss of above-ground biomass (生物总量). As a result, central African forests could lose up to three billion tons of carbon, potentially accelerating climate change.

The sad reality is that humans are doing their best to rid the planet of elephants. “This study comes at a time when forest elephants are threatened as never before,” said Iain Douglas Hamilton, founder of Save the Elephants. “It is shocking that just as we are beginning to understand how elephants might have a key role in Africa in storing carbon, they are under real threat of extinction.” One limitation of the study, Mr. Berzaghi said, is that we do not know how much carbon has already been lost because of the elephants’ decline. But it does seem certain, he added, that putting a stop to illegal hunting and restoring forest elephant populations would bring climate benefits.

1. What can we infer about slow-growing trees in Paragraph 2?

A．They are elephants’ favorite food.	B．They are easily hurt by elephants.

D．Larger trees would defeat fast-growing species.

3. What did Mr. Berzaghi suggest people do?

A．Lead a low-carbon life.	B．Evaluate the carbon loss.
C．Stop destroying forests.	D．Protect forest elephants.

4. What is the best title for the text?

A．Humans and Nature Live in Harmony

B．Elephants Disappear in Parts of Africa

C．Climate Change Affects Forest Structure

D．Elephants Defend Against Climate Change

8 . Many people often find themselves waking up in the middle of the night, unusually awake and excited.     1     . That's really frustrating. However, there is no need to worry. Here are some effective ways to help you fall asleep again.

Remain in bed. For you to fall asleep, your heart rate needs to slow down. When you get up, your heart rate goes up. So, avoid going to the bathroom during the night if you can. Do not eat too little or too much for dinner. Do not drink and fill your bladder （膀胱）before bed.     2     . It may make you fall asleep faster, but it may also disrupt

your sleep later in the night.

Stay in the dark. When you cannot sleep, LED lights on printers and cable boxes may be the reason. The same is true for light streaming in through cracks in curtains.     3    . You should cover lights with tape and wear a sleep mask. A popular choice has deep eye cups so your eyes can open and shut while you wear them.

Quiet your mind. Try ways to relax, such as deep breathing, meditation, and mindfulness exercises.     4     . The point is to keep your brain busy with something that is not demanding and is relaxing.

    5     . If your wake-up time is 6:30 a.m. and your clock reads 3:00 a.m., do not think Oh no! I have only three hours left! Instead, say to yourself Oh great! I have three more hours to sleep!

You have a problem if you wake three times a week for more than three months. It may affect your quality of life. You need to find a sleep expert who can help identify the cause and fix it.

9 . Last Sunday, there was no dirt in the air, only bright spring sunshine and a clear blue sky. After church, Papa headed out to the field to check on the cattle while Mama started dinner.

________, Papa’s face appeared at the window. My heart jumped with surprise and ________. He opened the door and climbed onto the seat next to me. He coughed and wiped his eyes with dirty hands，then pulled me into his arms. “Oh, Iris, you’re ________.”

I hugged Papa and ________. I could feel the tears streaming down my dirty cheeks. Papa ________ my face. “Your mother and Faye?” I said, “They are in the house.” Papa nodded, “Good. We’ll wait out the storm there.” Papa shut off the car’s lights and I worried the dirt would ________ us.

Finally, the wind died down and the dust started to ________. Papa kicked against the door, opening it far enough to let us out. We went home as Mama ________ out. “Mama!” I shouted and ran into her arms. “Oh，my precious Iris!” Mama cried. “You and Papa are safe!”

10 . Lego is considering a brick (积木) rental plan in an attempt to cut down on plastic waste. The Danish toymaker has promised to make all its bricks from sustainable (可持续的) sources by 2030 and is investing significant resources into finding alternatives.

Tim Brooks, vice-president responsible for sustainability, said the company was “totally open” to the idea of a product rental plan but admitted that lost pieces could produce a significant problem. “What are the chances of giving them to an eight-year-old child and getting them all back again?” Mr. Brooks added.

“There is a lot of technical thinking that needs to be done. We are right at beginning of that.” Mr. Brooks said Lego was exploring several ideas with a view to producing the highest value from products while consuming the least amount of resources. He said many would “probably never see the light of day” and there was no current plan to try out a rental plan.

Lego has come under increasing pressure to reduce its carbon footprint among growing international alarm about the impact of plastic waste on the environment. It produces 19 billion pieces per year—36, 000 a minute—that are made entirely of plastic while much of the inside packaging is also plastic.

So far, the only breakthrough has been the development of a line of bricks made from plant-based plastic sourced from sugarcane. The green trees, plants and flowers were first included in Lego sets late last year but make up only 1%-2% of the total amount of plastic elements produced. Henrik Nielson, a production supervisor (主管) in Lego’s factory, said last year: “We need to learn again how to do this.”

Lego reportedly releases around a million tons of carbon dioxide each year, with about 75% coming from raw materials that go into factories. The company has invested more than 100, 000,000 euros and hired 100 people to research non-plastic alternatives. It is aiming to keep all of its packaging out of landfill by 2025.
