For many years, she was only interested in making money and material things. Then one day she had a s

2、erious car accident, which changed her life. Hill said: “I realized I wanted to find a more powerful purpose for being here on this planet.” As soon as she recovered, Hill traveled to California. There she saw ancient redwood trees, which are the largest trees in the whole world. The wood from redwo

3、od trunks is very hard. So the Pacific Lumber Company cut down many of the huge redwoods to use for construction. There are not many forests of these trees left. Many environmental activists want to protect the remaining trees. The redwoods are very important to the environment. In 1997 Hill learned

4、 a group called Earth First was working to protect a particular group of trees. They decided to send someone up into a redwood tree, hoping this would stop the company from cutting the trees down. Julia Butterfly Hill volunteered. Hill lived in the tree for over two years without ever coming down. H

5、er home was a 6-by-8-foot tree house, 180 feet up. It is always cold and wet in a redwood tree. There were even very serious winter storms while Hill was in the tree. The wind and cold almost knocked Hill out of the tree. But she did not fall she survived. Finally, after years of arguing, the compan

Some, however, are a little sillier than others so much that they seem like joke products. Here are a few products that sound crazy, but actu

10、ally rule.Sleep Phones Its hard to imagine something sillier than a music-playing headband you wear while you sleep, but they exist and are quite popular. Sleep Phones wont give you the highest quality sound in the world, but if you prefer to fall asleep to music, theyre far more comfortable than no

11、rmal headphones. While theyre a bit expensive, they might be perfect for you. Theres also a wireless version (版本) if you prefer.Onion Goggles If cutting onion brings on the waterworks no matter what you try, its time for desperate measures. We tested a bunch of methods for avoiding onion tears, and

12、found the best solutions came down to cutting the onion under a vent (通风孔), or wearing these stylish and awesome goggles.Lock Laces Therere some great ways to tie your shoes better, but if you long for the laceless shoes of your childhood days, Lock Laces are a pretty good choice. Theyre basically e

13、lastic (有弹性的) laces that remove the need to tie your shoes. Sure, people will make fun of you, but you can make fun of them after they trip over their own untied laces. Or you can make your own slip-on shoes with elastic tubing.2D-Glasses Hate 3D-movies, but have to go to one? The difference between

14、 2D-glasses and 3D-glasses lies in their lenses (镜片). Each lens of 2D-glasses blocks the same picture, so each eye gets the same picture, while each lens of 3D-glasses blocks a different picture, so each eye gets a different picture which the brain interprets as 3D. Now you have a pair of glasses th

15、at can save you from the headache caused by wearing 3D-glasses which are popular in our movie theaters. You can buy them or make a pair for yourself.25. What do we know about Sleep Phones?A. There are two versions.B. Theyre comfortable but unhealthy.C. They give you the best quality sound.D. Theyre

16、cheaper than other headphones.26. The underlined part “brings on the waterworks” in the text probably means _.A. makes your eyes waterB. makes your fingers hurtC. destroys your water pipesD. adds to your washing work27. What is the advantage of Lock Laces? A. They are strong and lasting.B. They help

17、 you walk comfortably.C. They are stylish and eco-friendly.D. They save you from tying your shoes.28. Compared with 3D-glasses, 2D-glasses _.A. are cheaper and thinnerB. wont give you a headacheC. let you see a different pictureD. are more popular in movie theatersC A team led by a nurseryman (花圃工人)

18、 and his sons has raced against time for 20 years, using branches from some of the worlds biggest and most long-lasting trees to produce clones that could restore ancient forests and help fight climate change. Now comes the most ambitious step of the project: getting the new trees into the ground. P

19、lantings of two dozen clones from Californias huge coastal redwoods will take place Monday in seven nations: Australia, New Zealand, Great Britain, Ireland, Canada, Germany and the U.S. The lab-produced trees are genetic copies of three huge trees that were cut down in northern California more than

20、a century ago. Remarkably, new branches still grow from the stumps (树桩), including one known as the Fieldbrook Stump, which measures 35 feet in diameter (直径). Its believed to be about 4,000 years old. “We need to reforest the planet. To do that, it just makes sense to use the largest, oldest trees t

21、hat ever lived,” said David Milarch, co-founder of the non-profit Archangel Ancient Tree Archive. Milarch and his sons Jared and Jake, who have a family-owned nursery, became concerned about the condition of the worlds forests in the 1990s. They began traveling across the U.S. in search of “champion

22、” trees that have lived hundreds or even thousands of years, believing that better genes make it possible for them to outlive others of their species. Scientific opinion varies on whether thats true, with skeptics saying the survivors may simply have been lucky. The Archangel team says theyve develo

23、ped several methods of producing genetic copies. They focus on towering sequoias and redwoods, considering them best suited to absorb great amounts of carbon dioxide (CO2), the greenhouse gas primarily responsible for climate change. The challenge is to find places to put the trees, people to look a

24、fter them and money to continue the project, Jared Milarch said. The group is funded through donations and doesnt charge for its clones. “A lot of trees will be planted by a lot of groups on Arbor Day, but 90 percent of them will die,” David Milarch said. “You cant plant trees and walk away and expe

25、ct them to take care of themselves.” Those receiving Archangel redwoods have promised to care for them properly. 29. According to the text, the clones _. A. are rather expensiveB. are based on dead ancient treesC. have been experimented for 20 yearsD. have been widely grown across the U.S.30. To ref

David Milarchs team believes that genetic copies from sequoias and redwoods _. A. can take in more greenhouse gasesB.

The need of financial support. B. The difficulty of finding places.C. The importance of caring for trees.D. The challenge of r

28、unning his group.D During the Middle Ages, most things that people did not understand were explained through religion. The Catholic Church sought to silence those who tried to understand and explain the world in natural terms, and banned dissection (解剖) of humans. Leonardo da Vinci was one of the fi

29、rst people of the Renaissance to use the modern scientific method. He carefully observed nature, conducted experiments, and arrived at conclusions. His research unavoidably brought him into conflict with the Church. Leonardo spent his life studying the world around him and filled many notebooks with

30、 drawings and ideas inspired by nature. He studied human anatomy (人体解剖学) by dissecting dead bodies, made detailed notes, and drew large numbers of pictures to explain. He studied the flight and anatomy of birds in order to design a flying machine. He was not successful, although he tried out several

31、 strange-looking machines. As a scientist, Leonardo made great contributions in the fields of anatomy, botany (植物学) and physics. Leonardo was the first person to note that the number of rings of a tree was the same as its age. He was also the first person to describe the arrangement of leaves in plants and draw parts of the body in cross-section. Leonardo was also a great inventor. He did not seek simply to better understand the world. He wanted to change it through the invention of new and useful machines. H
