Develop a plan.
Successful men and women are both effective and efficient. 4. Develop a plan, then decide what is the most important thing to do and how to do it.
5.

A. Focus on the key tasks.
B. Start from small things.
C. They do the right things in the right way.
D. But never forget to learn from their failures.
E. However, the truth is that we have much to learn.
F. Study the interviews, speeches, biographies of them.
G. Here are several ways to get organized and get started.
Elephants have impressed us for centuries. They are big, clever, and sociable. But what if someone told you that they may also hold the key to fighting cancer (癌症)?
People have been wondering why elephants do not develop cancer, even though they have lifespans (寿命) that are similar to humans, living for around 50 to 70 years.
Now scientists believe they know why. A team at the University of Chicago, US has found that elephants carry a large number of genes that stop tumors (肿瘤) from developing. To be precise, they found 20 copies of an antitumor gene called TP53 in elephants. Most other species, including humans, only carry one copy.
According to the research, which was recently published on the online science network BioRxiv, the extra copies of the gene improved the animal's sensitivity to DNA damage. This lets the cells quickly kill themselves when damaged before they can go on to form deadly tumors.
“An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals，” study author Dr. Vincent Lynch told The Guardian. If every living cell (细胞) has the same chance of becoming cancerous, large creatures with long lifespans like whales and elephants should have a greater risk of developing cancer than humans and mice do. But across species, the risk of cancer does not show a connection with body mass.
This_phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named “Peto's paradox”. Evolutionary (进化的) biologists believe it results from larger animals using protection that many smaller animals do not. In the elephant's case, the making of TP53 is nature's way of keeping this species alive.
The study also found that when the same genes were brought to life in mice, they had the same cancer resistance (抵抗) as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers from spreading or even developing in the first place.
“Nature has already figured out how to prevent cancer, ” said Joshua Schiffman, an oncologist at the School of Medicine, University of Utah, US.
“It's up to us to learn how different animals tackle (处理) the problem so we can use those strategies to prevent cancer in people.”
1.Why are elephants unlikely to develop cancer?
A. They have a large body size.
B. Their genes suffer no DNA damage.
C. Certain genes in their body kill existing tumors.
D. They carry many genes that keep tumors from developing.
2.According to Dr. Vincent Lynch, what has been a risk in the evolution of large animals?
A. A risk of deadly tumors. B. Human behavior.
C. Extreme weather. D. Cells killing themselves.
3.What does the underlined expression “This phenomenon” in the sixth paragraph refer to?
A. Larger animals have protection from TP53.
B. The risk of cancer is not related to body size.
C. The larger animals are, the bigger risk of cancer they have.
D. Larger animals suffer the same risk of cancer as smaller ones do.
4.We can conclude from the last three paragraphs that ________.
A. humans are expected to stop cancer in the near future
B. depending on nature is not enough to fight against cancer
C. this new treatment is more effective than the present ones
D. the TP53 genes have proven useful in stopping cancer in mice
A company in San Francisco, California, has found a way to turn used plastic bottles into women’s shoes.
Every day, millions of Americans drink water and other liquids from plastic bottles. More than 60 million of them are thrown away each day. Many of the plastic bottles end up in landfills or are burned with other waste products.
A San Francisco start-up company called Rothy’s, however, turns this plastic waste into environmentally friendly shoes. Rothy Martin is the company’s co-founder. He explains how they turn plastic into soft material for your feet. They take the plastic, clean it, and break it down into small pieces. Then they press it through a device that makes soft fibers. Those fibers are then combined, or knit together. This is done by a three-dimensional knitting machine. It is designed to reduce waste while making the shoes.
The knitted fabric and the inner part of the shoes are then attached to the shoes’ outer part, called the sole. This outer sole is also made from environmentally friendly material: responsibly sourced no-carbon rubber.
Rothy’s shoes are sold online. They are flat shoes, with either a rounded or pointed toe. They come in different colors and designs. They cost either $125 or $145 per pair, depending on the design.
After American actress Gwyneth Paltrow discovered them last year, the demand for the shoes grew.
Martin says there is no shortage of material to fill that demand. “We’re not going to run out of water bottles any time soon. So we have an infinite supply of material, and I think that bodes well for our future. ”
When the environmentally friendly shoes wear out, customers can return them at no cost to a company that uses the recycled materials to make other products.
For now, the shoes are only available to be shipped in the United States. However, the company says it will add international shipping in the near future.

2.Why did Rothy’s use a three-dimensional knitting machine to make shoes?
A. Because it is easy to operate.
B. Because it is cheaper than other machines.
C. Because it is productive.
D. Because it can reduce waste when making the shoes.
3.What can be learned from the passage?
A. This kind of shoes are sold in the shop.

D. The shoes are available in the world.
