“Hey, don’t read in the hallway. Your ey...

    “Hey, don’t read in the hallway. Your eyesight will be damaged.” You must have heard such warnings many times. Don’t read in dim (暗的)light! This is one of the “pearls of wisdom” that are supposed to help us live a healthy life. Such common beliefs, however, lack scientific basis, according to a paper published recently in the British Medical Journal.

Do you believe in the following everyday wisdom?

Reading in dim light ruins your eyesight.

In dim light, you might blink (眨眼) more, feel discomfort from drying and have trouble focusing. But the majority of eye experts believe it is unlikely to do any permanent damage.

We must drink at least eight glasses of water a day.

In 1945, the Nutrition Council in US suggested that people need to consume 2.5 litres of water a day. But the water contained in food, particularly fruit and vegetables, as well as in milk, juice and soft drinks, also counts towards the total.

We only use 10 percent of our brains.

This myth arose as early as 1907. People have long argued about our power of self-improvement and our brains’ potential abilities. But detailed imaging shows that no area of the brain is silent or inactive.

Shaving your legs causes hair to grow black faster and thicker.

This theory is also illusion. Shaving has no effect on the thickness or rate of hair growth, studies say. Just over time, the edge of hair gets worn away and thus the edge of long hair becomes finer (更细). So hair that is newly grown gives the impression of darkness.

1.What does the paper say about some common beliefs?

A.They are pearls of wisdom

B.They help us live in healthy ways

C.They are well-known theories.

D.They do not have scientific basis.

2.Which of the following is true according to the passage ?

A.Reading in dim light does permanent harm to one’s eyes.

B.People need a total of 2.5 litres of water a day

C.People use 90 percent of their brains.

D.Shaving your legs will give you thicker hair.

3.Why does newly-grown hair look thicker?

A.Because it is darker.

B.Because it grows faster.

C.Because its edge isn’t worn away.

D.Because shaving has an effect on it.

4.This passage is most likely to be found in __________.

A.a newspaper B.a science fiction

    Environmental experts warn that our planet is drowning in plastic.

The world’s cities produce 2 billion tons of trash every year. By the year 2050 that number is expected to rise to 3 billion tons. The World Bank estimates that the largest amount of trash today, about 44 percent, is plastic. But we often have to buy packaged goods. And often that packaging is made of plastic.

Now, that may be changing. A new environmentally-friendly shopping model was recently launched at the World Economic Forum in Davos, Switzerland. This shopping model, called Loop, aims to replace throwaway containers with reusable ones.

Loop is the idea of Terra Cycle, an American-based recycling company. Its chief, Tom Szaky. told the Associated Press (AP) that “removing plastics from the ocean is not enough.” He said the point is to get away from single-use packages. Szaky said that Loop is the future of shopping. But it comes from an idea of the past.

He compared it to the “milkman model” of the 1950s in the United States. Back then, someone brought milk to your doorstep in glass bottles and then left with empty bottles. These could be cleaned and used again. The result is zero-waste.

Jennifer Morgan from the environmental non-profit organization Greenpeace also joined in the discussion about Loop at Davos. She said that “Greenpeace welcomes the aim of the Loop Alliance to move away from throwaway culture and disposability.” But Morgan questioned whether companies worldwide are ready to change their business models.

Loop is set to launch later this year in three eastern U.S. states, and also in Paris, France and some of the surrounding area. Then Loop plans to expand to the U.S. West Coast, Toronto, Canada and Britain by the end of this year or 2020.

1.What does the author intend to do in Paragraph 2?

A.Provide background information. B.Advocate zero-waste lifestyle.

C.Explain the reason for trash. D.Introduce a new topic.

2.Where does the idea “Loop” come from?

A.The World Economic Forum. B.Demand of some companies.

C.Zero-waste model. D.The milkman model.

3.Which countries is Loop expected to expand to by 2020?

A.United States and Switzerland. B.Switzerland and Britain.

C.Canada and Britain. D.France and Canada.

4.What is the text mainly about?

A.A new shopping model. B.The development of future city.

C.The world’s environmental issue. D.The concerns of future shopping.

    A day in the life of 18-year-old David Lanster is full of teenage activities: school, baseball practice, homework. And then he starts cooking. “Some nights I’m up until 1 a.m. making pies, or even later if we’re cooking beef,” said the student at Ransom Everglades High School in Florida, US.

For the past year, Lanster and Kelly Moran, his classmate, have been hosting fancy dinner parties at Lanster’s parents’ home. Their meals have 17 courses and are all made by them. Their guests used to give them gifts to thank them, until the pair decided to do something nice for charity. “We got some really great Miami Heat tickets, a nice watch, and many kitchen machines,” Lanster said. “But we wanted to make this something positive for people rather than us.”

Lanster and Moran focused on Common Threads, a charity(慈善机构) that helps to teach kids in poor neighborhood to cook and make healthy eating choices. The young cooks ask their guests to give however much they want as payment for their meals. It all goes to Common Threads because Lanster’s parents cover their food costs. After their last 12-person event, Lanster and Moran gave $1,600 to the charity. Now, they’re taking their show out of the kitchen and on the road. Lanster and Moran have started to organize private dinner parties in a similar way: the host pays for the ingredients(食材), and the guests make a donation (捐赠) to a charity.

Outside the kitchen, the two are busy preparing their college applications. Neither is sure what they will do in the future, but they’ve promised their parents that they’ll leave cooking alone until they finish high school.

1.Why does Lanster and Moran cook now?

A.To get gifts from guests. B.To raise money for charity.

C.To become cooks. D.To make healthier eating choices.

2.What can we infer about Lanster and Moran?

A.They will give up cooking forever.

B.They are sure about their future jobs.

C.Their parents support cooking as a job.

D.They will stop cooking for college application.

3.How can we best describe Lanster and Moran?

A.Selfish and reliable. B.Creative and helpful.

C.Confident and careful. D.Outgoing and patient.

4.What can be a suitable title for the text?

A.A Great Cook B.Eat as you Wish

C.Helping by Cooking D.Cooking for School Fees
