2. If a person’s ability against sunlight is 30 minutes, how long is the ability of another one who is often eaten tomato paste? 1010jiajiao
A. About 40 minutes. B. Less than 20 minutes. 1010jiajiao

1. What’s the best title of the passage? 1010jiajiao

B. Eating tomatoes is the best way to avoid sunburn and wrinkles. 1010jiajiao

D. Eating fruits is the best way to avoid sunburn and wrinkles. 1010jiajiao
The effect of eating tomatoes was equivalent to slapping on a factor 1.3 sunscreen. Changes were also seen within the skin of the volunteers that counteract the appearance of ageing. 1010jiajiao
Scientists think an antioxidant, lycopene（番茄红素）, which gives tomatoes their color, can neutralize harmful molecules produced in skin when exposed to the sun’s ultra-violet rays. Damage inflicted by the free radical molecules on skin structures and DNA can lead to premature ageing and skin cancer. 1010jiajiao
Previous research has shown that cooked tomatoes contain higher levels of lycopene than raw tomatoes. Tomato paste of the sort used to make pizza toppings is rich in lycopene. Skin levels of procollagen（原骨胶原），which helps the skin stay supple and youthful, were also boosted by the tomato diet. 1010jiajiao
At the same time tests at the University of Newcastle showed that lycopene reduced sun damage to mitochondrial DNA in the skin―DNA in tiny power plants in cells called mitochondria. Its disruption is also associated with skin ageing. 1010jiajiao
Professor Lesley Rhodes, at Manchester University, said, “The tomato diet boosted the level of procollagen in the skin significantly. These increasing levels suggest potential reversal of the skin ageing process. ” 1010jiajiao

Eating pizza topped with tomato paste can help prevent sunburn and premature wrinkles, new research suggests. 1010jiajiao
A study found that volunteers who ate ordinary tomato paste over a 12-week period developed skin that was less likely to burn in the sun. 1010jiajiao
Researchers at the University of Manchester found that the subjects were 33 percent more protected against sunlight than another group who were not given tomato paste. 1010jiajiao

Today we begin a series of programs about learning disabilities．These are disorders in the ways that people understand or use language．They can affect the ability to listen or think, or to speak or to read and write．They can also affect the ability to do mathematics．A person with a learning disability has unusual difficulty in developing these skills．Researchers believe that learning disabilities are caused by differences in the way that the brain works with information． They say children with learning disabilities are not unintelligent or do not want to work．Their brains just process information differently than other people． 1010jiajiao
Researchers say that as many as one out of every five people in the United States has some kind of learning disability．Almost three-million children in the United States receive some kind of help in school for a learning disability． 1010jiajiao
How can you tell if someone has a learning disability? Expels look for a difference between how well a child does in school and the level of intelligence or ability of the child．But there is no one sign of a disorder．A few signs of learning disability include not connecting letters with their sounds or not understanding what is read．A person with a learning disability may not be able to understand a funny story．They may not follow directions．They may not read numbers correctly or know how to start a task．Different people have different kinds of learning disabilities．One person may have trouble understanding mathematics．Another may have difficulty understanding what people are saying．Still another may not be able to express ideas in writing．These different kinds of learning disabilities are known by different names．For example，a person who has difficulty reading may have dyslexia． 1010jiajiao
Experts say learning disabilities cannot be cured．But people who have them can be helped．Teachers and parents can help young people with learning disabilities to learn successfully． 1010jiajiao
