“What Darwin Saw” tells of the adventures of a young man who traveled around the world as a scientist. The voyage of the Beagle took Charles Darwin to South America， where he rode horses with cowboys and met Native Americans in Argentina. He reported the eruption of the Osorno Volcano and experienced an earthquake in Chile. Darwin’s observations showed him that environments can change very quickly and a great deal over time.
Rosalyn Schanzer brings to life the clues that suggested to Darwin that living things evolve， or change， over time. She illustrates the unusual tortoises， birds and lizards that Darwin studied in the Galapagos Islands. She shows how Darwin came to understand that these island animals had differences， developed over time， that helped them survive. And she explains the theory of evolution through natural selection in a way that both children and adults will enjoy.

Reader Janet Maynard has a lot of young bushes in her garden and is suffering from “watering can elbow”. So for Janet and anyone else who doesn‘t want to waste time， effort and water， here are my top tips for keeping plants refreshed in thirsty times.
Water in the evening if possible， rather than leaving it till you see things suffer. That way the roots can take up the water in cool soil overnight.
Violently jetting hoses（皮管）mess up the soil structure and may expose delicate roots. Use a rose（喷头）on a can. Aim low – don‘t waste water wetting leaves， even though they look pretty and ”refreshed”.
The most valuable and easily damaged plants need the most attention， such as newly planted trees， bushes and climbers. Remove any water-keeping mulch（护根物）you may have put around the base， then water it thoroughly at least two gallons， slowly. Don‘t aim your can rose at the stem – which we all usually tend to do. Aim the water in a wide circle so that the whole of the area under the plant is watered. You could even make a channel in the soil right around the plant so that the water is held in place as it soaks（浸透）in. Replace the mulch. Repeat each week even in showery weather for the first summer.
How much water for pots? Fill up the gap between the top of the soil and the top of the pot. Let the water soak right in and then fill it again. Do this daily in hot weather for most summer potted plants.
Stand pots in saucers（垫盘）– it makes a big difference. But remember to check that the plants are not sitting in water for days on end when the weather turns wet. Roots will rot.
If the fertilizer in pots really dries out， the water may get straight out of the pot without being absorbed. Correct this by standing or floating the pot in a bucket of deep water until it sinks and no bubbles rise.
A push-button watering can makes for more efficient watering， and recycled water bottles upside down with a needle which has a hole on the end are useful， too， for pots.
64. What does the underlined part “watering can elbow” in Paragraph 1 most probably mean?
A. A certain kind of mental diseaseB. The extreme thirst for water.
C. The power of water.D. Tiredness or pain in part of the body.
65. Which of the following statements is NOT true according to the passage?
A. It would be better to water the plant in the evening than in the morning.
B. It’s necessary to water newly-planted trees once a week in the first summer.
C. Put potted plants in saucers in case the roots rot in damp weather.
D. Make sure fertilizer in the pot doesn’t dry out， otherwise the water would not be fully absorbed.
66. We may easily learn from the passage that _______.
A. potted plants need to be watered every week even in rainy weather.
B. we’d better put water on the leaves and stems to keep the plants refreshed.
C. It’s better to use a rose on a can to water than jetting hoses.
D. people usually don’t want to waste time， effort and water in raising plants.
67. What can be the best title of this passage?
A. The importance of water in caring for plantsB. Watering tips and skills
C. How to take care of your plantsD. The relationship between plants and water

WASHINGTON (Reuters) – People who drink two or more sweetened soft drinks a week have a much higher risk of pancreatic cancer (胰腺癌)， an unusual but deadly cancer， researchers reported on Monday.
People who drank mostly fruit juice instead of sodas did not have the same risk， the study of 60，000 people in Singapore found.
Sugar may be to blame but people who drink sweetened sodas regularly often have other poor health habits， said Mark Pereira of the University of Minnesota， who led the study.
”The high levels of sugar in soft drinks may be increasing the level of insulin（胰岛素）in the body， which we think contributes to pancreatic cancer cell growth，” Pereira said in a statement.
Writing in the journal Cancer Epidemiology， Biomarkers & Prevention， Pereira and colleagues said they followed 60，524 men and women in the Singapore Chinese Health Study for 14 years.
Over that time， 140 of the volunteers developed pancreatic cancer. Those who drank two or more soft drinks a week had an 87 percent higher risk of being among those who got pancreatic cancer.
Pereira said he believed the findings would apply elsewhere.
”Singapore is a wealthy country with excellent healthcare. Favorite pastimes(消遣) are eating and shopping， so the findings should apply to other western countries，” he said.
But Susan Mayne of the Yale Cancer Center at Yale University in Connecticut was cautious.
