Question

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(胰島素) in the body, which we think contributes to pancreatic cancer cell growth,” President said in a statement.
Writing in the journal Cancer Epidemiology, Biomarkers & Prevention, Pereira and his 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 sweetened 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.
“Although this study found a risk, the finding was based on a relatively small number of cases and it remains unclear whether it was a causal(因果的) connection or not.” Said Mayne, who serves on thee board of the journal, which is published by the American Association for Cancer Research.
Pancreatic cancer is one of the deadliest form of cancer, with 230,000 cases globally. In the United States, 37,680 people are diagnosed with pancreatic cancer in a year and 34, 290 die of it.

B．Doubtful

C．Worried

D．Hopeful

【小題3】The best title of the text might be_______

A．The Deadliest Forms of Cancer

B．Drink Fruit Juice Instead of Sodas

C．A Study in University of Minnesota

Answer 1

【小題1】D
【小題2】B
【小題3】D

解析試題分析：研究人員通過調(diào)查發(fā)現(xiàn)：每周喝兩瓶或更多含糖軟飲料的人患胰腺癌的幾率會(huì)更高。而且指出在西方其他國(guó)家應(yīng)該存在同樣情況。但是也有人提出異議，認(rèn)為通過研究這么少的病例不足以證實(shí)飲用含糖軟飲料和胰腺癌之間存在必然的因果關(guān)系。
【小題1】D推理判斷題。“Sugar may be to blame but people who drink sweetened sodas regularly often have other poor health habits,”意思是糖應(yīng)該承擔(dān)責(zé)任（在患胰腺癌方面），但是那些喜歡喝含糖飲料的人經(jīng)常有其他不良飲食習(xí)慣。由此可知其他的不良飲食習(xí)慣也會(huì)導(dǎo)致胰腺癌的發(fā)病，所以D選項(xiàng)正確。
【小題2】B細(xì)節(jié)理解題。從“the finding was based on a relatively small number of cases and it remains unclear whether it was a causal(因果的) connection or not.”可知Susan認(rèn)為研究的病例比較少，含糖軟飲料和胰腺癌之間的關(guān)系還有待于進(jìn)一步證實(shí)，所以她是持懷疑態(tài)度的。B選項(xiàng)正確。
【小題3】D主旨大意題。?文章開頭提出中心People who drink two or more sweetened soft drinks a week have a much higher risk of pancreatic cancer ，然后再進(jìn)一步敘述研究細(xì)節(jié)詳情等，所以D選項(xiàng)正確。
考點(diǎn)：考查科學(xué)知識(shí)類短文閱讀。
