14．A study showed eating even a little less salt could greatly help the heart．The study was published in the New England Journal of Medicine．The scientists used a computer model to predict how just three grams less salt a day would affect heart disease in the United States．
The scientists said the results would be thirteen percent fewer heart attacks，eight percent fewer strokes （中风），four percent fewer deaths and eleven percent fewer new cases of heart disease（710C．Researchers said it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year．The researchers were from the University of California，San Francisco，Stanford University and Columbia University．They and public health professionals in the United States are interested in a national campaign to persuade people to eat less salt．（72）B．
However，some scientists say such a campaign is an experiment with the health of millions of people．
Michael Alderman is among the critics（批评家）．He is a high blood pressure expert and professor at Albert Einstein College of Medicine in New York．Doctor Alderman says that eating less salt results in lower blood pressure．（73）G．
And he says salt has other biological effects．He says calling for reductions in the national diet could have good effects，but it could also have harmful results．
Another critic is David McCarron，a nutrition and kidney （肾） disease expert at the University of California．He and his team looked at large studies of diets in thirty-three countries．（74）F．Most of them eat more salt than American health officials advise．
Doctor McCarron says the worldwide similarity suggests that a person's brain might decide how much salt to eat．
Both Doctor McCarron and Doctor Alderman have connections to the Salt Institute，a trade group for the salt industry．Doctor Alderman is a member of an advisory committee．（75）A Doctor McCarron is paid for offering scientific advice to the Salt Institute．

A．But he says he receives no money from the group．
B．Such campaigns are already in place in Britain，Japan and Finland．
C．And two hundred forty billion dollars would be saved in health care．
D．They say people eating less salt have equal chances to have diseases．
E．And it may also result in fifteen percent increase of the kidney death rate．
F．They found that most people around the world eat about the same amount of salt．
G．But he says studies have not clearly shown that lowering salt means fewer heart attacks or strokes．

8．In a class this past December，after I wrote some directions on the board for students about their final examination，one young woman quickly took a picture of the board using her smart phone．When I looked in her direction，she apologized，"Sorry．Was it wrong to take a picture？"
"I can't read my own handwriting，"the young woman explained．"It's best if I take a picture of your writing so I can understand the notes．"
That remark started a class-wide conversation about taking a picture instead of taking notes．For those in the photo-taking camp，motivations extended beyond their inability to comprehend their own handwriting．Some took pictures of notes because they knew their phone was a safe place to store material．They might lose paper，they reasoned，but they wouldn't lose their phones．Some took photos because they wanted to record exactly the manner in which I had noted information on the board．Others told me that during class they liked to be able to listen to the discussion attentively．
Yet the use of cameras as note takers，though it may be convenient，does raise significant questions for the classroom．Is a picture an effective replacement for the process of note-taking？
Instructors encourage students to take notes because the act of doing so is more than merely recording necessary information-it helps prepare the way for understanding．Encouraging students to take notes may be an old-fashioned instructional method，but just because a method has a long history doesn't mean it's out of date．Writing things down engages a student's brain in listening，visual，and kinesthetic（触觉的） learning-a view supported by a longstanding research．The act of writing down information enables a person to begin committing it to memory，and to process and combine it，establishing the building blocks of learning new concepts．
Taking a picture does indeed record the information，but it deletes some of the necessary mental engagement that taking notes employs．So can the two be equally effective？
28．The woman apologized in the class because sheA．
A．took a picture of the board
B．missed the teachers'directions
C．had the bad handwriting
D．disturbed other students'learning

A．They believe smart phones are much safer for storing notes．
B．They want to listen more attentively in class．
C．They lack proper techniques for taking notes．
D．They want to have the exact version of the notes on the board．
30．According to the passage，taking notes by handD．
A．requires students to think independently
B．seems unsuitable for students to learn new ideas
C．proves to be an old and useless learning method
D．helps students actively participate in learning
31．What is the main idea of this passage？B
A．The traditional way of note-taking should be replaced．
B．Note-taking by hand is not out of date．
C．A modern way of note-taking is catching on．
D．A picture is worth a thousand words．
