Exercise early in life seems to have lifelong benefits for the brain，in rats at least.“This is an animal study，but it shows that physical activity at a young age is very importantnot just for physical development，but for the whole lifelong track of cognitive(認(rèn)知的)development during ageing，”says Martin Wojtowicz of the University of Toronto，Canada. “In humans，it may delay the appearance of Alzheimers disease(阿爾茨海默病)，possibly to the point of preventing it.”Wojtowiczs team divided 80 young male rats into two equal groups，and placed running wheels in the cages of one group for a period of six weeks.Around four months laterwhen the rats had reached middle agethe team taught all the rats to connect an electric shock with being in a specific box.When placed in the box，they froze with fear.Two weeks later，the team tested the rats in three situations：exactly the same box in the same room，the same box with the room arranged differently，and a pletely different box in a different room.The rats without access to a running wheel when they were young now froze the same percentage of times in each of these situations，suggesting they couldnt remember which one was dangerous.But those that had been able to run in their youth froze 40 to 50 percent less in both changed box settings.“The results suggest the amount of physical activity when were young，at least for rats，has influence on the brain and cognitive healthin the form of better memorieswhen were older，” says Arthur Kramer of Northeastern University in Boston，who has found that，in humans，exercise promotes the growth of new brain cells.1The study shows that _.Aphysical activity is important for physical healthBusing the running wheels is of benefit to the rats growthCphysical activity can prevent humans Alzheimers diseaseDthe more exercise a rat has when young，the better memory it will possess when older2How are Paragraph 3 and 4 mainly developed?ABy analyzing causes.BBy giving an example.CBy describing the process.DBy showing differences.3What does the underlined word “it” in Paragraph 2 refer to?AExercise.BDevelopment.CBenefit.

him.第一處：are改為is。考查主謂一致。whose引導(dǎo)的定語(yǔ)從句的先行詞是代詞“one”，因此謂語(yǔ)動(dòng)詞應(yīng)該用單數(shù)。第二處：because改為that?？疾槊~性從句。主語(yǔ)為名詞reason，表語(yǔ)從句中的連接詞要用that。第三處：smile改為smiles。考查動(dòng)詞時(shí)態(tài)和主謂一致。由“which makes
