A.夏季风势力弱

B.受副高控制时间长

C.受台风影响大

D.受气旋活动影

答案

小题1:B

小题2:B

小题3:B

本题考查我国的区域地理和读图分析能力。

小题1:根据图示的经纬度位置判断,该地区位于我国南方低山丘陵地区,故地势起伏大,不利于交通运输发展。

小题2:我国南方地区受亚热带季风气候影响,雨热同期,利于农业生产。

小题3:影响我国东部地区的降水量的变化主要是由于副高推动的夏季风不太稳定,我国南方干旱,反映副高势力强,长期控制南方地区,而雨带推移到北方,故形成南旱北涝。

The “issues” reported were unthinkable. The physician who enrolled the most patients in the study, an Alabama weight-loss doctor, allegedly forged scores of signatures, enrolling “volunteers” every few minutes.

By the time of the FDA review, she was under criminal investigation. (She’s now in federal prison. ) Another key researcher had been put on probation by the California medical board for gross negligence. He was arrested shortly after the study ended, when police, called to his home on a domestic violence complaint, found him with a bag of cocaine and waving a loaded gun at imaginary people. The study was so riddled with fraud and error that FDA reviewers decided it was useless.

Yet Dr. Ross says he was told to reveal nothing about those problems to the advisory board, which recommended that the drug be approved. Later, he says, he was pressured to soften his report about Ketek’s liver toxicity to gain approval of higher-ups. Six million Americans have now used the drug, including hundreds of infants in a clinical trial designed to test Ketek’s effectiveness against ear infections. "How does one justify balancing the risk of fatal liver failure against one day less of ear pain" one FDA scientist, Rosemary Johann-Liang, protested—to no avail—in a memo to her superiors. Most ear infections clear up in a few days on their own, she says.

The agency says the controversy is overblown. "There was enough good, solid scientific data to make that decision. " Says FDA spokeswoman Julie Zawisza, pointing to what appeared to be a history of safe use of Ketek in other countries. Ketek has now been linked to 18 deaths and at least 134 cases of liver damage, according to an independent analysis using FDA data. The real toll, some researchers say, may be far greater.

Last October the FDA sent a warning letter to Sanofi-Aventis, Ketek’s maker, accusing the company of knowingly presenting compromised data to the agency, a charge the company denies. "We were not aware of the fraud," says spokeswoman Melissa Feltmann. "It was not until the FDA’s criminal investigators uncovered it that we became aware of it. "

The question remains, what did the FDA and the drugmaker know about the fake safety data, and when

Congressmen John Dingell and Bart Stupak, both Michigan Democrats, are investigating that mystery right now in Congressional hearings.

"Unfortunately. " Stupak says, "the truth comes too late for some victims. \

According to Paragraph 1, the Alabama physician was accused of().

A. forcing people to join his study

B. administering illegal drugs to patients

C. exaggerating some drug’s effects

D. inventing evidence for her research
