【1】　Margaret Sanger and Birth Control

　　Margaret Sanger, an American nurse, was the first to start the modern birth control movement in the United States. In 1912 she (1) publishing information about women's reproductive (生殖的) concerns through articles and books. In 1914 Sanger was charged (2) violation of, the Comstock Law, which federal legislation had passed in 1873 forbidding the mailing of sexy material (3) information about birth control and contraceptive (避孕的) devices. Though she was put in jail for these activities, Sanger (4) to publish and spread information about birth control. She and her sister Ethel Byrne opened the first of several birth control clinics in America on October 16, 1916, in Brooklyn, New York.

　　The Comstock Law was rewritten by Congress in 1936 to (5) birth control information and devices. Many states had laws forbidding distribution or use of contraceptive devices but the constitutionality (合宪性) of these laws was increasingly (6). In 1965, the Supreme Court of the United States ruled that married people have the right to practice birth control without government intervention. In 1972, the court (7) that unmarried people have the same right.

　　Today there are more birth control options (8), but overpopulation and unwanted pregnancies remain worldwide (9). Having more children than one can support may lead (10) poverty, illness, and high death rates for babies, children, and women.

　　The problem of teenage pregnancy is (11) worse in the United States (12) in almost any other developed country. Studies show that birth rates for women under 20 are higher in the United States than in 29 other (13) countries. A detailed study suggested that the problem of teenage pregnancy in the United States may be (14) to less sex education in schools and lower availability (可获性) of contraceptive services and supplies to young people. This study (15) the view of people in the United States who argue that sex education or making contraceptive supplies available to school-age children promotes sexual activity.

【2】　Cell Phone Lets Your Secret Out

　　Your cell phone holds secrets about you. Besides the names and 51 that you've programmed into it, traces of your DNA linger on the device, according to a new study.

　　DNA is genetic material that 52 in every cell. Like your fingerprint, your DNA is unique to you-- 53 you have an identical twin. Scientists today routinely analyze DNA in blood, saliva, or hair left 54 at the scene of a crime. The results often help detectives identify 55 and their victims. Your cell phone can reveal more about you 56 you might think.

　　Meghan J. McFadden, a scientist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone and later dropped the 57 This made her wonder whether traces of DNA lingered on cell phones--even when no blood was involved. 58 she and colleague Margaret Wallace of the City University of New York analyzed the flip-open phones of 10 volunteers. They used swabs to collect 59 traces of the users from two parts of the phone: the outside, where the user holds it, and the 60 , which is placed at the user's ear.

　　The scientists scrubbed the phones using a solution made mostly 61 alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got ,Heir phones 62 for another week. Then the researchers collected the phones and repeated the swabbing of each phone once more.

　　The scientists discovered DNA that 63 to the phone's speaker on each of the phones. Better samples were collected from the outside of each phone, but those swabs also picked up DNA that belonged to other people who had apparently also handled the phone. 64 , DNA showed up even in swabs that were taken immediately after the phones were scrubbed. That suggests that washing won't remove all traces of evidence from a criminal's device. So cell phones can now be added to the 65 of clues that can clinch a crime-scene investigation.
