Unfortunately, L.A.Unified has produced an inflexiblepolicy which mandates that with the exception of some advanced courses, homework may no longer count formore than 10% of a student's academic grade. This rule is meant to address the difficulty that students from impoverished or chaotic homes might havein completing their homework. But the policy is unclear and contradictory. Certainly, no homework should beassigned that students cannot complete on their own or that they cannot do without expensive equipment. Butif the district is essentially giving a pass to students who do not do their homework because of complicatedfamily lives,it is going riskily close to the implication that standards need to be lowered for poor children. District administrators say that homework will still be a part of schooling;teachers are allowed to assignas much of it as they want. But with homework counting for no more than 10% of their grades, students caneasily skip half their homework and see very little difference on their report cards. Some students might dowell on state tests without completing their homework, but what about the students who performed well on thetests and did their homework? It is quite possible that the homework helped.Yet rather than empoweringteachers to find what works best for their students, the policy imposes a flat, across-the-board rule. At the same time, the policy addresses none of the truly thorny questions about homework. If the districtfinds homework to be unimportant to its students' academic achievement, it should move to reduce oreliminate the assignments, not make them count for almost nothing. Conversely, if homework matters, it shouldaccount for a significant portion of the grade. Meanwhile, this policy does nothing to ensure that the homeworkstudents receive is meaningful or appropriate to their age and the subject, or that teachers are not assigningmore than they are willing to review and correct. The homework rules should be put on hold while the school board, which is responsible for settingeducational policy, looks into the matter and conducts public hearings. It is not too late for L.A.Unified to dohomework right. It is implied in Paragraph 1 that nowadays homework_______. A．is receiving more criticism B．is no longer an educational ritual C．is not required for advanced courses D．is gaining more preferences

Passage TwoQuestions 57 to 61 are based on the following passage. While still catching up to men in some spheres of modem life, women appear to be way ahead in at least one undesirable category. "Women are particularly susceptible to developing depression and anxiety disorders in response to stress compared to men," according to Dr. Yehuda, chief psychiatrist at New York’s Veteran’s Administration Hospital. Studies of both animals and humans have shown that sex hormones somehow affect the stress response, causing females under stress to produce more of the trigger chemicals than do males under the same conditions. In several of the studies, when stressed-out female rats had their ovaries (the female reproductive organs) removed, their chemical responses became equal to those of the males. Adding to a woman’s increased dose of stress chemicals, are her increased "opportunities" for stress. "It’s not necessarily that women don’t cope as well. It’s just that they have so much more to cope with," says Dr. Yehuda. "Their capacity for tolerating stress may even be greater than men’s," she observes. "It’s just that they’re dealing with so many more things that they become worn out from it more visibly and sooner." Dr. Yehuda notes another difference between the sexes. "I think that the kinds of things that women are exposed to tend to be in more of a chronic or repeated nature. Men go to war and are exposed to combat stress. Men are exposed to more acts of random physical violence. The kinds of interpersonal violence that Women are exposed to tend to be in domestic situations, by, unfortunately, parents or other family members, and they tend not to be one-shot deals. The wear-and-tear that comes from these longer relationships can be quite devastating." Adeline Alvarez married at 18 and gave birth to a son, but was determined to finish college. "I struggled a lot to get the college degree. I was living in so much frustration that that was my escape, to go to school, and get ahead and do better." Later, her marriage ended and she became a single mother. "It’s the hardest thing to take care of a teenager, have a job, pay the rent, pay the car payment, and pay the debt. I lived from paycheck to paycheck." Not everyone experiences the kinds of severe chronic stresses, Alvarez describes. But most women today are coping with a lot of obligations, with few breaks, and feeling the strain. Alvarez’s experience demonstrates the importance of finding ways to diffuse stress before it threatens your health and your ability to function.What does Alvarez mean by "I lived from paycheck to paycheck" (Lines 5-6, Para. 5) A．She cared about nothing but making money.B．Her salary barely covered her household expenses.C．She got paychecks from different jobs.D．She paid practically everything by check.
