Adult Basic Education(ABE)and GED Preparation

Task(任务)

The Adult Basic Education Department serves a huge population of learners. Our task is to teach basic skills and help learners to get more knowledge to function effectively as a family member, citizen, worker, and lifelong learner in a changing world.

Description(描述)

ABE is a non-credit program of self-improvement designed to improve basic skills for students who are of different educational level. Development of reading, writing, and math skills are paid special attention to, as well as life skills, employability, and technology. Students without a high school diploma(文凭)also have the opportunity to prepare for the GED exams in the five subject areas writing, social studies, science, literature, and math.

Prerequisites(条件)

ABE classes are open to anyone 18 or over who desires to improve basic reading, writing, and math skills at the pre-college level. Students who are 16 or 17 must first obtain an official release( 证书)from high school before attending class.

To be accepted, students must attend an Educational Planning Session. During the Educational Planning Session students will be given an overview of the ABE programs as well as PCC policies, fees, etc. Students will also have their reading, writing, and math abilities assessed(评估)during the Educational Planning Session The results of their assessment will help the teachers develop individual programs of study for students to guide them toward their personal goals. Students needing special help must get in touch with the Office for Students with Disabilities(503-977-4341)at least two weeks before the session is held.

Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.

The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.

“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.

“Within the heart there are millions of cells(细胞)that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process. ”

What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.

“This gender difference might just explain why women live longer than men,” said Goldspink.

They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease.

The team has yet to find why ageing takes a greater loss on the male heart, said Goldspink.

The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.
