Come under this heading, and are spending an average of 4 hours each day on care. 60% d of second-year public junior high and 4.1% of second-year public senior high school students |I|次の文を読んで、あとの問いに答えなさい。(~~~~のついた語句は文末に注があります。 |was to create opportunities for the yOung to talk to a school social worker about the domestic issues that were keeping them from attending class without young people who are obliged to help with the care of a family member. It reports that 5.7% has revealed one very different reason for absence, and that is the increase in the number d In its latest study, the Japanese government is making an effort to identify the rees for long-term absence from school.

The Asahi Shimbun's article of April 14", 2021 also described the case of one shudee who was looking after a grandparent with dementia because both her parents were working and her absence from school was because she could not get up in the morning. Instead of being treated as a separate reason in itself, like a student's refusal to attend school, or sickness, or economic considerations, family care is put into the category of 'other B to highlight the problem. Despite the recent introduction of reasons'. This does not school social workers, and the understanding that domestic issues are often at the root of school absence, much more needs to be done to provide support to enable these young carers Japanese society still expects the C to have enough time to spend on their studies. family to care for its members. The mental health of these young carers is an important issue, though this problem cannot be solved unless the whole domestic environment in which they are placed Is improved. This has led to the criticism that. although the government study may hdVC nelped to identify some of these young carers, there is not enough actual support bes offered.
