2. The speaker's intention
In this scenario, the choice of expression is dictated not by the chair type, but by the speaker's purpose, or what the speaker has in mind. The usage of the prepositions (on and in) is one clear distinction between these phrases ("sit on the chair" and "sit in the chair"), and these prepositions are not merely there for fancy reasons. When you advise someone to "sit in the chair," you are almost always asking him to make himself comfortable in the chair, which is not the case when you say "sit on." That is why you sit on a bench, stool, or dining chair rather than an armchair.
LLabel It: This is a good option for beginners of all ages who need a refresher on fundamental language. This task should be doable as long as the students can recognize initial letter sounds. To help my children learn the names of items in the classroom, I label everything with an index card with the item's name on it. Then I have them repeat what I'm saying while pointing to the object. The next day, I take the cards and go through them one at a time, placing them on the appropriate object with you. I let them identify everything they could on their own the third day. I'll keep doing this for a few days. When students are able to name most of the things independently, I surprise them by labeling them erroneously. Then they must clean up the shambles. You may adapt this to any noun-based vocabulary list (for example, sorts of foods, bodily parts, components of a room in a home, animals, and so on) that you can photograph. Your website includes fantastic flashcards and images that can be printed and utilized for this purpose. (Sent in by KMMP)
Why do I have back ache when I sit? Lower back pain is often caused by poor sitting posture, since a slouched or slumped over sat position exerts pressure on the discs. A underlying medical problem, such as sciatica, herniated disc, muscular strain, or degenerative disc disease, might aggravate the discomfort. Upper back discomfort may be caused by forward craning when staring at a computer screen or phone display. How many calories do you burn while you sit? The number of calories expended when sitting varies substantially depending on variables such as weight, exercise level, age, gender, and health condition. Sitting is a low-calorie-burning activity, but the more active you are, the more calories you will burn when sat. A 150-pound individual burns 68 calories per hour sitting quietly, 102 calories performing light labor, and 170 calories doing moderate effort.
