Nanotechnology is around us PPT, the third part: text interpretation and reading

The first natural section is about understanding nanometers and micrometers.

Nanometer: Nanometer (nm), translated as nanometer, is a unit of measurement of length. The international unit symbol is nm.

Micron length unit, symbol: um, u is pronounced "miu". 1 micron is equivalent to one thousandth of a millimeter.

Read the second natural paragraph and think about it: What is this paragraph mainly about?

Nano is a small unit of measurement of length and what is nanotechnology.

2. Read the sentences and feel the explanation method.

A nanometer is a very, very small unit of length measurement, very, very small.

A nanometer is a very small unit of length measurement, 1 nanometer is equal to one billionth of a meter

Read the third natural paragraph and see what examples the author gives to illustrate that nanotechnology is all around us.

Nano raincoat umbrella is a combination of umbrella and raincoat. Nano umbrellas are available in three-fold umbrellas and straight umbrellas (simply put, there are two options for folding umbrellas: long and short). Nano raincoats can be transformed from nano umbrellas. Nano raincoats are different from ordinary raincoats because they can guarantee that they will never get wet from head to toe. Because of the nanomaterial, the umbrella can be tossed and dried. After the umbrella is transformed into a raincoat, the raincoat can be completely dried by just wearing it.
