Below aresample expository essays aboutthelightning phenomenon for 8th-grade students in Vietnam.

đá bóng trực tiếp explanation will help students better understand đá bóng trực tiếp essence of đá bóng trực tiếp lightning phenomenon – a natural phenomenon that is both familiar and mysterious.

Sample No. 1:

One of đá bóng trực tiếp few natural phenomena that we often encounter is lightning.

Currently, there is a branch of science dedicated to đá bóng trực tiếp study of lightning around đá bóng trực tiếp world, known as Brontology. They have provided detailed explanations of this phenomenon. Lightning (also simply called thunder) is a type of sound caused by lightning strikes. They are đá bóng trực tiếp product of đá bóng trực tiếp sudden increase in pressure and temperature from a lightning bolt, causing instantaneous expansion in đá bóng trực tiếp air. This expansion creates a sound shock wave - known as thunder. Depending on đá bóng trực tiếp distance and characteristics of đá bóng trực tiếp lightning strikes, we can hear different types of thunder. Generally, there are two types, one is a sudden loud bang, and đá bóng trực tiếp other is a prolonged series of sounds. With its characteristic loud sound, thunder can pierce a person's eardrums, leading to impaired hearing or temporary deafness.

Lightning usually appears after we see đá bóng trực tiếp flash of lightning across đá bóng trực tiếp sky, often accompanying rain. Hence, it can be easily seen frequently without having to chase after it. They do not cause significant damage to people and property, so there are no activities aimed at prevention or deterrence. To this day, lightning still appears naturally alongside human life.

SampleNo. 2:

Lightning is a natural phenomenon, often occurring before, during, and even after rain.

đá bóng trực tiếp cause of đá bóng trực tiếp lightning phenomenon is when two clouds with opposite charges come close together, đá bóng trực tiếp electrical potential between them can reach millions of volts. Between đá bóng trực tiếp two clouds, there is an electrical spark discharge, and we see a lightning bolt. A few seconds later, we hear đá bóng trực tiếp explosion, which is thunder (as đá bóng trực tiếp speed of light is faster than đá bóng trực tiếp speed of sound, we see đá bóng trực tiếp lightning bolt first). When a storm cloud with electrical charge approaches đá bóng trực tiếp ground in open areas and encounters a tall object like trees or a person holding a spade, there will be an electrical discharge phenomenon between đá bóng trực tiếp cloud and đá bóng trực tiếp ground. That is đá bóng trực tiếp lightning phenomenon. During lightning discharge in đá bóng trực tiếp atmosphere, a lightning bolt can travel at a speed of 36,000 km/h. Lightning is đá bóng trực tiếp movement of ions, but đá bóng trực tiếp image of lightning is created by glowing plasma current, so it can be seen before hearing đá bóng trực tiếp sound because sound travels at a speed of only 1,230 km/h under normal air conditions, while light travels at 299,792,458 m/s. Lightning can reach temperatures of 30,000°C, 20 times hotter than đá bóng trực tiếp temperature needed to turn silica sand into glass.

Therefore, we need to be fully equipped with knowledge about lightning to avoid unwanted dangers.

SampleNo. 3:

When đá bóng trực tiếp sky turns to rain, all things will become fresh and full of life, but when it rains too heavily, extremely dangerous phenomena like lightning will appear.

Lightning, also known by đá bóng trực tiếp shorter name thunder, is đá bóng trực tiếp sound created by lightning strikes. We might wonder what causes đá bóng trực tiếp formation of lightning; it is due to a sudden increase in air pressure and temperature, causing instantaneous expansion in đá bóng trực tiếp air, creating a sound shock wave.

Lightning is extremely dangerous as it can cause electric shock or death if someone is struck. However, lightning is not entirely harmful; it also brings some benefits like creating đá bóng trực tiếp ozone layer for đá bóng trực tiếp atmosphere, improving soil, and enhancing đá bóng trực tiếp growth potential of plants by creating nitrogen for them to develop.

There are many ways to avoid lightning such as avoiding going out on days with heavy rain and lightning, but if it is necessary to go out, avoid standing under large trees or using a mobile phone. All natural phenomena are incredibly special and have their own beauty; we should always cherish and love đá bóng trực tiếp nature around us.

Lightning is an incredibly special and interesting natural phenomenon, helping us understand đá bóng trực tiếp beauty of nature and surroundings; however, it is also quite dangerous, so each person needs to be fully equipped with knowledge for prevention.

How many regular assessment testswillan 8th-grade student in Vietnam take in Literature?

Under Clause 2 Article 6 ofCircular 22/2021/TT-BGDDTregulating regular assessment for secondary school students in Vietnam:

Regular assessment

...

2.In each subject, each student shall be examined and assessed multiple times where several examinations and assessment satisfactory to teaching progress as per education plans of specialized departments are selected and đá bóng trực tiếp results thereof are recorded in student monitor and assessment record (by classes) in order to assess learning results of a subject according to Clause 1 Article 9 hereof as follows:

a) For subjects where assessment is conducted via feedback (does not include learning topics): choose twice each semester.

b) For subjects where assessment is conducted via both feedback and scores (does not include learning topics), choose regular assessment scores (hereinafter referred to as “DDGtx”) in each semester as follows:

-Subjects that have 35 periods/school year: 2 DDGtx.

-Subjects that have from more than 35 periods/school year to 70 periods/school year: 3 DDGtx.

-Subjects that have more than 70 periods/school year: 4 DDGtx.

...

At đá bóng trực tiếp same time, under Section 8, đá bóng trực tiếp General Education Program in Literature issued withCircular 32/2018/TT-BGDDT, đá bóng trực tiếp time allocated for 8th-grade Literature is 140 lessons/year.

Therefore, 8th-grade students will take 04 regular assessment testsin Literature.
