Everyone knows that without oxygen, people will die within minutes.
However, what most people do not know is that modern people, especially those who have lived in densely populated large cities for a long time and are facing heavy pressures, often fall into a state that is medically called "chronic hypoxia of the human body".
The main symptoms are: dizziness, headache, tinnitus, dizziness, weakness of the limbs; Or nausea, vomiting, palpitation, shortness of breath, shortness of breath, shortness of breath, rapid heartbeat and weakness.
The best solution is this: the family often goes to the lush countryside to live for a while.
For the vast majority of parents, they hope that their children can be admitted to the ideal university in the future and become a talent useful to society.
We have designed a set of ecological intelligent health care and learning system for everyone to experience rural life while combining specific agricultural production practices, using network technology and artificial intelligence technology to learn foreign languages and courses such as mathematics, physics, chemistry, geography, biology, programming and so on.

Below, we focus on "Mineral Nutrients".
Friends who read my articles a lot are sure to know: English, French, German, Italian, Spanish -al is derived from the Latin adjective suffix -alis.
Mineral['mɪnərəl]n. mineral, soda, inorganic adj. Mineral, mineral; inorganic
Disassembly: miner+al.
[English] miner[ˈmainə]n.1. Miner 2. Mine Sapper 3. Miner 4. Insects that inhabit leaves in the larval stage
拆解:min(e)+er。
Mine 1[maɪn]adj. It's mine
Mine 2[maɪn]n.1. Mine 2. Abundant resources; treasury
A good encyclopedia is a mine of information.
A good encyclopedia is a treasure trove of knowledge.
3. Mines 4. dynamite

Please ask parents and friends to know about the etymology:
From Middle English, from Old French mine, from Late Latin mina, from Gaulish (compare to Welsh mwyn, Irish mianach (“ore”)), from Proto-Celtic *mēnis (“ore, metal”).
We can roughly understand that the word mine in the English table "mine" is derived from the Latin mina through Old French.
Obviously, Old French changed the Latin word -a to -e.
[French] mine[min] n.f. face, look, expression n.f. [military] (old) tunnel f. mine, mine; deposit; mine
【拉丁语】mina：mina, minae n. f. mine (exploding); (Cal);
We can roughly understand that the English word mineral is composed of min- and suffixes -er, -al.
Nutrient['nuːtrɪənt /'nju-]n. nutrients, nourishing adj. Nutritious, nourishing
Disassembly: nu+tri+ent.
【词源】Borrowed from Latin nūtriēns, present participle of nūtriō (“I suckle, nourish, foster”).
【Latin】nutrio (classical pronunciation /ˈnuː.tri.oː/, metropolis pronunciation /ˈnu.tri.o/):nutrio, nutrire, nutrivi, nutritus v. suckle. breast feed; nourish/feed/fuel, supply, build up; preserve, look after;
拆解:no+tri+o。
Please remember that nu- in Latin, Italian, Spanish, german nu- and "nunu" in Chinese are basically the same.
The French nu corresponds to Hanyu Pinyin and the German nuu.
【词源】From Proto-Italic *snoutrjō, from Proto-Indo-European *snew-tr-ih₂ (“female nurser”), maybe from *(s)neh₂- (“to flow”). Cognate with Sanskrit प्रस्नौति (prasnauti, “to drip, to release liquids”), प्रस्नुत (prasnuta, “releasing mother's milk”). Appurtenance of Ancient Greek νάω (náō, “to flow, to stream”，国际音标/nǎː.ɔː（古）/ → /ˈna.o（中古）/ → /ˈna.o（现代）/) is difficult and requires additional assumptions.
At least 6,000 years ago, there was a group of people who uttered *(s)neh₂ - such a sound table meaning "flow, swim".
Later, the preceding *s fell off, changing to nau- or nu- in Sanskrit, nu- in Latin, and να-(na) in Greek.
Please understand: the Greek να- corresponds to the Latin na- and the Pronunciation of "Na na" in Chinese is basically the same.
In PIE (Proto-Indo-European), *(s)neh₂- table "flow, swim".
Ancient Greek Ναϊάς (Naïás), Νηρεύς (Nēreús), Latin nō, Sanskrit's स्नौति (snauti, "to flow; drip") is all derived from this.
At this point, we have understood that the focus of memorizing nutri-nu-, while -tri is the auxiliary part.
Nourish[ˈnʌriʃ]vt.1. Fertilize with; Nourish 2. Parenting; Parenting 3. Supply; Fueling 4. Embrace (hope, resentment, etc.)
Nourish feelings of hatred are in the heart
Milk nourishes a baby.
Dismantling: nour+ish.
Here -ish is the verb suffix.
【词源】From Middle English norischen, from Old French nouriss-, stem of one of the conjugated forms of norrir, from Latin nutriō (“to suckle, feed, foster, nourish, cherish, preserve, support”).
We can roughly understand: Old French changed the Latin nutr- to nour-. That is, change nu- to nou-.
Please remember the main points of parents and friends: in English, ou derived from the old French word is usually pronounced [ʌ], please be familiar with the English words double (double), trouble (trouble), couple (spouse), where ou are read [ʌ].
The English word derived from modern French is generally pronounced ou [u:], which basically retains the pronunciation of modern French. Such as group (group), soup (soup), rouge (lipstick), route (distance), coup (coup), where ou are read [u:].
It is highly recommended that you memorize doubles in English and French at the same time.
[English] double[ˈdʌbl]adj.1. twice; Doubling the 2. Double; Double 3. 4. for both. (meaning) pun intended; Ambiguous 5. Inconsistencies in appearance; Duplicitous; Insidious 6. One person plays two roles of 7. Folded in half (paper) 8. 【Implant】Heavy petal 9. [Tone] low octave
Disassembly: dou+ble.
[French] double[dubl]a. double, double; double, double [turn] two-sided, two-sided n.m. double copy, copy; replica, copy
Disassembly: dou+ble.
【词源】From Old French doble, from Latin duplus.
Key memory: French dou - equal to the Latin du - table "two".
【Latin】duplus (International Phonetic Alphabet/ˈdu.plus/):d uplus, dupla, duplum adj. twice as much, double;
拆解:du+plus。
【词源】From Proto-Italic *dwiplos, from duo + plus. Cf. Ancient Greek διπλόος (diplóos, “double”), from δι- (di-), from δύο (dúo, “two”), + -πλόος (-plóos, “-fold”), and Proto-Germanic *twīflaz (“doubt”).
The Greek δύο (dúo, "two") is derived from the Proto-Greek language *dúwō and from PIE (Proto-Indo-European)*dwóh₁.
Homologous with Sanskrit द्व (dvá), Old Armenian երկու (erku), And Old English twā (English two).
Tell your child that the word "two" in the English table "two" is the root of the word, corresponding to the Latin du-, which in French sometimes changes to dou-.
So, we just need to focus on memorizing the English words two (two), twelve (twelve), twenty (twenty), twice (two), twine (twins), between (in between).
At the same time, you can also learn the double (double) derived from French, and the English word dualism (dualism), duet (duet) derived from Latin.
In addition, you can easily grasp many scientific terms derived from Latin and Greek in English, French, German, Italian, and Spanish on the basis of a general understanding of bi-, di-table "two".
For example, the English dioxide, dilemma, divide, divorce, diminish, diphosphate.
Earlier, we have introduced it many times: -ma is derived from the noun suffix of the Greek table "result", while -tic is the adjective suffix.
If you understand the di-table "two", -ma is the noun suffix of the table "result", and then remember dilemma's focus is only to be roughly familiar with lem-.
Dilemma [daɪˈlemə]n. dilemma; Dilemma; Dilemma
拆解:di+lem+ma。
【词源】First attested 1523, from Late Latin dilemma, from Ancient Greek δίλημμα (dílēmma, “ambiguous proposition”), from δι- (di-, “having two of”) + λῆμμα (lêmma, “premise, proposition”).
Please familiarize yourself with the following example sentence:
I am in a dilemma whether to do maths or English.
I was torn between doing math or writing English.
The doctor was in a dilemma as to whether to tell the patient the truth about his condition or not.
"The doctor was in a dilemma and didn't know whether to tell him the patient's true condition."
The ideas of how to help their company get out of dilemma occupied the proscenium of his mind.
His first thought was how to help their company out of trouble.
I believe that knowing lem - and then memorizing blem - is certainly not a problem, so it is easy to master problem.
Problem[prɑbləm /'prɒ-]n. problem, puzzle adj. Problematic, difficult to deal with
拆解:pro+ble+m。
[French] problème[prɔblɛm]m. question
Disassembly: pro+ble+ma.
[German] Problem (Pʁoˈbleːm/) [das] question. Puzzles. Troublesome. Difficulty.
拆解:pro+ble+m。
【词源】From Middle English probleme, from Middle French probleme, from Latin problema, from Ancient Greek πρόβλημα (próblēma, “anything thrown forward, hindrance, obstacle, anything projecting, a headland, promontory”), from προβάλλω (probállō, “to throw or lay something in front of someone, to put forward”), from προ- (pro-, “in front of”) + βάλλω (bállō, “to throw, to cast, to hurl”).
