Est is third-person singular and sont third-person plural of être. They express “is / are” — a state or description. If a past participle follows, it is a different structure such as the passive, so check the words that follow.

Au 31 octobre, le gazole coûtait en moyenne 2,380 euros le litre, en baisse.

The imparfait describes states, background, habits and actions in progress in the past (il était, elle avait, ils pensaient). Take the nous form of the present, drop -ons, and add -ais / -ais / -ait / -ions / -iez / -aient. If the passé composé gives “the event itself”, the imparfait paints “the situation at the time”.

The passive means “is done” or “is being done”. It is formed with être + past participle, which agrees with the subject in gender and number (la mesure est adoptée / les mesures sont adoptées). The agent is introduced by par (or de). In the news it is common when the event, rather than the actor, is the focus (est prévu / est annoncé / est connu).

Les conditions varient selon les stations : vérifiez avant de faire le plein.

The imperative expresses commands, requests and advice. It has no subject: the sentence starts with the verb (Consultez les informations.). The vous form ends in -ez, nous in -ons (Restons prudents.), and tu in -e for -er verbs (Consulte). It is very common in notices and warnings (Vérifiez, Consultez, Restez informé).

Intermarché s’engage à répercuter la baisse, sans date ni montant précisés.

A pronominal verb is used with a reflexive pronoun (me, te, se, nous, vous) before the verb. It can mean “do to oneself”, “be done” or “do to each other”. In the news, se traduire (to result in), se tenir (to take place), s’agir de (to be a matter of) and se diffuser (to spread) are frequent. The pronoun changes with the subject (il se tient / ils se tiennent / je me souviens).

Normally ne and pas wrap the verb. Before a vowel, ne becomes n’. Check which part of the sentence the negation covers. Ne … plus means “no longer”.

Les conditions varient selon les stations : vérifiez avant de faire le plein.

Selon means “according to”. Put a person or organisation after it as the source. It separates facts the writer checked directly from what another body or report said. Citing a source does not turn a forecast into an accomplished fact.

Les stations concernées, la durée et le prix du jour peuvent différer.

Put a base-form verb after pouvoir. Peut means “can” or “may”; the conditional pourrait gives a more reserved possibility, “might”. It does not necessarily mean implementation is settled.

TotalEnergies affiche depuis le 31 octobre le gazole à 2,15 euros le litre dans ses 705 stations Access, soit 10 centimes sous le plafond de 2,25 euros appliqué dans tout son réseau.

Le 15 octobre means “on 15 October”. Distinguish the le before a date from the le that marks a weekly habit like a weekday. Du is de + le and au is à + le, so decide the meaning from the verb and period expressions around them. Their role depends on the group: a range of dates, the date of a bulletin or another complement.

Coopérative U promet jusqu’à 18 centimes de moins dès le 1er novembre, selon les coûts de transport de chaque station.

Dès means “as early as” or “as soon as”, and à partir de means “from … onwards”. Depuis basically shows a state or period continuing from a point in time. All deal with a start, but they are not used the same way.

franceinfoによると、E.ルクレールは11月1日（日）から、742のガソリンスタンドで軽油を1リットルあたり21サンチーム（0.21ユーロ）値引きします。

As in “LCPによると”, it shows where the information comes from. What that source reported follows. It is used differently from “私にとって”, which gives one’s own opinion.

値下げの対象店舗、期間、現在の価格は店ごとに違う可能性があります。

These forms say something may happen. Even when “possibility” is written, it does not mean it will certainly happen. Check whose forecast it is, plus the time and conditions.

値下げは軽油だけの話で、ガソリンの値下がりを意味するものではありません。

They negate a noun and similar content. “ではありません” is the polite form and “ではない” the plain form. “成立ではありません” shows that it cannot be said to have been concluded.

トタルエナジーは31日から、最も安い「Access」系の705店で軽油を1リットル2.15ユーロにしました。

In “発表しました”, ました makes a verb polite past. The negative is “ませんでした”. Read the actual date together with the date and time in the text.

政府が放出した戦略備蓄の燃料の費用と市場価格の差を、利益を上乗せせずに利用者へ還元する、と同社は説明しています。

The て-form links actions in a series, in order or as a reason. In “確認して、出発する” the relation is judged from the content. In “〜ている” it can show an action in progress or a continuing state.

政府による戦略備蓄の放出を受けた値下げです。

A explains noun B that follows. It is not only possession: the relation can be belonging, target, content and more. In “政府の案” and “年金の税控除”, read the relation from the context.
