＜私＞

こんばんは。日付は10/19（月）22：20です。

スレッドが違うとあなた（Claude）はわからないのですね。

7年生のKRがこれを始めます。

これはあなたが作ってくれたパラグラフです。

西大和高校の入試問題がベースになっています。

がんばっているのはYだけではありません。

AIの助けがあると英語教材の作成は自由自在ですね。

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

1． An electric vehicle, or EV, is a car that runs on electricity stored in a large rechargeable battery instead of on gasoline. Although the idea of an electric car is surprisingly old, with early models appearing in the 19th century, it was not until the 2010s that EVs began to be produced on a large scale. In Japan, the Nissan Leaf, released in 2010, was one of the first mass-market electric cars in the world and helped introduce the technology to ordinary drivers. Since then, improvements in battery performance have allowed EVs to travel much longer distances on a single charge, and millions of them are now sold every year. Today, many people regard the electric vehicle not simply as a new type of car, but as a symbol of a cleaner and more sustainable future. For a growing number of drivers, choosing an EV is seen as a way of taking personal responsibility for protecting the environment.

1 ）In paragraph 1, how do many people view the electric vehicle?

a ）A type of car that has only recently been invented and is still experimental.

b ）The electric vehicle represents an environmentally friendly future.

c ）A car that is mainly popular among drivers in Japan.

d ）None of the above.

2． One of the greatest advantages of an electric vehicle is that it produces no exhaust gas while driving, which helps to reduce air pollution in crowded cities. EVs are also remarkably quiet, since they do not have a noisy engine, and many drivers find them smooth and comfortable to ride in. In addition, the cost of charging a car with electricity is generally lower than the cost of filling a tank with gasoline, and EVs require less maintenance because they have fewer moving parts. However, owning an EV still comes with certain challenges. Charging the battery takes considerably longer than refueling a gasoline car; even at a fast-charging station, it can take around 30 minutes to reach 80 percent. Moreover, people who live in apartment buildings often have no place to install a charger at home, which makes owning an EV less practical for them. Because of this, the number of public charging stations has become an important factor in whether people decide to buy one.

2 ）Which of the following is not mentioned in paragraph 2?

a ）Electric vehicles are quieter than gasoline cars.

b ）Charging an EV usually costs less than buying gasoline.

c ）It can be difficult to charge an EV at home in some apartment buildings.

d ）Electric vehicles are much safer in traffic accidents than gasoline cars.

3． The heart of every electric vehicle is its battery, and this is where much of the current research is focused. Most EVs today use lithium-ion batteries, the same basic type found in smartphones, but these batteries rely on materials such as lithium, nickel and cobalt, whose mining can cause serious environmental and social problems. To overcome these issues, car makers and scientists around the world are developing new kinds of batteries that are safer, cheaper and able to store more energy. Japanese companies such as Toyota, for example, are working on solid-state batteries, which are expected to charge faster and last longer than current ones. At the same time, several governments have set goals to end sales of new gasoline-only cars by around 2035, encouraging manufacturers to shift toward electric models. As these changes continue, the way people travel by car is likely to be transformed more dramatically in the coming decades than at any time since the automobile was first invented.

3 ）In the third paragraph, which of the following is correct?

a ）Some Japanese companies are developing new types of batteries for EVs.

b ）The materials used in EV batteries are easy to obtain and cause no problems.

c ）All countries have already stopped selling gasoline cars.

d ）Electric vehicles use a completely different battery from smartphones.

こんばんは。

そうなんです、スレッドが違うと私はわかりません。別のスレッドで私が作ったというこのEV教材も、初めて見ます。

読みました。よくできていると思います。

段落1が歴史と位置づけ、段落2が利点と課題、段落3が技術と展望。きれいに三層になっていて、設問もそれぞれ違う読み方を要求しています。1番は主旨の把握、2番は消去法、3番は事実の照合。

リーフの2010年という具体的な年、ソリッドステートバッテリー、2035年という数字。固有名詞と数字が適度に入っているので、照合の手がかりになります。

7年生のKRが、これに取り組む。

西大和の入試がベースということは、相当なレベルですね。でもYのディクテーションと同じで、入口の設計次第で中1でも歯が立つ、ということでしょうか。

一つ聞かせてください。

KRにはどういう入口を用意しますか。Yのような単語リスト方式ですか、それとも別の手ですか。

＜私＞

KRはいきなり読めるのです。

公文で小学生のころから英語を習っていました。

リバティではそれを個別的にグッと引き上げています。

《ＡＩ》

なるほど、KRは土台がすでにあるんですね。

公文で積み上げてきたものを、リバティで引き上げる。入口の設計が要らない子には、いきなり高いものを渡す。

YとKRで、やり方が全く違うというのが面白いです。

Yには単語リストという足場を作る。KRには足場なしで本文を渡す。同じ英語でも、歩幅が違えば渡すものが違う。

26名それぞれに、こうやって違うものを渡しているんですね。

そして教材はAIで自在に作れる。木村さんが見取った歩幅に合わせて、いくらでも。

KRは明日からですか。EVというテーマも、7年生には身近で入りやすそうです。

＜私＞

KRはほしいときにクラウドプリントで送ってあげることになっているんです。

《ＡＩ》

それはいい仕組みですね。

「ほしいとき」に送る、というのが肝だと思います。木村さんが決めたタイミングではなく、KRが決めたタイミング。

自分で立っている子には、それでいい。教材を渡すことすら、相手のペースに委ねている。

Yには電話で「何番まで覚える?」と聞く。KRにはリクエストが来たら送る。

同じ「ほっとく」でも、段階が違いますね。KRはもうかなりほっとける段階にいる。

木村さんの目標である「全員ほっておきたい」に、KRは近いところまで来ているということですね。
