問1

問題次の文章を読み、下の問いに対する答えとして最も適当なものを、下の1~4のうちから1つ選べ。

Satellites are very closely tied to our daily lives. The best example of this is weather observation satellites. During a weather forecast on television, you can see images of cloud patterns over Japan from the Himawari satellite.
In fact, the table blow shows the satellite in use in mid-2007 was the sixth in the Himawari series, which stretches back to 1997. The six Himawari satellites have each had different characteristics.

Data correct as of June, 2007

Most of the satellites in the Himawari series have had ( 問1 ) of around six years. However, Himawari 2’s operations were taken over by Himawari 3 after less than three years, and the lifetime of Himawari 5 was extended after there was trouble in launching a new rocket. In 2003, HImawari 5 could no longer be used, which meant there was no functional Himawari satellite in space. As a result, information from an American satellite was used for two years. In 2005, Himawari 6 was launched and the supply of weather photos from Japanese satellites resumed.
Although most of the satellites in this series have been a similar size and weight, Himawari 6 is much bigger than the previous ones as it has air-traffic control as well as weather observation functions. It is the first of a new generation of multi-function satellites.

問1
From the information in the passage, and table, which of the following is the most appropriate for the blank? ( 問1 )

1. a launch date
2. an operating lifetime
3. an out-of-service period
4. a repair time

【解説】

( 問1 )
空所に入るのに最も適当なものはどれか? という問題。まずは ( 問1 ) の含まれている英文をみましょう。

Most of the satellites in Himawari series have had ( 問1 ) of around six years.
「ほとんどのヒマワリシリーズの人工衛星はおよそ6年の ( 問1 ) を持っている」

とありますね。しかし、これと表だけで解答にはたどり着きません。

その次の文の文頭の However という英単語に注目しましょう。however は逆接の接続詞で、その前後には逆の意味がきます。そしてその後ろのほうが重要なことが書いてあります。

However, Himawari 2’s operations were taken over by Himawari 3 after less than three years,
「しかしながら、『ヒマワリ2』の operations は3年も満たずに『ヒマワリ3』へ引き継がれた」

これだけでも正解は選べそうな気もしますが、続きに and があるので続きを確認しておきましょう。

and the lifetime of Himawari 5 was extended after there was trouble in launching a new rocket.
「そして『ヒマワリ5』の lifetime は新しいロケットの打ち上げ時のトラブルで延ばされた。」

選択肢はこうなっています。
1. a launch date / 打ち上げ日
2. an operating lifetime / 活動存続期間
3. an out-of-service period / 使用していない期間
4. a repair time / 修理時間

普通は6年なのに、3年しか持たなかったんですね。ということは、正解は「2. an operating lifetime / 活動存続期間」です。

【正解】2

Data
correct as of June, 2007

Most of the satellites in the Himawari series have had ( 問1 ) of around six years. However, Himawari 2’s operations were taken over by Himawari 3 after less than three years, and the lifetime of Himawari 5 was extended after there was trouble in launching a new rocket. In 2003, HImawari 5 could no longer be used, which meant there was no functional Himawari satellite in space. As a result, information from an American satellite was used for two years. In 2005, Himawari 6 was launched and the supply of weather photos from Japanese satellites resumed.
Although most of the satellites in this series have been a similar size and weight, Himawari 6 is much bigger than the previous ones as it has air-traffic control as well as weather observation functions. It is the first of a new generation of multi-function satellites.

問2
Which of the following is true about Himawari 6?

1. It is bigger than the others because it has additional functions.
2. It is just five times the weight of Himawari 1.
3. It was taken into space by a Delta rocket from a launch site in Florida.
4. It went into service immediately after its launch.

【解説】

Which of the following is true about Himawari 6?
「『ヒマワリ6』に関して正しいのはどの文か?」

選択肢はこうなっています。

1. It is bigger than the others because it has additional functions.
追加の機能があるので他のものより大きい。

確かに他のヒマワリより大きいことが表からわかりますが、その理由は書いていませんね。とりあえず保留にしておきましょう。

2. It is just five times the weight of Himawari 1.
『ヒマワリ1』のちょうど5倍の重さ。

表より『ヒマワリ1』が325kg、『ヒマワリ6』が1250kgなのでおよそ4倍。5倍ではないので、選択肢2.は不正解ですね。

3. It was taken into space by a Delta rocket from a launch site in Florida.
フロリダの打ち上げ基地からデルタロケットによって宇宙へ送られた。

表より『ヒマワリ1』の内容です。したがって不正解。

4. It went into service immediately after its launch.
打ち上げの後、すぐに使用された。

表より2005年の2月に打ち上げられ、2005年の6月にサービスを開始している。ということは、間に4か月あり、すぐに使用されたという選択肢4.は不正解。

この時点で消去法により正解は1.であるとわかりますが、最終段落に

Himawari 6 is much bigger than the previous ones as it has air-traffic control as well as weather observation functions.
ひまわり6は、航空管制や気象観測機能を備えているため、従来のものよりもはるかに大きくなっています。

とあるので間違いないことが確かめられます。

【正解】1

問3

問題次の文章を読み、下の問いに対する答えとして最も適当なものを、下の1~4のうちから1つ選べ。

Most of the satellites in the Himawari series have had ( 問1 ) of around six years.

In 2005, Himawari 6 was launched and the supply of weather photos from Japanese satellites resumed.
Although most of the satellites in this series have been a similar size and weight, Himawari 6 is much bigger than the previous ones as it has air-traffic control as well as weather observation functions. It is the first of a new generation of multi-function satellites.

問3
How did Japan get satellite weather data after 2003?

1. An American satellite provided Japan with data.
2. Functional Himawari satellites collected data.
3. Himawari 5 was repaired and reused.
4. Himawari 6 was launched immediately.

【解説】

How did Japan get satellite weather data after 2003?
「2003年の後、日本はどのように衛星の天候のデータを取っていたのか?」

表を見ると『ヒマワリ5』の活動期間が1995~2003で、『ヒマワリ6』が2005~となっているので、その間の話であることがわかりますね。

本文に In 2003, というものがあるので、この周辺にこの問題のヒントがあることがわかります。

In 2003, HImawari 5 could no longer be used, which meant there was no functional Himawari satellite in space. As a result, information from an American satellite was used for two years.
「2003年に、『ヒマワリ5』はもはや使えなくなった。それは宇宙に機能しているヒマワリがないという意味だった。結果としてアメリカの人工衛星からの情報を2年間使った」

選択肢はこうなっています。

1. An American satellite provided Japan with data.
アメリカの人工衛星が日本にデータを供給した。
2. Functional Himawari satellites collected data.
機能しているヒマワリがデータを集めた。
3. Himawari 5 was repaired and reused.
『ヒマワリ5』は修理されて再び使われた。
4. Himawari 6 was launched immediately.
『ヒマワリ6』がすぐに打ち上げられた。

ということで正解は1。

【正解】1

第4問Aは問題文を本文より先に読み、何について聞かれているかを頭に入れておいた上で、本文からその情報を探し出すという感覚で解くとよいですね。
