Duolingoの穴埋め問題は対策があまりありません。
別ノートで読解穴埋め問題は解説しました（以下参照）。
https://www.alpha-notes.com/notes/duolingo125/a47b0a7bfcbec4c12050
これらも参照したうえで、後は問題演習量をこなしましょう。
以下の空欄の数字分のスペルを埋めて、全体が意味の通じる文章になるようにしましょう。
例）He beh( 4 ) badly, so his mother go( 1 ) angry.
=> He behaved badly, so his mother got angry.
適宜問題をこれからあげて行きますので
挑戦=>解答確認=>解説 の順で学習してみてください。難易度は1～10の中から主観で選んでいます。
（個人的に模擬試験で一番難しいと思った穴埋め問題のレベルを8にして調整しています）
今回は難問回なので、1問3分という制限時間をフルに使って考える事。難しいが根拠がないわけでは無い（本番の問題の方には理不尽な難しさはたまにある）。
問題9)
Every animal or plant on Earth has adaptations, o( 1 ) specific characteristics, th( 2 ) help ( 2 ) stay alive in its habitats. Examples of adaptations are fur, feather and fat to help animals k( 3 ) warm in cold places, long legs to help animals escape from their predators or camo( 6 ) to help animals hide from their predators.
Ov( 2 ) time, animals and plants change and evo( 3 ) because off( 6 ) have slightly different characteristics to their parents. Living things b( 3 ) with adaptations that make their lives eas( 3 ) in specific habitats ( 3 ) more likely to survive; the process of advantageous adaptations be( 3 ) passed onto future generations is known ( 2 ) natural selection.
問題 10)
Bo( 2 ) deduction and induction help us navigate real-world problems, su( 2 ) as who committed a crime, the most likely ca( 3 ) of an accident, or how many planets might cont( 3 ) life in the Milky Way galaxy. But wh( 3 ) they're both practical tools for pra( 6 ) problems, they approach problem-solving in op( 6 ) ways. Inductive reasoning is the act of using spe( 5 ) scenarios and making gener( 6 ) conclusions, or moves from specific observations to broad( 2 ) generalizations and theories. Also referred ( 2 ) as "cause-and-effect reasoning," inductive reasoning can be thought of as a "bo( 4 ) up" approach. D( 8 ) reasoning works the other way, go( 3 ) from the general to the more specific. We might begin with thinking u( 1 ) a theory about our topic of interest. We then narrow that down into more specific hypo( 6 ) that we can test. This leads us to red( 3 ) our theories down into certain conclusions.
