Pembahasan

Kata-kata can , could , dan be able to adalah kata-kata yang digunakan untuk mengekspresikan kesanggupan atau kemampuan. Dalam Bahasa Indonesia, kita umumnya menggunakan kata-kata seperti bisa , dapat , atau mampu . C an dan could adalah modal yang memiliki arti yang sama , tetapi berbeda dalam hal tense : can digunakan untuk present tense dan could untuk past tense. Pola penggunaan can/could dalam kalimat positif dan negatif adalah S + can/could (+ not) + V1 (kata not ditambahkan hanya dalam kalimat negatif). Pola penggunaan can/could dalam pertanyaan Wh- dan Yes/No adalah (Wh-) + can/could + S + V1 (kata tanya Wh- hanya ditambahkan pada pertanyaan Wh- ) Contoh penggunaan can/could dalam kalimat: The students could (can) complete the test quickly . The students could (can) not complete the test quickly . We can (could) catch the plane on time . We can (could) not be able to catch the plane on time . Can (could) the students complete the test? Can (could) we catch the plane on time? What can (could) you do in a stressful situation? What can (could) we do in an emergency? Berbeda dengan can/could, be able to bukan modal, meskipun sama-sama mengekspresikan kesanggupan atau kemampuan. Pola penggunaan be able to dalam kalimat positif dan negatif adalah S + to be (+ not) + able to + V1 atau S + modal (+ not) + be able to +V1 (kata not hanya digunakan dalam kalimat negatif). Pola penggunaan be able to dalam pertanyaan Wh- dan Yes/No adalah (Wh-) + be + S + able to + V1 atau (Wh-) + modal + S + be able to + V1 (kata tanya Wh- hanya digunakan dalam pertanyaan Wh- ). Contoh penggunaan be able to dalam kalimat: The students were able to complete the test quickly . The students were not able to complete the test quickly . We may be able to catch the plane on time . We may not be able to catch the plane on time . Were the students able to complete the test? Will we be able to catch the plane on time? What are you able to do in a stressful situation? What must we be able to do in an emergency? Jadi, jawaban yang benar untuk soal di atas adalah: " His handwriting was so bad that I could not read his letter at first ." " His handwriting was so bad that I was not able to read his letter at first. "
