"No, he doesn't see a truck."
Translation:לא, הוא לא רואה משאית.
Agreed, the alphabet should be taught in these "letter" sections letter by letter and vowel by vowel. I had to learn it on a different site but afterwards it made this much easier. I'm not sure if I can get in trouble for posting another language site on here so I'll just say google it for now. I will say this is really fun once you can read it and understand it.
You're allowed to post links on here. In fact, Duolingo has two official courses on Memrise to supplement this course. Hebrew Alef-Bet teaches the letters, and Hebrew Duolingo has all the vocab from this course, in order, with audio for every word! It's been extremely helpful.
I've also found these helpful: This memrise course will teach you where all the Hebrew letters are on the keyboard (based on the QWERTY layout).
And this tinycards deck teaches the letters, and the sounds they can make.
EDIT: That typing link has issues with the punctuation keys (which are important, since ת, for example, is on the comma key). This one also teaches the location of the letters for typing, without that issue, (and reinforces the letter names, which is nice).
