Volunteering: revisit perfect tense

Revisit sound-symbol correspondences to strengthen listening, speaking, reading aloud, and writing skills. Form the perfect tense with a present form of 'haben' or 'sein', plus a past participle, e.g., 'ich habe das gemacht'. The past participle of many verbs is: ge- + verb stem + -t. Some strong verbs use ge- + verb stem + -en. Verbs that start with unstressed prefixes be-, ver-, ent-, er- do not add ge-, e.g., ‘er hat besucht’. The past participle ‘gefallen’ is used with ‘sein’ for ‘fallen’ (‘to fall’) and ‘haben’ for ‘gefallen’ (‘to please’).
