Abstract
Although claims about the nature of EFL/ESL learners’ knowledge (i. e., implicit and/or explicit) are essential to many debates in foreign/second language development, few studies have sought to evaluate the effects of linguistic and/or contextual variables on the two knowledge types. This study, accordingly, undertook to examine the effects of different explicit and implicit types of form-focused instruction (FFI) on the acquisition of four easy and difficult forms as assessed by different implicit and explicit outcome measures. The instruments utilized to assess students’ learning were: oral elicited imitation, untimed and timed grammaticality judgment, and metalinguistic knowledge tests. A pretest and two posttests were administered to 150 novice learners immediately after FFI and again after a 4-week delay. Immediate and durable effects of FFI were found for the easy and difficult target forms on both implicit and explicit knowledge measures. Specifically, the study indicated that explicit and implicit types of FFI were significantly more beneficial for explicitly-easy and implicitly-easy language forms respectively. The findings of this study may contribute a different set of insights to our understanding of the efficacy of varying types of FFI on learners’ controlled and/or spontaneous use of easy and difficult structures at early stages of L2 development.

Plural -s
Possessive –s
Possessive adjectives
Possessive Pronouns
Present progressive –ing
Regular past tense –ed
Third person present tense’s’
Indefinite article (a/an)
Demonstrative Adjectives
Comparatives
Superlatives
Yes/No questions
Since/For
Unreal conditionals (The main clause in an unreal conditional sentence requires the use of a past modal+ have+Ven)
Question tags
Dative alternation (Whereas verbs like ‘give’ permit two sentence patterns (… V+IO+DO and … V+DO+IO) verbs like ‘explain’ only permit one sentence pattern (… V+DO+IO))
Embedded questions (Questions that are reported (i. e. are indirect rather than direct) require declarative word order (i. e. there is no subject–verb inversion))
Modals (Modal verbs such as ‘may and ‘can’ are followed by the base form of the main)
WH- Questions (about a direct object)
Adverb placement (Adverbs can be positioned sentence initially and finally and also between the subject and the verb but not between the verb and the direct object.)
Verb complements (Some main verbs (e. g., want) take an infinitival complement whereas others (e. g., suggest) take a gerund complement)
Ergative verbs (Ergative verbs like ‘increase’ must take the active voice unless the sentence contains an explicit or readily inferred agent that caused the process to occur.)
Relative clauses (Relative clauses in English where the relative pronoun functions as object; such clauses do not allow a resumptive pronoun.)

Strange Bird
Birds have wings and feathers and they can usually fly. But Kiwi is an unusual bird because it cannot fly and it has no wings or tail. It only lives in New Zealand. A Kiwi likes to live near a lot of trees. It sleeps during the day, because the sunlight hurts a Kiwi’s eyes. It smells things very well. The police say that people cannot kill or catch Kiwis. New Zealanders want these birds to live.
Losing a job
This month, Tom is having difficulty because his factory fired several people, including Tom! Usually, he works at a dairy factory where he is an engineer. However, the factory has to make budget cuts and they are unable to keep all of the people.

Meanwhile, Tom is trying to spend less money until he finds a new job.

(Part 2)
Read the passage below. Find at least one example in the passage for each of the grammatical features listed in the table.
What do young people do in their free time? Research shows that they are watching more TV today than they did twenty years ago. Cellphones are also changing the way young people use their free time. Today the youth are spending more time doing things on their Cellphones. Surfing the Internet on their Cellphones is becoming another common free-time activity. In fact, some managers are finding that young workers are skipping lunch to surf the Internet.
More and more, young people are mixing their work time and play time. They talk on their cellphones while they are trying to get to work. They read work papers while they are eating. They listen to music while they are studying. Maybe this is why the youth’s lives have changed and they think that they have less free time these days.

| Possessive –s | |
| Present progressive –ing | |
| Third person -s | |
| WH-question about a direct object |
