Summarize the following:
Chances are good that the grammar rules of your target language will be quite different from that of your native language. Spending some time learning how sentences are structured, such as the word order, parts of speech, and subject-verb agreement, will help you in the long run. Words that you would use daily should be the first ones you learn. Try starting with personal pronouns (I, you, she, he, they, etc.) and common nouns (boy, girl, chair, table, city, teacher, restroom, school, airport, restaurant, etc.) before moving on to adjectives (green, thin, fast, beautiful, cold, etc.) or verbs (go, do, take, leave, offer, meet, etc.), which will need to be conjugated. You'll likely want to figure out how to ask a few simple questions, such as "Where is the restroom/train station/hotel/school?" and "How much does this (coffee, newspaper, train ticket) cost?" You'll also probably want to learn to say "My name is" "What is your name?" "How are you doing?" and "I'm doing well/poorly." Think of a few dozen phrases you want to know and start with those. One word may make you think of another. Try to build mental images or draw pictures based on connections. It doesn't matter how obscure or silly they may seem if it will help you remember. Repetition is one of the best ways to learn vocabulary. Make flash cards with your vocab words and go through them daily. You can even post the cards around your room or home so that you see them often. You can also use an automated flashcard generator (e.g., lingua.ly).

summary: Study the grammar rules. Start with common vocabulary. Learn basic phrases. Make associations. Practice.

Summarize the following:
When you obtain new shells for your hermit crab, it is very important for you to make sure the shells are safe and sanitary. You can do this by boiling your shells. First, use a brush to remove any sand or debris from in the inside and outside of your shell. Then, submerge your shells in boiling distilled water, and boil them for 15-20 minutes. After your shells have been boiled, they must be moistened with ocean water, or salt water. (Purchasing a saltwater solution from a pet store is the most effective option.) As you wait for your crab to select a new shell, you will want to periodically re-moisten the insides of your shells. This will draw you hermit crab toward the shells, and make the shells more attractive to him. Avoid tap water. Most tap water contains trace amounts of copper or other heavy metals. Hermit crabs are extremely sensitive to these metals, and they can hurt your crab. Once your shells have been properly prepared, place them where your crab can see them. Position them out in the open, on the ground level (substrate) of your crab's habitat, so that your crab will encounter them daily. Once a week (or every other week) you may want to remove the shells, wait a few hours, and then put them back. If your crab has become accustomed to the shells, he may not really recognize them anymore. Removing and reintroducing them may encourage your crab to investigate, and possibly even change shells. This is also a good time to re-moisten your shells with saltwater.
summary: Boil new shells. Moisten shells with saltwater. Place shells where the crab can see them.
