We usually add -er to short adjectives and use more with long adjectives to form comparatives.（Tip: Short adjectives are adjectives with one or two syllables, e.g. clean, heavy. Long adjectives are adjectives with three or more syllables, e.g. beautiful, interesting.）She is shorter than I am.My book is more interesting than his.We use the + superlatives to compare three or more people or things. We usually add -est to short adjectives and use most with long adjectives to form superlatives.He is the tallest boy in our class.This is the most expensive computer in the shop.We form comparative and superlative adjectives like this:数量的比较Comparing the amount of thingsWe can compare the amount of things using more ... than, fewer ... than and less ... than. We use the most for the largest amount and the fewest/the least for the smallest amount.Millie has more tomatoes than Daniel.Millie has less rice than Daniel.Millie has fewer bananas than Kitty.Kitty has the most eggs.Daniel has the fewest tomatoes.Millie has the least juice.副词比较级和最高级Comparative and superlative adverbsWe can form comparative and superlative adverbs in the same way we form comparative and superlative adjectives.Millie came third in the race. She ran fast.Sandy came second in the race. She ran faster than Millie.Amy came first in the race. She ran the fastest.We form comparative and superlative adverbs like this:as…as的用法Using as ... asWe use as ... as to say that people or things are the same in some ways.Mr Wu is as happy as the two girls.We use not as ... as to say that people or things are not the same in some ways.The two girls are not as tall as Mr Wu.=The two girls are shorter than Mr Wu.反身代词Reflexive pronounsWe use reflexive pronouns when the subject and the object are the same person or thing.Linda enjoyed herself in the park.Linda’s parents will go and see the photos for themselves.祈使句Giving instructionsWe start a sentence with the base form of a verb when we want to tell people what to do.Put up a picture on the wall.Paint the walls blue.We add do not/don’t in front of a verb when we want to tell people not to do something.Don’t paint the cat.We often add please in a sentence to make an instruction more polite.Please fix the shelf for me.Don’t touch the wet paint, please.用should和had better提建议Using should and had betterWe use should and had better when giving advice and telling people what we think is the best or right thing to do. The tone of had better is stronger than should.You should know a little about DIY.You should not put so many books on the shelf.Your watch is broken. You had better buy a new one.You had better not be late for school.情态动词may的用法Using may for possibilityWe use may to say that something is possible.If we do nothing, soon there may be none left!The bamboo forests are becoming smaller and smaller. As a result, pandas may not have a place to live or food to eat.动词不定式作宾语Using verbs + to-infinitivesWe can use verbs and to-infinitives together.At four months old, she started to go outside for the first time.When she was six months old, she began to eat bamboo.When she was 20 months old, she learnt to look after herself.We often use to-infinitives after these verbs.动词不定式作目的状语Using to-infinitives for purposeWe can use to-infinitives to express purpose.I often go to the market to watch the birds.Now the Chinese government has made laws to prevent all these things.We can also use in order to to express purpose. This is more formal than using to-infinitives.Some people want to make the wetlands smaller in order to have more space for farms and buildings.Take a notebook with you in order to write down what you see.动词不定式作宾语补足语Using verbs + objects + to-infinitivesWe can use some verbs with objects and to-infinitives.We are now inviting them to help us.We need more people to count and describe the birds.We add not before to-infinitives to express a negative meaning.We ask people not to catch birds for any reason.We can use some verbs in this structure with infinitives without to. make or let + object + infinitive without toMax tells funny jokes and often makes me laugh.Mr Wu agreed to let me join their school trip.see or hear + object + infinitive without toShe saw a baby panda drink her mother’s milk.Millie and Amy heard someone sing in the park.help + object + infinitive with or without toThis will help people (to) understand the importance of the wetlands.动词及基本句型Verbs and sentence structuresThe basic parts of a sentence are the subject (S), the verb (V) and the object (O). Usually a statement begins with the subject and the verb. We divide verbs into three kinds: intransitive verbs (vi.), transitive verbs (vt.) and linking verbs (linking v.).An intransitive verb does not take an object. The sentence structure is like this:A transitive verb takes an object. The verb tells us what the subject does to something else (the object). The sentence structure is like this:A linking verb links the subject and the adjective phrase or noun phrase that describes it.A word or a group of words that follows a linking verb is the predicative (P). The sentence structure is like this:过去进行时Past continuous tenseWe use the past continuous tense to talk about things that were happening at a particular time in the past.when, while和as的用法Using when, while and asWhen, while and as can be used as conjunctions of time. They all mean”during the time that”.I was sleeping when the earthquake started.People were running in all directions while pieces of glass and bricks were falling down.As I was trying to find my way out, I suddenly heard some noise above me.Note: When a shorter action happened at the same time as a longer action, we use thepast continuous tense for the longer action and the simple past tense for the shorter action. When there are two long actions, we often use while.If the shorter action is in the main clause, we can use when, while or as to join them.When/While/As Millie was watching TV, Andy came into the room.If the longer action is in the main clause, we often use when to join them.Millie was watching TV when Andy came into the room.八年级下册现在完成时Present perfect tenseWe use the present perfect tense to talk about an action that started in the past and continues to the present.I have lived here since I was born.We use the present perfect tense to talk about an action that happened in the past and has a connection with the present.Eddie has just eaten Hobo’s food.(Eddie ate the food, and now Hobo has nothing to eat.)We also use the present perfect tense to talk about how many times an action has happened till now.I have already read this book many times.We make positive statements in the present perfect tense like this:We make negative statements in the present perfect tense like this:We ask and answer questions using the present perfect tense like this:We form the past participles of regular verbs by adding -ed, just as what we do to form the simple past tense of these verbs.We form the past participles of irregular verbs differently.
