step i lead in包子要蒸多久
t: good morning afternoon, class!
苹果怎么挂电话ss: good morning afternoon,mr/ms…
t: in this class, we are going to start unit 11 scientific achievements .now pay attention to the two words. will you plea tell me how the two words are formed?
s1“scientific”is the adjective form of” science”.
s2:“achievement “ is the noun form of “achieve”.
t: obrve them carefully; can you explain how they are formed?
s3:” science” is a noun, if we add –fic to it, then we get its adjective.
s4: “achieve” is a verb. if we add –ment to it, we get its noun.
t: excellent ! that is how the two words are formed. the basic part of any word is the root; to it, you can add a prefix at the beginning and/or a suffix at the end to change the meaning. for example, in the word "unflattering," the root is simply "flatter," while the prefix "un-" makes the word negative, and the suffix "-ing" changes it from a verb into an adjective (specifically, a participle).this is the grammar we are going to learn in this class.(show word formation on the powerpoint.)
step ii grammar
ask students to obrve the given words carefully and find out how words are formed.艺术字设计在线生成
t: how do learners improve their vocabulary? there are no super shortcuts to vocabulary, but there are various forms of support. here is one example. increasing your vocabulary is so important that you just can't forget about it. don't bury your head in the sand. ok.. plea look at the following words and tell how they are formed. (show the following words on the powerpoint.)
• affix
• infix
• prefix
• suffix
teacher explains the following.
t: what do the words (nouns) have in common?
ss: all of them contain the root “fix”.
t: well, they do have a number of things in common. let's ttle for the most obvious, the 'f
ix' at the end. so if we split them, this is what we get
• af + fix
• in + fix
• pre + fix
• suf + fix (the will be shown on the powerpoint)
t: what does 'fix' mean?
爱因斯坦的发明有哪些ss: fix means attach to, fasten, stick, glue.
t: what about 'af' , 'in' , 'pre' , 'suf' ? in' and 'pre' are understandable, aren't they ?
'in' a room, 'in' a ntence, 'in' a word.
'pre' means before like in pre-war, pre-school, premature.
so what do infix and prefix actually mean? infix - to attach something inside (a word).prefix - to attach something at the beginning of (a word)
what about 'af' and 'suf'?
that's a bit more difficult to explain. 'af' is actually from the beginning the latin word 'ad', and the meaning is the same as the english word add. add 4 and 5 and you get 9.
'suf' is the latin word 'sub', like in submarine, subway, suburb. the meaning is under, after (outside).
why have the d in 'ad' and the b in 'sub' changed into f?
the reason is really quite simple. 'adfix' and 'subfix' are difficult to pronounce. there is economy in everything! you simply leave out the d and the b, but in order to mark their existence the words are spelt with an extra f .
so what do affix and suffix actually mean?
电影梅兰芳ss: affix - to attach something to (a word)
suffix -to attach something at the end of (a word)
t: we have now fixed the fixes, haven't we? affix - something you add (stick) to a word
there are three kinds of affixes:
added inside the word - infix
added at the beginning of the word - prefix
added at the end of the word – suffix
ss: what's this good for then?
t: well, there are thousands of words with prefixes and suffixes. the infixes are fewer and less uful to you.
the english vocabulary basically consists of words of latin and germanic origin. there are prefixes in both groups.
if you know the basic meaning of a prefix or a suffix you can often 'guess' the meaning of an english word. there are a limited number of latin prefixes and suffixes. if you learn the meaning of them, and learn to recognize them in english words, you will increa your vocabulary much faster.
here are some of the most common latin prefixes (for the meanings of the latin roots, look up the words in a good dictionary): (show the following on the powerpoint.)
ab
(away) abstain, abnt, absolve
ad
(to) adverb, advertiment, advance, adjoin
in /il-/im-/ir-
(not) incapable, indecisive, intolerable , illegal, impossible, irrugular
inter
(between, among) international, interaction interdependent, interprovincial
pre
(before) prerecorded, preface prefer
post
(after) postpone, postscript, postwar
sub
(under, not quite) subsoil, subscription, suspect ,subway, subnormal
trans
(across, to a changed state) transfer, transit, translate, transport ,transform
