Learn to listen.Before you learn how to speak, you’ll need to learn how to listen. 36 Did the speaker sleep or slip Did he hurt his chin (下巴) or his shin If you can hear the difference, it will be easier to speak the difference.
37 When you speak, you move your mouth.How you move your mouth affects how you pronounce a word.The first step to correcting your mouth shape is to notice it and pay attention.There are a few ways you can check that your mouth and lips are making the correct shape, for example, using a mirror. 38
Pay attention to your tongue.The main difference between rice and lice is in your tongue.When you speak, you move your tongue to make sounds.You probably didn’t even notice that, since you do it without thinking.To improve your English pronunciation, it’s a good idea to check what your tongue is doing.Some difficult sounds for non-native speakers to make are the letters “L” and “R”, and the sound “TH”. 39
Break words down into sounds.Words are made up of syllables (音节), or parts．The word “syllable”, for example, has three syllables: syl-la-ble． 40 To check how many syllables a word has, place your hand flat just under your chin．Say the word slowly.Each time your chin touches your hand, that’s a syllable.
Pronunciation is important for you to learn English well．Just remember: Practice makes perfect!
A．Notice how your mouth and lips move.
B．You can even write the word down in parts.


believed that practice makes perfect.

4、昆明市第一中学2025届高三第八次联考(3月)化学答案


体心立方晶胞 晶胞参数(边长)为a，原子球半径为r，体对角线长为c，则有c＝a＝4r
面心立方晶胞 晶胞参数(边长)为a，原子球半径为r，则有4r＝a
六方最密堆积晶胞 晶胞中原子球半径为r，六棱柱边长为a，高为h，则有a＝2r，h＝2倍四面体高
金刚石晶胞 G点是空的，没有球，是正立方体的体心，A球心到E球心，是2个半径，即一个直径；同样，E球心到G，是2个半径，即一个直径，所以AG是两个直径，体对角线是AG的两倍，所以体对角线是4个直径，即8r，则有8r＝a
晶胞参数(边长)为a，原子球半径为r，则有8r＝a。(体对角线上五球相切，其中有两个假想球)
5.金属晶体空间利用率的计算方法
(1)空间利用率的定义及计算步骤
