人教版初中八年级上册英语各单元语法讲练

八年级上册单元语法和习题（答案在最后）一复合不定代词不指明代替任何特定名词或形容词的代词叫不定代词，它们有some,any,much,many等以及由every-,some-,any-,no-加上-thing,-body,-one构成的复合不定代词。下面我们主要学习有关复合不定代词的内容。1、复合不定代词的分类指物：everything,something,anything,nothing指人：everybody,somebody,anybody,nobodyeveryone,someone,anyone,noone2、复合不定代词的用法1.

◆some-类的复合不定代词一般用于肯定句中。如：Thereissomebodyatthedoor.

◆any-类的复合不定代词一般用于否定句或疑问句中，表示“某事；某物；某人”；也可用于肯定句或条件从句中，表示“任何东西；任何人”。如：Thereisn'tanythinginthebox.Didyouseeanybodythere?Ifanybodycomeshere,pleaseaskhimtowait.2.

复合不定代词作主语时，谓语动词常用单数形式。如：Everybodyknowshesingswell.3.

D.anything二频度副词频度副词表示事情发生的频率。常见的频度副词有always,sometimes,hardlyever,usually,often,never等。◆常见的频度副词的频率大小如图所示：◆

频度副词的位置:

频度副词通常放在实义动词之前，系动词、助动词或情态动词之后，但有些频度副词如sometimes，often等位置比较灵活，还可以放在句首或句尾。如：Davidusuallygetshomeataboutthistime.

Mysisterdoesn'talwaysreadinthelibrary.(注意：always

与not连用，表示部分否定，意为“并非总是”。若要表示全部否定，应用never。)Myfathersometimes/oftenworksattheweekend.Sometimes/Oftenmyfatherworksattheweekend.Myfatherworksattheweekendsometimes/often.◆

当对频度副词及表示事件发生频率的短语提问时，常用howoften，意为“多久一次”。如：·Bill

never

goestothecinema.

(对划线部分提问)

→HowoftendoesBillgotothecinema?·Iwashmyclothes

threetimesaweek.

(对划线部分提问)→Howoftendoyouwashyourclothes?Theteacherhardlygivesusatest.________________theteachergiveyouatest?Inevergetupbeforefiveo’clock?__________doyougetupbeforefiveo’clock?LiTaooftenhasriceforlunch.__________LiTaooften_____forlunch?IusuallyreadEnglishinthemorning.__________youusually______inthemorning?Mymothergoestoseemygrandparentstwiceamonth._______________yourmother_____toseeyourgrandparents?Ⅱ.

埃里克(Eric)多久打扫一次房间？_________________________________________三形容词、副词的原级和比较级大多数形容词和副词有三个等级：原级、比较级和最高级。本单元我们主要学习形容词、副词的原级和比较级的构成及其用法。◆

原级形容词、副词的原级即原形。1.

原级可用于句型“主语+be/

行为动词+as+

形容词

/

副词原形+as+比较对象.”，该句型表示两者在某一方面相同。当表示一方在某一方面不及另一方时，常用句型“主语+be+not+as/so+

形容词原形+as+比较对象.”或“主语+don't/doesn't/didn't+

行为动词原形+as/so+副词原形+as+比较对象.”。如：Thisdressisasbeautifulasthatone.Tomisn'tas/sotallasme.2.

原级前可用very，quite，too等副词修饰。如：I'mveryhungry.◆

比较级构成一．形容词比较级的变化1.规则变化（1）在形容词后直接加-er。如：tall-----taller，short------shorter等。（2）以不发音的字母e结尾的只需在末尾加-r。如：nice------nicer，large-------larger等。（3）以“辅音字母+y”结尾的形容词，要先把y变成i，然后再加-er。如：heavy------heavier，happy------happier等。（4）若以重读闭音节结尾且只有一个辅音字母，先双写这个辅音字母，然后再加-er。如：fat------fatter，hot------hotter等。（5）多音节和部分双音节的形容词，可不是在末尾变化，而是在前面加more。如：careful-----morecareful，athletic-------moreathletic等。2.不规则变化good/well------betterbad/badly-------worsemany/much-------morefew/little------less二．形容词比较级的用法在描述单个的某人或某物所具有的特征时，需要用形容词原级形式，当把两者进行比较时，就用比较级，常见的表示这类用法的句型有：1.“A+be+比较级+than+B”表示“A在某方面超过B”。如：Thisbookisdearerthanthatone.这本书比那本书贵2.“Which/Who(se)+be+比较级,AorB?”意思是“A和B，哪个更…….”。如：Whichisbigger,thesunortheearth?太阳和地球，哪个更大？Whosebagisheavier,yoursormine?谁的包重些，你的还是我的？3.“A+be+the+比较级+ofthetwo(……)”意思是“A是两者中较…….的一个。”这时前面一定要加the，表示特指。如：Lilyisthetallerofthetwins.莉莉是双胞胎中个子较高的那个。三．常与比较级连用的词1.前面可以加上alittle，alot，much，even，still等程度副词作修饰语。如：Sheismuchmorecarefulthanherbrother.她比她哥哥细心多了。2.前面还可以加表示数量、倍数的修饰语。如：MybrotheristwoyearsolderthanI.我哥哥比我大两岁。Thisroomistwicebiggerthanthatone.这个房间比那个房间大两倍。Ⅰ.

B.potatoes

C.rice

2.
