fingers

“finger”是規(guī)則可數(shù)名詞，其復(fù)數(shù)形式直接在詞尾加-s，即“fingers”。independent;independence

“depend”是動(dòng)詞“依靠；依賴”，其形容詞“獨(dú)立的”是“independent”；名詞“獨(dú)立”是“independence”。fairness;unfair

“fair”是形容詞“公平的”，其名詞“公正性”是“fairness”；形容詞“不公正的”是“unfair”，是在“fair”前加否定前綴“un-”。illness

“ill”是形容詞“生病的”，其名詞“疾病”是“illness”。development

“develop”是動(dòng)詞“發(fā)展”，其名詞“發(fā)展”是“development”。二。翻譯短語

takeouttherubbish

“倒垃圾”常見的英文表達(dá)是“takeouttherubbish”。allthetime

“頻繁；一直”可以用“allthetime”來表示。assoonas

“一……就……”用“assoonas”引導(dǎo)時(shí)間狀語從句。inorderto

“目的是；為了”常用“inorderto”，后接動(dòng)詞原形。dependon

“依靠；依賴”是“dependon”。takecareof/carefor

“照顧”可以表達(dá)為“takecareof”或者“carefor”。三、用所給單詞的適當(dāng)形式填空

reading

“finishdoingsth.”是固定用法，表示“完成做某事”，所以“read”要用動(dòng)名詞形式“reading”。outgoing

“as+形容詞/副詞原級(jí)+as”表示“和……一樣……”，這里是比較性格，用形容詞“outgoing”的原級(jí)，所以填“outgoing”。togo

“invitesb.todosth.”表示“邀請某人做某事”，所以“go”要用不定式形式“togo”。harder

“The+比較級(jí)，the+比較級(jí)”表示“越……，就越……”，這里表示“你工作越努力，以后取得的進(jìn)步就越大”，“hard”的比較級(jí)是“harder”，所以填“harder”。opening

“Wouldyouminddoingsth.”表示“你介意做某事嗎”，所以“open”要用動(dòng)名詞形式“opening”。tostay

“Itis+形容詞+todosth.”是固定句型，其中it是形式主語，真正的主語是后面的動(dòng)詞不定式，所以“stay”要用不定式形式“tostay”。四、單項(xiàng)選擇

C

“makethebed”是固定短語，表示“整理床鋪”；“maketea”表示“泡茶”，中間不需要加冠詞，所以選C。A

“be+形容詞+enough+todosth.”表示“足夠……去做某事”，這里表示“我們足夠大可以幫忙做家務(wù)了”，所以用動(dòng)詞不定式“tohelp”，選A。B

“finishdoingsth.”表示“完成做某事”，所以“write”要用動(dòng)名詞形式“writing”，選B。B

“Itis+形容詞+forsb.+todosth.”表示“做某事對某人來說是……的”，這里表示“吃太多垃圾食品對你不好”，所以用動(dòng)詞不定式“toeat”，選B。A

“The+比較級(jí)，the+比較級(jí)”表示“越……，就越……”，這里“feel”是系動(dòng)詞，后面接形容詞，“happy”的比較級(jí)是“happier”，所以選A。D

“work”是不可數(shù)名詞，前面不需要加不定冠詞；“job”在這里是特指“在二十分鐘內(nèi)要完成的工作”，用定冠詞“the”，所以選D。A

在if引導(dǎo)的條件狀語從句中，遵循“主將從現(xiàn)”的原則，即主句用一般將來時(shí)，從句用一般現(xiàn)在時(shí)，從句主語“he”是第三人稱單數(shù)，動(dòng)詞“finish”要用第三人稱單數(shù)形式“finishes”，所以選A。A

“inamess”是固定短語，表示“雜亂；混亂”，所以選A。五、閱讀理解

D
