People who are obese have 【9】 (low) levels of brown fat than thinner people. Head researcher Hei Sook Sul said: "This protein could become an important target for research into the treatment and prevention of obesity and obesity-related diseases."

Answer 1

【答案】

【2】which

【3】in

【4】comfortable

【5】are exposed

【6】a

【7】compared

【8】One

【9】lower

【10】possibly

【解析】

試題分析：科學(xué)家發(fā)現(xiàn)處在冷的狀態(tài)能幫助減肥。

【1】staying 考查非謂語動詞。分析結(jié)構(gòu)可知，此處是非謂語作主語，用動名詞形式，填staying。

【2】which 考查關(guān)系代詞。在非限制性定語從句中缺少主語，用關(guān)系代詞which指代前句話內(nèi)容。

【3】in 考查介詞。句意：白色脂肪儲存能量，導(dǎo)致肥胖。result in導(dǎo)致，造成。故填in。

【4】comfortable 考查形容詞。此處是和constant并列作temperatures的定語，故用形容詞形式。

【5】are exposed 考查謂語動詞。expose是及物動詞，句中沒有賓語，判斷用被動形式。be exposed to “被暴露在……之下”，根據(jù)主謂一致原則，填are exposed。

【6】a 考查冠詞。a significant amount of“大量的”。故填a。

【7】compared 考查非謂語動詞。此處是“連詞+分詞”結(jié)構(gòu)，compare和句子主語outdoor workers之間是被動關(guān)系，用過去分詞，填compared。

【8】One 考查數(shù)詞。從上文內(nèi)容可知，此處指兩組中的一組，因位于句首，故填One。

【9】lower 考查比較級。根據(jù)句中than可知，此處用比較級，修飾名詞levels，用形容詞，故填lower。

【10】possibly 考查副詞。修飾動詞用副詞形式，故填possibly。

【知識拓展】

1.compare...with...把……和……比較(常表示同類相比，比較)

compare...to...把……比作……(常表示異類相比，比喻)

①Let's compare this photo with that one. 讓我們把這張照片和那張照片作一下比較。

②Children are often compared to happy birds. 孩子常常被比喻成幸福的小鳥。

2.Compared to/with---，----。與---相比較。Compared to those boys，you are lucky.與那些男孩相比較，你是幸運的。

【知識歸納】

以e結(jié)尾的形容詞變成副詞時，有的直接加ly ;有的把e去掉再加ly.

possible---possibly； simple---simply; gentle---gently; terrible---terribly; true---truly; flexible---flexibly；immediate--- immediately; brave---bravely; wise---wisely；active---actively
