　　英語(yǔ)四級(jí)考試選詞填空專項(xiàng)習(xí)題答案

　　36.E

　　語(yǔ)法判斷：exercise后是and，而and前后應(yīng)為并列結(jié)構(gòu)(又稱平行結(jié)構(gòu))，因?yàn)閍nd后為gorging on comfortfood，所以前面也應(yīng)當(dāng)是現(xiàn)在分詞短語(yǔ)，因此應(yīng)填入現(xiàn)在分詞。備選項(xiàng)中只有shunning是現(xiàn)在分詞，因此答案很明確。

　　語(yǔ)義判斷：shun：(故意或習(xí)慣地)避免;回避，躲開。從語(yǔ)義上判斷也是正確的。

　　37.G

　　語(yǔ)法判斷：此處應(yīng)為定語(yǔ)來(lái)修飾fmdings，后為by，而過去分詞既表示被動(dòng)又可用作后置賓語(yǔ)，所以此處應(yīng)填入過去分詞。

　　語(yǔ)義判斷：備選的過去分詞或過去式有reached、highlighted、blamed、released、lost、admitted、treated、dieted、failed，但從上下文語(yǔ)義判斷，意思應(yīng)為：由減重中心XLS醫(yī)院發(fā)布的調(diào)查或研究結(jié)果，所以應(yīng)選擇released。

　　38.N

　　語(yǔ)法判斷：空格前的the是冠詞，空格后的majority是名詞，因此應(yīng)當(dāng)填入定語(yǔ)。

　　語(yǔ)義判斷：符合語(yǔ)法條件的詞有很多：massive、reached、highlighted、blamed、lost、admitted、treated、dieted、overall、vast、failed，而avastmajority是個(gè)近乎固定的搭配，意為“大多數(shù)”，故本題選N。

　　39.J

　　語(yǔ)法判斷：此句缺謂語(yǔ)，后接一個(gè)省略了that的賓語(yǔ)從句。可作謂語(yǔ)的選項(xiàng)有reached、highlighted、blamed、lost、admitted、treated、dieted、failed，根據(jù)文章，可知只有admitted符合。

　　語(yǔ)義判斷：該句意為：五分之一的節(jié)食減肥者承認(rèn)自己在第四五天的時(shí)候就堅(jiān)持不住了。

　　40.I

　　語(yǔ)法判斷：此句主、謂、賓都不缺，而空格出現(xiàn)在were和blamed之間，所以應(yīng)為狀語(yǔ)，因而應(yīng)填入副詞。

　　語(yǔ)義判斷：備選的副詞有still、also和overall，上文提到了饑餓是人們放棄減肥的原因之一，而此處提到單調(diào)乏味和酒精的刺激也是讓人們放棄減肥的原因，因而從語(yǔ)義上判斷，只有also符合上下文意。

　　41.C

　　語(yǔ)法判斷：此句缺謂語(yǔ)，應(yīng)填入動(dòng)詞，其后接賓語(yǔ)從句。

　　語(yǔ)義判斷：備選的動(dòng)詞有reached、highlighted、blamed、lost、treated、dieted、failed，但從上下文語(yǔ)義判斷，此處意思應(yīng)為：國(guó)家肥胖論壇醫(yī)療主任馬特·凱普霍恩博士強(qiáng)調(diào)說，僅僅一天不堅(jiān)持節(jié)食就會(huì)毀掉一周的努力。highlighted符合此處語(yǔ)法和語(yǔ)義的要求。

　　42.A

　　語(yǔ)法判斷：a和590，000之間應(yīng)該是形容詞。

　　語(yǔ)義判斷：備選的形容詞還有massive和overall，從上下文語(yǔ)義判斷massive應(yīng)為正確選擇。

　　43.O

　　語(yǔ)法判斷：could already have后應(yīng)為過去分詞。

　　語(yǔ)義判斷：備選的過去分詞有reached、blamed、lost、treated、dieted、failed。從上下文語(yǔ)義判斷，此處的意思應(yīng)為：調(diào)查結(jié)果顯示，有多達(dá)59萬(wàn)人可能已經(jīng)放棄了新年減肥計(jì)劃。因而failed是語(yǔ)法判斷和語(yǔ)義判斷后的最佳選擇。

　　44.M

　　語(yǔ)法判斷：此句主、謂、賓完整，應(yīng)填入副詞。

　　語(yǔ)義判斷：備選的副詞還有still和overall。overall意為“總體上，總的來(lái)說”，符合此處的語(yǔ)法和語(yǔ)義要求。

　　45.B

　　語(yǔ)法判斷：空格前面是they’ve，故后面應(yīng)接過去分詞。

　　語(yǔ)義判斷：空格后為targetweight(目標(biāo)體重)，故按照語(yǔ)義和固定的搭配來(lái)進(jìn)行判斷，應(yīng)為reached，即“達(dá)到目標(biāo)體重”。

　　英語(yǔ)四級(jí)考試選詞填空專項(xiàng)習(xí)題(二)
