Answer 1

[體裁]說明文

[話題]衛(wèi)生與健康

[大意]材料介紹了人體肌肉的一些情況。

81. even。該句意思是“沒有肌肉的話，你 無法走路、說話、微笑，甚至無法呼 吸”。

82. sends。當(dāng)你想動的時候，你的大腦會 “傳遞”信息給肌肉。因為主語your brain是單數(shù)可數(shù)名詞，因此該空填動 詞的第三人稱單數(shù)形式。

83. them。_該空填them.，指代該句中的 bones。因為所填單詞在句中作賓語，

所以該空填代詞的賓格形式。

84. So。因為肌肉只能拉動骨骼，不能變 長或推動骨骼，“所以”大多數(shù)肌肉成 對發(fā)生作用。

85. jumping。由連詞and可知該空要填一 個和running并列的詞。根據(jù)方框中 所給的詞，可知選jump,且用jump的 動名詞形式。

86. quietly。該句意思是“甚至當(dāng)你安靜站 立的時候你的肌肉也在工作”。因.為 所填詞語在句中修飾動詞standing ,所 以該空填quiet的副詞形式。

87. support。由句子后半部分的keep you from falling down可知這里要表達的 是:腿部、臀部、背部和頸部的肌肉會 進行收縮，來“支撐”骨骼。

88. new。由轉(zhuǎn)折連詞but可知該空和后 半句中的the ones you have構(gòu)成轉(zhuǎn)折 關(guān)系，因此該空填new。

89. stronger。你的肌肉.動得越多，就會 變得越“強壯”。“the +比較級(+...) , the +比較級(+•••) ”表示“越……，就 越…”。

90. exercise。該句意思是“如果你不經(jīng)常 鍛煉你的肌肉，它們就會變得越來越軟弱無力”。
