本题考查need用法。need需要,作为实义动词时,后面接动词不定式to do sth表示“需要做某事”,或直接加名词或代词,表示“需要……”;作为情态动词时,后面接动词原形。空格后面有名词“help”,此处“need”为实义动词,根据句意“我们可以独立做事”,此处为否定,实义动词的否定借助助动词,主语为“we”,用don't。故选A。

考查动词need的用法。need作情态动词时,后接动词原形(但此处需表示“必须”的强制语气,且情态动词need多用于否定/疑问句);need to“需要做某事”,为实义动词结构,后接不定式;don’t need不需要,实义动词。根据“...finish your homework first”可知此处表示“需要先完成作业”,是实义动词结构。故选B。

A.doesn’t need B.needn’t C.didn’t need D.needs
【答案】A
【详解】句意:飞行员不需要任何帮助。他可以自己处理。
考查动词need的用法。need作情态动词时,否定形式为needn’t,其后接动词原形;need作实义动词时,其后直接加宾语,其否定形式是在前面加助动词do、does或did,再加not。根据“He can manage it himself.”可知,此处指飞行员不需要任何帮助,句子为否定句,且时态为一般现在时,空处应用doesn’t need。故选A。

考查情态动词。根据“we can solve it by ourselves”可知,空处应表达不需要来了,need作为情态动词,否定形式是needn’t,后面加动词原形,need作为实义动词时,否定形式需借助助动词don’t/doesn’t/didn’t,后接need to do sth,空后come为动词原形。故选B。
26.—Must I do my homework today?

A.doesn’t need to B.needn’t C.need not D.doesn’t need
【答案】D
【详解】句意:Alice擅长语文,所以我认为她不需要我们的帮助。
考查need动词用法。need需要,实意动词;needn’t/need not不必,情态动词,后跟动词原形。根据“Alice is good at Chinese, so I think she…our help.”可知,擅长语文所以不需要帮助,空后是名词,所以直接用doesn’t need即可。故选D。
29.—Mum, must I stay there the whole day?
—No, you ________. You ________ come back after lunch if you like.
A.mustn’t; can B.needn’t; must C.can’t; need D.needn’t; can
【答案】D
【详解】句意:——妈妈,我必须在那儿待一整天吗?——不,你不必。午饭后你可以回来,如果你愿意。
考查情态动词。mustn’t禁止;can可以;needn’t不必;must必须;can’t不能;need需要。Must开头的一般疑问句,且根据答语中“No”可知,不必一天都待在那里,故用needn’t,可排除AC选项;根据“if you like”可知,前面表达你可以在午饭后回来,故用can。故选D。
30.My uncle’s family is very poor, so he ________ work hard to support his family.
A.need to B.needs C.needs to D.needed to
【答案】C
【详解】句意:我叔叔的家庭很穷,所以他需要努力工作来支撑他的家庭。
考查动词need的用法和时态。need“需要”作情态动词时没有三单形式,且后接动词原形,选项均不符合,所以句子中的need应是作实义动词。根据“My uncle’s family is very poor, so he...work hard to support his family.”可知,此处是need to do sth.“需要做某事”,而句子叙述事实,时态为一般现在时,主语是he,此时谓语动词用三单形式needs。故选C。
二、单词拼写(本大题共10小题,每小题4分,共40分)
31.I think eating too much food is an (health) lifestyle.
【答案】unhealthy
【详解】句意:我认为吃太多食物是一种不健康的生活方式。句中缺少定语,修饰“lifestyle”。“health”是名词,其形容词形式“healthy”,根据“eating too much food”可知是不健康的,需用“unhealthy”。故填unhealthy。
32.“It’s (fair)! You can’t treat me like that.” Tom shouted angrily.
【答案】unfair
【详解】句意:“这不公平!你不能那样对待我。”汤姆生气地喊。根据“You can’t treat me like that.”可知,此处指这不公平,unfair“不公平的”符合题意。故填unfair。
33.It’s (possible) for us to finish such a difficult task in only a week.
【答案】impossible
【详解】句意:对于我们来说,仅在一周内完成如此困难的一项任务是不可能的。“It’s+形容词+for sb.+to do sth.”是固定句型,表示“对于某人来说做某事是……的”,结合语境“such a difficult task in only a week”可知,这是很难做到的,所以此处要用possible“可能的”的反义词impossible“不可能的”,即完成这项任务是“不可能的”。故填impossible。
34.More birds will (appear) if we don’t take action to protect the environment.
【答案】disappear
【详解】句意:如果我们不采取行动保护环境,更多的鸟类将会消失。根据“if we don’t take action to protect the environment”可知,如果不采取行动保护环境,更多的鸟类将会消失,此处填动词appear“出现”的反义词disappear“消失”,will后接动词原形。故填disappear。
35.Unluckily, he was told that the doors had been installed . (correct)
【答案】incorrectly
【详解】句意:不幸的是,他被告知门的安装不正确。分析句子结构,此空填副词修饰动词“installed”,且句首为“Unluckily不幸的是”,因此“门的安装是不正确的”,“correct正确的”要加反义词前缀“in”。故填incorrectly。
36.Don’t make much noise in public. It’s (polite).
【答案】impolite
【详解】句意:不要在公共场合制造太多噪音。这是不礼貌的。根据“Don’t make much noise in public”可知,在公共场合制造太多噪音是不礼貌的,应用形容词impolite“不礼貌的”,故填impolite。
37.Mike sounded after being asked the same question for many times. (patient)
【答案】impatient

38.Don’t eat too much at a time, or you’ll feel (comfortable).
【答案】uncomfortable
【详解】句意:一次不要吃太多,否则你会觉得不舒服。根据“Don’t eat too much at a time,”可知,如果一次吃太多,你会觉得不舒服,空处用形容词uncomfortable“不舒服的”,作表语。故填uncomfortable。
39.I am tidy but my brother is (tidy).
【答案】untidy
【详解】句意:我很爱整洁,但我弟弟很不整洁。根据“but”可知,与前句形成转折关系,是不整洁,untidy符合句意;故填untidy。
