選修7 Unit 3 Under the sea 一、單項(xiàng)填空 1．______ big fire broke out in my neighbor’s house last night，and it took the firefighters about an hour to put out ______ fire. A．The；a　　　　　　　　 B．A；the C．The；the D．A；a 解析：考查冠詞。第一個(gè)空泛指“一場(chǎng)火災(zāi)”；而第二個(gè)空是特指上文已提及的火災(zāi)，所以答案為B項(xiàng)。句意：昨夜我的鄰居家里發(fā)生了一場(chǎng)火災(zāi)，消防員花了大概一個(gè)小時(shí)才將它撲滅。 答案：B 2．Ashley，______such cases，is sure instantly to come up with a brilliant idea. A．experiencing B．having experienced C．to experience D．experienced 解析：考查非謂語動(dòng)詞作狀語的用法。由后半句的“一定能想出一個(gè)出色的辦法”可以看出，那個(gè)年輕人一定經(jīng)歷過類似的情況。所以要用分詞的完成式，強(qiáng)調(diào)動(dòng)作的結(jié)果。 答案：B 3．I wonder ______ of you is ______ such an accident. A．who；to be blamed on B．whom；blaming to C．which；to blame for D．who；to be blamed for 解析：表示給定范圍內(nèi)的人，問“誰”時(shí)用which；be to blame for“因……而受到責(zé)備”。 答案：C 4．He is said ______ by a famous university，for which he has worked hard for three years. A．being admitted B．to being admitted C．to be admitted D．to have been admitted 解析：考查sb.is said to do結(jié)構(gòu)。動(dòng)詞admit發(fā)生在主句的謂語動(dòng)詞之前，因此D項(xiàng)符合。 答案：D 5．—I’m sorry to have interrupted you.Please go on. —Then，where was I? —Oh.You ______ you didn’t adapt to the way that the people lived there. A．were saying B．had said C．said D．had been saying 解析：考查時(shí)態(tài)。對(duì)方問的是剛才被打斷的時(shí)刻談的是什么話題，所以說話人回答的是剛才對(duì)方正在說的內(nèi)容，因此用過去進(jìn)行時(shí)。 答案：A 6．I think he must have a dictionary you need，______ he? A．mustn’t B．doesn’t C．don’t D．hasn’t 解析：考查反意疑問句的構(gòu)成。情態(tài)動(dòng)詞表示推測(cè)時(shí)，其后的反義疑問句沒有表示過去的時(shí)間狀語時(shí)，由動(dòng)詞決定，動(dòng)詞have是行為動(dòng)詞，由主語he可知用doesn’t。 答案：B 7．One of the requirements for a fire is that the material ______ to its burning temperature. A．is heated B．will be heated C．be heated D．could be heated 解析：考查虛擬語氣。that引導(dǎo)的從句作requirements的表語從句，因此要用虛擬語氣“(should)＋動(dòng)詞原形”，should可以省略。 答案：C 8．We’ll continue to learn by ourselves when we have graduated.We must ______ learn how to study in the university now. A．in all B．a(chǎn)fter all C．a(chǎn)bove all D．a(chǎn)t all 解析：考查介詞短語辨析。above all表示“首先，最重要地”。句意：我們畢業(yè)后將繼續(xù)自學(xué)，但最重要地是現(xiàn)在要學(xué)會(huì)在大學(xué)里如何學(xué)習(xí)。 答案：C 9．Mary’s screaming made the girls ______ around her frightened. A．seated B．seating C．to seat D．seat 解析：考查非謂語動(dòng)詞。句意：Mary的尖叫聲把坐在她周圍的女孩們嚇壞了。由句意可知“______around her”做girls的定語，動(dòng)詞seat常用的結(jié)構(gòu)有be seated和seat oneself表示“就坐”，這里seated表示坐著的狀態(tài)，相當(dāng)于sitting，seat表示“坐著”時(shí)，如果用seating作補(bǔ)語、定語或狀語，其后面需要跟賓語。 答案：A 10．The boy who had been seriously injured in the mudrock flow was so well looked after in the hospital that he could ______ get out of bed without help. A．nearly B．merely C．barely D．hardly 解析：考查副詞辨析。句意：在泥石流中受傷的那個(gè)男孩在醫(yī)院里得到了如此好的照顧以至于他幾乎不需要?jiǎng)e人幫助就能下床了。nearly“幾乎”；can hardly和can barely都表示“幾乎不能”，表示否定，不合題意；merely“僅僅”。 答案：A 11．Is there a bookshop around ______ I can buy an EnglishChinese dictionary? A．which B．where C．that D．what 解析：where引導(dǎo)的是定語從句，修飾先行詞bookshop，around在此處是副詞“這附近”。 答案：B 12．In no country ______ Britain，as is often said，______ experience four seasons in a day. A．rather than；can one B．rather than；one can C．other than；one can D．other than；can one 解析：other than“除了”；rather than“而不是”；in no country位于句首，句子要部分倒裝。句意：據(jù)說除了英國外，再也沒有哪個(gè)國家能在同一天內(nèi)體驗(yàn)到四季。 答案：D 13．______ we have some sympathy for them，we don’t think they are right to do so. A．If B．While C．When D．As 解析：考查連詞的用法。句意：雖然我們有些同情他們，可是我們認(rèn)為他們這么做不對(duì)。此處的while表示“雖然，盡管”，用來引導(dǎo)讓步狀語從句。 答案：B 14．—Will you go to Qingdao for a holiday? —If your brother does，______. A．so do I B．so I do C．so will I D．so am I 解析：考查so引導(dǎo)的倒裝句。if從句中用的一般現(xiàn)在時(shí)，主句中要用一般將來時(shí)，因此選C項(xiàng)。答語句意：如果你兄弟去，我就去。 答案：C 15．—Thanks for your MP5.I’ll return it to you as soon as possible. —______.I’ve got a new one from my uncle. A．Nothing serious B．No hurry C．With pleasure D．Nothing much 解析：考查交際用語。由“I’ve got a new one from my uncle.”一句可知，前一句應(yīng)該用“No hurry.”。答語句意：不用著急。我從我叔叔那里拿來了一個(gè)新的。 答案：B 二、閱讀理解 1．From the first paragraph，we can know______. A．plants can only move a little B．plants do not need to feed C．plants can not get minerals by themselves D．plants are the most developed organisms on Earth 解析：細(xì)節(jié)理解題。根據(jù)第一段They do not have a mouth or a digestive system and they do not move much to find or catch their food可知，植物不能移動(dòng)很多去尋找或是捕食它們的食物，即可以移動(dòng)一點(diǎn)點(diǎn)。 答案：A 2．What does the second paragraph mainly talk about? A．What organic matter is. B．Water is very important to a plant. C．Why minerals exist in a plant. D．What a plant is made of. 解析：段落大意題。第二段主要介紹了植物的三種成分：水、礦物質(zhì)和有機(jī)物。 答案：D 3．What does the underlined word“wilt”in Paragraph 3 probably mean? A．Be cut off. B．Be broken. C．Dry out. D．Turn red. 解析：詞義猜測(cè)題。根據(jù)上文It is true that plants need a lot of water to stay healthy and plants are mostly made of water可知，植物需要很多的水來保持健康，植物主要由水組成。再根據(jù)If we do not water plants they will...and eventually they will die可知，沒有水，植物將會(huì)枯萎，最終死亡。由此可推知，畫線詞含義為“枯萎，干枯”。 答案：C B Anaconda This South American creature appears in films or your nightmares.They have weighed over 230 kilograms.It is often regarded as the biggest snake in the world.It is clearly a totally different brand of snake type as it coils(纏繞)all over its target，increasing the pressure until eventually its victim dies.Its jaws are powered by muscle tissue that produces enough power for its more than 100 sharp teeth to pass through the thick skin of a crocodile.They don’t have poison.Sometimes they prefer to camouflage themselves so that they look like their surroundings and swiftly draw back when someone approaches. Poisonous Frog The Golden Poison Frog is protected by means of a strong poison.This very small frog，less than 55 mm in length，has enough poison to take down a couple of African Bull Elephants.This frog has been known to be a killer of men and women who’ve touched it.It is also confirmed that dogs have died by contacting a tissue on which a Golden Poison Frog had wandered！While the Golden Poison Frog might be the most harmful South American animal，it also has poison frog neighborhood friends.In intense colors，they absolutely look appealing to capture and touch，but humans should stay far away from them. Piranha Despite the fact that only a small number of many kinds of piranhas are thought to be dangerous to humans，the red­bellied piranha is one of those.The myths show that a large group of piranhas can absolutely eat a herd of large animals crossing the river，leaving only bones.Piranhas live in the freshwater streams of South America，and they can smell blood from far away and launch attacks swiftly.It is reported that they are only dangerous to human beings if the water of the river becomes less or they are short of food.Take good care，though，in entering the waters.The piranha in reality is one of the most dangerous animals. 本文介紹了南美洲的三種最危險(xiǎn)的動(dòng)物。 5．What is special about the anaconda? A．It kills its victim quickly with its poison. B．It kills its victim with its strength. C．It kills its victim with its sharp teeth. D．It gets its victim trapped and frightens it. 解析：細(xì)節(jié)理解題。根據(jù)第一段．..it coils all over its target，increasing the pressure until eventually its victim dies可知，答案為B項(xiàng)。 答案：B 6．The underlined word“camouflage”in Paragraph 1 is the closest in meaning to“______”． A．move about to find food B．eat all kinds of animals C．make loud noise to threaten others D．hide itself by using the environment 解析：詞義猜測(cè)題。根據(jù)句中．..so that they look like their surroundings and swiftly draw back...可推斷，camouflage意為“偽裝”，故答案為D項(xiàng)。 答案：D 7．The author mentioned the death of the dogs in Paragraph 2 to show that______. A．the poison of the Golden Poison Frog is deadly B．it had nothing to do with the Golden Poison Frog
