20、rch party went into the cave hoping to find buried treasure 可以推測只有 a. gold 是探寶隊(duì)所尋找的東西。 b. gold mine (金礦)； c. pirates (海盜)； d. a tin trunk (一個鐵皮箱)這3個選擇都與課文的實(shí)際內(nèi) 容不符，所以選a.a 根據(jù)課文第7-8行a search party 2. a 根據(jù)課文最后一句In spite of this, many people are confident that The revealer may reveal something of value f

21、airly soon 可以判斷只有a. works very well能夠說明“探寶器的性能如何,而其他3個選擇都與課文內(nèi)容不符合.2. a 根據(jù)課文最后一句In spite of th3. b 只有b. detecting (探測)最符合語法，因?yàn)榻樵~for 后面只能跟名詞或者動名詞，其他3個選擇都不能用在介詞后面，所以選b.3. b 只有b. detecting (探測)最符合4. d 前半句中的used to 表示過去常做某事，而現(xiàn)在已經(jīng)不做了，只有d. thats what hey would do (那就是他們過去經(jīng)常做的)同前半句意思想吻合。 因?yàn)閣ould 同used to 一樣

22、也可以表示過去經(jīng)常性的動作。 其他3個選擇都表示現(xiàn)在還在做，不合乎邏輯。4. d 前半句中的used to 表示過去常做某事，5. a 只有a. would find 是對的，因?yàn)榍耙痪銽hey hoped to find.就等于They hoped they would find.。其他3個選擇都與前一句的時態(tài)不符合，所以選a.5. a 只有a. would find 是對的，因?yàn)?. a 該句是一般過去時疑問句，因?yàn)樗呀?jīng)有助動詞did 提問了，所以謂語動詞要用原形。 只有a. dig 是動詞原形，其他3個選擇都不是動詞原形，所以選a.6. a 該句是一般過去時疑問句，因?yàn)樗呀?jīng)有助動詞d

23、7. c 本句的疑問詞How 是對主語the hole 的狀態(tài)或性質(zhì)提問的,因此它后面要跟形容詞. 只有c. deep是形容詞,表示深的,可以修飾名詞hole. 其他3個選擇 a. deeply(深深地)詞性不對; b. depth(深)是名詞,詞性也不對; d. down(向下)詞性和詞意思都不對,所以只能選c.7. c 本句的疑問詞How 是對主語the hole8. a 該句的主語Revealer (探寶器)是一種機(jī)器。 a. machine (機(jī)器)；b. engine (發(fā)動機(jī)，火車的機(jī)車)；c. machinery (機(jī)器總稱)是不可數(shù)名詞；d. mechanic (技工，機(jī)修工)，這4個選擇中只有a. machine 可以是Revealer 的定義，所以只能選a.8. a 該句的主語Revealer (探寶器)是一種9. b
