　　B　本題考查的是lie有關(guān)時(shí)態(tài)詞形的變化和語(yǔ)義辨析。在處理這一問(wèn)題時(shí)，首先我們要搞清楚它在語(yǔ)境中的語(yǔ)義，本句的語(yǔ)義是：經(jīng)理穿著衣服就在他躺著的地方睡著了。通過(guò)had fallen asleep可知它是“躺臥”的意思，排除A和C。從時(shí)態(tài)意義出發(fā)，睡著時(shí)，躺臥的動(dòng)作正在發(fā)生，所以答案是B。

　　()(2) At the foot of the hill ______ a big lake surrounded by trees.

　　A. lays

　　B. is laying

　　C. lies

　　D. lying

　　C　本題考查的是lie有關(guān)詞形的變化和語(yǔ)義辨析。在處理這一問(wèn)題時(shí)，我們首先要搞清楚它的句式結(jié)構(gòu)。這是地點(diǎn)狀語(yǔ)放在句首的一個(gè)完全倒裝句，其主語(yǔ)是 a big lake。它的語(yǔ)義是：山腳下有個(gè)被樹(shù)環(huán)繞著的大湖。

　　巧記一：

　　撒謊(lie)的規(guī)則，不規(guī)則的是躺 (lie)，躺下來(lái) (lay) 就下蛋 (lay), 下蛋 (laid) 不規(guī)則。

　　詞性 語(yǔ)義 過(guò)去式 過(guò)去分詞 現(xiàn)在分詞

　　lie vt.

　　撒謊 lied lied lying

　　vi. 躺臥 lay lain

　　lay vt. 產(chǎn)卵、下蛋；擺放 laid laid laying

　　巧記二：

　　(1)After struggling, he won in the end.

　　(2) They worked hard together and won the game.

　　(3)After ten years of hard work, he won the first prize for the music competition.

　　win out 獲勝；成功

　　win over 說(shuō)服；把……爭(zhēng)取過(guò)來(lái)

　　win the day 獲勝；成功

　　win/beat/defeat

　　win 是不及物動(dòng)詞，也是及物動(dòng)詞。在作為及物動(dòng)詞時(shí)，它的賓語(yǔ)不能是人。

　　Slow and steady wins the race.

　　beat 是及物動(dòng)詞，它的賓語(yǔ)是人，不能是事物。一般指小型的活動(dòng)。

　　We beat Class 1 in the school sports meeting.

　　defeat 也是及物動(dòng)詞，它的賓語(yǔ)是人，也可以是辯論活動(dòng)。比較正式，一般指大型活動(dòng)。

　　We will defeat them in the Olympic Games.

　　完成句子

　　(1) Our teachers have won the love and respect (贏得了愛(ài)戴和尊重)of the students.

　　單項(xiàng)填空

　　()(2) The Huston Rockets ______ the Los Angeles Lakers 108：89 in the NBA on Sunday.

　　A. hit

　　B. won

　　C. beat

　　D. defeat

　　C　句意：在周日的NBA比賽中，休斯敦火箭隊(duì)以108：89戰(zhàn)勝了洛杉磯湖人隊(duì)。hit“打、撞擊”明顯不合題意；win后不能跟人，這里的洛杉磯湖人隊(duì)指的是人；而beat和defeat可以，但從時(shí)態(tài)考慮，這件事發(fā)生在過(guò)去，要用一般過(guò)去時(shí)，beat 的過(guò)去式和原形是一致的，defeat的過(guò)去式是defeated，所以答案是C。
