實驗3 英文指法練習
問題描述
只有熟練地掌握鍵盤分區(qū)及鍵位分布、了解鍵盤打字的標準指法,才能逐步實現(xiàn)用盲打的方式輸入英文,下面來學習鍵盤輸入的基礎知識及一些基準鍵的輸入。
解決方案
1.鍵盤輸入的基礎知識
(1)鍵盤輸入的要求。
擊鍵時腰背挺直,雙肩放松,手腕平直不可上下彎曲,更不能將手腕放在鍵盤上。雙手按基準鍵位時要求將手指自然彎曲地輕放在鍵位上。擊鍵時通過手指關節(jié)活動的力量叩向鍵位,而不是用肘和腕的力量。每次擊鍵完成后,手指始終都要保持在基準鍵位上,以便下一次擊鍵。如圖1-2所示。

圖1-2 手指對應的鍵盤按鍵
(2)基準鍵位。
凡處于打字準備狀態(tài)時,雙手放在A、S、D、F、J、K、L、“;”鍵上,這8個鍵稱為基準鍵位。其中,F(xiàn)、J鍵稱為定位鍵(鍵帽上有一小橫杠),其作用是將左右食指分別放在F和J鍵上,其余三指依次放下就能找到基準鍵位。基準鍵位的分布及手指分工,如圖1-3所示。

圖1-3 基準鍵位分布及手指分工
(3)字母鍵指法分區(qū)。
字母鍵指法分區(qū),如圖1-4所示。凡兩斜線范圍內的字母鍵,都必須由規(guī)定的手指管理。這樣一來,既便于操作,又便于記憶。

圖1-4 字母鍵指法分區(qū)示意圖
其中:
左小拇指負責擊打如下鍵:1,Q,A,Z,Shift。
左無名指負責擊打如下鍵:2,W,S,X。
左中指負責擊打如下鍵:3,E,D,C。
左食指負責擊打如下鍵:4,R,F(xiàn),V。
5,T,G,B。
右食指負責擊打如下鍵:6,Y,H,N,
7,U,J,M。
右中指負責擊打如下鍵:8,I,K,“,”。
右無名指負責擊打如下鍵:9,O,L“。”
右小拇指負責擊打如下鍵:0,P,;,“/”,Shift,Enter。
兩個大拇指負責擊打空格鍵。
前面講了8個基準鍵位與手指的對應關系,必須牢牢記住。在基準鍵位的基礎上,對于其他字母、數(shù)字、符號都采用與8個基準鍵位相對應的位置來記憶。
2.基準鍵的練習
基準鍵也稱原位鍵,是打字時手指應保持的固定位置,擊打其他鍵都是以基準鍵來定位的。在進行基準鍵練習時,手指擊鍵后仍放在原位字鍵上。
輸入以下字符,反復練習擊打基準鍵。
add add add add all all all all dad dad dad dad
ask ask ask ask sad sad sad sad fall fall fall fall
add all dad ask fall alas flask add ask lad sad fall
3.I、E鍵的練習
這兩個鍵分別由左手中指和右手中指彈擊,擊鍵時,手指從基準鍵出發(fā),擊完后手指立即回到基準鍵位上。同時注意其他手指不要離開基準鍵,小拇指不要翹起。
輸入以下字符,反復練習擊打I、E鍵。
fed fed fed fed eik eik eik eik lid lid lid lid
desk desk desk desk jade jade jade jade less less
said said said said leaf leaf leaf leaf fade fade
4.G、H鍵的練習
這兩個鍵在8個基準鍵中央,分別由左手食指向右伸出一個鍵位的距離、右手食指向左伸出一個鍵位的距離擊出,擊完后手指立即回到基準鍵位。
輸入以下字符,反復練習擊打G、H鍵。
gall gall gall gall fhss fhss fhss fhss fhgl fhgl
hasd hasd hasd hasd sgds sgds sgds sgds hkga hkga
glad glad glad glad half half half half shds shds
5.R、T、U、Y鍵的練習
這四個鍵分別由左手食指和右手食指(各自負責兩個字母鍵)彈擊,開始速度不宜快,體會食指微偏左向前伸和微偏右向前伸所移動的距離和角度,擊完后手指立即回到基準鍵位。
輸入以下字符,反復練習擊打R、T、U、Y鍵。
gart gart gart gart fuss fuss fuss fuss furl furl
hard hard hard hard suds suds suds suds lurk lurk
rual rual rual rual adult adult adult adult altar
6.W、Q、O、P鍵的練習
這四個鍵分別由左手及右手的無名指、小拇指彈擊,注意小拇指擊鍵準確度差,應反復練習小拇指擊鍵和回位的動作。
輸入以下字符,反復練習擊打W、Q、O、P鍵。
ford ford ford ford blow blow blow blow spqg spqg
cout cout cout cout swle swle swle swle quest quest
ough ough ough ough toward toward toward toward
7.V、B、M、N鍵的練習
這四個鍵分別由左右手的食指(各自負責兩個字母鍵)彈擊,注意體會食指移動的距離和角度,擊完后手指立即回到基準鍵。
輸入以下字符,反復練習擊打V、B、M、N鍵。
vest vest vest vest time time time time alms alms
verb verb verb verb mine mine mine mine value value
8.C、X、Z鍵的練習
用左手中指、無名指、小拇指分別彈擊C、X、Y鍵,手指向手心方向微偏右屈伸,擊完后手指立即回到基準鍵。
輸入以下字符,反復練習C、X、Y鍵的操作。
rich rich rich rich text text text text xrox xrox
quch quch quch quch xfar xfar xfar xfar zbet zbet
exec exec exec exec frenzy frenzy frenzy frenzy
9.主鍵盤區(qū)數(shù)字鍵的練習
數(shù)字鍵離基準鍵較遠,彈擊時必須遵守以基準鍵為中心的原則,依靠左右手的敏銳度和準確的鍵位感,來衡量數(shù)字鍵與基本鍵的距離和方位。
彈擊1鍵時,左手小拇指向上偏左移動,越過Q鍵;依照前一動作,用左手無名指彈擊2鍵,用左手中指彈擊3鍵。
彈擊4鍵時,左手食指向上偏左移動,越過R鍵;彈擊5鍵時,左手食指向上偏右移動。
彈擊6鍵時,右手食指大幅度向左上方伸展,越過Y鍵;彈擊7鍵時,右手食指向上偏左移動,越過U鍵。
彈擊8鍵時,右手中指向上偏左移動,越過I鍵;依照前一動作,用右手無名指彈擊9鍵,用右手小拇指彈擊0鍵。
輸入以下字符,反復練習擊打數(shù)字鍵。12343456239898076436 12.4 3.56 87.9 34.9 5.78
a12 ab3 s2d 345123 789907 1ST 2Nd 3RD 4TH 5TH
JANUARY 151994 May 51994 BUS NO.6 ROOM 567
10.常用鍵和符號鍵的練習
(1)空格鍵。
空格鍵在鍵盤的最下方,它由大拇指控制。擊鍵的方法是右手從基準鍵位垂直上抬1~2cm,大拇指橫著向下?lián)舸蚩崭矜I,擊鍵完畢立即縮回。
(2)Enter鍵。
Enter鍵應該由右手的小拇指來控制。擊鍵方法是抬右手,伸小拇指彈擊Enter鍵,擊鍵完畢立即回到基準鍵位。
(3)Shift鍵。
Shift鍵的作用是用于控制換檔。在鍵盤上,如果一個鍵位上有兩個字符,那么當需要輸入上檔字符時就必須先按住Shift鍵,再彈擊上檔字符所在的鍵。
Shift鍵是由小拇指控制的。為使操作起來方便,鍵盤的左右兩端均設有一個Shift鍵。如果待輸入的字符是由左手控制的,那么事先必須用右手的小拇指按住Shift鍵,再用左手的相應指頭彈擊上檔字符鍵;如果待輸入的字符是右手控制的字鍵,那么事先必須用左手的小拇指按住Shift鍵,再用右手的相應的指頭彈擊上檔字符鍵。只有上檔字符鍵完畢后左右手的指頭才能縮回到基準鍵位上。
(4)符號鍵。
鍵盤上還有其他一些字符,如“+”、“-”、“*”、“/”、“(”、“)”、“#”、“!”、“@”、“?”、“&”、“:”、“$”、“%”等。這些字符的輸入也必須按照它們各自的指法分區(qū),用相應的手指按規(guī)則輸入。只要我們熟悉了Shift鍵的擊鍵原則和方法,那么這些字符的輸入是不難掌握的。
輸入以下字符,反復練習擊打符號鍵。
+++++ ***** ----- ()()()()() #####
!!!!! $$$$$ &&&&& ?????
11.綜合練習
用操作系統(tǒng)提供的“記事本”程序進行指法練習:
A visiting senior Chinese diplomat said here Thursday that China had done a great deal in order to solve the Darfur issue.
“Chinese government has done a great deal in order to solve the Darfur issue.” Liu Guijin, special representative of the Chinese government on the Darfur issue, said at a news conference at the Chinese Embassy in London.
Chinese President Hu Jintao had met the Sudanese President Omeral-Bashir twice during a trip to Sudan last February and the Beijing Summit of China-Africa Cooperation Forum in 2006, said Liu, who is a former ambassador to Zimbabwe and South Africa, and has been engaged in African affairs for more than 25 years.
“Because of the efforts made by the international community, and by the Chinese government, the Sudanese government has accepted the deployment of the hybrid peacekeeping forces in Darfur and the UN security council has adopted the resolution 1769,which has put the Darfur issue on a road of political settlement.” said Liu.
China has pledged to send a 315-member multi-functional engineering unit to the region, and 140 members have arrived and carried out effective work in building camps, wells, roads for the hybrid operation, said Liu, adding that the rest 175 were preparing to go there soon.
Liu also detailed on China's humanitarian assistance in the Darfur region.
China provided assistance of about 11 million U.S. dollars in five batches, and provided Sudan with power generators, pumps and 120 schools, he said.
China has already helped the Sudanese dig 46 wells and build 20power plants to ease the severe water shortage in the country, which is one of the major causes for turmoil in the Darfur region. And Chinese companies have spent 50 million U.S. dollars in building 85 km of water pipelines and digging wells in southern Darfur, which will be completed in months.
Moreover, china will provide another 90 million U.S. dollars in soft loan for the construction of water supply facilities in northern Darfur.
Liu said that china will do more for the Sudanese, and hoped that other countries would do“tangible and practical work” to help relieve the sufferings in the Darfur region.
China was the first nation outside Africa to send peacekeepers to Darfur and the first and biggest development aid provider to the region.
提示
在輸入英文字母時,F(xiàn)、J鍵稱為定位鍵(鍵帽上有一小橫杠),其作用是將左右食指分別放在F和J鍵上,眼睛不要盯著鍵盤。
