there are old tree roots to grab hold of. 這里為什么會(huì)連續(xù)出現(xiàn)grab.hold兩個(gè)動(dòng)詞?

C語(yǔ)言編程問(wèn)題 該程序是完成兩個(gè)數(shù)字的加減乘除 不知道為什么菜單項(xiàng)目會(huì)連續(xù)出現(xiàn)兩次。

getch()修改為

chargetch(void)
{
charc;
puts("Entertheoperationofyourchoice:");
puts("a.adds.subtract");
puts("m.multiplyd.divide");
puts("q.quit");
scanf("%c",&c);//%c前空格用于過(guò)濾上次輸入留在緩沖區(qū)的回車
returnc;
}

英語(yǔ)句子中會(huì)出現(xiàn)兩個(gè)連續(xù)的to嗎?

當(dāng)然可能了。 I went to see my doctor to make sure that I was better.(兩個(gè)不定式) He told the news to his father to make him happy. (第一個(gè)介詞,第二個(gè)不定式)

by 和on 的用法

介詞by可以用來(lái)表示方位、時(shí)間、手段等,其用法在高考中曾多次出現(xiàn)。下面結(jié)合高考試卷和其它一些例句做一下歸納: 一、by+地點(diǎn)名詞。表方位,意為:“在…旁邊”。如:by the lake/river/tree/window/door等。 She searched the top of the hill and stopped to rest on a big rock by the side of the path.(NMET90)她搜索了山頂,然后停下來(lái)在路邊的一塊大石頭上休息。 After supper she would sit down by the fire,sometimes for

高中英語(yǔ)語(yǔ)法:There is no limit..........(有兩種句型,一個(gè)是加to sth,還有一種是什么)

1. “more than one + 單數(shù)名詞”雖有復(fù)數(shù)概念,但習(xí)慣上用單數(shù)動(dòng)詞。 2. C.except that except可以跟從句。 except + 從句 He cannot hide his feelings, except when the waiters ask if everything is all right. 除了在服務(wù)生問(wèn)他是否覺(jué)得不舒服時(shí)之外,他無(wú)法掩藏自己的感覺(jué)。 (P24) 本句中含有介詞except + when引導(dǎo)的從句作狀語(yǔ),很多同學(xué)對(duì)此不理解,其實(shí)except除了接名詞、代詞、介詞短語(yǔ)、動(dòng)詞不定式外,還可接從句。如: 1. Everybody exc

it was planted where its tough roots which grow up to five feet long could help hold back the soil

分解各從句: A. it was planted (somewhere) 它被種植(在某處) B. its tough roots could help hold back the soil 它堅(jiān)韌的根能幫助它抓牢泥土 C. (its roots) grow up to five feet (它的根)長(zhǎng)到了五英尺 句法分析: ①A句為句子主干。主語(yǔ):it。謂語(yǔ):plant。地點(diǎn)狀語(yǔ):somewhere。 ②B句為A句的地點(diǎn)狀語(yǔ)從句,以where引導(dǎo)。主語(yǔ):its tough roots。謂語(yǔ):could help。這里的hold是過(guò)去分詞一般式 (done)作狀語(yǔ),修飾謂語(yǔ)動(dòng)詞,進(jìn)一步說(shuō)明謂語(yǔ)
