2.run out
講：該短語(yǔ)為不及物動(dòng)詞，意思為“用完；用光”。

our food soon ran out.
我們的食物很快就吃完了。

我們快沒(méi)有時(shí)間了。
鏈接•拓展
(1)比較:run out 和run out of的區(qū)別。run out of為及物動(dòng)詞短語(yǔ)，run out為不及物動(dòng)詞短語(yǔ)，在使用時(shí)要注意動(dòng)詞的語(yǔ)態(tài)。
(2) run構(gòu)成的短語(yǔ)還有run into撞上；run across不期而遇。
his car ran into the tree.
他的汽車撞到了樹(shù)上。
i ran across an old friend in the street.
我在街上和一位老朋友不期而遇。
練: _________his food_________ ,the man had to come out of his hiding place.
a.since;run out of b.because;run out
c.with;running out d.with;run out of
提示:a、b兩個(gè)選項(xiàng)的時(shí)態(tài)不正確，應(yīng)該使用先于had to發(fā)生的過(guò)去完成時(shí)。with+n.+doing表示“隨著……”。
答案:c
句型
1.it is well known that...
講:注意觀察下面教材原句:
it is well known that africa had contacts with india and the red sea civilisations from the earliest times.
眾所周知，非洲從早時(shí)開(kāi)始，就已經(jīng)同印度和紅海文明有過(guò)接觸。
it is well known that...表示“眾所周知”，其中it為形式主語(yǔ)，that引導(dǎo)的從句是真正的主語(yǔ)。
例:it is well known that the earth is round.
as we know,the earth is round.
as is known(to us all),the earth is round.
眾所周知，地球是圓的。
it is well-known that edison invented the electric lamp.
眾所周知，是愛(ài)迪生發(fā)明的電燈。
鏈接•提示
注意比較該句型和“as we know, +主句”及“as is known, +主句”的區(qū)別，三個(gè)句型表示的意思是一樣的，但是結(jié)構(gòu)不同。it is known that...為主語(yǔ)從句形式，后面用that引導(dǎo)真正的主語(yǔ)；而as引導(dǎo)的是從句，后面使用逗號(hào)，然后跟主句。
練: _________it takes years of practice to gain the skills of an expert.
a.as is known that b.it is known to us that
c.as we know that d.it is known to us
提示:本題主要考查了表示“眾所周知”的幾個(gè)句型結(jié)構(gòu)上的不同。
答案:b
2.v.ing形式作伴隨狀語(yǔ)
講:請(qǐng)注意觀察下面教材原句:
