不知道你所謂的直接跟從句是指的什么,there be句型后面要跟被修飾詞或先行詞及關(guān)系詞才能接從句.你給的例子省略了關(guān)系詞,屬于定語(yǔ)從句,應(yīng)該是There are two cargos that need to arrange bookings for them.通常情況下there be句型多接表語(yǔ)從句和定語(yǔ)從句.
“there be...”句型是存在句的常用基本結(jié)構(gòu),there在句中處于主語(yǔ)位置,起形式主語(yǔ)的作用,真正的主語(yǔ)是隨后的名詞詞組.其謂語(yǔ)動(dòng)詞通常是be的各種時(shí)、體等形式.如：
There is ice on the lake. 湖上有冰.
There were three students in the classroom then. 當(dāng)時(shí)教室有三個(gè)學(xué)生.
There has never been anybody like you. 從來(lái)還沒(méi)有像你這樣的人.
There will be snow on high ground.在高地上將會(huì)有雪.
除此之外, there be句型還有一些特殊的結(jié)構(gòu)：
1. there + 情態(tài)助動(dòng)詞 + be表示 “預(yù)見(jiàn)”、“可能”、“必然”或“過(guò)去習(xí)慣存在”等.如：
There might be some desserts if you wait a bit. 如果你等一會(huì)兒,可能會(huì)有甜點(diǎn).
There ought to have been someone on duty all the time. 本來(lái)應(yīng)該有人全天值班.
There shall be no more wars. 再也不會(huì)打仗了.
也可以用there + 某些半助動(dòng)詞 + be(很少使用完成體形式),如：be going to, be certain to, be sure to, be likely to, have to be等.
There is going to be a rain. 要下雨了.
There's likely to be an interview.可能會(huì)有一場(chǎng)面試.
There has to be a mistake. 必定有錯(cuò).
2. 在正式文體中,某些表示存在、發(fā)生、出現(xiàn)、坐落等意義的不及物動(dòng)詞也可以與there連用,如：appear, seem, come, remain, exist, live, stand, lie, arise, enter, follow, occur, rise, grow, happen, belong, arrive, fly, flash, sail, pass, run, spring up, emerge等.如：
There exist many ancient temples in the country. 那個(gè)國(guó)家有很多古老的寺廟.
There lies a small village in the mountain.山里有個(gè)小村子.
Once upon a time, there lived an old queer man in the city. 從前,城里住著個(gè)怪老頭.
There remains nothing more to be done. 沒(méi)有什么別的事可做了.
There followed the first world war. 接著就是第一次世界大戰(zhàn).
There flashed through his mind the image of a heroic fighter.他的頭腦中閃過(guò)英雄戰(zhàn)士的形象.
There sprang up a wild gale.突然刮起一陣狂風(fēng).
偶爾也能見(jiàn)到there后接及物動(dòng)詞：
There struck me a sudden idea. 突然我有了一個(gè)主意.
如果句中的地點(diǎn)狀語(yǔ)前移就可以省略there. 如：
Behind the house (there) is a small river.
3. there + 不定式 to be 或there + being形式,稱為非限定存在句,可以作主語(yǔ)、賓語(yǔ)、介詞補(bǔ)足成分.
1) 作主語(yǔ)
There being a railway station in the town is a great advantage. 鎮(zhèn)上有個(gè)火車(chē)站,真方便呀!
“there to be+NP”作主語(yǔ)時(shí),通常用for作引導(dǎo)詞:
For there to be a mistake in a computer's arithmetic is impossible. 計(jì)算機(jī)計(jì)算錯(cuò)誤是不可能的.
It was seldom for there to be no late comers. 新來(lái)者很少?zèng)]有遲到的.
2) 作賓語(yǔ)
The committee anticipated there being less debate in the second discussion. 委員會(huì)期望在第二次討論中爭(zhēng)議能少一些.
We expect there to be no objections. 我們希望不會(huì)有人反對(duì).
I'd prefer there to be more cooperation. 我希望有更多的合作.
3) 作介詞補(bǔ)足成分： 介詞是for, 用there to be形式； 介詞不是for,則用there being形式.
What's the chance of there being an election this year?今年進(jìn)行選舉的可能性有多大?
We have no objection to there being a meeting here. 在這兒舉行會(huì)議,我們不反對(duì).
Jill is waiting for there to be a big party.吉爾等著舉行一次盛大的晚會(huì).
此外,there + being形式還可以用作狀語(yǔ)分句,形成獨(dú)立主格結(jié)構(gòu)：
There being no further discussion, the chairman stood up and left the meeting-room.沒(méi)有可討論的了,主席站了起來(lái),離開(kāi)了會(huì)議室.
There having been no rain,the stream was dry. 一直沒(méi)有下雨,小溪都干涸了.
“there be...”句型的難點(diǎn)在于它的非限定形式, 怎樣分辨使用there to be 和there being 呢? 兩個(gè)要點(diǎn)是關(guān)鍵：它們?cè)诰渥又械某煞旨芭c句子中其他成分的搭配關(guān)系.如非限定形式的第2小點(diǎn)中的例句：anticipate與there being搭配,而expect 和prefer與there to be配伍.
