10.---Why do you look so worried?
---My computer broke down and my essay _____ unfinished since.(  )
A.has been leftB.was leftC.had been leftD.has left

分析 --"你為什么看起來這么焦慮?"
--"我的電腦壞了,我的散文還沒有寫完呢."

解答 答案:A.
根據句末的since可知,此處表示過去的某一動作或行為一直持續到現在,所以用現在完成時,可排除B和C;又因為"essay"與"leave unfinished"是被動關系,故用現在完成時的被動語態,可排除D;故選A.

點評 對于時態的考查題要明白句子發生的具體時間以及不同時態的用法,然后分清主被動關系即可

14.If you are a fruit grower-or would like to become one-take advantage of Apple Day to see what's around.It's called Apple Day but in practice it's more like Apple Month.The day itself is on October 21,but since it has caught on,events now spread out over most of October around Britain.
Visiting an apple event is a good chance to see,and often taste,a wide variety of apples.To people who are used to the limited choice of apples such as Golden Delicious and Royal Gala in supermarkets,it can be quite an eye opener to see the range of classical apples still in existence,such as Decio which was grown by the Romans.Although it doesn't taste of anything special,it's still worth a try,as is the knobbly(多疙瘩的) Cat's Head which is more of a curiosity than anything else.
There are also varieties developed to suit specific local conditions.One of the very best varieties for eating quality is Orleans Reinette,but you'll need a warm,sheltered place with perfect soil to grow it,so it's a pipe dream for most apple lovers who fall for it.
At the events,you can meet expert growers and discuss which ones will best suit your conditions,and because these are family affairs,children are well catered for with apple-themed fun and games.
Apple Days are being held at all sorts of places with an interest in fruit,including stately gardens and commercial orchards(果園).If you want to have a real orchard experience,try visiting the National Fruit Collection at Brogdale,near Faversham in Kent.

8.What can people do at the apple events?D
A.Attend experts'lectures.
B.Visit fruit-loving families.
C.Plant fruit trees in an orchard.
D.Taste many kinds of apples.
9.What can we learn about Decio?C
A.It is a new variety.
B.It has a strange look.
C.It is rarely seen now.
D.It has a special taste.
10.What does the underlined phrase""a pipe dream""in Paragraph 3 mean?B
A.A practical idea.
B.A vain hope.
C.A brilliant plan.
D.A selfish desire.
11.What is the author's purpose in writing the text?B
A.To show how to grow apples.
B.To introduce an apple festival.
C.To help people select apples.
D.To promote apple research.
