12.She ______ called to say sorry to me,but my mobile phone was power-off all day long.(  )
A.needn't haveB.should haveC.could haveD.mustn't have

分析 她可能打電話想向我道歉,可我的手機(jī)一整天都關(guān)機(jī)了.

解答 答案:C 句意表達(dá)的是對(duì)過去的推測(cè);對(duì)過去的推測(cè)要用情態(tài)動(dòng)詞加完成時(shí)態(tài);needn't have done本不需要做某事,should have done本應(yīng)該做某事,D項(xiàng)是錯(cuò)誤搭配.故選C.

點(diǎn)評(píng) 情態(tài)動(dòng)詞的用法是英語中?嫉恼Z言點(diǎn).通常考查的方式有虛擬和推測(cè),本題考查的是情態(tài)動(dòng)詞的推測(cè)用法.學(xué)習(xí)時(shí)要注意積累.

Soon enough, we will lose some of the most amazing sites on Earth!

The Great Barrier Reef---Rising air temperatures will cause sea temperatures to rise as well. All life supported by the oceans will be affected with this shock to their ecosystem. Coral are some of the most vulnerable marine animals and we are already watching whole reefs disappear. The Great Barrier Reef in Australia is no exception and will continue to shrink as the temperatures rise! These reefs are some of the best in the world for diving, but they will soon disappear!

Venice---Sprawing across(橫跨)hundreds of small islands in Northeast Italy, Venice is at extreme risk of sinking into the Adriatic Sea. Rising sea levels are in fact a serious threat to many coastal cities located at sea level. Lucky for us, however, Venice is developing a series of sea walls to protect the city in times of high tide.

Glacier(冰川)National Park---Glacier National Park was once covered by over 150 glaciers, but by 2005 it only had about 27! Located in Montana, Canada, this park is over a million acres and has a huge plant and wildlife population. As temperatures rise, the glaciers and ice melt, which will upset the ecosystems sustaining over a thousand plant species and hundreds of animals.

The Amazon---The cause behind the disappearance of these fantastic places ultimately comes down to humans. Our expansion usually requires cutting down forests for land, fuel and materials, but rarely considers the consequences. These forests are sources of food and medicine for just about everyone on the planet!

What will happen if we lose these valuable places and beautiful destinations?!

1.According to the text, what is causing coral’s death?

A. Rising sea levels

B. Humans’ diving activities

C. Rising sea temperatures

D. The shrinkage(縮小)of their habitats

2.What can we infer from the part of “Venice”?

A. Venice is the only coastal city of Italy

B. Many places are in the risk of sinking below the sea level

C. Venice will never sink because of the protection of sea walls

D. Italy consists of hundreds of small islands in the Adriatic Sea

3.What can we learn about Glacier National Park from the text?

A. It covers a large area in Montana

B. It is covered by over 150 glaciers

C. Plant species and animals in it have died out

D. It doesn’t support any living thing for its cold

4.Which site’s shrinking reason differs from the other sites?

A. The Great Barrier Reef B. Venice

C. Glacier National Park D. The Amazon

17.閱讀下面的短文,然后按照要求寫一篇150詞左右的英語短文.
The purpose of a high school graduation ceremony is to celebrate students who have successfully met the academic and extracurricular requirements for graduation.The ceremony provides a public chance in which graduating students receive their diplomas(文憑),marking their official graduation from high school.High school graduation ceremonies are typically held at the end of the academic year and are attended by teaching staff,graduates and their families and friends.
