【題目】I know ________ boy with cool glasses. He is a top student in our school.

A.aB.theC.anD./

【答案】B

【解析】

句意：我認(rèn)識(shí)那個(gè)戴著很酷眼鏡的男孩。他是我們學(xué)校的尖子生。

考查冠詞。冠詞分為不定冠詞"a，an"、定冠詞"the"和零冠詞"(/)"三種，零冠詞指的是不用冠詞的情況。不定冠詞（a、an）表示泛指、類(lèi)指，僅用在單數(shù)可數(shù)名詞前來(lái)表示"一"的意義，但不強(qiáng)調(diào)數(shù)目概念，只表示名詞為不特定者，a用于輔音音素開(kāi)頭的可數(shù)名詞單數(shù)前，an用于元音音素開(kāi)頭的可數(shù)名詞單數(shù)前。定冠詞the，表示特指、專(zhuān)指，表示名詞的特定者，表示"這"、"那"、"這些"、"那些"，用在可數(shù)名詞單數(shù)、復(fù)數(shù)，不可數(shù)名詞前均可。復(fù)數(shù)可數(shù)名詞和不可數(shù)名詞前不用冠詞（使用零冠詞），表示泛指人或事物。本句表示特指，特指“那個(gè)戴著很酷眼鏡的男孩”，可知使用定冠詞the；故選B。

科目：初中英語(yǔ) 來(lái)源： 題型：

【題目】 Today there are more fires than in the past. Over 100,000 wildfires burn each year in America. Russia has 20,000 to 35,000 wildfires every year. Australia has on average 60,000 each year. These fires destroy huge areas of forests and burn hundreds of homes.

Many experts believe _______. The first is climate change. Recent weather has been warmer and drier. This leads to dangerous fire conditions. When lightening strikes, dry grass easily catches fire. Hot winds add to the problem. The wind spreads a fire quickly. In 2010, Russia had the hottest and driest summer in a century. In just one month, 500 fires destroyed over 2,000 homes. Some people lost their lives.

Traditional fire-fighting practices are another reason for the increase in fires. In America, firefighters used to quickly put out every fire. They didn't allow the grass and trees to burn. As a result, today many forests have thicker vegetation(植被). Thicker vegetation means more fuel for fires. also, without fires from time to time, forests become overcrowded and unhealthy. Some trees are dead. The dead wood then easily catches fire. So surprisingly, America has many more fires today partly because of its past fire-fighting practices.

Scientists now understand that a fire can be a natural part of healthy forest. As a result, countries like Australia allow more fires to burn naturally. Sometimes, fire fighters even start fires to get rid of dead wood. Of course, they carefully control the fires. The fire thins out old trees. This allows sunlight to reach the ground. As a result, fires help new trees to grow. Therefore, if a fire is not a serious threat to people, firefighters may let it burn naturally.

【1】Today _______ has the most wildfires each year according to the passage.

A.AustraliaB.AmericaC.RussiaD.China

【2】Russia had many fires in one month in 2010 because _______.

A.lightening spread the fireB.there was much fuel for fires

【3】What can be filled in the blank in Paragraph 2?

A.there are several reasons for this sudden increase in fires

B.people have done too many terrible things in recent years

C.stopping fires is difficult for people

D.careless people cause some fires

【4】Because of the traditional fire-fighting practices in the US, _______.

A.there are fewer wildfiresB.trees and grass become thicker

C.the weather becomes warmer and drierD.sunlight reaches the ground to help forests

【5】What is the main idea of Paragraph 4?

A.Fires are serious threats to human beings.

B.Australian firefighters don't put out fires.

C.Fires can play an important role in forests.

D.It's difficult for firefighters to control the fires.

【6】Which of the following is TRUE according to passage?

A.Not all the fires in the forests must be put out.

B.People's carelessness leads to dangerous fires.

C.Australia allows all the fires to burn naturally.

D.There are 2000 fires in Russia in 2010.
