【題目】閱讀下面短文,在空白處填入1個(gè)適當(dāng)?shù)膯卧~或括號(hào)內(nèi)單詞的正確形式。
Dogs were first raised at home at least 150 centuries ago. Since then, the dog 【1】(be) humans’ best friend. Now, they have another job—to help doctors to diagnose(診斷)cancer.
After a long-standing research of smell, a Finnish professor has said that certain 【2】(type) of cancer are able to be discovered by their smell, 【3】(make) it possible to train cancer-sniffing dogs to help diagnose the disease.
A professor, JoukoVepsalainen from the University of Eastern Finland in Kuopio, has focused on nitrogen compounds(氮化合物). The compounds increase 【4】 (great) when cancer cells grow in an uncontrollable way, allowing them 【5】(find) out, the Finnish newspaper Karjalainen reported. That’s where the dog, man’s best friend, may step in with their sharp sense of smell.
According 【6】 the news agency, researchers in Finland have tried to train dogs to do the job, but 【7】 will take a dog months, even years, to tell the 【8】(different) between sick and healthy people. “Anyone 【9】knows how difficult early cancer detection(察覺(jué)) is understands what 【10】good opportunity this is,” associate professor Anna Hielm-Bjorkman of the University of Helsinki told the Finnish media.
【答案】
【1】has been
【2】types
【3】making
【4】greatly
【5】to be found
【6】to
【7】it
【8】difference/ differences
【9】who
【10】a
【解析】
這是一篇說(shuō)明文。文章主要介紹了某種癌癥可以通過(guò)氣味來(lái)檢測(cè),這使得訓(xùn)練嗅癌犬幫助診斷癌癥成為了可能。
【1】
考查時(shí)態(tài)。結(jié)合上文出現(xiàn)“since then”可知,該句應(yīng)使用現(xiàn)在完成時(shí),主語(yǔ)為“the dog”是單數(shù)第三人稱(chēng)形式,故填has been。
【2】
考查名詞的數(shù)。分析該句可知“certain ___2___(type) of cancer”為從句的主語(yǔ),其后謂語(yǔ)為“are”,推出該句主語(yǔ)應(yīng)該為復(fù)數(shù)形式,故填types。
【3】
考查非謂語(yǔ)動(dòng)詞。此處非謂語(yǔ)動(dòng)詞作狀語(yǔ),make與其邏輯主語(yǔ)“certain ___2___(type) of cancer ”構(gòu)成主謂關(guān)系,故用現(xiàn)在分詞形式。故填making。
【4】
考查副詞。此處使用副詞greatly來(lái)修飾其前動(dòng)詞increase。故填greatly。
【5】
考查不定式。結(jié)合短語(yǔ)allow… to do sth譯為“允許……做”可知此處填不定式,同時(shí),find out與邏輯主語(yǔ)“them”之間構(gòu)成被動(dòng)語(yǔ)態(tài),故用不定式的被動(dòng)形式,故填to be found。
【6】
考查固定搭配。此處考查according to譯為“根據(jù)”,為固定短語(yǔ)。故填to。
【7】
考查it用法。此處考查it takes sb time to do sth譯為“花費(fèi)某人多長(zhǎng)時(shí)間去做某事”,該句中不定式為真正的主語(yǔ),而it為形式主語(yǔ)。故填it。
【8】
考查名詞。此處應(yīng)填名詞作tell的賓語(yǔ),故將different(adj)變成其名詞形式difference,結(jié)合語(yǔ)境,此處可以特指一個(gè)或多個(gè)不同。故填difference\differences。
【9】
考查定語(yǔ)從句。分析該句為定語(yǔ)從句,其先行詞為anyone,在從句中做主語(yǔ),故用關(guān)系代詞who來(lái)引導(dǎo)。故填who。
【10】
考查不定冠詞。句意:任何知道早期癌癥檢測(cè)有多么困難的人都知道這是一個(gè)多么好的機(jī)會(huì)。該句為what引導(dǎo)的感嘆句結(jié)構(gòu):what+不定冠詞+形容詞+單數(shù)名詞+主+謂,本句中不定冠詞后為good opportunity,故使用不定冠詞“a”,故填a。

While thousands of college students headed for warm climate to enjoy sun and fun during their week off from classes, seven local students had other plans.
The Northern Essex Community College (NECC) students and one of their teachers spent part of their spring break in New York City, helping repair an area 【1】 (destroy) by the hurricane. “I wanted to see for myself what happened,” said Terry. “I couldn’t imagine【2】it is like to lose your home and everything that you know and the【3】(power) effect the hurricane had on those people. I wanted to do something, to understand their feeling of helplessness.” The group headed into Brooklyn’s Red Hook district, which was hit hard by the hurricane. There they met people from other parts of the country, 【4】had also volunteered to help. Together, those volunteers and the NECC students worked 【5】 (clear) rubbish out of a three-story building.

科目:高中英語(yǔ) 來(lái)源: 題型:
【題目】 Most adults find it hard to recall events from their first few years of life and now scientists have found exactly when these childhood memories fade(消失).
A new study has found that most three-year-olds can recall a lot of what happened to them over a year earlier, and these memories persist while they are five and six, but by the time they are over seven, these memories decline(衰退) rapidly.
Most children by the age of eight or nine can only recall 35% of their experiences from under the age of three, according to the new findings.
The scientists behind the research say this is because at around this age the way we form memories begins to change. They say that before the age of seven children do not have a sense of time and place in their memories. In older children, however, the early events they can recall tend to be more adult-like in the way they are formed. Children also have a far faster rate of forgetting than adults. The findings also help to explain why children can often have clear memories of events but then forget them just a couple of years later.
The youngsters first visited the laboratory at the age of three and discussed six unique events from their past, such as family outings, trips to the zoo, and the first day of school. The children then returned for a second session between the ages of five and nine to discuss the same events. The researchers found that between the ages of five and seven, the amount of memories the children could recall remained between 63 -72 percent. However, the amount of information eight-to nine-year-old children could recall dropped to 35 and 36 percent.
【1】What does the new study tell us?
A.Childhood memories decline with years.
B.Three-year-old kids are the cleverest.
C.Childhood memories can fade easily.
D.Some adults cannot recall past events.
【2】What does the underlined word “persist” in Paragraph 2 mean?
A.Change.B.Remain.
C.Appear.D.Return.
【3】What can we learn from Paragraph 4?
A.Adults cannot have clear memories of past events.
B.Children can think like adults when they get older.
C.Children under 7 years old have different ways of forming memories.
D.Children often forget things because they have no idea of time or place.
【4】In the second session, nine-year-old children _________.
A.refused to discuss the same events
B.remembered all their family outings
C.could recall 72 percent of their past events
D.only remembered a small part of their past events
