【題目】— Would you please tell us the prospect of fighting against COVID-19?

— We are sure to win the battle, but ______ it’ll be over soon I’m not sure at the moment.

A.whetherB.thatC.ifD.when

【答案】A

【解析】

考查名詞性從句連接詞。句意：——你能告訴我們抗擊新冠病毒的前景嗎？——我們確定能贏得這場戰(zhàn)爭，但它是否很快就會結束，我現(xiàn)在還不確定。根據(jù)句意，說話人不確定新冠疫情是否很快就會結束，故此處應選“是否”，故排除B、D兩項；引導賓語從句，強調賓語部分時，也可把從句放在句首，此時只用whether不用if。故選A。

It’s been a long vacation. Last month, my aunt and uncle returned work, so they needed someone to look after their child. I offered to give them the hand. I had thought I was able to do that but things turned out so differently.

First, they fought from time to time but I couldn't stop from it. Then, the mess they made really annoys me. At lunchtime, I was busy preparing food while screaming to stop them beating each other. I wished I have not made that crazy offer. To her great relief, my grandma came that afternoon, which meant that finally I was able to go home—after cleaning up the garbage everywhere and collected the toys on the floor. How a busy day!

【題目】 Compulsory citywide garbage sorting began in Beijing in April, aided by new guidelines for residents and the start of a three-month inspection campaign to monitor enforcement. The strict garbage sorting rules require residents to classify their domestic trash into four different categories: kitchen waste, recyclables, hazardous waste and other waste. 【1】

Communities and villages across the capital must set up four different colored trash bins. 【2】 To help residents better classify their domestic trash, four supporting measures would specify the management standards and implementation procedures for classifying garbage. For example, a guideline released in April advised residents to have two trash bins and one garbage bag at home to make the separation of different kinds of waste more convenient.

【3】 The inspection, lasting until the end of July, will focus on mixed waste and its dumping and transport. Meanwhile, the city's market supervision authorities will begin a three-month crackdown on the illegal use and sale of plastic bags.

Under the newly revised domestic waste regulation, supermarkets, shopping malls and trade markets may no longer use super thin or free plastic bags. 【4】

By the end of March, there were 44 domestic waste treatment facilities in Beijing, capable of handling 32,711 metric tons of trash a day, the capital's urban management authorities said. The capital collected 10.11 million tons of household waste last year.

Some residential communities in Beijing have introduced incentives（激勵）to encourage residents to sort their garbage. 【5】 Some communities had explored new ways of reusing kitchen waste as fertilizer for the residents' rooftop garden.

A.Law enforcement agencies will launch a three-month inspection to monitor compliance with compulsory trash sorting.

B.Those who fail to sort their garbage properly could face fines of up to 200 yuan （$28）.

C.The community acquired a trash treatment machine last year that can recycle some kitchen waste to produce organic soil in 24 hours as fertilizer for potted plants.

D.Restaurants and hotels must stop offering disposable items unless customers request them.

E.Residents can earn points by classifying their domestic waste correctly and then exchange the points they accumulate for daily necessities such as napkins and soap.

F.The treatment facility makes residents more familiar with the processing of garbage and spur their enthusiasm for trash sorting.

G.Green bins will be for kitchen waste, blue ones for recyclables, red for hazardous waste and gray for other waste.

【題目】 People often say that “failure is the mother of success”. 【1】 As a result, Manalo, a professor of educational psychology in Japan says, “We know we shouldn’t give up when we fail—but in reality, we do.”

Manalo and Manu, a professor of learning sciences in Swiss, put together a special issue (專利) last December on benefiting from failure. The issue’s 15 studies provide teachers and educational researchers with a guide for achieving success. 【2】 Another confirmed that advice on failures is most constructive when the receiver is prepared to experience unpleasant feelings.

Manalo and his co-authors also focused on overcoming one everyday form of failure: not completing a task. They asked 131 students to write an article about their school experiences. Half of the students received instructions for their writing, and half were left to their own. 【3】 Afterward the researchers found that those in the instructed group were more willing to complete their articles, compared with those who lacked guidance—even if the latter were closer to being done. 【4】

【5】 Stephanie Couch, the director of the Lemelson-MIT Program, holds the opinion. Couch, whose work was also featured in the special issue, says that we should tell them to think of failure as part of a process toward success.

A.However, all were stopped before finishing.

B.The saying shows the importance of success.

C.Teaching students not to fear failure makes goals achieved more easily.

D.One study reported that the sooner students fail, the sooner they can move forward.

E.Though having some truth to it, the saying does not tell us how to turn a loss into a win.

F.They believed that learning how to fail can help people avoid becoming lasting failures.

G.Knowing how to finish, in other words, was more important than being close to finishing.

【題目】 RAMCO TECHNOLOGIES

Where Technology Shapes Tomorrow

Marketing @Ramco.comewww.Ramco.com

TO: Rachel Mohler, Vice President

Harrison Fontentot, Public Relations

FROM: Mike Gonzalez

SUBJECT: Three Ways to Increase Ramco’s Community Involvement

DATE: March 5, 2019

At our planning session in early February, our division managers stressed the need to generate favourable publicity for our new Ramco facility in Mayfield. Knowing that such publicity will highlight Ramco’s visibility in Mayfield, I think the company’s image might be enhanced in the following three ways.

CREATE A SCHOLARSHIP FUND

Ramco would receive favourable publicity by creating a scholarship at Mayfield Community College for any student interested in a career in technology. A one-year scholarship would cost $6,800. The scholarship could be awarded by a committee composed of Ramco executives. Such a scholarship would emphasize Ramco’s enthusiastic support for the latest technical education at a local college.

OFFER SITE TOURS

Guided tours of the Mayfield facility would introduce the community to Ramco’s innovative technology. These tours might be organized for academic, community, and civic groups. Individuals would see the care we take in protecting the environment in our production and equipment choices and the speed with which we ship our products. Of special interest to visitors would be Ramco’s use of industrial robots working alongside our employees. Since these tours would be scheduled in advance, they should not conflict with our production schedules.

PROVIDE GUEST SPEAKERS

Many of our employees would be excellent guest speakers at civic and educational meetings in the Mayfield area. Possible topics include the advances Ramco has made in designing and engineering and how these advances have helped consumers and the local economy.

Thanks for giving me your comments as soon as possible. If we are going to put one or more of these suggestions into practice before the facility opens in mid-April, we’ll need to act before the end of the month.

【1】If Ramco establishes a scholarship, it will _____.

A.benefit students at colleges in Mayfield

B.highlight Ramco’s support for the latest technical advances

C.be offered to MCC students interested in a career in technology

D.be jointly awarded by Ramco executives and college professors

【2】Which of the following is true according to the passage?

A.Site tours of Mayfield facility can be arranged at any time.

B.The three measures are scheduled to be carried out in mid-April.

C.The three measures are sure to create favourable image for Mayfield.

D.Guest speakers will talk about Ramco’s advances in designing and engineering.

【3】What type of writing is this passage?

A.A letter of introduction.B.A letter of proposal.

C.A letter of recommendation.D.A letter of complaints.

【題目】 Americans have always been ambivalent in their attitudes toward education. On the one hand, free and universal public education was seen as necessary in a democracy, for how else would citizens learn how to govern themselves in a responsible way? On the other hand, America was always a country that offered financial opportunities for which education was not needed: on the road from rags to riches, schooling-beyond the basics of reading, writing, and arithmetic-was an unnecessary detour.

Even today, it is still possible for people to achieve financial success without much education, but the number of situations in which this is possible is decreasing. In today's more complex world, the opportunities for financial success is closely related to the need for education, especially higher education.

Our society is rapidly becoming one whose chief product is information, and dealing with this information requires more and more specialized education. In other words, we grow up learning more and more about fewer and fewer subjects.

In the future, this trend is likely to continue. Tomorrow's world will be even more complex than today's world, and, to manage this complexity, even more specialized education will be needed.

【1】The topic treated in this passage is _____.

A.education in generalB.Americans' attitudes

C.higher educationD.American education

【2】Americans' attitudes toward education have always been _____.

A.certainB.contradictoryC.ambitiousD.unclear

【3】Today, financial success is closely related to the need for _____.

A.higher educationB.public education

C.responsible citizensD.learning the basics

【4】It can be inferred from the third paragraph that _____.

A.information is our only productB.education in the future will be specialized

C.we are entering an age of informationD.we are living in an age of information

【5】Which of the following is the best title for the passage?

A.The History of American Education.B.The Need for Specialized Education.

C.The Future of the American Educational System.D.Attitudes toward American Education.
