【題目】A survey carried out last year showed that 80% of the middle-aged in this city ____________ in favour of the proposal on health care reform.

A.isB.areC.wasD.were

【答案】D

【解析】

考查動(dòng)詞時(shí)態(tài)和主謂一致。句意：去年進(jìn)行的一項(xiàng)調(diào)查顯示，該市80％的中年人贊成醫(yī)療改革的建議。通過(guò)分析句子結(jié)構(gòu)并翻譯語(yǔ)境可知，主句時(shí)態(tài)為一般過(guò)去時(shí)，根據(jù)時(shí)態(tài)一致性可知從句中時(shí)態(tài)也為一般過(guò)去時(shí)，且從句中主語(yǔ)80% of the middle-aged是復(fù)數(shù)，按照主謂一致原則，因此使用be動(dòng)詞were。故選D項(xiàng)。

【題目】 Commuters of the future could get some relief from congested roads especially the peak-hour traffic if Uber’s plans for flying taxis work out.

The battery-powered aircraft looks like a cross between a small plane and a helicopter, with fixed wings and rotors (旋轉(zhuǎn)器). It was presented at an international technology conference in Lisbon, Portugal.

Catering for the need of shorter city travel time, the vehicle is intended to soar over traffic congestion. Uber hopes it will eventually become a form of convenient mass transport and cost commuters aboard less than using their own car, though initially it will be more expensive than that, Uber’s Chief Product Officer Jeff Holden said.

The scheme still faces plenty of challenges, including certification of the new vehicle by authorities, pilot training and constructing urban air traffic management systems that prevent collisions.

Holden declared that Uber is joining NASA’s project to expand air traffic systems, which scores of other companies already belong to.

He told The Associated Press in an interview that he has no dollar figure for the total investment. He said Uber is putting some of its own money into the project, developing software, while other investors are also involved, such as aircraft manufacturers that are developing the vehicle and real estate companies that are providing so-called “skyports” where people will catch their airborne taxi.

Uber is making a bid to reform and polish up its image which has been damaged by certain negative news. Holden said those episodes did not slow development of the flying taxi project of the great company that is in transition.

【1】What result is Uber’s flying taxis aimed to achieve?

A.Shorter city travel time.B.Smooth flow of traffic.

C.Higher economic efficiency.D.Convenience of people’s life.

【2】Which of the statement is correct according to Holden?

A.Flying taxis are more cost-effective than driving private cars.

B.Uber has to cooperate with NASA to reach it’s goal.

C.The success of this project, if possible, will polish up Uber’s image.

D.The final achievement of Uber’s goal relies not only on the company itself.

【3】What does the underlined word “episodes” in the paragraph probably mean?

A.troubleB.exchange

C.incidentD.process

【4】What is implied in the last paragraph?

A.Uber is committed to developing the flying taxi project.

B.Uber is to accomplish it’s transition period in the near future.

C.Uber’s reputation used to be ruined by rumors.

D.Uber has recovered from it’s damaged image.

【題目】根據(jù)短文內(nèi)容，填寫(xiě)表格。

A great many parents send their children to pre-schools - educational programs for children under the age of five. It has been said that this is the time period when the brain does over fifty percent of its growing. This could mean that the learning process should be introduced during these years.

However, the views that different societies hold regarding the purpose of early childhood education are not same. Whereas Chinese parents tend to see preschools primarily as a way of giving children a good start academically, parents in the United States regard the primary purpose of preschools as making children more independent and self-reliant.

Preschools can operate under a guiding philosophy of play-based or academic learning. Play-based programs are guided by the central belief that children learn best through play. Play is thought to build children’s interest and love of learning. Academic programs emphasize reading, math and science, and use structured, teacher-directed activities to promote foundational skills in these areas. In the United States, the best-known program designed to promote future academic success is Head Start. The program, which stresses parental involvement, was designed to serve the “whole child”, including children’s physical health, self-confidence, social responsibility, and social and emotional development.

A recent evaluation suggests that preschoolers who participate in Head Start are less likely to repeat grades, and more likely to complete school in future. Furthermore, graduates of Head Start programs show higher academic performance at the end of high school, although the gains are modest. In addition, results from other types of preschool readiness programs indicate that for every dollar spent on the program, taxpayers saved seven dollars by the time the graduates reached the age of 27.

Not everyone agrees that programs that seek to enhance academic skills during the preschool years are a good thing. In fact, according to developmental psychologist David Elkind, United States society tends to push children so rapidly that they begin to feel stress and pressure at a young age. Elkind argues that academic success is largely dependent upon factors such as inherited abilities and a child’s rate of maturation, which parents can do nothing about. Consequently, children of a particular age cannot be expected to master educational material without taking into account their current level of cognitive development. In short, children require development appropriate educational practice, which is education that is based on both typical development and the unique characteristics of a given child.
