七年级上册人教版英语周报答案2021一2022第二期

Researchers have developed new software using smart phones’GPS and imaging abilities that determine the exact location of distant objects as well as monitor the speed and direction of moving objects．The software could eventually allow smart phone-armed soldiers to target the location of their enemies．On the home front，the software could be used by everyone，including golfers judging distance to the green and biologists documenting the location of a rare animal without disturbing it．

“The great advantage of a Smartphone is that it provides so many tools in a single，readily available，relatively inexpensive package，”said Qia Wang，a doctoral student who led the development of the software．“For example，on the battlefield，a soldier needs a rangefinder，compass，GPS and other tools to get information before calling in an air strike．With our software，the soldier can have all those instruments in one device that can be purchased off the shelf．When that soldier returns from War，she can use the same Software to protect her family by clocking a speeder near her children’s school and catching the criminal on video．”

Wang and his colleagues developed their software to locate and track：

Targets of known size—when the size of the target is known．a single image is enough to pinpoint the target’s location．

Targets of unknown size—If the exact size of a target is unknown，the software uses two images to triangulate the location of the target·

Moving targets—By taking a short video of a moving target，the smartphone software can calculate how fast the target is moving and in what direction it is going.

“Currently，our software is limited by the physical abilities of smartphone hardware，but the devices are improving rapidly，”Wang said．“We expect that improvements in GPS accuracy，battery life and camera resolution will allow our software to make even more accurate observations．”

1.．From Paragraph 1 we can know that the new software can_______.

A．determine the speed of moving objects

B．1ocate objects in the distance exactly

C．defend soldiers against their enemies

D．help biologists protect rare animal

2.．The example given by Qia Wang is meant to ________________.

A．make an advertisement

B．describe the software briefly

C．show the benefits of the software

D．present the functions of smartphones

3.．How does the software calculate the speed of a moving object?

A．By taking a short video． B．By locating its position.

C．By taking a single image．D．By measuring real-life size.

4.．What’s Qia Wang’s attitude towards the future of the software?

A．Casual． B．Optimistic．

C．Cautious．D．Flexible

5.．What is the best title of the text?

A．Qia Wang，a Talented Doctoral Student

B．Use Smartphones to Their Full Potential

C．Targeting and Tracking With Smartphones

D．Smartphone-armed Soldiers on the Battlefield

An increase in students applying to study economics at university is being attributed to the global economic crisis awakening a public thirst for knowledge about how the financial system works.

Applications for degree courses beginning this autumn were up by 15% this January, according to UCAS, the Universities and Colleges Admissions Service. A spokesman for the Royal Economic Society said applications to do economics at A-level were also up.

Professor John Beath, the president of the society and a leading lecturer at St Andrews University, said his first –year lectures—which are open to students from all departments were drawing crowds of 400, rather than the usual 250.

“There are a large number of students who are not economics majors, who would like to learn something about it. One of the things I have done this year is to relate my teaching to contemporary events in a way that one hasn’t traditionally done.” He said.

University applications rose 7% last year, but there were rises above average in several subjects. Nursing saw a 15% jump, with people’s renewed interest in careers in the public sector(部门), which are seen as more secure in economic crisis.

A recent study showed almost two thirds of parents believed schools should do more to teach pupils about financial matters, and almost half said their children had asked them what was going on, although a minority of parents felt they did not understand it themselves well enough to explain.

Zack Hocking, the head of Child Trust Funds, said, “It’s possible that one good thing to arise from the downturn(衰退) will be a generation that’s financially wiser and better equipped to manage their money through times of economic uncertainty.”

1.Professor John Beath’s lectures are ___________.

A. given in a traditional way

B. connected with the present situation

C. open to both students and their parents

D. warmly received by economics

2.In the opinion of most parents, ___________.

A. economics should be the focus of school teaching

B. more students should be admitted to universities

C. the teaching of financial matters should be strengthened

D. children should solve financial problems themselves

3.What’s the main idea of the text?

A. Universities have received more applications.

B. Economics is attracting an increasing number of students.

C. College students benefit a lot from economic uncertainty.

D. Parents are concerned with children’s subject selection.
