【题目】Scientists in the United States say plant life has increased on Earth in the past twenty years and that in every area of plant growth the increase is the result of weather conditions.

Eight scientists from across the United States did the study. The space agency NASA and the Department of Energy paid for it. The findings were published in the magazine Science.

The researchers spent one and a half years examining weather satellite information. The information was recorded from 1982 to 1999. That period was one of the warmest on record. Researchers found that rainfall generally increased during that time.

The satellites measured the number of leaves on plants and the amount of sunlight taken in. The scientists used that information to estimate what is called net primary production. This is the total amount of carbon stored in land plants.

The scientists report a 6% increase in stored carbon since 1982. They say gains were high in equatorial areas, especially around the Amazon River in South America. The area alone had a 1 % increase in the net primary production.

The study was led by Ramakrishna Nemani of the University of Montana in Missoula. He says reduced cloud cover led to the growth in Amazon area. He also says the lack of clouds allowed more sunlight to get through. More sunlight meant increases in photosynthesis(光合作用. That is the process by which plants use energy from sunlight to produce the chemicals they need to grow.

Northern Canada, the north-central United States and northern Europe were second in increased plant growth. Ramakrishna Nemani says a rise in temperature helped plants there.

All together, the report says 25% of areas of plant life on Earth experienced increases. But the scientists also note the increase in the number of people on Earth and carbon dioxide levels in the atmosphere. Ranga Myneni of Boston University in Massachusetts, another study scientist says humans use about half the net primary production on Earth. And he notes that the world population grew by 36% during the period of time studied.

1 What's the main cause of the plant growth put forward by the study?

A. Growth in population.

B. Regional features.

C. Seasonal variation.

D. Weather conditions.

2 Which of the following is in charge of the study?

A. The space agency NASA of the US.

B. The Department of Energy of the US.

C. Ramakrishna Nemani in Missoula.

D. Ranga Myneni in Massachusetts.

3 Why do scientists believe that reduced cloud cover has led to the plant growth in the Amazon area?

A. Because plants could take in more sunlight.

B. Because plants could get more rainfall.

C. Because plants could enjoy cooler air.

D. Because plants suffer less from natural disasters.

4 Which of the following descriptions about the years from 1982 to 1999 is TRUE?

A. It was the warmest on record.

B. Rainfall decreased little by little.

C. World population grew by 25%.

D. Stored carbon increased by 6%.

【题目】Most people have a general list before a job interviewupdating a resume (简历 )ironing a professional suit, rehearsing an explanation for those two years spent after college. However, if tidying up the Facebook profile isn't on that list, maybe it should be.

According to a new study conducted by Harris Interactive for CareerBuilder. com45 percent of employers questioned are using social networks to screen people looking for jobs this yearmore than double from a year earlier, when a similar survey found that just 22 percent of employers were researc-hing potential hires on social networking sites like Facebook, MySpace, Twitter and Linkedln.

The study, which questioned 2667 managers and human resource workers, found that 35 percent of employers decided not to offer a job to a candidate based on the content uncovered on a social net-working site.

The report showed that Facebook was the most popular online destination for employers to do their online sleuthing(侦查),followed by Linkedln and MySpace. In addition7 percent followed job applicants on Twitter. More than half of the employers who participated in the survey said that provocative(挑衅的photos were the biggest factor contributing to a decision not to hire a potential employee, while 44 percent of employers aimed at references to drinking and drug use as red flags. Other warning signs included bad-mouthing of previous employers and colleagues and poor online communication skills.

While most of these may seem like obvious blocks, what consists of alarming behavior to a particular employer? Would photographs of a trip to the beach be considered inappropriate? To be on the safe side, it's probably wise to use the new privacy settings offered by Facebook to keep everything but the most innocuous(无害的content away from the public eye.

1 Your general list before a job interview should include all the following EXCEPT __________.

A. a written form of your education and previous jobs

B. preparing appropriate clothes

3 Why should the job seekers use the new privacy settings offered by Facebook?
