Does mass _______________ (失業(yè)) depress wages? 

A study published Monday found that people who sleep less tend to be fat, and experts said it’s time to find out if more sleep will fight fatness.

“We’ve put so much emphasis on diet and exercise that we've failed to recognize the value of good sleep,” said Fred Turek, a physician at Northwestern University.

Monday’s study from Eastern Virginia Medical School in Norfolk covered 1,000 people and found that total sleep time decreased as body mass index - a measure of weight based on height - increased.

Men slept an average of 27 minutes less than women and overweight and fat patients slept less than patients with normal weights, it said. In general the fatter subjects slept about 1.8 hours a week less than those with normal weights.

“Americans experience insufficient sleep and fat bodies. Clinicians are aware of the burden of fatness on patients,” the study said.

“Our findings suggest that major extensions of sleep time may not be necessary, as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index,” it added.

“We caution that this study does not establish a cause-and-effect relationship between restricted sleep and fatness (but) investigations indicating success in weight loss via extensions of sleep would help greatly to set up such a relationship.”

The study was published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research.

In an interview, Turek said some studies have shown sleep causes declines in an appetite suppressing protein hormone, and increases in another hormone that causes a longing for food. In addition neuropathies（神經(jīng)療法）in the brain governing sleep and fatness appear to overlap（重疊）, he said.

Patness has been rising dramatically in developed countries and reached epidemic（流行�。� levels in the United States, it added, leading to a variety of health problems.

There was great excitement on the planet of Venus(金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.

The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20000 light years ago).

Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer (碟) landing on Earth. A press conference was held at the Venus Institute of Technology.

“We have come to the conclusion, based on last week’s satellite landing,” Prof. Zog said, “that there is no life on Earth.”

“How do you know this?” the science reporter of the Venus Evening Star asked.

“For one thing, Earth’s surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.” “What does this mean as far as our flying saucer program is concerned?”

“We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned.”

“Are there any other dangers that you discovered in your studies?”

“Take a look at this photo. You see this dark black cloud hovering(盤旋) over the surface of Earth? We don’t know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there.”

“Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.”

“If all you say is true, won’t this set back the flying saucer program several years?”

“Yes, but we shall continue as soon as the Grubstart gives us the added funds.” Prof. Zog replied.

During the week of great excitement the Venusian scientists succeeded in getting important information as to ____.

   A. the feasibility of landing a satellite on Earth

   B. the possibility of making a first-rate flying saucer

   C. the feasibility of sending a Venus Being to Earth

   D. the possibility of directing a flying saucer into Manhattan

According to Prof. Zog, the Venusians will have to take their own oxygen with them when they carry out their flying saucer program because ____.

   A. they need it in their way to the planet of Earth

   B. the Earth’s atmosphere is filled with deadly gases

   C. there is a low level of oxygen for Venusians

   D. there is no air on the planet of Earth

The “dark black cloud” on the photo refers to ____.

   A. the polluted air hovering over the surface of Earth

   B. the mass of tiny drops of water floating above Earth

   C. the mass of small things moving through the air

   D. the dark clouds gathering before a storm breaks

The author wishes to call our attention to the fact that ____.

   A. that modern man has polluted his environment to such an extend that he might destroy himself if he went on like this

   B. that there is a point in spending billions to land a flying saucer on Earth

   C. that pollution has become so serous a problem on Earth that even Venusians find life there unbearable.

   D. that it is difficult if not altogether impossible, to land a manned flying saucer on Earth

根據(jù)短文內(nèi)容，從下框的A – F選項(xiàng)中選出能概括每一段主題的最佳選項(xiàng)。選項(xiàng)中有一項(xiàng)為多余項(xiàng)。

Remembering names is an important social skill．Here are some ways to master it.

1.

When you hear a person’s name and want to remember it, repeat it．Immediately say it to yourself several times without moving your lips．You could also say the name again in a way that does not sound forced or artificial.

2.

You can let other people help you remember their names．After you’ve been introduced to someone, ask that person to spell the name and pronounce it correctly for you．Most people will be pleased by the effort you’re making to learn their names.

3.

Admitting that you can’t remember someone’s name can actually make people relaxed．Most of them will feel sympathy if you say “I’m working to remember names better．Yours is right on the tip of my tongue．What is it again?”

4.

    When meeting a group of people, concentrate on remembering just two or three names．Free yourself from remembering every one．Few of the people in mass introductions expect you to remember their names．Another way is to limit yourself to learning just first names．Last names can come later.

5.

    Consider going early to conferences, parties and classes．Sometimes just a few people show up on time．There are fewer names for you to remember．And as more people arrive, you can hear them being introduced to others — an automatic review for you.

She always ________（表現(xiàn)）well towards the customers．

The most common complaint about cellphones is that people talk on them to the annoyance of people around them. But more damaging may be the cellphone’s interruption of our thoughts.
We have already entered a golden age of little white lies about our cellphones, and this is in generally a healthy, protective development. “I didn’t hear it ring” or “I didn’t realize my phone had shut off” are among the lies we tell to give ourselves space where we’re beyond reach.
The concept of being unreachable is not new – we have “Do Not Disturb” signs on the doors of hotel rooms. So why must we feel guilty when it comes to cellphones? Why must we apologize if we decide to shut off the phone for a while?
The problem is that we come from a long-established tradition of difficulty with distance communication. Until the recent mass use of cellphones, it was easy to communicate with someone next to us or a few feet away, but difficult with someone across town, the country or the globe. We came to take it for granted.
But cellphones make long-distance communication common, and endanger our time by ourselves. Now time alone, or a conversation with someone next to us which cannot be interrupted by a phone, is something to be cherished. Even cellphone devotees, myself usually included, can’t help at times wanting to throw their phones away, or curse this invention.
But we don’t and won’t, and there really is no need. That we have the right to take back our private time is a general social recognition.
In other words, we don’t have to pay too much attention to the rings of our own phones. Given the ease of making and receiving cellphone calls, if we don’t talk to the caller right now, we surely will shortly later.
A cellphone call deserves no more importance than a word from the person next to us. Though the call on my cellphone may be the one-in-a-million from Steven Spielberg–who has finally read my novel and wants to make it his next movie. But most likely it is not, and I’m better off, thinking about the idea I just had for a new story, or the slice of pizza I’ll eat for lunch.
