填空题 Many employees complain that they're being {{U}} {{U}} 1 {{/U}} {{/U}}while they work during the {{U}} {{U}} 2 {{/U}} {{/U}}. In a new survey of more than 900 major U.S. companies, nearly {{U}} {{U}} 3 {{/U}} {{/U}}of them acknowledged using a range of {{U}} {{U}} 4 {{/U}} {{/U}}methods to monitor their employees. And up to a quarter of the companies that monitor their workforce do it {{U}} {{U}} 5 {{/U}} {{/U}}. The number of employees being monitored has {{U}} {{U}} 6 {{/U}} {{/U}}in the last five years. There are two reasons for this, first, it's {{U}} {{U}} 7 {{/U}} {{/U}}; second, monitoring could be done {{U}} {{U}} 8 {{/U}} {{/U}}and efficiently. Most employers insist that these are {{U}} {{U}} 9 {{/U}} {{/U}}and even necessary business {{U}} {{U}} 10 {{/U}} {{/U}}. They have a {{U}} {{U}} 11 {{/U}} {{/U}}to know how {{U}} {{U}} 12 {{/U}} {{/U}}they provide is being used on the job. Monitoring can also be used to deter {{U}} {{U}} 13 {{/U}} {{/U}}, and for the workers' own {{U}} {{U}} 14 {{/U}} {{/U}}. But many attorneys are arguing that employees do not give up their {{U}} {{U}} 15 {{/U}} {{/U}}rights when they show up for work. Employees should always be {{U}} {{U}} 16 {{/U}} {{/U}}when they're monitored. Some employees even emphasize that there should be no monitoring whatsoever in purely {{U}} {{U}} 17 {{/U}} {{/U}}areas. Yet, so far there is only one state—Connecticut—that {{U}} {{U}} 18 {{/U}} {{/U}}surveillance in areas such as locker rooms or the employee lounge. There's only one federal {{U}} {{U}} 19 {{/U}} {{/U}}, the 1986 Electronic Communications Privacy Act, that {{U}} {{U}} 20 {{/U}} {{/U}}employee privacy.

填空题 Few of us realize how dust storms in the Sahara Desert can affect us directly in this country, but in fact, {{U}} {{U}} 1 {{/U}} {{/U}}can be felt many miles away. This has become more apparent in recent years as {{U}} {{U}} 2 {{/U}} {{/U}}with which dust storms occur has risen sharply. To understand how this situation {{U}} {{U}} 3 {{/U}} {{/U}}, you need to know something about the desert landscape. Under normal circumstances, there is {{U}} {{U}} 4 {{/U}} {{/U}}and lichen lying on top of the soft sand.

Of course, there are other contributing factors as well, the main two being {{U}} {{U}} 10 {{/U}} {{/U}}and deforestation on a large scale.

If you {{U}} {{U}} 13 {{/U}} {{/U}}, you can sometimes see red desert dust on the snow below! And this dust can {{U}} {{U}} 14 {{/U}} {{/U}}. It can, for example, carry cattle disease to distant places. In addition, {{U}} {{U}} 15 {{/U}} {{/U}}can fall on the sea, preventing the rays of the sun from {{U}} {{U}} 16 {{/U}} {{/U}}over large areas. Experts believe that the destruction of coral reefs in the Caribbean, {{U}} {{U}} 17 {{/U}} {{/U}}, can be traced back to this effect.

If you keep doing that long, if you 8 as much water out as naturally comes in, 9 the underground water level will 10 . In the underground systems there are natural discharge points.

填空题Today"s topic is an archaeological find. This recent archaeological find was really the most astonishing 1 !

And then, 3 , builders excavating the foundations for 4 in Yorkshire unearthed a limestone chamber with the remains of a chariot from that period! The chariot is 5 and from it we can deduce quite a lot about 6 . First of all, we know the chariot was 7 . It contained the skeleton of a man aged 8 , and this suggests that the chariot served a ceremonial, 9 . The hypothesis was borne out when it was discovered that it did not have matching wheels, so it could not have 10 . The chamber also contained the bones of over 250 cattle, and 11 can only be explained if the person interred in the chariot 12 , a tribal leader, in fact. Secondly, burials like this indicate a belief that in the afterlife a person would have 13 . Such beliefs were by no means confined to ancient Britain, of course; one immediately thinks of 14 .

We"re hoping that a place for the chariot will be found at the British Museum, if we can succeed in the very tricky task of lifting 20 .

填空题 Today's topic is the heather moors of Scotland. It's a sight that is {{U}} {{U}} 1 {{/U}} {{/U}}itself: the heather blooming on the moors {{U}} {{U}} 2 {{/U}} {{/U}}. But it is one that is becoming far less common. Rather alarmingly, the moors {{U}} {{U}} 3 {{/U}} {{/U}}, and nowadays only {{U}} {{U}} 4 {{/U}} {{/U}}is covered with heather, whereas in the not too distant past, this area was much greater, in the 1940s there was {{U}} {{U}} 5 {{/U}} {{/U}}heather than there is today. Why should any of this matter? Aside from the fact that {{U}} {{U}} 6 {{/U}} {{/U}}, does heather have any other value? The answer must be an emphatic yes. First of all, {{U}} {{U}} 7 {{/U}} {{/U}}would be very hard pressed to survive without it. In fact, twenty-one species are {{U}} {{U}} 8 {{/U}} {{/U}}. Secondly, the heather moors provide the backdrop for certain sports such as deer stalking, which constitute {{U}} {{U}} 9 {{/U}} {{/U}}for the rural economy. Thirdly, this small bushy plant features prominently among {{U}} {{U}} 10 {{/U}} {{/U}}, and as is the case in many countries today, tourism is an important source of revenue {{U}} {{U}} 11 {{/U}} {{/U}}. So, if the heather moors are {{U}} {{U}} 12 {{/U}} {{/U}}to Scotland, why have they been allowed to shrink so drastically? To a certain extent, the damage is due to mismanagement and {{U}} {{U}} 13 {{/U}} {{/U}}on the part of landowners: {{U}} {{U}} 14 {{/U}} {{/U}}is one of the major factors that have contributed to {{U}} {{U}} 15 {{/U}} {{/U}}of the heather moors. On top of that, large tracts have been cleared so that {{U}} {{U}} 16 {{/U}} {{/U}}. It is becoming increasingly obvious that something should be done to {{U}} {{U}} 17 {{/U}} {{/U}}as soon as possible. Now, there is no disputing the fact that {{U}} {{U}} 18 {{/U}} {{/U}}over a long period has been one of the main causes of the problem, so there is no reason why {{U}} {{U}} 19 {{/U}} {{/U}}to manage the heather moors properly shouldn't likewise bring positive results. Such programmes have recently got under way in certain areas, although it could be several years before {{U}} {{U}} 20 {{/U}} {{/U}}.
