Connectors

LANGUAGE FOCUS

Connectorsare words such asconsequently, however and soand phrases such as in addition, in fact and for example which are used to link clauses and sentences. (The Japanese economy has been very strong and consequently the yen has risen in value. In addition, the dollar has continued to show weakness. The pound, however, has remained steady.)

Focus structures are also used to link sentences. One type of focus structure is called fronting, In fronting, one part of a sentence (I can't eat asparagus) is moved to front position in order to focus attention on that part. (I can eat broccoli and carrots. Asparagus I can't eat. )

All those people who say that the weather has/t been normal recently are right. However, since there is really no such thing as normal weather, they probably mean something else. If they mean that average summer temperatures have been getting warmer, then they are certainly correct. In fact, it is not just the summer temperature, but the general average temperature of the whole world that has been steadily moving up.

The signs are everywhere. There are small signs. For example, butterflies in North America have moved about 60 miles north of where they used to live. There are also very large signs. Huge masses of ice in mountain glaciers and the Arctic are melting. The famous snow cap on Africa's Mount Kilimanjaro has almost disappeared. Actually, ice or snow doesn't really disappear, it turns into water, flows into the ocean and causes sea levels to rise.

Why is this happening? One answer is that it could simply be part of a natural process. After all, there have been long periods of warmth in the past. So we could just be experiencing another warming trend. This kind of answer had more supporter a few years ago. What scientists how believe is that human activity is the cause. For more than two hundred years, humans have been gradually changing the atmosphere, mainly as a result of industrial pollution. We have created an atmosphere around the earth that, like a giant glass container, lets heat6 from the sun through and holds it inside.

Will temperatures and sea levels keep rising? Should we just move to higher around and throw away our winter coats? The answer depends on where you live. If you live on the coasts of Florida, the answer is a definite yes. However, if you live in Northern Europe, your temperatures may soon be on the way down. All that fresh water pouring into the Atlantic will change the circulation patterns in the ocean. As a consequence, the current of air that flows towards Europe will become much cooler. According to one prediction, winter in London is going to become much more like winter in Copenhagen.
