We all think plants were expected to get larger with increased carbon dioxide in the atmosphere, but changes in temperature, humidity(湿度)and nutrient availability seem to have trumped the benefits of increased carbon dioxide” said researchers from the National University of Singapore.

45 percent of the species studied now reach smaller adult sizes than they did in the past. The researchers pointed out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for shrinking creatures.

“ We do not yet know the mechanisms(机制)involved, or why some organism are getting smaller while others are unaffected,” the researchers said. “Until we understand more, we could be risking negative consequences that we can’t yet quantify. ’’

The change is big in cold-blooded animals. Only two decades of warmer temperatures are enough to make retiles (爬行动物)smaller. An increase of only 1 degree centigrade caused nearly a 10 percent increase in metabolism(新陈代谢). Greater use of energy resulted in tiny tortoises and little lizards. Fish are smaller now too. Though overfishing has played a part in reducing numbers, experiments show that warmer temperatures also stop fish growing.

Warm-blooded animals aren’t immune(免除)from the size change caused by climate change. Many birds are now smaller. Soay sheep are thinner. Red deer are weaken And polar bears are smaller, compared with historical records.

This is not the first time this has happened in Earth’s history. 55 million years ago, a warming event similar to the current climate change caused bees, spiders and ants to shrink by 50 to 75 percent over several thousand years. That event happened over a longer time than the current climate change.

The speed of modem climate change could mean organisms may not respond or adapt quickly enough, especially those with long generation times climate change will be shown in the future.

A. they have found the exact causes for creatures getting smaller.

C. climate change has more negative effects on warm-blooded animals.

Ways to save time

We all wish we had just a bit more time. Just think what you could do with an extra hour or two each day: you could finally stick to an exercise routine, or spring-clean the house, or write your novel, or learn the guitar and so on.

1.But I can help you find more hours in your day for the things that really matter.

★Get Out of Bed Earlier.

If you normally get up at 7:30 a.m. try getting up at 7:00 a.m. That half-hour might not sound like much, but it could be time that you use to exercise, to read that book you've been meaning to finish.2.

★Do the Important Tasks First.

Once you get to work, get the important ones done first (not the easy ones, or even the urgent ones). 3.If you work like this, you’ll usually save time. The urgent tasks will still get done, and you won't miss the important ones.

★Reduce Interruptions.

If colleagues have a habit of hanging around your desk to chat, or if the phone is constantly ringing, you might find that it takes you half the day to finish a simple task like writing a letter.4.

★5.

A few minutes chatting, browsing the web, and so on, can easily turn into hours of wasted time over the course of a day. If your concentration is slipping, take a proper break: go and get a glass of water, or stretch your legs a bit. And if you’re facing a difficult task, try breaking it into small steps or stages so that it’s easier to deal with.

A. Stay Focused on Your Work.

B. Take Breaks When Necessary.

C. Would you want me to make your day longer?

D. I can’t magically make all your days 25 hours long.

E. Or simply to get your day off to a calm and organized start.

F. Constant interruptions don’t just eat up time, they also break your concentration.

G. You can afford to spend at least an hour working on big, important tasks rather than on all those little urgent ones.
