Don't you just love ice skating every winter? I am sure, that since winter is approaching, your skates are set to come out, just waiting to be used. Impress your friends with your new trick on how to ice -skate backwards with the help of these tips. Skating backwards on ice is a bit difficult but once you master the basic, there' s nothing like it. Follow the steps given below and you will be able to skate backwards in no time.

Stand Straight

The first thing that you need to do is, stand straight. If you feel that you are falling backwards, then just put your chin up and slightly bend your knees. Don't worry; this happens to all.

Confidence is What You Need

The most important step while learning how to skate backwards, is having enough confidence in yourself and in what you are doing. How can you achieve this? By practice. Just practice rolling backwards down a gentle slop every single day or just by pushing off from a wall or something of that sort. But before you do that, make sure that the place where you are practicing is free from any kind of debris (碎片) because otherwise, you could end up in the hospital due to some accident. While going backwards, just get used to the feeling of moving backwards. One of the important ice skating tips and techniques is that if you feel that you are losing your balance, then scissor (做剪式运动) your skates. Keep practicing this till you are confident about it.

Maintain Speed

Confident now? Great! Now the next step is to maintain your speed. While rolling in a straight line with one skate, with the other try sculling (滑浆), that is, keep pushing yourself backwards with an outwards stroke (滑动). Now bring the skate which you were using to scull, and then again, repeat the same process. Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling. Now, try the same thing using the other foot. Again keep doing this till you are confident enough.

Increase Your Speed Now

Once you are confident that you can scull with either foot, the next thing that you have to do is increase your speed. Try some of your own tricks now. Scull with either foot or with both at the same time.

Scull and Be Aware

While you keep one foot straight, keep sculling with the other. You can do that simultaneously (同时,一起) with both feet. Concentrate on what you are doing but don't get so involved that you don't see where you are going. If you are not watching your back, you might just bang against something or someone.

1.According to the text confidence comes from ______ .

A. constant exercise B. strict coaches

C. high speed D. good techniques

2.Which is the right order of ice - skating backwards?

a. Increasing your speed. b .Being able to scull with one foot.

c. Being about to stand straight. d. Trying some different tricks.

A. c→a→d→b B. c→b→d→a C. c→b→a→d D. a→c→b→d

3.In the last paragraph the author mainly wants to express ______ .

A. one must be brave to learn to ice - skate backwards

B. skating and keeping cautious are both important

C. it’s difficult to concentrate when ice - skating backwards

D. it' s a common thing to hit someone when ice - skating backwards

4.The purpose of the text is _____ .

A. to offer some advice on ice - skating backwards

B. to introduce the culture of ice-skating backwards

C. to explain advantages of ice - skating backwards

D. to compare different ways of ice - skating backwards

Grasshoppers are having to change their song — one of the iconic sounds of summer — to make themselves heard above the noise of road traffic, ecologists have discovered. The study, published in the British Ecological Society's journal Functional Ecology, is the first to show that human-made noise affects natural insect populations. Animals use sound to communicate for many reasons, including marking out territory, warning of predators and finding mates, and although previous research shows birds, whales and even frogs change their calls in noisy environments, the impact of human-made noise on insects has been neglected until now. Ulrike Lampe and colleagues from the University of Bielefeld in Germany caught 188 male bow-winged grasshoppers, half from quiet locations and half from beside busy roads. The grasshoppers use their song to attract mates.

The team then studied the differences in the two groups' songs in the laboratory. To encourage them to sing they exposed the males to a female grasshopper, and then recorded their courtship songs. Analysis of almost 1,000 recordings revealed grasshoppers living beside noisy roads produced different songs to those living in quieter locations.

According to Lampe: "Bow-winged grasshoppers produce songs that include low and high frequency components. We found that grasshoppers from noisy habitats increase the volume of the lower-frequency part of their song, which makes sense since road noise can mask signals in this part of the frequency spectrum(频谱)."

The team's findings are important because traffic noise could be upsetting the grasshopper's mating system(交配系统). "Increased noise levels could affect grasshopper courtship in several ways. It could prevent females from hearing male courtship songs properly, prevent females from recognizing males of their own species, or impair females' ability to estimate how attractive a male is from his song," Lampe explains.

Having discovered that human-made noise affects insect communication, the researchers now want to learn more about how the mechanism works, and whether the grasshoppers adapt to noise during their development as larvae(幼虫), or whether males from noisy habitats produce different songs due to genetic differences.

The bow-winged grasshopper is a common species in Central Europe. Adults occur mainly between July and September, preferring dry grasslands. Around 1.5 cm long, they vary in colour from green and browns to red and purple. The male's song consists of 2 second-long phrases that increase in amplitude (振幅) towards the end. The beginning of a phrase is characterized by slower ticking sounds that increase in speed and amplitude, leading to a buzzing sound towards the end of the phrase. A courtship song usually includes 2 phrases.

1.The author wrote the article to _________________.

A. introduce how grasshoppers make noises to attract mates.

B. raise the awareness of protecting bow-winged grasshoppers.

C. inform us of a recent discovery of ecological research.

D. warn us that human-made noise has changed ecological system.

3.What does the underlined word “impair” in the fourth paragraph mean?

4.Which of the following statements is true according the passage?

A. Road noise can cover the lower-frequency part of their song.

B. Animals make sounds only for the purpose of finding mates.

C. Grasshopper larvae learn to adapt to human-made noise.

D. Bow-winged grasshoppers grow up into adults in spring.
