- You must have missed the last train to Guangzhou the other day.

- Oh, no, I _____.

A. haven’t B. hadn’t C. don’t D. didn’t

D

【解析】

試題分析:考查對must have done用法的理解。must have missed,是對過去發生事情的推測,也就是所說的事情發生在過去,所以回答用一般過去時即可。而A,B選項易被誤選,注意這里的have done 并不單純地表示已經,現在完成的含義,要與must搭配來理解其真正含義。句意:-前幾天你肯定錯過了去廣州的最后一般火車吧。-哦,不,我沒有。故選D。

考點:考查對must have done用法的理解。

During the teenage years, hormonal (荷爾蒙的) changes lead to physical changes like rapid muscle growth, burst in height, and weight gain in both boys and girls. Take a look at the information and height and weight charts for teens presented in this article if the question “How much should I weigh for my age and height” is bothering you.

Average Height and Weight Charts for Teens

Faster growth in kids usually can be noticed at age 8. Genetic factors also determine the physical growth of a child. So, it is perfectly normal for two kids of the same age to have different weights and heights. The following figures should be used as guidelines only.

Ideal Body Fat Percentage

Fit men have 14% - 17% body fat.

Fit women have 21% -24% body fat.

Male athletes have 6% -13% body fat.

Female athletes have 14% - 20% body fat.

The ideal body fat percentage varies mainly according to age, sex and the physical activity of the individual. But it is a fact that some female athletes have body fat as low as 10 % and some male athletes had lower than 4% body fat. So, it can be observed that other than the above mentioned factors, genetic factors also influence the body-fat ratio.

Body Mass Index (BMI)

You may use the following formula to calculate your BMI:

As per SI Units (國際單位) : BMI = mass (kg)/[height (meters) ]2

Imperial (英制的) Units 1: BMI = mass (Ib. ) x703/[ height (in. ) ]2

Imperial Units 2: BMI = mass (Ib. ) x 4. 88/[ height (ft) ]2

Following conclusions can be derived from (得到) calculating the BMI:

BMI Calculated

Conclusion

BMI 18.5~25

BMI > 25

BMI < 18. 5

Underweight

BMI < 17. 5

Elephants are able to differentiate between ethnicities(種族) and sexes, and can tell an adult from a child --- all from the sound of a human voice.

This is according to a study in which researchers played voice recordings to wild African elephants.

The animals showed more fear when they heard the voices of adult Masai men.

Livestock-herding Masai people do come into conflict with elephants, and this suggests that animals have adapted to specifically listen for and avoid them.

The study is published in Proceedings of the National Academy of Sciences.

Prof Karen McComb and Dr Graeme Shannon from the University of Sussex led the study. They explained that in previous research they had used similar playback experiments to show that elephants could tell --- from the sound of a lion’s roar --- whether the animal was a female or a more dangerous male.

Prof McComb wanted to find out if the animals used their very sharp sense of hearing to identify a potential danger from humans.

The scientists recorded Masai men, women and children saying, in their own language, “Look, look over there, a group of elephants is coming”.

They also recorded Kamba men saying this phrase.

While cattle-herding Masai people often come across free-ranging elephants, which can result in violent conflict, the Kamba people’s more agricultural lifestyle does not generally bring them into aggressive touch with the animals.

When the team played recordings of these different voices through a hidden loudspeaker, they found that elephant family groups reacted more fearfully in response to the voice of a Masai man, than to a Kamba man’s voice.

And the adult male Masai voices encouraged far more of these defensive reactions than the voices of women or boys.

1.An elephant can tell a man from a woman by sense of ________.

A. touch B. sight C. smell D. hearing

2.How did the researchers get to know the elephants’ special ability of identification?

A. By observing the elephants in the zoo.

B. By playing voice recordings to them.

C. By recording the behaviours of elephants.

D. By communicating with them in a special way.

3.We can learn from the passage that elephants are especially afraid of ________.

A. Masai men B. Masai women

C. Kamba men D. Kamba women

4.What is the best title for the passage?

A. Elephants and human beings

B. Differences between human voices

C. Elephants recognise human voices

D. Elephants conflict with human beings
