题目内容

Many gardeners believe that “talking” to their plants helps them grow---it turns out that they may not be crazy after all. According to the scientists from the University of Exeter, plants may keep communicating with each other through a secret “unseen” language.

For their experiment, the scientists picked a cabbage plant that is known to send out a gas when its surface is cut. In order to get video evidence of the communication, they changed the cabbage gene by adding the protein---luciderase(虫荧光素酶), which is what makes fireflies(萤火虫) glow in the dark.

When the changed cabbage plant was in full bloom, they cut a leaf off with a pair of scissors, and almost immediately, thanks to the luciderase, they could see the plant sending out “methyl jasmonate(茉莉酸甲酯)”.

While this was a known fact, what was surprising was the fact that the minute this gas began to give out, the nearby cabbage plants seemed to sense some kind of danger and started to send out a gas that they normally have to keep predators(捕食者) like caterpillars(毛虫) away.

What the scientists are not sure is whether the plants are trying to warn the other leaves or the near plants about the danger---something that will require further research However, the team, which is led by Professor Nick Smirnoff, is quite excited about the findings because this is the first time it has been proved that plants do not live a passive life, but actually move, sense and even communicate with each other.

However, before you get all concerned, they are quite sure that plants do not feel the pain when they are cut, since they do not have nerves---so go ahead and bite into that juicy carrot!

1.What’s the best title of the passage?

A. Plants Can Send Some Gas

B. Plants Can Communicate with Each Other

C. The “Unseen” Language of Plants

D. Plants Can’t Feel Pain

2. What does the underlined word “they” in Paragraph 1 mean?

A. Gardeners B. Plants

3.When the plant sent out methyl jasmonate, which of the following statements is NOT TRUE?

A. The nearby cabbage plants seemed to sense some kind of danger.

B. The nearby cabbage plants started to send out a gas.

C. The nearby cabbage plants tried to warn the near plants.

D. The nearby cabbage plants communicated through a secret language.

4.According to the experiment, plants ________________.

A. don’t live a passive life

B. can feel pain when they are cut

C. can warn the other leaves about danger

D. can talk with each other

Let's do some sleep math. You lost two hours of sleep every night last week because of a big project due on Friday. On Saturday and Sunday, you slept in, getting four extra hours. On Monday morning, you were feeling so bright-eyed, and you only had one cup of coffee, instead of your usual two. But don't be cheated by your energy: You’re still carrying around a heavy load of sleepiness, or what experts call “sleep debt”.

Sleep debt is the difference between the amount of sleep you should get and the amount you actually get. It’s a deficit that grows every time we remove some minutes off our nightly sleep. “People get more and more sleep debt without noticing it,” says William Dement, founder of the Stanford University Sleep Research Centre. Studies show that such short-term lack of sleep leads to a foggy brain, worsened eyesight, and trouble remembering. Long-term effects include obesity, and heart disease. A survey reports that we’re losing one hour of sleep each night—more than two full weeks of sleep each year.

The good news is that, like all debts, sleep debt can be paid off with some work. Adding an extra hour or two of sleep a night is the way to catch up. For the long-term lack of sleep, take it easy for a few months to get back into a natural sleep pattern(模式). Go to bed when you are tired, and allow your body to wake you in the morning naturally (no alarm clock allowed).

As you pay off sleep debt, your body will come to a rest at a sleep pattern that is particularly right for you. Sleep researchers believe that although the exact genes (基因) remain to be discovered, genes do determine our individual sleep patterns. That probably means you can’t train yourself to be a “short sleeper” and you’re fooling yourself if you think you’ve done it, so earn back that lost sleep and follow the orders of your inner sleep needs. When you put away sleep debt, you become a superman.

1.The example of sleep math is used to show___________.

A. how you build up your sleep debt

B. how you can pay off sleep debts at weekends

C. why you need enough sleep every night

D. why you should drink coffee to stay energetic

2. What does the underlined word “deficit” in paragraph 2 refer to?

A. full sleep B. light sleep

C. deep sleep D. lack of sleep

3.Those in sleep debt for a long time are likely to suffer from____________.

A. failing eyesight B. poor memory

C. weak heart D. weight loss

4.It’s impossible to train oneself to be a “short sleeper” because _________.

A. one can only get their energy during long sleep

B. how one sleeps is determined when they were born

C. one will feel tired if their sleep is less than needed

D. one sleeps more when developing a natural sleep pattern

The mayor was charged with _______ his power for personal benefits.

A good modern newspaper is an extraordinary piece of reading. It is remarkable first for what it contains: the range of news from local crime to international politics, from sports to business to fashion to science, and the range of comment and special features as well, from editorial page to feature articles and interviews to criticism of books, art, theatre, and music. A newspaper is even more remarkable for the way one reads it: never completely, never straight through, but always by jumping from here to there, in and out, glancing at one piece, reading another article all the way through, reading just a few paragraphs of the next. A good modern newspaper offers a variety to attract many different readers, but far more than any one reader is interested in. What brings this variety together in one place is its topicality(时事性) , its immediate relation to what is happening in your world and your locality now. But immediacy and the speed of production that goes with it mean also that much of what appears in a newspaper has no more than transient value. For all these reasons, no two people really read the same paper: what each person does is to put together, out of the pages of that day’s paper, his own selection and sequence, his own newspaper. For all these reasons, reading newspapers efficiently, which means getting what you want from them without missing things you need but without wasting time, demands skill and self-awareness as you modify and apply the techniques of reading.

1. A modern newspaper is remarkable for all the following except its ________.

A. popularity B. uniform style

A. people have different views about what a good newspaper is

D. different people prefer different newspapers

3. It can be concluded from the passage that newspaper readers _________.

A. apply reading techniques skillfully

B. jump from one newspaper to another

C. appreciate the variety of a newspaper

D. read a newspaper selectively usually

4. A good newspaper offers “a variety” to readers because __________.

A. it has to cover things that happen in a certain locality

B. readers like to read different newspapers

C.it tries to serve different readers

D. readers are difficult to please
