题目内容

I give two examples as to why intelligent life may not actually exist, though I admit that for me, or even for a physicist who devoted his or her entire life to researching and studying the universe, it's shocking to claim that completely no life exists elsewhere.

Keeping that in mind, I'd just like to consider conditions elsewhere in the known universe. You really only need to look at our own solar system or the Earth at certain periods in its own history to appreciate that most places are much worse and much less suitable for life than our mild, watery globe.

So far, space scientists have discovered about seventy planets outside the solar. But it appears that if you wish to have a planet suitable for life, you just have to be very lucky, and the more advanced the life is, the luckier you'll have to be. I'm by no means a space observer, but I can recognize some particularly fortunate breaks we've had on the Earth. For example:

We are, to a degree, at the right distance from the perfect type of star, the one that is big enough to radiate a huge amount of energy, but not so big as to bum itself out quickly. Had our sun been ten times as huge, it would have burnt out completely after only ten million years, instead of ten billion and surely we would not exist. Too near, everything on the Earth would have boiled and withered away; any further, everything would have frozen over.

The universe is a surprising place, and our existence within it is a wonder. If a long and unimaginably complex sequence of events dating back 4.6 billion years or so hadn't happened in a particular manner at a particular time --if, to take just one example, the dinosaurs hadn't been wiped out by a meteor(流星)--we might still be a few centimeters long, with whisker(胡须) and a tail, and you'll be reading this in a cave somewhere.

1.What's the best title for this passage?

A. No Life Exists out of the Earth

B. Seventy Planets Discovered

C. A Place Full of Wonders

D. Perfect Conditions for Life

2.What makes the Earth more suitable for life than other planets in the solar system?

A. The Earth is the only planet that can receive energy from the sun.

B. The sun is at the right distance from us and in proper size.

C. The distance between the planets was neither too long nor too near.

D. The dinosaurs were no longer a threat to the Earth.

3.What does the underlined phrase "withered away" in the 4th paragraph mean?

A. Exploded.    B. Expanded.  C. Floated away.       D. Dried and died.

4.Where does the text probably come from?

A. A history book.     B. A magazine.  C. A science fiction.          D. A famous novel.

 

【答案】

 

1.A

4.B

【解析】

试题解析:本文叙述了作者的观点:除了地球之外再也没有星球上有生命存在,对此展开叙述,说明理由。

1.A主旨大意题。根据第一段最后一句话是点题句:it's shocking to claim that completely no life exists elsewhere. 声称完全没有生命存在于其它令人震惊,下文就此展开叙述,所以A正确。

2.B细节理解题。根据第四段第一句话We are, to a degree, at the right distance from the perfect type of star, the one that is big enough to radiate a huge amount of energy, but not so big as to bum itself out quickly在某种程度上我们距离这颗恒星在一个适当的距离,这个距离对于释放出巨大的能量是足够大的,但又不大到燃烧我们自己。所以B正确。

3.D词义猜测题。根据这个词的前后内容:Too near, everything on the Earth would have boiled and withered away; any further, everything would have frozen over.太近,地球上的所有都会被煮沸,再远一点,一切又会被结冰,所以本词与煮沸并列和相近,所以D正确。

4.B推理判断题。A. A history book历史书.B. A magazine.杂志         C. A science fiction.科幻小说           D. A famous novel.著名的小说。通读全文可以知道不属于历史,不是科幻,更不是小说,是一项科研成果:除了地球之外,再也没有生命存在,一个刊登在杂志上,所以B正确。

考点:考查科技类短文阅读。

Having one of those days—or weeks—when everything seems to annoy you? Even if you do nothing about it, your bad mood (心情)will probably go away after some time. But with a little effort, you can forget it much faster, often within a day or two.
Walk it off
Exercise is the most popular bad-mood buster. A person who’s in a bad mood has low energy and high tension. Taking a fast ten-minute walk, or taking some quick exercise can do wonders towards changing that bad mood.
Tune it out
Listening to your favorite music for a while can also make tensions go away quickly, because music starts associations with past positive experiences we’ve had.
Give yourself a pep talk
Stop and listen to what’s on your mind. Bad moods are often started by too many negative thoughts. Write them all down on paper, including the pessimistic(悲观的)messages you’ve been giving yourself and then give optimistic answers.(“I still don’t have a job.” Vs” I have two interviews next week.”)
Reduce your stress
Relaxation techniques are wonderful mood-lifters. There include de3ep breathing, stretching and visualizing, all of which sound complicated(复杂的)but aren’t. One easy way to visualize, close your eyes and picture a favorite place, such as the beach. Another simple way to unhappiness is to make a to-do list. One reason for being in a bad mood is feeling you have no options. By taking control over certain areas, you realize you’re not helpless. You can make changes in your mood and life.
Avoid things that won’t improve your mood
TV may not help much: you need to increase your energy level and stimulate(刺激)your mind-something that the TV show “Neighbors” won’t do. And before you reach for that piece of cake and coffee, think about how mood and food are linked. Sugar and caffeine contribute to depressed moods. The better choice? Research shows that carbohydrates, such as potatoes and pasta(面食), produce a calming effect on people who have a desire for them.
【小题1】Which of the following may help us stop a bad mood?

A.Draw a picture of something complicated.B.Put more sugar into your coffee.
C.Writing down negative thoughts.D.look ahead and write something positive.
【小题2】Why is it suggested that you close your eyes and picture the beach?
A.It helps raise your spirits.B.It brings us a new technique.
C.It is not complicated to do so.D.It is an area to be easily controlled.
【小题3】What can we infer from the passage?
A.You don’t have to be nice to your neighborsB.you often feel powerful when in bad mood
C.Some TV shows won’t energize youD.Slow exercise can gets you out of bad mood
【小题4】Which would be the best title for this passage?
A.How to Beat a Bad MoodB.Energy Level and Stress
C.Bad Mood and Our LifeD.How to Control Your Feeling

Do you like shopping? Or does the thought of wandering round the shops fill you with terror? For some of us,shopping is an enjoyable way of spending our spare time and our money. For me.it's something I would rather avoid.Thank goodness for the Internet! It's more convenient to buy CDs,electrical items,even food,from the comfort of your sofa.But that’s not the only reason:price is an important factor.We can buy goods and services cheaper online. But sometimes the problem is knowing what to buy.This has led to a type of shopping called “showrooming”.

Showrooming is something I've done.I will go to a shop to see,touch and try out products but then go home and buy them online at a knock—down price.I'm not alone in doing this.Research by a company called Foolproof,found 24%of people showroomed while Christmas shopping in 2013.

Amy Cashman,Head of Technology at TNS UK,says the reasons for this new shopping habit are that“people are lacking time,lacking money and they want security about the products they are buying.”She explains that consumers are not only shopping online at home but they are using the Internet in store or on their smartphones to shop around.

But does this mean technology will kill shops? Certainly shops will change.They will have to offer more competitive prices or encourage people to buy more by giving in—store discounts or free girls.

We mustn’t forget that buying in a shop means you can get expert advice from the sales assistant and you can get good aftercare.It’s good to speak to a real human rather than look at a faceless computer screen but at least by showrooming,you get the best of both worlds!
