___ that may generally reduce the amount of labor needed on construction sites by 90 percent.

A．So clever the construction robots
B．Such construction robots are clever
C．So clever are the construction robots
D．Such clever construction robots are

C

解析試題分析：句意：建筑機(jī)器人如此聰明，以致于減少了在建筑工地需要的勞動力的90%。這里so …that,such…that 放在句首時(shí)，that前的句子用部分倒裝；so+形容詞或副詞+be+主語，故選C。
考點(diǎn)：考查的用法。
點(diǎn)評：本題難度適中。倒裝句是高中階段必須掌握的語法項(xiàng)目，它分為部分到裝和全部倒裝，情況復(fù)雜，需要考生熟記它們的用法。
即學(xué)即練：So difficult ____ it to work out the problem that I decided to ask Tom for advice.
A. I did find   B. did I find   C. I have found    D. have I found
解析：B。so difficult放于句首要引起主句的倒裝， 結(jié)果狀語從句中的“I decided to ask Tom for advice”表明整句話是針對過去的(不強(qiáng)調(diào)與現(xiàn)在的關(guān)聯(lián))， 不宜用現(xiàn)在完成時(shí)而應(yīng)采用一般過去時(shí)， 因此本題應(yīng)選B。

Teamwork is just as important in science as it is on the playing field or in the gym. Scientific investigations (調(diào)查) are almost always carried out by teams of people working together. Ideas are shared, experiences are designed, data are analyzed, and results are evaluated and shared with other investigators. Group work is necessary, and is usually more productive than working alone.

Several times throughout the year you may be asked to work with one or more of your classmates. Whatever teh task your group is assigned, a few rules need to be followed to ensure a productive and successful experience.

What comes first is to keep an open mind, becasue everyone’s ideas deserve consideration and each group member can make his or her own contribution. Secondly, it makes a job easier to divide the group task among all group members. Choose a role on the team that is best suited to your particular strengths. Thirdly, always work together, take turns, and encourage each other by listening, clarifying, and trusting one another. Mutual support and trust often make a great difference.

Activities like investigations are most effective when done by small groups. Here are some more suggestions for effective team performance during these activities: Make sure each group member understands and agrees to the task given to him or her, and everyone knows exactly when, why and what to do; take turns doing various tasks during similar and repeated activities; be aware of where other group members are and what they are doing so as to ensure safety; be responsible for your own learning, though it is by no means unwise to compare your observations with those of other group members.

When there is research to be done, divide the topic into several areas, and this can explore the issue in a very detailed way. You are encouraged to keep records of the sources used each person, which helps you trace back to the origin of the problems that may happen unexpectedly. A format for exchanging information (e.g. photocopies of notes, oral discussion, etc.) is also important, for a well-chosen method not only strengthens what you present but also makes yourself easily understood. When the time comes to make a decision and take a position on an issue, allow for the contributions of each member of the group. Most important of all, it is always wise to make decisions by compromise and agreement.

After you’ve completed a task with your team, make an evaluation of the team’s effectiveness — the strengths and weaknesses, opportunities and challenges.

We all know that everyone becomes a little more forgetful as they get older, but men’s minds decline more than women’s, according to the results of a worldwide survey.
General differences seem to be natural in male and female brains: Men are better at maintaining and dealing with mental images (useful in mathematical reasoning and spatial skills), while women tend to excel be good at recalling information from their brain’s files. Many studies have looked for a connection between sex and the amount of mental decline people experience as they age, but the results have been mixed.
Some studies found more age-related decline in men than in women, while others saw the opposite or even no relationship at all between sex and mental decline.
Those results could be improper because the studies involved older people, and women live longer than men: The men tested are the survivors, “so they’re the ones that may not have shown such cognitive(認(rèn)知的) decline,” said study team leader Elizabeth of the University of Warwick in England.
Scientists surveyed completed four tasks that tested sex-related cognitive skills: matching an object to its rotated form, matching lines shown from the same angle, typing as many words in a particular category as possible in the given time, e.g. “object usually colored gray”, and recalling the location of objects in a line drawing. The first two were tasks at which men are usually good; the latter are typically dominated by women. Within each age group studied, men and women performed better in their separate categories on average. And though performance declined with age for both genders, women showed obviously less decline than men overall.
【小題1】According to the passage, which of the following can NOT be typed into the same category?

A．cloudB．sheepC．treesD．goose
【小題2】Which of the following statements is true according the article? _______
A．Men do better than women when it comes to learning English.
B．Women stand out at remembering people’s names.
C．Women do well in dealing mathematic problems.
D．Men excel at typing as many words as possible in the given time.
【小題3】One important factor that affects the correctness of the results is that ________.
A．women live longer than men
B．people surveyed are all old
C．the old men tested may not have shown such cognitive decline
D．people taking part in this test came from all over the world
【小題4】The author aims to tell us that _________.
A．women’s minds perform better than men’s
B．men’s minds decline more with age
C．everyone becomes a little more forgetful as they get older
D．a(chǎn) survey on human’s mind decline was done recently

Learning English online is an effective way to improve your English. But with any type of learning you need to be prepared. This passage will give you advice and tips on how to get the most out of your online lessons.

This is an obvious point but also the most important one. A computer, a good Internet connection and a headset are what you will need to take classes online. A web camera is also pretty important.

     【小題3】     
When grammar or anything else is being taught, make sure that you understand it. You won’t need to practice it at this time; just make sure that everything is clear. If you don’t understand what is being taught, ask your teacher to explain it again. Your teacher will be more than happy to deal with whatever puzzles you.
Practice speaking English.
Every class is an opportunity to practice your English speaking with a native and qualified teacher. Try to allow the conversation to flow by listening and talking in a natural way. 【小題4】 The teacher should note the mistakes and correct them at a later time.

Curiosity is an important characteristic of a genius. You can’t find an intellectual giant who is not a curious person.
  【小題1】 This is necessary if you are to have a curious mind. Some things you know and believe might be wrong, and you should be prepared to accept things you don’t know or you don’t quite agree on.
  【小題2】 If you just accept the world as it is, you will certainly lose your “curiosity”. Try to discover what is beneath(在…下面) the surfaces of things around you.
Ask questions from time to time. A sure way to discover what is beneath the surface is by asking questions: What is that? Why does it make that way? How does it work? And so on. 【小題3】 
See learning as something that is fun. If you see learning as a burden, it will just make the burden heavier. But if you can find learning interesting, it will open another door.  【小題4】
