Ⅰ.阅读理解(共两节)

第一节阅读下列短文，从每题所给的四个选项(A、B、C、D)中，选出最佳选项。

学习网An electric signal can trick a monkey’s brain into believing the animal’s finger has been touched.

Touch something，and your brain knows.The hand sends signals to the brain to announce contact was made.But that feeling of touch may not require making actual contact，tests on monkeys now show.Zapping brain cells can fool the animal into thinking its finger has touched something.

A person who has lost a limb or become paralyzed may need an artificial limb to complete everyday tasks.But such patients may not truly feel any objects they hold.The new findings point toward one day creating a sense of touch in those who use such artificial limbs.Psychologist Sliman Bensmaia of University of Chicago worked on the new tests.His team’s findings appeared on October 14 in the Proceedings of the National Academy of Sciences of the United States of America.

The sense of touch is crucial to everyday tasks：People without it may have difficulty cracking an egg，lifting a cup or even turning a doorknob.That’s why restoring it is a major goal for designers of artificial limbs.

In their new study，Bensmaia and his co­workers worked with rhesus monkeys (恒河猴)．The scientists implanted electrodes (电极)—small devices that can detect and relay an electrical signal—into the animals’ brains.The scientists used the electrode data to identify which neurons had become active.Then the scientists used the implanted electrodes to zap those same neurons.And the monkeys reacted as though their fingers had been touched.In fact，they hadn’t.

The monkeys couldn’t use words to tell the scientists what they had felt.Instead，they communicated by looking in a particular direction—just as when they had really been touched.

The new findings show how touch­sensitive devices could be built.The new study also offers “a nice clear pathway” for figuring out how to restore a sense of touch to an amputee (被截肢者) or someone with a injury of spinal cord.

The study shows how artificial limbs might be connected to the brain so that a person can “feel” with such a prosthesis (假肢)．But such a supersensory device doesn’t exist yet and scientists have a lot of work to do before people will benefit from it.Researchers must first figure out whether the electrodes would work in people in the same way they do in monkeys.

“I think the foundation is laid for human trials，” Bensmaia said.

【解题导语】本文是一篇科技文。文中介绍了一种新型的技术也就是电信号可以让人们的触觉产生错觉，即使是没有触摸到东西也有触感。这种技术可以为瘫痪或截肢病人带来方便。

1．What does the underlined word “it” refer to ?

A．The sense of touch.

B．An artificial limb.

C．The turning of a doorknob.

D．The lifting of a cup

解析：选A。细节理解题。第四段的首句说触觉对日常工作的完成至关重要，所以这里指的就是触觉。故选A。

2．Bensmaia tested monkeys to prove that the feeling of touch

.

A．is important to everyday tasks

B．may not require making actual contact

C．is a problem of life and death

D．may be a challenge for designers of artificial limbs.

解析：选B。细节理解题。根据第五段中的“And the monkeys reacted as though their fingers had been touched.In fact，they hadn’t.”可知，猴子以为他们摸到了东西其实并没有，所以触觉有的时候并不需要真正接触东西。故选B。

3．The last sentence of the text suggests humans

.

A．will use touch­sensitive devices

B．will test monkeys soon

C．lay foundations for monkey trials

初中学习网D．will be tested on the electrodes

解析：选D。细节理解题。根据文章末句“I think the foundation is laid for human trials”可知，人类应该做一下电信号的实验。故选D。

4．The passage is mainly about

.

A．restoring a sense of touch

B．fooling a clever monkey

C．making new artificial limbs

D．sending a signal with a touch

解析：选A。主旨大意题。本文主要讲的是电讯号会改变人的触觉，所以A选项“恢复触觉”符合题意。故选A。

第二节根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。

How to treat your guests at a dinner party

Almost everyone has attended a dinner party where they felt awkward.1.

So it’s very necessary to prevent unpleasant party situations for your guests with the following useful tips and find out how to treat your guests at a dinner party.

As guests arrive，greet them at the door saying “Hello” and ask how they are.2.

If there is a wine table，show them to the table and allow them to mix with other guests.

If a guest arrives who doesn’t know the majority of the people in the room，announce his presence and introduce him to everyone.3.

Be modest about your food even if the food is great.And don’t apologize either—your guests may think they shouldn’t try your food.Serve your guests or allow guests to serve themselves if food has been placed on a serving table.4.

Make sure that they are as comfortable as possible.

As you and your guests dine，play a “get to know each other” game.Have the guests go around the room and give a fun fact about themselves，their favorite things to do，where they would like to live and their worst or best cooking experience.5.

After the main course is served，offer your guests dessert.Have a dessert wine ready to serve in case a guest would like to pair wine with dessert.

A．This is a great ice­breaker as well.

B．This would help him feel more comfortable.
