()2. —I have never seen a UFO. What about you?
—Me .

A.too
B.also
C.still
D.either

D

分析各选项用法：too用于肯定句句末；also用于句中；still表示“仍然”；either用于否定句句末，“Me either”是固定表达，用于否定情况的附和，此处前文是否定句，故选D。

()3. You have never visited the place before, you?

A.did
B.didn't
C.have
D.haven't

C

反义疑问句遵循“前否后肯”原则，陈述部分有否定词never，疑问部分用肯定形式；句子为现在完成时，助动词用have，主语是you，故疑问部分用have you，选C。

()4. —How long did you watch TV last night?
— the CBA match on CCTV5 was over.

A.When
B.As
C.Since
D.Until

D

问句询问昨晚看电视的时长，答语需表达“直到CCTV5的CBA比赛结束”这一含义。A选项When意为“当……时”，B选项As意为“因为；当……时”，C选项Since意为“自从；既然”，均不符合语境；D选项Until意为“直到……为止”，符合句意。

()5. Aunt Wang often asks her son too much meat.

A.not to eat
B.don't eat
C.not eat
D.to not eat

A

根据八年级英语固定搭配“ask sb. (not) to do sth.”（要求某人（不要）做某事），此处表达“王阿姨经常要求她儿子不要吃太多肉”，应使用not to eat，故选A。

() 6. —When should I hand in my paper?
—Your paper must as soon as the bell .

A.hand in; rings
B.hand in; will ring
C.be handed in; will ring
D.be handed in; rings

D

第一空，主语paper与hand in是被动关系，情态动词must后接被动结构be handed in，排除A、B；第二空，as soon as引导时间状语从句，遵循“主将从现”，从句用一般现在时，主语bell是第三人称单数，动词用rings，排除C。

()7. All the possible ways must the problem.

A.think of solving
B.be thought of solving
C.be thought of to solve
D.be thought to solve

C

主语All the possible ways是动作承受者，需用被动语态，排除主动形式A；固定短语think of不能省略of，排除D；此处表目的用不定式to solve，而非动名词solving，排除B，故选C。

()8. These words on the blackboard.

A.write
B.writes
C.is written
D.are written

D

主语These words是复数，且与动词write构成被动关系，需用一般现在时的被动语态，结构为“are+过去分词”，故此处用are written，选D。

四、完形填空
I'm delighted to be here at the Royal Society to give this speech.
Now, I'm 1 about the power of technology to make life better for everyone. 2, the easy speech for me to give would be to tell you about the incredible opportunities before us.
Just this morning, I was at Moorfields Eye Hospital. They' re using AI to build a model that can look at a single picture of your eyes, and not only diagnose（诊断）blindness, but also 3 heart attacks, strokes（中风）or Parkinson's（帕金森病）. And that's just the 4.
I do believe that technologies like AI will 5 a change as far-reaching as the industrial revolution, the coming of electricity or the 6 of the Internet. As with every one of those waves of technology, AI will bring new knowledge, new opportunities for economic（经济的）growth, new advances in human capability（能力）and the chance to solve problems that we once thought beyond us. But, like those 7, it also brings new dangers and new fears.
So, the responsible thing for me to do—the 8 speech for me to make—is to face those 9 head-on, giving you the peace of mind that we will keep you safe while making sure you and your children have all the opportunities for a better future that AI 10 bring.
Doing the right thing, not the easy thing, means being 11 with people about the risks from these technologies. So, I won't hide them from you. That's why today, for the first time, we've taken the highly unusual step of 12 our analysis on the risks of AI. These reports provide a serious warning. Get this wrong, 13 AI could make it easier to build chemical or biological weapons.
Criminals could use AI to spread fear and destruction on an even further scale. They could use AI 14 cyberattacks（网络攻击）, disinformation, fraud（欺诈）or even child sexual abuse（性侵害）. And in the most unlikely but extreme cases, there is even the risk that humanity could 15 AI completely through the kind of AI sometimes referred to as "super intelligence". So, while embracing AI's potential, we must also be aware of the very real dangers it presents.
