4. 考查副詞詞義辨析。句意為:________,每個細(xì)胞只讀取它需要指令的一部分。However然而;Especially尤其是;Luckily幸運(yùn)地;Quietly安靜地。聯(lián)系上句“Each cell(細(xì)胞) in our bodies 3 some information in our DNA that acts as a kind of operating instruction.”可知,本句與上句之間是轉(zhuǎn)折關(guān)系。因此“However”用在這里符合語境,指每個細(xì)胞自身具有缺陷性。故選A。

5. 考查名詞詞義辨析。句意為:________會影響基因如何讀取指令嗎? study學(xué)習(xí);play玩耍;sleep 睡眠;sing唱歌。從上文“The Sleep Research Center at the University of Surrey found a direct link between the time of sleeping and genes.”可知選C。

【題目】Going to a friend’s house is very exciting. You may spend time with a friend and get to see where he lives. So remember to be polite.

When to arrive

The first thing to remember is that when a friend invites you to his/her house, you need to arrive on time. If your friend tells you to come “around 3:00”, that means you can arrive a few minutes after 3:00, but it is also a good idea to arrive at the right time.

What to bring

Often it is also nice to bring something to your friend’s house. This could be a box of chocolates for you two to share(分享), or maybe a movie that you can watch together. You can also bring some flowers. A little gift(=present) is a nice way to show your friend that you are excited to be at his house.

How to greet (問候)

When you visit your friend’s house, you may also meet his parents. You should tell them who you are and they may tell you their names. As a child, I went to visit my friend Paul. I called his parents by their first names John and Mary. But now I know it is more polite to call them Mr. or Mrs. Smith. This will show them more respect(尊重).
